Plus, athletc antioxidant-rich foods will help you combat illness like a cold or the flu. Choose whole grain carbohydrates sources such as whole-wheat bread or pasta, and fiber-rich cereals as power-packed energy sources. Limit the refined grains and sugars such as sugary cereals, white breads and bagels.
You'll benefit more from whole-grain products. Choose healthy sources of protein such as chicken, turkey, fish, peanut butter, eggs, nuts and legumes. Stay hydrated with beverages, as a two percent drop in hydration levels can negatively impact performance.
Options include milk, water, percent fruit juice and sport drinks. However, realize that sport drinks and percent fruit juice tend to be higher in overall sugar content and, in the case of fruit juice, lack many of the health benefits present in its whole food counterpart.
Also, be sure not to confuse sports drinks such as Gatorade with "energy" drinks such as Red Bull and similar beverages. Stick with whole food options as much as possible as opposed to highly processed foods. Without adequate calories from the healthiest food sources, you will struggle to achieve your performance goals.
Plan a nutritious meal by choosing at least one food from each category. Healthy fat. Adequate hydration is a key element in sports performance. Most athletes benefit from developing a personal hydration plan.
A general rule for training is to consume a minimum:. Four to six ounces of fluid every 15 minutes of exercise. To properly assess, weigh yourself immediately prior to and after a workout. For every pound of weight lost, replace with 16 ounces of fluid. Best hydration choices include water, low-fat milk or percent juice.
Sports beverages are best reserved for competition, where quick hydration and electrolyte replacement are necessary. There are a few golden rules when it comes to eating on game day:.
It happens the days, weeks, and months leading up to the competition. Peak performance during competition means eating nutritious food while traveling. Relying on the concession stand for food during competition is an almost certain failure.
Players and parents should prepare by packing a variety of food and beverages. Choose energy-packed foods such as whole grain crackers with low-fat cheese, tortilla wraps with veggies and lean meat, hard-boiled eggs, vegetable or bean soups, small boxes of non-sugary cereal, fresh fruit, mini-whole wheat bagels with peanut butter, pita bread with hummus or pasta with grilled chicken.

| Eating for peak athletic performance | Here are some snack ideas: A peanut butter and honey sandwich on whole-wheat bread is a delicious way to get in carbohydrates, fiber, fats and protein between meals. A homemade Lunchable with crackers, cheese and deli meat is an easy, energy-sustaining snack. A tall glass of electrolyte-packed chocolate milk can replenish your body following an intense activity session. Pair a pack of fruit snacks with some nuts for a quick and convenient option. Monitor your hydration. Check your urine: Look at how much and what color your urine is. It should be a light yellow, like lemonade, not clear. Monitor your weight loss around practice: If appropriate, you can weigh yourself before and after you play. Weight loss during activity will generally only be from sweating. Train your gut. Here are some steps to take: Determine if you should be fueling during your training. You can use the guidance provided above or meet with a sports dietitian. Select the products you will be using on race day or during an event, such as sports drinks, gels or others. Choose carbohydrate-containing sports drinks and gels for sessions under hours. Solid foods work better for longer activity sessions. Begin practicing using the products early in your training, during activity sessions per week. This is not something to begin right before a competition or race. Gradually increase carbohydrates per hour each week until you hit your target. Most athletes may benefit from consuming grams of carbs per hour of training. Keep a journal of what you consume and how you feel. Note how it affects your energy, digestion, performance and recovery from training. Get advice from a sports dietitian familiar with intra-workout fueling. You may also be interested in.

The study goes on to suggest that it is not simply a matter of eating the correct type of foods as they point out that the specific time an athlete eats, and the amount they eat are of equal importance. To explain this approach, they have put forward the idea of the 3Ts — Timing, Type and Total. Timing — In an ideal world it is recommended that elite athletes consume food every three hours, and therefore establish a habit of eating smaller portions but more frequently. This gives the body the best opportunity to digest foods as efficiently as possible, and also ensures the athlete has a plentiful supply of energy inside their body. Whilst this is applicable to some athletes, it is not for every athlete and consideration needs to be given to the amount and type of carbohydrates given to certain players. Hence a player that has large quantities of either prior to training or playing could still have these carbohydrates remaining in their body after their exercise, which will turn into fat. Protein is extremely important to help muscles repair after exercise and to help muscles grow. It is recommended that an elite athlete consumes 2 grams of protein per kg of body mass per day, and includes protein in every meal consumed. Total — Depending on each individual athlete and their upcoming schedule of training and playing, the portion sizes may need to be reduced or increased to match their likely physical activity levels. It is important athletes are conscious of the amount of exercise they are undertaking and matching their food intake accordingly. Nutrition and athletic performance reminds us that. Eating a good diet can help provide the energy you need to finish a race, or just enjoy a casual sport or activity. You are more likely to be tired and perform poorly during sports when you do not get enough calories, carbohydrates, fluids, iron, vitamins and other minerals. |

Additionally, over-hydration can manifest through physical signs and symptoms such as weight gain, swelling of the feet and hands edema , nausea and vomiting, orthopnea sensation of breathlessness during sleep , low blood sugar, weakness, seizures, fatigue, headache, and increased urination 99 , This emphasises the importance of prioritising a balanced diet that will improve an athletes physical performance on gameday. A thletes, driven by the pursuit of peak performance, have been in the spotlight for numerous studies exploring how various dietary patterns optimize performance. Due to the high training demand of sports and recreational activities, it can be difficult to get enough fuel by consuming only 3 meals daily. Athletes can strategically incorporate whey protein into their post-exercise nutrition, recognizing its advantages while ensuring a balanced overall protein intake. |

