Training nutrition -
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. Supplements should not be taken without the advice of a qualified health professional. The ethical use of sports supplements is a personal choice by athletes, and it remains controversial.
If taking supplements, you are also at risk of committing an anti-doping rule violation no matter what level of sport you play. Dehydration can impair athletic performance and, in extreme cases, may lead to collapse and even death. Drinking plenty of fluids before, during and after exercise is very important.
Fluid intake is particularly important for events lasting more than 60 minutes, of high intensity or in warm conditions. Water is a suitable drink, but sports drinks may be required, especially in endurance events or warm climates.
Sports drinks contain some sodium, which helps absorption. While insufficient hydration is a problem for many athletes, excess hydration may also be potentially dangerous.
In rare cases, athletes might consume excessive amounts of fluids that dilute the blood too much, causing a low blood concentration of sodium.
This condition is called hyponatraemia, which can potentially lead to seizures, collapse, coma or even death if not treated appropriately.
Consuming fluids at a level of to ml per hour of exercise might be a suitable starting point to avoid dehydration and hyponatraemia, although intake should ideally be customised to individual athletes, considering variable factors such as climate, sweat rates and tolerance.

Nutrition and exercise The link between good health and good nutrition is well established. Daily training diet requirements The basic training diet should be sufficient to: provide enough energy and nutrients to meet the demands of training and exercise enhance adaptation and recovery between training sessions include a wide variety of foods like wholegrain breads and cereals , vegetables particularly leafy green varieties , fruit , lean meat and low-fat dairy products to enhance long term nutrition habits and behaviours enable the athlete to achieve optimal body weight and body fat levels for performance provide adequate fluids to ensure maximum hydration before, during and after exercise promote the short and long-term health of athletes.
Carbohydrates are essential for fuel and recovery Current recommendations for carbohydrate requirements vary depending on the duration, frequency and intensity of exercise. Exercise triggers the breakdown of muscle protein. The rate at which this happens depends on the exercise and your level of training, but even well-trained athletes experience muscle-protein breakdown 1 , 2 , 3 , 4 , 5 , 6.
Consuming an adequate amount of protein throughout the day gives your body the amino acids it needs to repair and rebuild these proteins. It also gives you the building blocks required to build new muscle tissue 1 , 7 , 8 , 9 , Depending on your body weight, grams of protein every 3 to 4 hours is recommended 1.
In addition, eating protein before exercise may decrease the amount you need to eat after without affecting recovery 1. One study found that eating protein pre-workout and post-workout has a similar effect on muscle strength, hypertrophy, and body composition changes The rate at which your glycogen stores are used depends on the activity.
For example, endurance sports cause your body to use more glycogen than resistance training. For this reason, if you participate in endurance sports running, swimming, etc. Eating a high carb diet of 3. Furthermore, insulin secretion, which promotes glycogen synthesis, is better stimulated when carbs and protein are consumed at the same time 10 , 11 , 12 , Therefore, consuming carbs and protein after exercise can maximize protein and glycogen synthesis 13 , Early studies found benefits from consuming the two in a ratio of 3 to 1 carbs to protein.
When rapid recovery is necessary under 4 hours , current recommendations suggest a similar ratio. Specifically, you can help restore glycogen faster by consuming 0.
Recommendations for carb intake are targeted to the needs of endurance athletes. There is not enough evidence to say whether you should limit fat intake after a workout 1. Many people think that eating fat after a workout slows digestion and inhibits the absorption of nutrients. While fat might slow down the absorption of your post-workout meal, it may not reduce its benefits.
For example, a study showed that whole milk was more effective at promoting muscle growth after a workout than skim milk Having some fat in your post-workout meal may not affect your recovery.
But more studies are needed on this topic. A post-workout meal with protein and carbs will enhance glycogen storage and muscle protein synthesis.
Consuming a ratio of 3 to 1 carbs to protein is a practical way to achieve this. However, more recent research has found that the post-exercise window to maximize the muscular response to eating protein is wider than initially thought, up to as many as several hours Also, recovery is not just about what you consume directly after working out.
When you exercise consistently, the process is ongoing. It is best to continue to eat small, well-balanced meals of carbs and protein every 3—4 hours Eat your post-workout meal soon after exercising, ideally within a few hours.
However, you can extend this period a little longer, depending on the timing of your pre-workout meal. Choosing easily digested foods will promote faster nutrient absorption. Combinations of the foods above can create great meals that give you all the nutrients you need after exercise.
It is important to drink plenty of water before and after your workout. Being properly hydrated ensures the optimal internal environment for your body to maximize results. During exercise, you lose water and electrolytes through sweat.
Replenishing these after a workout can help with recovery and performance Depending on the intensity of your workout, water or an electrolyte drink are recommended to replenish fluid losses.
It is important to get water and electrolytes after exercise to replace what was lost during your workout. It stimulates muscle protein synthesis, improves recovery, and enhances performance during your next workout.
Finally, replenishing lost water and electrolytes can complete the picture and help you maximize the benefits of your workout. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.
