Top 11 Superfoods For Endurance Athletes - Healthy Foods For A Balanced Diet

Endurance nutrition for performance enhancement -

Athletes who exercise strenuously for more than 60 to 90 minutes every day may need to increase the amount of energy they consume, particularly from carbohydrate sources.

The current recommendations for fat intake are for most athletes to follow similar recommendations to those given for the general community, with the preference for fats coming from olive oils, avocado, nuts and seeds.

Athletes should also aim to minimise intake of high-fat foods such as biscuits, cakes, pastries, chips and fried foods. After absorption, glucose can be converted into glycogen and stored in the liver and muscle tissue.

It can then be used as a key energy source during exercise to fuel exercising muscle tissue and other body systems. Athletes can increase their stores of glycogen by regularly eating high-carbohydrate foods.

If dietary protein intake is insufficient, this can result in a loss of protein muscle tissue, because the body will start to break down muscle tissue to meet its energy needs, and may increase the risk of infections and illness.

Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise. More refined carbohydrate foods such as white bread, jams and lollies are useful to boost the total intake of carbohydrate, particularly for very active people.

Athletes are advised to adjust the amount of carbohydrate they consume for fuelling and recovery to suit their exercise level. For example:. A more recent strategy adopted by some athletes is to train with low body carbohydrate levels and intakes train low. There is accumulating evidence that carefully planned periods of training with low carbohydrate availability may enhance some of the adaptations in muscle to the training program.

However, currently the benefits of this approach to athletic performance are unclear. The GI has become of increasing interest to athletes in the area of sports nutrition. However, the particular timing of ingestion of carbohydrate foods with different GIs around exercise might be important.

There is a suggestion that low GI foods may be useful before exercise to provide a more sustained energy release, although evidence is not convincing in terms of any resulting performance benefit. Moderate to high GI foods and fluids may be the most beneficial during exercise and in the early recovery period.

However, it is important to remember the type and timing of food eaten should be tailored to personal preferences and to maximise the performance of the particular sport in which the person is involved. A high-carbohydrate meal 3 to 4 hours before exercise is thought to have a positive effect on performance.

A small snack one to 2 hours before exercise may also benefit performance. It is important to ensure good hydration prior to an event. Consuming approximately ml of fluid in the 2 to 4 hours prior to an event may be a good general strategy to take.

Some people may experience a negative response to eating close to exercise. A meal high in fat, protein or fibre is likely to increase the risk of digestive discomfort. It is recommended that meals just before exercise should be high in carbohydrates as they do not cause gastrointestinal upset.

Liquid meal supplements may also be appropriate, particularly for athletes who suffer from pre-event nerves. For athletes involved in events lasting less than 60 minutes in duration, a mouth rinse with a carbohydrate beverage may be sufficient to help improve performance.

Benefits of this strategy appear to relate to effects on the brain and central nervous system. During exercise lasting more than 60 minutes, an intake of carbohydrate is required to top up blood glucose levels and delay fatigue. Current recommendations suggest 30 to 60 g of carbohydrate is sufficient, and can be in the form of lollies, sports gels, sports drinks, low-fat muesli and sports bars or sandwiches with white bread.

It is important to start your intake early in exercise and to consume regular amounts throughout the exercise period. It is also important to consume regular fluid during prolonged exercise to avoid dehydration.

Sports drinks, diluted fruit juice and water are suitable choices. For people exercising for more than 4 hours, up to 90 grams of carbohydrate per hour is recommended.

Carbohydrate foods and fluids should be consumed after exercise, particularly in the first one to 2 hours after exercise. While consuming sufficient total carbohydrate post-exercise is important, the type of carbohydrate source might also be important, particularly if a second training session or event will occur less than 8 hours later.

In these situations, athletes should choose carbohydrate sources with a high GI for example white bread, white rice, white potatoes in the first half hour or so after exercise.

This should be continued until the normal meal pattern resumes. Since most athletes develop a fluid deficit during exercise, replenishment of fluids post-exercise is also a very important consideration for optimal recovery. It is recommended that athletes consume 1. Protein is an important part of a training diet and plays a key role in post-exercise recovery and repair.