| The Power of Nutrient-Rich Foods | Research on athletes finds this diet is linked to improved muscle power and endurance , as well as body composition. The low inflammatory index of this diet is also associated with enhanced recovery time. The ketogenic diet restricts the consumption of carbohydrates and protein to boost the use of fat as an energy source, thus improving weight loss and potentially athletic performance. While this may help athletes, such as wrestlers, who need to stay within specific weight requirements, the prolonged carbohydrate restriction can negatively affect training performance. Research has shown this restriction can increase baseline heart rates , perceived exertion , and rate of bone loss , harming short and long-term performance. However, research has not found significant decrements in performance for athletes following this diet. People often think that Ketogenic and Low-Carbohydrate diets are the same. A low-carbohydrate diet is less restrictive and does not restrict protein intake in the same way that Ketogenic diets would. Research has found that athletes on this diet have no differences in muscle strength and power compared to athletes following a regular diet. However, notable improvements in sprint times and exhaustion perceptions have been observed. As carbohydrates are restricted, the same detriments on performance found in ketogenic diet research may occur. Studies examining low-carbohydrate diets use extremely variable interventions that are difficult to compare. Thus, more research is needed to determine its specific impact on performance. Plant-based diets are also adopted by many athletes due to ethical or health-conscious reasons. This choice is supported by the literature , which suggests that vegetarian and vegan athletes perform just as well in terms of endurance and strength as their omnivorous counterparts. Following a plant-based diet can have numerous health benefits. Plant-based protein sources, such as tofu, lentils, and beans, have been found to improve circulation, reduce inflammation, lower oxidative stress, promote a healthy gut microbiome, enhance glycogen stores, and support leaner body weights. However, due to the restrictions of these dietary patterns, following them without proper planning may lead to nutritional deficiencies , such as protein, vitamins B12 and D, iron, zinc, calcium, total calories, and iodine. These deficiencies may affect performance, recovery, and bone health. In order to maximize a plant-based diet for training and competition, athletes may want to consult with a sports dietitian to ensure adequate nutrient intake and to get well-balanced examples of nutritionally fulfilling meals. Intermittent fasting, with its varying protocols, involves limiting the time window for eating during the day. This dietary pattern might not be suitable for athletes given their training schedules or the nutrition to fuel performance. As a result, the potential risks may outweigh the benefits. Limited eating windows may be helpful for weight loss or maintaining a strict weight class, but it can also lead to low energy availability and actually harm performance and overall health. The pressure to maintain a low body weight for athletics can lead to restrictive diets or even clinical eating disorders, affecting both physical and mental health. These include anorexia nervosa, bulimia nervosa, binge eating disorder, and orthorexia. Athletes , especially those in aesthetics-focused sports such as gymnastics, dance, and ice skating, have the highest rates of disordered eating and eating disorders. These eating patterns can weaken muscles, cause fatigue, and lead to injuries and complications like anemia and osteoporosis. Restrictive diets like ketogenic, plant-based, or intermittent fasting might appeal to athletes with disordered eating tendencies. Thus, athletes should carefully assess their motivations for diet changes and consult professionals to ensure their nutritional needs are met. To summarize, the researchers found that the Mediterranean diet has the most benefits for athletes regarding recovery and performance. As water is involved in the majority of chemical reactions involved in athletic performance it is therefore important that athletes are hydrated before, during and after physical activity to achieve their maximal physical performance. Hydration enhances your motor neurons. Your muscles move only when they receive commands from your brain. These commands move through neural pathways, which depend on adequate hydration to function at their best. When exercising, you need your motor neurons at their top potential — otherwise your speed and strength can decrease. Your body needs fluids to transport energy nutrients. Hydration helps regulate your body temperature. Your body is put under stress when its core temperature rises above normal. This stress interferes with the energy systems your body uses, which has negative effects on performance and recovery. Good sleep is essential to an athlete for maintaining high performance, body composition and general good health. Restricted sleep leads to hunger, impaired athletic performance, reduced psychomotor ability and a decline in health. Forget your elaborate rehab machines, ice baths and compression garments. Regular, good quality sleep is the best recovery tool for athletes there is. Athletes should aim for at least hours each night for optimal performance. More in periods of intense sports training and competition. Several previous studies in team sports have demonstrated that competitive success in competition is related to increased sleep duration and quality. In a recent study, elite male and female Brazilian athletes were asked to describe their sleep quality and mood immediately before a national or international competition. While the majority of participants rated their sleep quality as normal or good, poor sleep quality was an independent predictor of lost competition. This further emphasizes why athletes should understand the value of sleep in recovery and athletic performance, and constantly aim to improve their sleeping practices. As an athlete, if you ensure you have an adequate balanced diet, sufficient hydration with a sound balance of electrolytes, adequate sleep and the right warm up in the build up to training, gameday or competitions, chances are, you will achieve what is expected of you on the field and off it.

Sports nutrition for peak performance in academic and athletic pursuits. -
It is the key macronutrient for proper preparation for match day. Below is an example of what a typical athletes game day nutrition should look like with Kick Off according to Richard Allison. From the carbohydrate loading to having a balanced healthy diet in the weeks and days building up to gameday.
With proper hydration, your body will be able to perform at its best. Hydration for athletes is essential to maintain normal blood circulation because this aids the delivery of nutrients and oxygen to every working muscle in the body.
