Further, the rate of absorption may lead to a more favorable anabolic hormonal environment [ , , ]. Calbet et al. Each of the nitrogen containing solutions contained 15 g of glucose and 30 g of protein.

Results indicated that peptide hydrolysates produced a faster increase in venous plasma amino acids compared to milk proteins. Further, the peptide hydrolysates produced peak plasma insulin levels that were two- and four-times greater than that evoked by the milk and glucose solutions, respectively, with a correlation of 0.

In a more appropriate comparison, Morifuji et al. However, Calbet et al. The hydrolyzed casein, however, did result in a greater amino acid response than the nonhydrolyzed casein. Finally, both hydrolyzed groups resulted in greater gastric secretions, as well as greater plasma increases, in glucose-dependent insulinotropic polypeptides [ ].

Buckley and colleagues [ ] found that a ~ 30 g dose of a hydrolyzed whey protein isolate resulted in a more rapid recovery of muscle force-generating capacity following eccentric exercise, compared with a flavored water placebo or a non-hydrolyzed form of the same whey protein isolate.

In agreement with these findings, Cooke et al. Three and seven days after completing the damaging exercise bout, maximal strength levels were higher in the hydrolyzed whey protein group compared to carbohydrate supplementation.

Additionally, blood concentrations of muscle damage markers tended to be lower when four ~g doses of a hydrolyzed whey protein isolate were ingested for two weeks following the damaging bout.

Beyond influencing strength recovery after damaging exercise, other benefits of hydrolyzed proteins have been suggested. For example, Morifuji et al. Furthermore, Lockwood et al.

Results indicated that strength and lean body mass LBM increased equally in all groups. However, fat mass decreased only in the hydrolyzed whey protein group.

While more work needs to be completed to fully determine the potential impact of hydrolyzed proteins on strength and body composition changes, this initial study suggests that hydrolyzed whey may be efficacious for decreasing body fat.

Finally, Saunders et al. The authors reported that co-ingestion of a carbohydrate and protein hydrolysate improved time-trial performance late in the exercise protocol and significantly reduced soreness and markers of muscle damage. Two excellent reviews on the topic of hydrolyzed proteins and their impact on performance and recovery have been published by Van Loon et al.

The prevalence of digestive enzymes in sports nutrition products has increased during recent years with many products now containing a combination of proteases and lipases, with the addition of carbohydrates in plant proteins.

Proteases can hydrolyze proteins into various peptide configurations and potentially single amino acids. It appears that digestive enzyme capabilities and production decrease with age [ ], thus increasing the difficulty with which the body can break down and digest large meals.

Digestive enzymes could potentially work to promote optimal digestion by allowing up-regulation of various metabolic enzymes that may be needed to allow for efficient bodily operation. Further, digestive enzymes have been shown to minimize quality differences between varying protein sources [ ].

Individuals looking to increase plasma peak amino acid concentrations may benefit from hydrolyzed protein sources or protein supplemented with digestive enzymes.

However, more work is needed before definitive conclusions can be drawn regarding the efficacy of digestive enzymes. Despite a plethora of studies demonstrating safety, much concern still exists surrounding the clinical implications of consuming increased amounts of protein, particularly on renal and hepatic health.

The majority of these concerns stem from renal failure patients and educational dogma that has not been rewritten as evidence mounts to the contrary. Certainly, it is clear that people in renal failure benefit from protein-restricted diets [ ], but extending this pathophysiology to otherwise healthy exercise-trained individuals who are not clinically compromised is inappropriate.

Published reviews on this topic consistently report that an increased intake of protein by competitive athletes and active individuals provides no indication of hepato-renal harm or damage [ , ]. This is supported by a recent commentary [ ] which referenced recent reports from the World Health Organization [ ] where they indicated a lack of evidence linking a high protein diet to renal disease.

Likewise, the panel charged with establishing reference nutrient values for Australia and New Zealand also stated there was no published evidence that elevated intakes of protein exerted any negative impact on kidney function in athletes or in general [ ].

Recently, Antonio and colleagues published a series of original investigations that prescribed extremely high amounts of protein ~3. The first study in had resistance-trained individuals consume an extremely high protein diet 4.

A follow-up investigation [ ] required participants to ingest up to 3. Their next study employed a crossover study design in twelve healthy resistance-trained men in which each participant was tested before and after for body composition as well as blood-markers of health and performance [ ].

In one eight-week block, participants followed their normal habitual diet 2. No changes in body composition were reported, and importantly, no clinical side effects were observed throughout the study. Finally, the same group of authors published a one-year crossover study [ ] in fourteen healthy resistance-trained men.