Protein needs are generally met and often exceeded by most athletes who consume sufficient energy in their diet. The amount of protein recommended for sporting people is only slightly higher than that recommended for the general public.

For athletes interested in increasing lean mass or muscle protein synthesis, consumption of a high-quality protein source such as whey protein or milk containing around 20 to 25 g protein in close proximity to exercise for example, within the period immediately to 2 hours after exercise may be beneficial.

As a general approach to achieving optimal protein intakes, it is suggested to space out protein intake fairly evenly over the course of a day, for instance around 25 to 30 g protein every 3 to 5 hours, including as part of regular meals.

There is currently a lack of evidence to show that protein supplements directly improve athletic performance. Therefore, for most athletes, additional protein supplements are unlikely to improve sport performance. A well-planned diet will meet your vitamin and mineral needs.

Supplements will only be of any benefit if your diet is inadequate or you have a diagnosed deficiency, such as an iron or calcium deficiency. There is no evidence that extra doses of vitamins improve sporting performance.

Nutritional supplements can be found in pill, tablet, capsule, powder or liquid form, and cover a broad range of products including:. Before using supplements, you should consider what else you can do to improve your sporting performance — diet, training and lifestyle changes are all more proven and cost effective ways to improve your performance.

Relatively few supplements that claim performance benefits are supported by sound scientific evidence. Use of vitamin and mineral supplements is also potentially dangerous.

Journal of the Endurance nutrition for performance enhancement Society Eneurance Sports Nutrition Antioxidant properties of Polyphenols 17Article number: 33 Ednurance this perfornance. Metrics prrformance. The ketogenic diet has become popular among First aid for DKA athletes as a performance enhancer. PubMed and Web of Science searches were conducted through November Articles were excluded if they were not a primary source or hypotheses were not tested with endurance athletes i. Two of five trials reported significant increases in VO 2 max across all diets; while three trials and one case study reported no significant VO 2 max findings.

Endurance nutrition for performance enhancement -

VO 2 max is considered the gold standard for measuring aerobic fitness. Higher levels of VO 2 max indicate greater endurance capacity.

It is important to note that while VO 2 max is an established measure of endurance capacity, relative VO 2 max is confounded by changes in body weight and thus not without limitations.

For this reason, secondary performance outcomes i. Specifically, this review focuses on peer-reviewed articles examining endurance athletes e. The included studies looked at a variety of outcomes; however, the primary outcome of interest to this review is VO 2 max. Articles were identified for inclusion via electronic database literature searches.

An initial search was conducted using Web of Science and PubMed, on February 1, Subsequent searches of Web of Science and PubMed were conducted, using identical search criteria, in order to capture the most recent publications available. The final search was conducted on November 17, The following key terms were used to search the databases for articles by topic: ketogenic, race, walker, cyclist, runner, marathon, endurance, and athlete.

Asterisks denote truncation. Articles that met inclusion criteria from each database were compiled using Endnote software. Duplicates were removed, and abstracts were pre-screened for source type. Articles were excluded if they were not a primary source.

After identifying all eligible records, a data matrix was developed and data were extracted on the following variables: study design, athlete type i. Data from the matrix are presented in Tables 1 and 2.

Results were synthesized qualitatively. Figure 1 illustrates the screening process and articles included in this review. After removing duplicates and pre-screening, 28 articles remained.

After further review, 21 additional records were excluded see Fig. All exclusions were conducted to emphasize the effect of ketogenic diet consumption on sport-specific performance in endurance athletes. See Fig. Arrows pointing right indicate the number of articles excluded and for what reason.

Among the seven studies included in this review, sex and athlete type were inextricable variables. Five of seven studies examined VO 2 max outcomes in only male athletes [ 12 , 13 , 14 , 15 , 16 ]. However, among those studies, athlete type varied: one study recruited male runners [ 13 ], one recruited male race walkers [ 12 ], one recruited male cyclists [ 15 ], and two recruited a mixed sample of male endurance athletes [ 14 , 16 ].