As water is involved in the majority of chemical reactions involved in athletic performance it is therefore important that athletes are hydrated before, during and after physical activity to achieve their maximal physical performance.
Hydration enhances your motor neurons. Your muscles move only when they receive commands from your brain. These commands move through neural pathways, which depend on adequate hydration to function at their best. When exercising, you need your motor neurons at their top potential — otherwise your speed and strength can decrease.
Your body needs fluids to transport energy nutrients. Hydration helps regulate your body temperature. Your body is put under stress when its core temperature rises above normal. This stress interferes with the energy systems your body uses, which has negative effects on performance and recovery.
Good sleep is essential to an athlete for maintaining high performance, body composition and general good health.

Opportunities for in-race nutrition: availability of drink stations. Typically every 5 km in elite races Frequency differs in large city races. Additionally, factors such as protein digestibility, digestion rate, and absorption kinetics are taken into account.
In the assessment of dietary protein quality, attention is often directed toward the indispensable amino acid composition offered by the protein source concerning human nutritional requirements.
Additionally, its capacity for digestion, absorption, and assimilation by diverse tissues throughout the body is considered Two categories of protein determine whether they include essential amino acids: complete and incomplete protein sources.
Animal protein is considered complete as it provides a comprehensive source of protein, containing all the required amino acids.
In contrast, plant-based proteins are incomplete sources as they lack some essential amino acids As highlighted in a comprehensive review 60 , biological values for prevalent plant sources typically fall within the range of 56—74, whereas various animal sources exhibit a spectrum spanning from 77 to on theoretical scales ranging from 0 to points.
A similar discrepancy is noted regarding values of net protein utilization; plant sources typically fall within the range of 53—67, while animal sources tend to be in the range of 73—94 on a point scale. The scores for Protein Digestibility Corrected Amino Acid stand out as one of the commonly utilized benchmarks for assessing protein quality 61 emerge as one of the most frequently employed metrics.
Casein, whey, and eggs achieve scores of in their respective categories, serving as examples of animal protein sources, whereas red meat scores In contrast, typical plant protein sources typically display Protein Digestibility Corrected Amino Acid stands values below , typically falling within the reported range of 45—75 Except for soy protein, which has a score of , other plant sources generally fall below this threshold.
Similarly, employing the DIAAS approach for evaluating protein quality reveals a consistent pattern: animal sources often exceed , in contrast, the majority of plant sources tend to be below this threshold.
When analyzing the amino acid profiles of different plant-based isolates in comparison to standard proteins derived from animal sources and specimens from muscles in the human skeletal system, it becomes clear that several sources of protein derived from plants do not contain adequate quantities of specific amino acids, such as lysine and methionine levels Moreover, they consistently exhibit reduced levels of indispensable and BCAA in contrast comparing animal protein sources to the amino acid composition present in human skeletal muscle.
Furthermore, elements such as vary depending on factors such as the type of nutrient, individual characteristics, and the specific physiological context notably affect the nutritional quality of a protein.
In essence, there is a general agreement that the transportation of amino acids to peripheral tissues from plant-based proteins is typically regarded as less efficient compared to that from animal proteins 64 , These distinctions are considered critical factors that influence the postprandial protein synthesis response observed in different tissues.
To promote muscle repair, remodeling, and improve post-exercise strength- and hypertrophy-related responses, it is crucial to ingest protein before, during, and after a workout Consumption of protein during these periods has been associated with a favorable impact on Muscle Protein Synthesis MPS Combining amino acids with carbohydrates before exercise can lead to peak rates of MPS, although the effects of protein and amino acid feedings during this period on exercise performance are not firmly established.
However, consuming carbohydrates combined with protein or essential amino acids during endurance and resistance training can have beneficial effects, including an improved anabolic hormonal status, reduced muscle damage, improved muscle cross-sectional area, and extended time to exhaustion It is important to note that protein has a limited capacity for the body to utilize as an energy source during activity, whereas carbohydrates are the primary fuel source.
Therefore, rehydration and intake of simple carbohydrates glucose are most important for athletes during exercise To enhance myofibrillar protein synthesis after exercise and minimize amino acid degradation, a nutritional recommendation advises incorporating 0.
Those pursuing this objective should strive to integrate this amount per meal A mixed meal consisting of carbohydrates and protein after exercise, with a carbohydrate-to-protein ratio of approximately 4 to 1, is recommended to initiate muscle glycogen synthesis However, the ideal timing for protein ingestion depends on individual tolerance as it may diminish over time after activity Using the following recommendations in Table 2 may help the athlete to assess their need for protein and prevent excessive intake and keep them on track Table 2.
Recommendation of protein intake based on the healthy athlete in different types of exercise and goals. To achieve optimal performance, athletes need to consume an appropriate amount of energy not only during exercise but also during recovery.
Fat oxidation primarily depends on oxygen, while carbohydrate catabolism can occur with or without oxygen. Consuming an adequate amount of fat is important, but high-fat or fat-loading diets are ineffective 76 , Athletes frequently turn to dietary supplements to boost metabolic capacity, delay the onset of fatigue, enhance muscle hypertrophy, and shorten recovery periods Omega-3, a type of PUFA, acts as a structural component within cell membranes of phospholipids.