This investigation showed that the chronic consumption of a high protein diet i. Furthermore, there were no alterations in clinical markers of metabolism and blood lipids. Multiple review articles indicate that no controlled scientific evidence exists indicating that increased intakes of protein pose any health risks in healthy, exercising individuals.

A series of controlled investigations spanning up to one year in duration utilizing protein intakes of up to 2. In alignment with our previous position stand, it is the position of the International Society of Sports Nutrition that the majority of exercising individuals should consume at minimum approximately 1.

The amount is dependent upon the mode and intensity of the exercise, the quality of the protein ingested, as well as the energy and carbohydrate status of the individual. Concerns that protein intake within this range is unhealthy are unfounded in healthy, exercising individuals.

An attempt should be made to consume whole foods that contain high-quality e. The timing of protein intake in the period encompassing the exercise session may offer several benefits including improved recovery and greater gains in lean body mass.

In addition, consuming protein pre-sleep has been shown to increase overnight MPS and next-morning metabolism acutely along with improvements in muscle size and strength over 12 weeks of resistance training.

Intact protein supplements, EAAs and leucine have been shown to be beneficial for the exercising individual by increasing the rates of MPS, decreasing muscle protein degradation, and possibly aiding in recovery from exercise. In summary, increasing protein intake using whole foods as well as high-quality supplemental protein sources can improve the adaptive response to training.

The most recent recommendations for athletes from the American College of Sports Medicine ACSM also focus on protein timing, not just total intake, ensuring high quality protein is consumed throughout the day after key exercise sessions and around every 3—5 hours over multiple meals, depending on requirements.

In athletes that are in energy deficit, such as team sport players trying to lose weight gained in the off season, there may be a benefit in consuming protein amounts at the high end, or slightly higher, than the recommendations, to reduce the loss of muscle mass during weight loss.

Timing of protein consumption is important in the recovery period after training for athletes. Between 30 minutes and 2 hours after training, it is recommended to consume g of protein alongside some carbohydrate.

A whey protein shake contains around 20g of protein, which you can get from half a chicken breast or a small can of tuna. For more information on protein supplements, see the supplements section. To date, there is no clear evidence to suggest that vegetarian or vegan diets impact performance differently to a mixed diet, although it is important to recognise that whatever the dietary pattern chosen, it is important to follow a diet that is balanced to meet nutrient requirements.

More research is needed, to determine whether vegetarian or vegan diets can help athletic performance. More plant-based diets can provide a wide variety of nutrients and natural phytochemicals, plenty of fibre and tend to be low in saturated fat, salt and sugar.

Fat is essential for the body in small amounts, but it is also high in calories. The type of fat consumed is also important. Studies have shown that replacing saturated fat with unsaturated fat in the diet can reduce blood cholesterol, which can lower the risk of heart disease and stroke.

Fat-rich foods usually contain a mixture of saturated and unsaturated fatty acids but choosing foods that contain higher amounts of unsaturated fat and less saturated fat, is preferable as most of us eat too much saturated fat.

Find more information on fat on our pages on this nutrient. If I am doing endurance training, should I be following low carbohydrate, high fat diets? Carbohydrate is important as an energy source during exercise.

Having very low intakes of carbohydrate when exercising can cause low energy levels, loss of concentration, dizziness or irritability. Because carbohydrate is important for providing energy during exercise, there is a benefit in ensuring enough is consumed.

This is especially for high-intensity exercise where some studies have shown that performance is reduced when carbohydrate intakes are low. Some studies in specific exercise scenarios such as lower intensity training in endurance runners, have found beneficial effects of low carbohydrate diets on performance.

However, these results have not been consistent and so at the moment we do not have enough evidence to show that low-carbohydrate diets can benefit athletic performance. Water is essential for life and hydration is important for health, especially in athletes and those who are physically active, who will likely have higher requirements.

Drinking enough fluid is essential for maximising exercise performance and ensuring optimum recovery. Exercising raises body temperature and so the body tries to cool down by sweating. This causes the loss of water and salts through the skin.

Generally, the more a person sweats, the more they will need to drink. Average sweat rates are estimated to be between 0. Dehydration can cause tiredness and affect performance by reducing strength and aerobic capacity especially when exercising for longer periods.

So, especially when exercising at higher levels or in warmer conditions, it is important to try and stay hydrated before, during and after exercise to prevent dehydration. In most cases, unless training at a high intensity for over an hour, water is the best choice as it hydrates without providing excess calories or the sugars and acids found in some soft drinks that can damage teeth.

For more information on healthy hydration see our pages on this topic. For those who are recreationally active to a high level, or for athletes, managing hydration around training or competition is more important.