Two of the seven studies recruited both male and female athletes; one recruited a sample of race walkers [ 7 ] and the other recruited a sample of mixed endurance athletes [ 17 ].

Of the six trial studies, all included a standard, high carbohydrate comparison diet [ 7 , 12 , 13 , 14 , 15 , 16 ], while the case study provided no comparison diet [ 17 ]. Studies either provided participants with meals [ 7 , 12 , 15 ] or with dietary guidance, including sample meal plans [ 13 , 14 , 16 , 17 ].

Adherence to diet was tracked via objective researcher observation and measurement [ 7 , 12 , 15 ] or participant self-report e. All studies explicitly reported tracking serum ketone levels as a biomarker for ketosis. All studies lasted between three and 12 weeks. In a three-week nonrandomized trial, Carr et al.

reported significant increases in VO 2 max from baseline for all diet types EAKD: Using a similar design, Burke et al. found a significant increase in VO 2 max for all athletes EAKD: McSwiney et al. showed a 3. This was a smaller increase than the 4. Shaw et al.

Using a pre-posttest design, Phinney et al. found no difference in VO 2 max between a high carbohydrate comparison diet and EAKD pre-intervention HCD: 5.

Heatherly et al. Instead, this study reported on the percent of baseline pre-dietary intervention VO 2 max achieved at various race paces tested post-EAKD consumption.

Finally, Zinn et al. Zinn et al. was a case study with no reference comparison diet. Of three studies that reported TTE, Shaw et al. and Phinney et al. each found no significant difference in TTE by diet type [ 15 , 16 ], while Zinn et al.

Differences in race times by dietary intervention were reported by three studies [ 12 , 13 , 14 ] and found to be significant in one [ 12 ].

Specifically, Burke et al. RPE was measured in three studies [ 12 , 13 , 16 ] and found to be significantly different from baseline in one [ 12 ]. Burke et al. Finally, peak power was measured in two studies [ 14 , 17 ]. McSwinney et al. reported that post-intervention peak power was significantly different between diets, with EAKD athletes improving their peak power and comparison diet athletes decreasing their peak power EAKD: 8.

See Table 2 for a full list of results. It has been hypothesized that consuming a ketogenic diet may enhance performance among endurance athletes by promoting a shift in substrate utilization that enhances physiological training benefits [ 3 , 18 ].

The present review explores this hypothesis by examining associations between EAKD consumption and VO 2 max, a biomarker for endurance capacity [ 11 ]. Two of the seven studies included in this review found a significant increase in VO 2 max post-EAKD consumption [ 7 , 12 ]. However, both articles reported significant VO 2 max increases across all diets, and that outcomes were independent of dietary intervention.

Interestingly, both studies were conducted among elite race walkers that self-selected their dietary intervention, and the athletes that self-selected into the EAKD had slightly higher average baseline and post-treatment VO 2 max values [ 7 , 12 ].

Furthermore, Burke et al. A review conducted by Williams et al. revealed the potential for 97 genes to predict VO 2 max trainability, suggesting that genetics may account for differing training outcomes among athletes [ 20 ].

Certain dietary preferences, which both acutely and chronically influence substrate utilization, have also been linked to gene variations, highlighting the possibility for both dietary choices and training outcomes to be mediated by genetics [ 19 , 21 ].

Randomized controlled trials and genome-wide association studies can be leveraged to control for, and explore the impact of, such factors in future studies of the EAKD.

Four of the seven studies reviewed reported non-significant VO 2 max outcomes [ 14 , 15 , 16 , 17 ]. In a non-randomized trial, McSwiney et al. reported a VO 2 max increase in both groups of male endurance athletes post-EAKD EAKD: In a pre-posttest design, Phinney et al.

reported a non-significant decrease in VO 2 max from baseline among five elite male cyclists pre- vs. post-EAKD: 5. In a case study, Zinn et al. Finally, in a randomized crossover study, Shaw et al. reported no significant changes from baseline did not report VO 2 max outcomes, instead providing the percentage of baseline VO 2 max achieved at various race paces i.