Omega-3 plays a crucial role in the inflammatory response of the body Among athletes, Omega-3 has been linked to the postponement of onset muscle soreness, enhancement of anaerobic endurance capacity, improvement in oxygen efficiency during aerobic exercise, support for skeletal muscle health, and mitigation of exercise-induced oxidative stress It is recommended to take omega-3 after or with a high-fat meal for optimal absorption Athletes have employed a dietary strategy of increasing the proportion of dietary fat, primarily aiming to enhance intramuscular triglyceride stores.
The theory behind this approach suggests potential benefits for prolonged exercise performance while preserving glycogen stores Endurance athletes, in particular, have considered and applied this strategy to improve their performance in prolonged exercises.
Conversely, athletes focused on strength and power have given little thought to modifying fat intake in their training strategies.
Moreover, sustained enhancements in fat utilization were observed even following the implementation of a regimen for carbohydrate loading aimed at replenishing muscle glycogen levels. This dietary strategy suggests that a sequence of high-fat intake followed by carbohydrate loading might establish a conducive environment, enabling skeletal muscle to oxidize more fat while maintaining sufficient muscle glycogen.
Nevertheless, subsequent studies did not reveal improvements in exercise performance Certainly, there was a noted decrease in the rates of muscle glycogen utilization throughout the exercise bout Given the expectation that enhanced carbohydrate availability is likely to enhance power generation and exercise intensity, especially during the latter phases of prolonged exercise, these results were considered counterproductive.
While there has been extensive research on the effectiveness of high-fat diets, there is a general agreement that opting for a higher critical determinant, but rather, it depends on individual factors and the overall dietary context, an advisable approach to enhancing sports performance.
In an extensive review of the literature, Johnson provided insights into how a high-fat diet affects performance in physical activities. These adaptations encompass increased enzymes involved in the oxidation of fatty acids and improvements in both fatty acid transport and beta-oxidation; and 3 despite these mechanistic changes, improvements in exercise performance were not consistently observed, and in certain cases, a negative impact was evident While the suggestion of increasing dietary fat intake has been made for a positive impact on the utilization of substrates, the prevailing consensus discourages high-fat diets due to their adverse effects on performance.
Instances of reduced carbohydrate utilization and gastrointestinal discomfort further reinforce the argument against such dietary approaches. Whether the negative outcomes arise from the elevated consumption of dietary fat or the probable simultaneous decrease within dietary carbohydrate, the adoption of diets rich in fats is not recommended.
Micronutrients play a crucial role in sustaining life, encompassing vitamins and minerals that support well-being, development, and reproductive processes. These essential substances, required in small quantities, must be obtained through dietary intake as the human body cannot synthesize them Vitamins are categorized based on their solubility, with A, D, E, and K being fat-soluble, and B and C being water-soluble.
Minerals, on the other hand, are non-organic compounds contributing to physiological operations While a nutritionally balanced diet generally provides essential micronutrients in recommended doses for regular bodily functions, the appropriateness of these guidelines for athletes is a subject of debate.
Athletes often resort to micronutrient supplementation, with close to half of them incorporating vitamin or mineral supplements in their regimen, according to a meta-analysis When athletes have heightened overall energy requirements due to their training regimen, this increased need should reflect in both macro- and micronutrient intake.
Meeting this demand through a well-rounded diet aligned with recommended dietary reference intakes for vitamins and minerals is generally achievable However, certain scenarios, such as substantial losses through sweat and urine or specific dietary preferences, may lead to increased vitamin and mineral requirements In instances where athletes face challenges in meeting their micronutrient needs through diet alone, supplementation may be beneficial.
Athletes might consider external supplements to enhance well-being and performance, especially in situations like altitude training, where iron supplementation may be necessary 88 , Specific sports may present unique concerns, such as lower concentrations of vitamin D for athletes in winter sports or indoor activities Athletes consuming a diet rich in energy from nutrient-dense foods typically do not require vitamin and mineral supplements.
However, those who struggle to meet their micronutrient needs may benefit from supplementation, guided by a sports nutritionist 91 , It is crucial to replenish fluid loss during, before, and after exercise. Thirst is often not an effective indicator of dehydration, as 1.
Athletes are susceptible to losing 0. Consequently, fluid and electrolyte replacement should be incorporated into their recovery Fluid balance is fundamental for athletes, as hypohydration, which occurs when body water levels are lower than normal due to excessive sweating during exercise or diarrhea, can have life-threatening consequences and negatively impact performance On the other hand, during endurance exercise, increased consumption of mostly sodium-poor or sodium-free liquids, such as water, can lead to hyponatremia Excessive fluid consumption causes fluid retention in the body, resulting in dilutional hyponatremia Athletes should be aware that the body can lose fluids in various ways through sweating as a natural result of prolonged exercise, urination, and other factors such as temperature and humidity The physical signs and symptoms of dehydration include dry and poor skin turgor, dark urine color, rapid weight loss, dry and sticky mouth, weakness, fatigue, headache, sunken eyes, muscle cramps, an increased rate of injuries, difficulty in recovery, and a racing heartbeat 99 , Additionally, over-hydration can manifest through physical signs and symptoms such as weight gain, swelling of the feet and hands edema , nausea and vomiting, orthopnea sensation of breathlessness during sleep , low blood sugar, weakness, seizures, fatigue, headache, and increased urination 99 , Post-activity, the focus of hydration should be on rectifying any fluid deficits incurred during the practice or competition Sports drinks are primarily used to rehydrate and replenish essential electrolytes and other important components for athletes, such as magnesium, sodium, calcium, potassium, glucose, and fluids lost during strenuous exercise, to enhance endurance and performance On the other hand, the usage of sports drinks may differ based on the nature of the exercise.