The higher intensity and longer duration of activity means that sweat rates tend to be higher. Again, the advice for this group would be to ensure they drinks fluids before, during and after exercise. Rehydration would usually involve trying to drink around 1. Below are some examples of other drinks, other than water that may be used by athletes, both recreational and elite.

Sports drinks can be expensive compared to other drinks; however it is easy to make them yourself! To make your own isotonic sports drink, mix ml fruit squash containing sugar rather than sweeteners , ml water and a pinch of salt. Supplements are one of the most discussed aspects of nutrition for those who are physically active.

However, whilst many athletes do supplement their diet, supplements are only a small part of a nutrition programme for training. For most people who are active, a balanced diet can provide all the energy and nutrients the body needs without the need for supplements. Sports supplements can include micronutrients, macronutrients or other substances that may have been associated with a performance benefit, such as creatine, sodium bicarbonate or nitrate.

The main reasons people take supplements are to correct or prevent nutrient deficiencies that may impair health or performance; for convenient energy and nutrient intake around an exercise session; or to achieve a direct performance benefit. Whilst adequate amounts of protein and carbohydrate are both essential in maximising performance and promoting recovery, most people should be able to get all the nutrients they need by eating a healthy, varied diet and, therefore, supplements are generally unnecessary.

For athletes, supplementing the diet may be beneficial, possibly on performance, on general health or for reducing injury and illness risk. However, there is not much research on many of the commonly used supplements, and there are only a small number of supplements where there is good evidence for a direct benefit on performance, including caffeine, creatine in the form of creatine monohydrate , nitrate and sodium bicarbonate.

Even in these cases, the benefits on performance vary greatly depending on the individual and there is only evidence for a benefit in specific scenarios. This means that any athletes considering supplementation will need to weigh the potential benefits with the possible negative impacts, such as negative effects on general health or performance, risk of accidental doping or risks of consuming toxic levels of substances such as caffeine.

The advice to consider supplementation for a performance benefit is for high performance athletes and should be carried out alongside expert advice from qualified sports nutritionists or dietitians. It is a common myth that consuming lots of excess protein gives people bigger muscles.

Quite often, people taking part in exercise focus on eating lots of protein, and consequently may not get enough carbohydrate, which is the most important source of energy for exercise.

The main role of protein in the body is for growth, repair and maintenance of body cells and tissues, such as muscle. Fifteen to 25g of high-quality protein has been shown to be enough for optimum muscle protein synthesis following any exercise or training session, for most people, and any excess protein that is ingested will be used for energy.

The recommendations for daily protein intake are set equally for both endurance training and resistance training athletes, so higher intakes are not recommended even for those exclusively trying to build muscle.

Any more protein than this will not be used for muscle building and just used as energy. If you plan on training or exercising twice in one day or on back-to-back days, try to eat this carbohydrate-rich meal or snack within 30 minutes of finishing your session.

There are many dietitians that specialize in sports nutrition. They can work with you to set personalized targets for carbohydrate, fat and protein intake before, during and after training or playing your sport.

They will consider various factors such as, the intensity and duration of your exercise, your training goals, your culture and preferences and medical history when making recommendations.

Sports Nutrition: Diet and Nutritional Supplements

Sports nutrition guidelines -

For professional athletes, getting personalised nutrition advice from a qualified sports nutritionist or dietitian is likely to be an important part of their training support. Doing physical activity will increase your energy expenditure the calories you use , as energy is required during exercise to fuel the contracting muscles, increased breathing and heart rate and metabolism.

It is difficult to lose weight just by getting more active and it is still important to control your calorie intake for weight control. The most effective weight loss programmes include both a controlled diet and increased physical activity. It is also important to be active to keep weight off after weight loss.

A study of people in the US who have successfully maintained their weight loss shows that they tend to be active for about an hour a day usually walking and spend less time in sedentary activities like watching TV in their free time.

The benefits of physical activity go beyond just burning off calories and can help preserve muscle as you lose weight and increase the proportion of muscle in the body. We also know that physical activity, and spending less time sitting, can reduce your risk of developing several chronic diseases, such as heart disease.

The main role of carbohydrates in physical activity is to provide energy. For athletes, if their diet does not contain enough carbohydrate, it is likely that their performance and recovery will be impaired, as carbohydrate is the key fuel for the brain and for muscles during exercise.

The body can store carbohydrates in the muscles and liver as glycogen and use these stores as a source of fuel for physical activity. These glycogen stores are limited, so for those training at a high level, it is important to be fully fuelled at the start of any exercise.