This is corroborated by some of the secondary outcomes reported in Table 2 , including reports of EAKD being associated with significantly higher RPE [ 12 ], and decreased TTE [ 17 ]. Only one study reported significant positive secondary findings: a higher peak power in athletes post-EAKD compared to the standard, high carbohydrate diet [ 14 ].

Despite the popularity of the diet as an ergogenic aid, this review provides evidence that EAKD consumption produces mixed results, in terms of endurance performance, when compared to a high carbohydrate diet. For example, the EAKD significantly increases fat oxidation, requiring greater oxygen consumption due to the increased oxygen demands during fatty acid metabolism versus carbohydrate metabolism [ 12 , 22 ].

This increased demand for oxygen reduces the beneficial impact of an increased VO 2 max because a greater percentage of maximal oxygen uptake is now required to maintain any given race pace [ 13 ]. Second, EAKD metabolites such as tryptophan and ammonia may promote fatigue by influencing the central nervous system [ 23 , 24 ].

Finally, it has been shown that the EAKD leads to increased satiety and reduced energy intake [ 25 ]. Reduced energy intake, and the accompanying weight loss, may be beneficial for some individuals but could also present a sustainability issue for highly active athletes.

Substantial reductions in body weight may negatively impact mental, hormonal, and bone health, as well as recovery time and general exercise performance [ 26 , 27 ].

Illustrating these mechanisms, Heatherly et al. In multiple studies, participant self-reports e. This could be a combined result of the alterations in fuel economy, metabolism, and energy intake described above, though not all athletes reported experiencing negative side effects.

Both studies exhibiting a statistically significant increase in VO 2 max examined the effects of EAKD consumption in professional race walkers with high base levels of aerobic capacity, a factor that has been associated with faster recovery times and greater positive adaptations to training [ 29 , 30 , 31 ].

However, based on previous evidence, it is reasonable to hypothesize that these protocol differences may have contributed to the diverse outcomes reported [ 6 , 28 , 32 ]. In examining the results, it is important to bear in mind that this review consists of just seven studies, only one of which was randomized [ 16 ].

Carr et al. were all prospective trials, however they allowed participants to choose their dietary intervention [ 7 , 12 , 14 ].

Although this self-selection method generally improves rates of adherence to the diets, it also introduces risk of bias in that those athletes who chose the EAKD may have other lifestyle or dietary tendencies that could affect their biological response to the diet. were pre-posttest studies, which are subject to threats to internal validity, such as the fact that passage of time results in natural decreases in VO 2 max [ 13 , 15 ].

was a case study [ 17 ]. Although the article provides a wealth of hypothesis generating observations, without a comparison group we cannot conclude whether the EAKD was more or less effective than the standard, high carbohydrate diet for athletes.

All studies had relatively small sample sizes, which reduced the statistical power of the analyses. It is possible that, with a larger sample size, the seven studies might have exhibited corroboratory results.

The small sample sizes also exacerbated the problem of drop-out rates, which were considerable in one of the five studies. At the review level, heterogeneity in dietary interventions, adherence measurements, VO 2 max testing procedures, training protocols, and athlete types all introduced variation that made comparisons across studies difficult.

For example, four studies measured VO 2 max using a treadmill test [ 7 , 12 , 13 , 16 ], while the other three studies used a cycle ergometer [ 14 , 15 , 17 ]. Previous reviews suggest that these two testing procedures produce inconsistent results, with higher VO 2 max outcomes reported for treadmill as compared to cycle ergometer tests [ 33 ].

Therefore, inter-article comparisons of the change in VO 2 max by diet from baseline may be more reliable than inter-article comparisons of the absolute outcome values reported.

Furthermore, research suggests that VO 2 max may be an inaccurate predictor of endurance performance in runners, specifically due to variations in running economy and fatigue [ 34 , 35 ].

Therefore, VO 2 max may not be a strong indicator of endurance capacity in some sports, further complicating this measure as a comparison across heterogeneous groups of athletes. In addition to VO 2 max outcomes, Table 2 provides a matrix of secondary outcomes i.