The beverage hydration index model was introduced to evaluate the hydrating potential of a drink compared to plain water when individuals are at rest.
This model operates on the assumption that a beverage inducing greater diuresis than water results in less retained available fluid in the total body water pool, reflected by a beverage hydration index below 1.
Although a recent addition to beverage metrics, akin to the glycemic index for foods, the beverage hydration index has garnered replication by various research groups — since its inception Significantly, population-specific factors like body mass and sex seem to have negligible effects, and the reproducibility of the hydration index model is reported to be robust Consequently, the hydration index model has gained recognition as a reliable method for evaluating beverage hydration characteristics in well-controlled conditions, particularly when individuals are in a state of dehydration, as opposed to rehydration scenarios following exercise.
The addition of electrolytes to water seems to enhance fluid retention according to the beverage hydration index method , This aspect warrants further exploration, especially considering that sports drinks are commonly recommended for general public use as a suitable beverage for oral rehydration post-dehydration.
However, whether Pedialyte has a hydration index superior to a sports drink remains uncertain in some studies , , This aspect requires further investigation, especially considering that sports drinks are often recommended for general public use as a suitable beverage for oral rehydration after dehydration.
However, whether Pedialyte has a hydration index superior to a sports drink remains uncertain in some studies , In recent times, there has been a significant increase in attention devoted to nutritional supplements and ergogenic aids within the sports community.
Nutritional supplements are concentrated reservoirs of nutrients or other compounds exhibiting nutritional or physiological qualities beyond what is naturally obtained through a regular diet Ergogenic aids pertain to pharmaceutical substances employed to boost sports performance Recognizing a profitable market, commercial brands cater to high-performance athletes , university students , and young amateur athletes who enthusiastically supplement their diets with these products.
The growing prevalence of athletes using nutritional supplements and ergogenic aids has raised concerns among health and sports authorities. A significant number of these supplements and aids have been found to be contaminated with harmful or banned substances Such contamination could pose a risk to the health of athletes or lead to competition bans if the products contain prohibited doping substances While the utilization of nutritional supplements and ergogenic aids is common among athletes ranging from recreational to elite levels, only a select few ergogenic aids such as creatine, sodium bicarbonate, and caffeine have been proven to enhance sports performance Dietary supplements play a crucial role in building muscle, boosting the immune system, and providing fuel to enhance training or athletic performance.
Elite athletes often utilize performance-enhancing agents, with many considering supplements to be an essential component for sports success In this section, we will discuss the effectiveness of the most widely used supplements for improving physical performance.
Creatine stands out as the most frequently used and scientifically backed ergogenic aid , It holds a preferred status over other ergogenic aids due to its proven ability to increase power, enhance muscular strength, and promote an increase in fat-free mass, ultimately improving exercise and sports performance Recent studies highlight that creatine supplementation, with doses ranging from 0.
Additionally, creatine supplements have been shown to accelerate recovery from injury and muscle damage , Notably, a study demonstrated that introducing a preload at 0.
Previous research also suggests that creatine supplements can mitigate muscle damage resulting from prolonged, intense exercise sessions. Studies on creatine supplements consistently show enhanced performance and increased strength in short-duration, maximal-intensity exercises, as evidenced by improvements in metrics such as single-repetition maximum, muscular strength, repetitions, muscular endurance, speed, and overall strength , A meta-analysis examining the impact of creatine supplementation on upper and lower extremity performance revealed a noticeable increase in strength for both extremities Notably, performance improvement was observed in individuals following a creatine supplementation program, particularly in conjunction with resistance training.
Currently, the scientific literature strongly supports the utilization of creatine supplementation for boosting performance in short-duration, high-intensity resistance training, demonstrating a distinct influence on lean body mass.
Nevertheless, it remains unclear whether these effects of creatine supplementation translate into enhanced athletic performance.
Caffeine, a natural derivative stimulant, is associated with several proposed ergogenic effects. Known for its stimulating properties, caffeine not only improves performance but also increases the release of neurotransmitters, enhances intellectual ability, and boosts energy expenditure Studies indicate that caffeine serves as a potent ergogenic aid for both aerobic and anaerobic training, particularly benefiting endurance activities like cycling and running Another study demonstrated an approximate 3.
Several proposed mechanisms aim to explain the impact of caffeine supplements on athletic performance, focusing on their effects on endurance, muscle contraction, and perceived exertion , Additionally, the analgesic effect of caffeine reduces the perception of pain and effort during exercise, potentially serving as an additional mechanism, especially in exercises inducing discomfort , Consequently, reduced pain perception may contribute to sustained or increased motor unit firing rates, facilitating greater force production , The observation that high doses do not yield additional advantages suggests a dose—response relationship, emphasizing the need for moderation in caffeine consumption.
Amino acid supplements enjoy widespread popularity and are commonly utilized by highly-trained athletes. Beyond the realm of sports, amino acids offer potential therapeutic benefits, such as promoting healing, enhancing the immune system, preventing muscle atrophy in both the elderly and malnourished individuals, and contributing to the treatment of kidney and liver diseases Critical for maintaining a positive nitrogen balance in the body, amino acid supplements, including branched-chain amino acids and protein powder, play an essential role Approved by the FDA to counteract nitrogen loss, protein supplements are recognized as safe when used in accordance with good manufacturing or feeding practices REF Following resistance training, incorporating whey supplements may contribute to enhanced muscle building.