Glycogen is the main source of energy at the start of exercise and during short bursts of exercise. If you are doing high intensity training for long periods and your glycogen stores are not sufficient you may feel tired, lack energy and not be able to perform at your best. So, regular intake of carbohydrate-rich foods can be important in this case to keep stores topped up.

The correct food choices can help ensure the body has enough energy for activity, as well as help aid recovery. Starchy foods are an important source of carbohydrates in our diet.

Wholegrain varieties also provide fibre, and a range of vitamins and minerals including B vitamins, iron, calcium and folate. Find out more about this topic on our pages on starchy foods, sugar and fibre. The amount of carbohydrate you need will depend on the frequency, type, duration and intensity of physical activity you do.

Competitive sports people and athletes will likely require more carbohydrates than an average gym user to match the intensity of their activity level. If you are active at around the current recommended levels minutes of moderate activity or 75 minutes of high intensity activity plus two sessions of muscle strengthening activities per week , then you can follow general healthy eating guidance to base meals on starchy carbohydrates, choosing wholegrain and higher fibre options where possible.

For information about portion sizes of starchy foods you can use our Get portion wise! portion size guide. At this level of activity, it is unlikely you will need to consume extra carbohydrates by eating more or by using products like sports drinks or other carbohydrate supplements, and these can be counterproductive if you are trying to control your weight as they will contribute extra calories.

Sports drinks also contain sugars, which can damage teeth. Regardless of your level of activity, you should try not to meet your requirements by packing your entire carbohydrate intake into one meal.

Spread out your intake over breakfast, lunch, dinner and snacks that fit around planned exercise. For athletes and individuals who are recreationally active to a higher level such as training for a marathon , consuming additional carbohydrate may be beneficial for performance.

Athletes can benefit from having some carbohydrate both before and after exercise to ensure adequate carbohydrate at the start of training and to replenish glycogen stores post exercise. In longer duration, high intensity exercise minutes or more , such as a football match or a marathon, consuming some carbohydrate during exercise can also improve performance, for example in the form of a sports drink.

Estimated carbohydrate needs are outlined below and depend on the intensity and duration of the exercise sessions International Olympics Committee :. For example, from this guidance, someone who weighs 70kg doing light activity would need g carbohydrate per day whereas if they were training at moderate to high intensity for 2 hours a day, they would need g carbohydrate per day.

Protein is important in sports performance as it can boost glycogen storage, reduce muscle soreness and promote muscle repair. For those who are active regularly, there may be benefit from consuming a portion of protein at each mealtime and spreading protein intake out throughout the day.

As some high protein foods can also be high in saturated fat, for example fatty meats or higher fat dairy products, it is important to choose lower fat options, such as lean meats.

Most vegans get enough protein from their diets, but it is important to consume a variety of plant proteins to ensure enough essential amino acids are included. This is known as the complementary action of proteins. More information on vegetarian and vegan diets is available on our page on this topic.

Whilst there may be a benefit in increasing protein intakes for athletes and those recreationally active to a high level, the importance of high protein diets is often overstated for the general population. It is a common misconception that high protein intakes alone increase muscle mass and focussing too much on eating lots of protein can mean not getting enough carbohydrate, which is a more efficient source of energy for exercise.

It is important to note that high protein intakes can increase your energy calorie intake, which can lead to excess weight gain. The current protein recommendations for the general population are 0. If you are participating in regular sport and exercise like training for a running or cycling event or lifting weights regularly, then your protein requirements may be slightly higher than the general sedentary population, to promote muscle tissue growth and repair.

For strength and endurance athletes, protein requirements are increased to around 1. The most recent recommendations for athletes from the American College of Sports Medicine ACSM also focus on protein timing, not just total intake, ensuring high quality protein is consumed throughout the day after key exercise sessions and around every 3—5 hours over multiple meals, depending on requirements.

In athletes that are in energy deficit, such as team sport players trying to lose weight gained in the off season, there may be a benefit in consuming protein amounts at the high end, or slightly higher, than the recommendations, to reduce the loss of muscle mass during weight loss.

Timing of protein consumption is important in the recovery period after training for athletes. Between 30 minutes and 2 hours after training, it is recommended to consume g of protein alongside some carbohydrate. A whey protein shake contains around 20g of protein, which you can get from half a chicken breast or a small can of tuna.

For more information on protein supplements, see the supplements section. To date, there is no clear evidence to suggest that vegetarian or vegan diets impact performance differently to a mixed diet, although it is important to recognise that whatever the dietary pattern chosen, it is important to follow a diet that is balanced to meet nutrient requirements.