For example, although all three diet groups in the study by Burke et al. experienced a significant increase in VO 2 max from baseline, only the comparison groups i. Furthermore, the EAKD group reported significantly higher RPE values compared to baseline during a graded economy test.

Future research in this field can benefit from utilizing a variety of performance metrics, such as the ones discussed in this review, to triangulate overall effects of diet on athletic performance, limiting biases introduced from relying on one marker alone.

Additionally, as this research area develops, it may be prudent to conduct reviews among athletes of a single type e. Because only two databases were used to identify articles for review, it is possible that other studies of EAKD and endurance performance do exist in the literature.

However, exploratory investigations of other databases retrieved no additional articles that met inclusion criteria. It is noteworthy that six of seven studies included in this review were published within the last 5 years, suggesting that scientific attention to this topic is fairly recent.

Due to the contemporary nature of the research question, it is also possible that yet-to-be-published research exists on this topic. Therefore, future reviews may eventually produce more conclusive evidence. Finally, the potential risk of reporting bias is always present. Unfortunately, it is difficult to assess publication bias because we cannot know the extent of the evidence that has gone unpublished.

However, due to the controversial nature of this topic among scientists and lay people alike, it seems likely that both significant and null findings would be publishable. Despite popular interest in the ketogenic diet as an ergogenic aid in endurance sport, there are few published studies examining the effect of EAKD consumption on VO 2 max and other outcomes i.

When compared to a high carbohydrate diet, there are mixed findings for the effect of EAKD consumption on endurance performance. The limited number of published studies point to a need for more research in this field. Specifically, randomized studies performed in mixed sex samples are needed.

Researchers might also consider examining EAKD-like diets that do not induce ketosis. Burke, L. J Physiol, Carr, A. Nutrients, Heatherly, A. Med Sci Sports Exerc, McSwiney, F.

When dehydration occurs, plasma volume decreases in proportion to the decrease in total body water. As a result of the lower plasma volume, cardiac filling and stroke volume declines, leading to increased heart rate and increased perceived exertion during aerobic exercise Montain et al.

redistribution of blood flow from the central to peripheral circulation is required for heat dissipation. Thus, when heat stress is combined with dehydration there is greater cardiovascular strain resulting from the competition between the central and peripheral circulation for limited blood volume Nadel, As determined in a series of carefully conducted studies by the U.

These studies determined that, starting at a skin temperature of ~27 to 29°C, the percentage decrement in aerobic time trial performance declines linearly by ~1.

In short, hyperthermia particularly hot skin exacerbates the performance decrement for a given level of dehydration. Accordingly, athletes should consider the environmental conditions as well as individual sweating rate when developing hydration strategies for training and competition Kenefick et al.

Skin temperature increases in proportion to ambient temperature and humidity and is modified by convective cooling from air movement and the cooling effect of sweat evaporation during exercise. More detailed discussions on this topic can be found elsewhere Sawka et al.

In the absence of such planning, concrete advice on fluid intake needs is difficult to give as differences between individuals, race distances, course profiles, and environmental conditions will confound any suggestions. Another possible hydration strategy is for athletes to simply drink according to thirst sensation i.

ad libitum fluid intake. This strategy has been advocated by some based on 1 recent studies reporting no time-trial performance enhancement from ingesting fluid at a rate above that of ad libitum intake Goulet, ; Dion et al.

However, more work is needed to determine the efficacy of this strategy as there are several potential limitations to consider. Thirst perception is complex and ad libitum fluid intake is dictated by a number of regulatory and non-regulatory factors. The stimulation of physiological thirst does not occur until after dehydration has accrued.

The reader is referred to our recent review Baker et al. The rate of fluid absorption is closely related to the carbohydrate content of the drink with high-carbohydrate concentrations compromising fluid delivery, although multiple transportable carbohydrates can remove some of this impaired fluid delivery.