It is crucial to emphasize that immediately after resistance training, the consumption of a high-quality protein source promotes muscle growth and aids in recovery While whey supplements may be preferred over casein or soy in the immediate post-exercise period due to their faster absorption, there is no evidence suggesting that they result in greater muscle growth over a h period Additionally, whey protein has been associated with potential immune system benefits.
Participants taking whey supplements experienced a smaller drop in glutathione levels, linked to lower immunity, after a kilometer cycling time trial After intense exercise, additional protein is necessary to build new muscle proteins and repair damaged muscle cells Current recommendations from scientists suggest athletes should consume between 1.
The precise amount of protein required for muscle building has been a subject of debate, with strength and power athletes tending to consume at the higher end of this range 1. While the faster absorption of whey is advantageous immediately after training, the overall h impact on muscle growth appears comparable to other high-quality protein sources.
Athletes can strategically incorporate whey protein into their post-exercise nutrition, recognizing its advantages while ensuring a balanced overall protein intake. The best way to describe branched-chain amino acids BCAAs is as a combination of three out of the nine essential amino acids.
Valine, leucine, and isoleucine, the three BCAAs, cannot be synthesized by the body on its own These amino acids collectively constitute one-third of muscle proteins and play a pivotal role in the metabolism of skeletal muscle due to their distinctive properties BCAAs facilitate the absorption of blood sugar by muscle fibers and influence insulin signaling Notably, leucine is of particular importance among the three BCAAs, serving a crucial role in regulating muscle protein synthesis MPS and acting as a modulator even in the presence of hyperaminoacidemia Additionally, BCAA supplements operate through various mechanisms, including reducing soreness and preventing muscle tissue breakdown during resistance and intense training They contribute to the reduction of central fatigue, promote muscle function recovery, and maximize the MPS response According to some studies, incorporating BCAAs before and after exercise may effectively prevent exercise-induced muscle damage and increase muscle protein synthesis There is evidence suggesting that taking BCAA supplements before resistance training can also reduce delayed-onset muscle soreness and assist athletes in maintaining muscle mass during dieting However, it seems that endurance athletes may not significantly benefit from BCAA supplementation.
A study conducted at Florida State University indicated that while taking a BCAA supplement before and during prolonged endurance exercise reduced muscle damage, similar effects were achieved by consuming a sports drink with carbohydrates In essence, BCAAs do not appear to offer significant performance advantages during endurance exercises.
BCAAs, with a particular emphasis on leucine, play a crucial role in muscle protein synthesis and various aspects of muscle metabolism. The documented advantages of BCAA supplementation, such as reducing soreness, preventing muscle tissue breakdown, and enhancing recovery, align with their well-established role in supporting muscle function.
While BCAAs demonstrate potential benefits in situations like resistance training and muscle preservation during dieting, their advantages may not be notably pronounced in the context of endurance exercises. L-arginine, a non-essential amino acid naturally produced in the body, is commonly known by names such as arginine alpha-ketoglutarate A-AKG and arginine ketoisocaproate A-KIC Numerous studies suggest that the performance of elite athletes during anaerobic exercise remains largely unaffected by arginine supplements In a study focused on A-AKG supplements, athletes did not exhibit differences in nitric oxide NO levels, blood flow, or performance However, a review of multiple studies indicated that arginine supplements might offer a modest benefit to novice athletes but not to more experienced athletes or female athletes While arginine is a naturally occurring amino acid, its supplementation seems to have a limited impact on elite athletes during anaerobic exercise, as suggested by several studies.
The potential modest benefit for novice athletes, highlighted in a review, prompts further investigation into factors such as experience level and gender that may influence the effectiveness of arginine supplementation.
The specified safe dose serves as a reference for individuals considering incorporating arginine into their nutritional regimen. Beta-alanine, a non-essential amino acid naturally produced in the body, increases muscle carnosine concentrations when taken as a supplement Elevated muscle carnosine levels enhance buffering capacity, reducing lactic acid buildup during high-intensity exercise, which can improve performance in sprints and short distances by mitigating fatigue A systematic review of 19 randomized controlled studies has confirmed that beta-alanine supplements enhance performance in short, high-intensity activities Analyzing 15 studies revealed an average performance improvement of 2.
Many studies utilize daily doses of 3. Beta-alanine supplementation has demonstrated efficacy in enhancing performance in short, high-intensity activities through increased muscle carnosine levels. The systematic review and specific studies provide robust evidence of its positive impact on various athletic parameters.
The recommended dosage strategy underscores the significance of both the initial loading phase and the subsequent maintenance dose for optimal results. Athletes and individuals involved in high-intensity activities may consider beta-alanine supplementation as part of their performance enhancement strategy In summary, sports supplements lack systematic regulation, and there is no guarantee that they fulfill their claims or do not contain prohibited substances.
Major sports organizations, including United Kingdom Sport, the US National Collegiate Athletic Association, and the International Olympic Committee IOC , have policies advising against the use of sports supplements It is recommended to prioritize a healthy diet and consult with your medical team or sports nutritionist before considering any supplements Further research is essential to comprehend the combined effects of various sports supplement intake.
Nutrient timing involves strategically providing the appropriate macronutrients when the body is most primed to utilize them effectively In the context of exercise, nutrient timing can be segmented into three distinct phases: the energy phase, the anabolic phase, and the adaptation phase.
