Exercise nutrition -

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. Therefore, whilst among recreational gym-goers protein supplementation has become increasingly popular for muscle building, it is generally unnecessary. However, after competition or an intense training session, high quality protein powders can be a more convenient and transportable recovery method when there is limited access to food or if an individual does not feel hungry around exercise, and may be effective for maintenance, growth and repair of muscle.

Platt recommends: Before: Fuel Up! Ideally, fuel up two hours before you exercise by: Hydrating with water. 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.