Enhancment are the basic components of First aid for DKA food we eat. These are carbohydrates, Endutance, and fat. Eating macros in proper ratios fuel your endurance. Healthy adult eating includes ratios of:.

Adjust these ratios based on the goal of the physical activity. For example, an endurance athlete would increase their carb enhancenent to improve muscle glycogen stores.

A strength Hypoglycemic unawareness management techniques would First aid for DKA a higher protein intake. This would better support Essential oils for pain relief more muscle mass.

Carbs come in different forms. Two to know are Pre-match meal ideas and perfor,ance carbs. Simple carbs Endurance nutrition for performance enhancement, also known as simple sugars, have snhancement to nutritiln sugar molecules.

Endurance nutrition for performance enhancement include glucose, dextrose, or fructose. Simple carbs break down quickly in the body. Foods Endurance nutrition for performance enhancement Endurancr sugars include fruits, milk, vegetables, table pefformance, candy, and soft drinks.

They nutritipn energy but lack fiber, vitamins, and other Polyphenols and liver health nutrients. Complex carbs have three or more sugar molecules.

You'll find these in foods like beans, whole grains, whole-wheat pasta, potatoes, corn, and legumes. So, which kind of carbohydrate should you consume? Most carbs should come from complex sources and naturally occurring sugars.

Processed carbs and refined sugars should be limited or avoided. How many carbs should endurance athletes eat? There will be some differences based on the type and duration of training. This helps support the high volume of glucose needed for that level of physical activity.

Each carb has 4 calories per gram. Endurance athletes should eat 8 to 10 grams of carbohydrate per kilogram kg of body weight per day. This will depend on the duration of their endurance event. For endurance training lasting 4 to 5 hours, endurance athletes should consume 10 grams per kilogram of body weight.

For example, an endurance runner who weighs 70 kg and competes in an endurance event lasting 4 hours or more should consume a minimum of grams of carbohydrate daily. In comparison, a power athlete would consume fewer carbs around 4 to 5 grams per kilogram of body weight. A power athlete's focus would be more so to increase protein intake.

Many people focus only on carbs for endurance exercise. However, protein intake for endurance athletes is equally important. The purpose of protein is to build and replenish lean muscle tissue.

Protein also acts as a source of energy in times of caloric deficits. Animal-based protein, as the name implies, is protein that comes from animals. This type of protein is considered a complete protein. It is complete because it contains all nine essential amino acids.

Animal-based protein sources include:. Plant-based protein is protein that comes from plants. Plant-based protein is considered an incomplete protein. This isn't to say it is bad, it just doesn't have all essential amino acids.

Plant-based protein sources include:. Protein has 4 calories per gram. How much protein do you need to eat? Protein intake for a normal healthy adult is around 0. Endurance athletes should eat protein at 1. Athletes taking part in longer endurance events need more protein than those running shorter distances.

For example, endurance athletes weighing 70 kg would need to consume 98 grams of protein daily to support their endurance exercise. Athletes who take part in strength or power sports will consume up to 2. Endurance athletes on a plant-based diet will have an increased protein requirement.

This is due to a plant-based diet consisting of incomplete proteins. Endurance athletes need healthy fats in their diet. Supply two fatty acids the body can't manufacture linoleic acid and linolenic acid.

There are many types of fat, some good and some not. The most significant types are triglycerides, fatty acids, phospholipids, and cholesterol.

Of these, triglycerides are most commonly found in food. Fatty acids break down further into saturated, monounsaturated, and polyunsaturated fats. Endurance athletes need to minimize the amount of saturated fat consumed. Most fat calories should be in the form of monounsaturated fatty acids.

When adding fat to your diet to keep up with the demands of endurance training, focus your fat intake on healthy fats 1.

This includes:. In addition to the three macros, endurance athletes also benefit from some specific micronutrients. Two to consider are vitamins C and D.

Vitamin C is perhaps best known for boosting immunity. But it also serves other important purposes. One is that it is an antioxidant, protecting the cells against free radical damage. Another is that it supports wound healing.

According to a studyvitamin C also helps athletes recover during the competitive season 2. Citrus fruits and potatoes are high in vitamin C.