The energy phase encompasses the period right before and during the exercise itself. This period, often referred to as the anabolic or metabolic window , highlights the heightened responsiveness of exercised muscles to nutrient intervention. Subsequent to the anabolic phase, the adaptation phase unfolds.
Consistently incorporating suitable supplements and meals during this period sustains an improved response to nutrient intervention for an extended duration. This fosters quicker recovery and facilitates training adaptation, enhancing overall exercise performance.
During this period, the primary objective of nutrient consumption is to ensure an adequate fuel reserve for the muscles, thereby enhancing performance during the exercise. Explorations into pre-exercise nutrition trace back to the s, when researchers began investigating physiological reactions during exercise in response to the intake of pre-exercise carbohydrates CHO , such as glucose and fructose As research progressed, studies delved into manipulating exercise performance through pre-exercise nutrition strategies.
An early study involving trained swimmers, employing different nutritional strategies, including supplemental cane sugar, did not reveal significant differences in performance However, this study laid the groundwork for subsequent interventions and explorations in the field.
Hargreaves et al. However, these differences were not statistically significant when compared to meals with equivalent energy content comprising either 45 or grams of carbohydrates In a separate study, significant improvements in a similar performance task were observed when recreationally trained individuals ingested either 1.
Interestingly, no significant distinctions were noted between the two CHO doses In summary, the collective influence of pre-exercise carbohydrate intake on endurance performance generally appears favorable, although findings across studies can be inconsistent. Interpretation of results should consider methodological aspects, including factors like the time elapsed since the last intense training session and existing muscle glycogen levels, which are interconnected and can influence the effectiveness of pre-exercise feeding.
The significance and performance-enhancing benefits of pre-exercise carbohydrates may be contingent on muscle glycogen content before feeding. This suggests that individuals with limited rest between training sessions may derive greater benefits compared to those with extended rest periods, provided they adequately consume carbohydrates.
While much of the research has focused on aerobic exercises, there is growing evidence that activities involving high-intensity intervals, such as resistance exercise, may also experience advantages. These activities predominantly rely on glycolytic, fast-twitch muscle fibers, which generate force through rapid muscular contractions fueled by stored phosphagens and anaerobic glycolysis, leading to lactate production.
Importantly, substantial evidence indicates that pre-exercise supplementation with carbohydrates can mitigate glycogen reductions, even if it does not notably impact blood glucose levels Carbohydrate CHO intake during physical activity has been extensively studied since the s Insufficient CHO in these scenarios can lead to decreased exercise intensity due to a shortage of efficient fuel, diminished calcium release, and increased fatigue , Inadequate carbohydrate intake during such activities may result in decreased exercise intensity due to a shortage of efficient fuel, diminished calcium release, and increased fatigue.
Excessive CHO intake, on the other hand, may lead to gastrointestinal upset, potentially impeding performance goals. Diversifying CHO ingestion with different transporters can enhance CHO uptake and oxidation to approximately 1.
This varied CHO consumption not only improves CHO availability without causing gastrointestinal upset but also carries the potential to enhance overall performance Importantly, fructose ingested at a rate of 1. These results highlight the potential benefits of integrating varied carbohydrate CHO intake to enhance performance — , , An alternative approach to optimizing carbohydrate CHO delivery, with the goal of minimizing gastrointestinal distress and potentially boosting performance, involves the simultaneous intake of protein and CHO.
Recent findings from a review and meta-analysis indicated positive performance outcomes, especially in time trials or efforts to exhaustion, for groups consuming a combination of CHO and protein compared to CHO alone The noted favorable effect persisted consistently, even with the utilization of non-isocaloric supplements.
However, when ensuring that CHO and protein supplements were equivalent in CHO content and subsequent examination of the effects of isocaloric supplementation involving both CHO and protein or CHO alone on time to exhaustion, no notable differences were observed Although the simultaneous ingestion of protein and carbohydrates may not yield immediate performance improvements, there are indirect advantages.
These encompass the capacity to boost caloric intake while reducing carbohydrate consumption to prevent gastrointestinal distress, enhancing amino acid bioavailability to reduce muscle protein breakdown, and improving amino acid availability for gluconeogenesis.
Moreover, co-ingestion may play a role in postponing central nervous system fatigue The effectiveness of intra-exercise nutrition, especially the consumption of carbohydrates CHO , is highly contingent on variables like pre-exercise feeding, glycogen status, and the type of exercise This strategy maximizes the uptake and oxidation of CHO while simultaneously preserving muscle glycogen.
In competitive scenarios, where extended endurance events frequently conclude with a sprint to the finish line, relying significantly on anaerobic metabolism and the utilization of endogenous muscle glycogen, the prudent conservation of this fuel source throughout the entire bout becomes paramount.
After engaging in physical activity, individuals commonly experience a temporary surge. During this phase, there is an increase in fatigue, muscle soreness, and a decline in performance.
In this stage, catabolic processes take precedence, leading to decreased insulin levels, restricted glycogen, and limited substrate availability.
Cortisol and catecholamines collectively influence physiological processes in the body, heightening the pace at which muscle protein is being broken down The intake of carbohydrates and protein post-exercise offers the potential to raise glucose levels in the bloodstream, reduce cortisol levels, and improve substrate availability, enabling the transition from a catabolic state to a more anabolic condition Additionally, activating muscle GLUT4 transporters, increasing glycogen synthase activity, and enhancing insulin sensitivity all contribute to improving how responsive skeletal muscles are to absorbing carbohydrates and amino acids 50 , Therefore, the post-exercise period offers a strategic opportunity for nutrient intake to aid in replenishing muscle glycogen, promoting protein synthesis, and reducing the degradation of muscle proteins , Integrating the timing of nutrient intake after exercising into a training routine becomes essential for optimizing recovery rates and maximizing the benefits of training.