More research is needed, to determine whether vegetarian or vegan diets can help athletic performance. More plant-based diets can provide a wide variety of nutrients and natural phytochemicals, plenty of fibre and tend to be low in saturated fat, salt and sugar. Fat is essential for the body in small amounts, but it is also high in calories.

Choose lean meats and plant-based proteins like beans, legumes, tofu, nuts and seeds prepared with little or no added fats, lower fat milk products and fortified plant-based beverages. Stay well hydrated. Eat a meal or snack 1 to 4 hours before exercising to give your body the energy it needs to train.

See below for more specific information on what foods to include. When you do not get enough calories from carbohydrate, fat and protein, your performance may not be the best it could be. Then choose a few extra servings of carbohydrate-rich foods throughout the day before playing sports or exercising.

Getting enough carbohydrates helps you have enough glycogen fuel for your body stored to provide you with energy for your training session or sport. Each of these is about 1 serving of carbohydrates:. The number of extra servings you need will depend on your weight and the type of sport or exercise you are doing.

Heavier athletes need more servings than lighter athletes. Check with your dietitian for personalized recommendations. Many people think they need more protein, but usually this is not the case. You may need more protein if you exercise regularly and intensely or for longer sessions, or if you are trying to build muscle mass.

Connect with a dietitian to find out how much protein is right for you. You can get more protein by eating a few extra servings of protein foods throughout the day. Divide your protein into 3 to 4 meals and snacks throughout the day and try to include a variety of protein sources.

Sources of protein include beans, legumes, tofu, tempeh, edamame, nuts and seeds and their butters, eggs, meat, chicken, fish, dairy products like milk, cheese and yogurt, and fortified plant-based beverages.

About 1 to 4 hours before playing sports, eat a meal that is rich in carbohydrate, low in fat and fairly moderate or low in protein and fibre for quick digestion and to prevent gastrointestinal discomforts while playing or training.

Here are some examples:. Your portion size will depend on how intense or long your training session will be and your body weight. Choose smaller meals that are easier to digest closer to the time you will be exercising. During sports, training or exercise that last longer than 1 hour, your body needs easy-to-digest foods or fluids.

Protein recommendations for endurance athletes are between 1. Fats are needed to deliver essential vitamins and nutrients, fight inflammation, and support healthy hormone function. Of all the macronutrients, fat recommendations are very similar between endurance and strength-based athletes ~1.

Fat recommendations may be slightly higher for endurance-based athletes if they have very high caloric demands. The fundamentals of general recommendations are not what makes sports nutrition unique… The utilization of these different macronutrients at specific times is one of the biggest hallmarks of sports nutrition.

In the field, we call this nutrient timing. Nutrient timing is delivering specific nutrients during specific windows to significantly enhance athletic performance and promote a quick recovery.

Yes, hydration is also another key component to sports nutrition since you will be dealing with highly active individuals.

And what happens when we are active? We sweat! Therefore, ensuring adequate fluid consumption for athletes and active individuals is very important. If exercise is 60 minutes are less, water alone will be an adequate hydrator.

Electrolytes are responsible for maintaining fluid balance and are essential for normal muscle contractions. Losing electrolytes in excess is what leads to early fatigue and cramping.

Therefore, consuming electrolyte beverages during exercise for greater than one hour can enhance performance. Since enhancement in performance is the name of the game in sports nutrition, being very well versed in the field of supplements is crucial. This is one of the most widely asked topics, so understanding which supplements have merit vs which do not is key to providing your clients with helpful information.

First, supplements should not be recommended unless they pass these 5 cardinal rules:. If you're looking for an easy place to start, here is a list of supplements that have strong evidence in the use of their support:.

So, ultimately what does your day-to-day look like if you were a sports nutrition coach? The obvious duties of a sports nutrition coach will commonly take place in performance-based locations such as gyms and training centers.

You will spend most of the time monitoring your client's training and educating them on how to fuel appropriately during those sessions. You'll spend many hours educating them on the importance of nutrient timing and the use of supplements to maximize both their performance and recovery.

Additionally, you will also likely be performing body composition analyses. Understanding body composition as it relates to various athletics is a vital component of the field.

Many times, having leaner compositions is advantageous in endurance-based sports, and having higher body fat and more muscle is advantageous in power sports.

An extensive knowledge base in ideal body composition ranges for various sports will help guide your clients to appropriate, healthy body composition. But what are the not-so-obvious duties? While it's important to stay within your scope, having training in counseling, understanding psychology, and even being familiar with medical conditions or injuries is important to becoming a sports nutritionist.

Disordered eating patterns, food phobias, and distorted body images are very common in the world of sports — understanding how to counsel clients with these behaviors is pivotal to their performance.