So are peppers, broccoli, strawberries, and kiwi. Vitamin D is important for bone health. Weak bones mean more fractures and breaks. A study also ties adequate vitamin D levels with improved athletic performance 3. Taking a cod liver oil supplement is one way to get more of this nutrient.

Orange juice and dairy are also high in vitamin D. We lose water throughout the day. It escapes our body through normal respiration, sweating, and urinary output. When we exercise, we lose more. Staying hydrated is more than about satisfying thirst.

The top reasons for proper hydration, which are especially important for clients taking on endurance events, include:. Endurance athletes need to watch their hydration throughout the day, especially during workouts.

Water intake guidelines are provided by the National Academies of Sciences, Engineering, and Medicine 4.

: Endurance nutrition for performance enhancement

Nutrition and athletic performance: MedlinePlus Medical Encyclopedia	J Am Diet Assoc ; In contrast to dietary fat, body fat stores are of tremendous importance during physical activity, as long as the intensity is not too high and there is adequate O2 delivery to use fat as a fuel source. However, the specific percent contribution of protein to total daily intake for endurance athletes has been in question for some time. They should consider their calorie and macronutrient needs and ensure they eat a varied diet that provides essential vitamins and minerals. Athletes doing intense training may benefit from ingesting more than two times the recommended daily amount RDA of protein in their diet.
Latest news	Roberts, M. They supply energy but lack fiber, vitamins, and other key nutrients. This is corroborated by some of the secondary outcomes reported in Table 2 , including reports of EAKD being associated with significantly higher RPE [ 12 ], and decreased TTE [ 17 ]. International Journal of Sport Nutrition and Exercise Metabolism , 28 5 , — There is little evidence to support the efficacy or safety of many dietary supplements, including:. In the absence of such planning, concrete advice on fluid intake needs is difficult to give as differences between individuals, race distances, course profiles, and environmental conditions will confound any suggestions.

Nutrition and Performance in Sport Science at the Tip of the Fork Christophe Hausswirth ed. You can satisfy this need by having:. After exercise, you need to eat carbohydrates to rebuild the stores of energy in your muscles if you are working out heavily. Protein is important for muscle growth and to repair body tissues. Protein can also be used by the body for energy, but only after carbohydrate stores have been used up. Most Americans already eat almost twice as much protein as they need for muscle development. Too much protein in the diet:. Often, people who focus on eating extra protein may not get enough carbohydrates, which are the most important source of energy during exercise. Water is the most important, yet overlooked, nutrient for athletes. Water and fluids are essential to keep the body hydrated and at the right temperature. Your body can lose several liters of sweat in an hour of vigorous exercise. Clear urine is a good sign that you have fully rehydrated. Some ideas for keeping enough fluids in the body include:. Offer children water often during sports activities. They do not respond to thirst as well as adults. Teenagers and adults should replace any body weight lost during exercise with an equal amount of fluids. For every pound grams you lose while exercising, you should drink 16 to 24 ounces to milliliters or 3 cups milliliters of fluid within the next 6 hours. Changing your body weight to improve performance must be done safely, or it may do more harm than good. Keeping your body weight too low, losing weight too quickly, or preventing weight gain in an unnatural way can have negative health effects. It is important to set realistic body weight goals. Young athletes who are trying to lose weight should work with a registered dietitian. Experimenting with diets on your own can lead to poor eating habits with inadequate or excessive intake of certain nutrients. Speak with a health care professional to discuss a diet that is right for your sport, age, sex, and amount of training. Buschmann JL, Buell J. Sports nutrition. In: Miller MD, Thompson SR. Philadelphia, PA: Elsevier; chap Riley E, Moriarty A. In: Madden CC, Putukian M, Eric C. McCarty EC, Craig C. Young CC, eds. 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. Fibrous carbohydrates can be beneficial as these tend to cause GI disturbances. UW School of Medicine and Public Health. Refer a Patient. Clinical Trials. Find a Doctor. Search Submit. Pay a bill.