During moderate-to-high intensity exercise, muscle glycogen assumes a crucial role as the primary source of energy to sustain physical activity. In light of this situation, precise post-exercise nutrient timing becomes vital, emphasizing the primary goal of replenishing muscle glycogen to hasten the recovery process.
After physical activity, there is a decrease in the heightened levels of post-exercise glucose transporters, which are crucial for the absorption of nutrients. This decline brings the transporter levels back to baseline within a two-hour period Aside from glycogen synthesis, the consumption of protein and essential amino acids following exercise plays a pivotal role in triggering muscle protein synthesis and aiding in the reconditioning of skeletal muscles After exercising, there is a notable increase in muscle damage and protein degradation in the aftermath of exercise , Moreover, when glycogen stores are depleted, the pace of protein breakdown increases, as amino acids could potentially undergo gluconeogenesis to be utilized in replenishing levels of glycogen As a result, it is crucial to consume protein after exercise to mitigate the breakdown of proteins and assist in the repair of muscle damage When aiming to stimulate muscle protein synthesis, proteins that are rapidly digestible and of high quality, containing an adequate amount of essential amino acids, may be more effective than proteins with lower quantities of branched-chain amino acids or those that are slower to digest Comprehensive training and maintaining a sufficient daily protein intake are crucial for achieving strength and hypertrophy.
However, beyond these foundational aspects, there are potential advantages to carefully considering the timing of protein consumption, especially immediately after exercising. The positive impacts on net protein balance and glycogen synthesis underscore the significant benefits of ingesting protein in the post-training period.
Fundamentally, critical factors contributing to optimal performance include not only the quality of the training but also the overall protein intake throughout the day.
The strategic timing of protein consumption provides an additional layer of support to boost performance. Even if the resulting benefits are seemingly minor, this aspect becomes a pertinent factor, particularly for competitive athletes who are dedicated to optimizing their performance. In summary, the significance of nutrient timing is a nuanced matter, and its relevance varies greatly depending on the context.
Defined as the delivery of adequate macronutrients precisely when the body is ready to use them , nutrient timing represents a dietary approach where specific nutrients are ingested before training to enhance both short-term performance and long-term adaptations Early research delved into the effects of acute carbohydrate CHO consumption on exercise performance, focusing on glycogen depletion and use during moderate to high-intensity aerobic activity , Subsequent studies broadened the scope to investigate how acute protein consumption PRO impacts endurance and resistance workout performance, as well as recovery and adaptation.
The energy phase during a workout is crucial as muscles require sufficient energy for contractions. The benefits encompass a good supply of glycogen, a reduction in cortisol, and assistance in preparing muscle enzymes for faster recovery , Post-workout nutrition timing is widely regarded as the most crucial phase.
Consuming the right balance of nutrients during this time initiates the healing process for injured tissue and replenishes energy stores. This occurs in a super-compensated manner, enhancing exercise performance and body composition.
In conclusion, this narrative review offers targeted recommendations for addressing the nutritional needs of the active population, with a specific focus on preventing disordered eating. Given the unique challenges faced by athletes, it is imperative to tailor nutrition plans to individual requirements.
Individualization emerges as a cornerstone in preventing disordered eating among athletes. Recognizing diverse goals, body compositions, metabolic rates, and dietary preferences is essential. Tailoring nutrition plans to accommodate these individual factors can significantly contribute to optimizing performance while mitigating the risk of disordered eating Macronutrients, which include carbohydrates, proteins, and fats, play a critical role in athletic nutrition.
Adequate carbohydrate intake is necessary to support energy production and replenish glycogen stores, thereby reducing the likelihood of restrictive eating behaviors Proteins are indispensable for muscle repair and growth, emphasizing the importance of meeting increased protein needs without resorting to excessive dietary restrictions Meanwhile, healthy fats contribute to sustained energy, hormone production, and overall health, promoting a balanced approach to nutrition.
In addition to macronutrients, micronutrients, encompassing vitamins and minerals, are paramount for energy metabolism and immune function. Promoting a diverse, nutrient-dense diet is crucial to ensuring athletes receive adequate micronutrients, thereby reducing the risk of nutritional deficiencies that might contribute to disordered eating Hydration emerges as a key factor in preventing disordered eating among the active population.
Proper fluid balance is essential for physiological function, and athletes must be attuned to their individual fluid needs. Maintaining adequate hydration levels before, during, and after exercise is crucial, as dehydration can exacerbate disordered eating behaviors.
While acknowledging the interest in sports nutrition supplements, caution is advised. Athletes should prioritize meeting their nutritional needs through whole foods to minimize the risk of disordered eating patterns Supplements should only be considered when dietary intake falls short or specific deficiencies are identified.
Consultation with qualified professionals is essential to ensure safe and appropriate usage. In summary, implementing these targeted nutritional recommendations can serve as a proactive tool in preventing disordered eating within the active population.
By understanding and addressing the unique challenges faced by athletes, promoting individualization, and emphasizing a balanced and informed approach to nutrition, this review contributes to the overarching goal of investigating and preventing disordered eating in the active population.
This review delves into the most recent research findings on nutritional recommendations for athletes, offering readers a comprehensive overview of the current state of the field.
