Guidelines for the timing and amount of nutrition will vary depending on the type of athlete. For example, the ISSN advises strength athletes consume carbohydrates and protein or protein on its own up to 4 hours before and up to 2 hours after exercise. The American College of Sports Medicine ACSM also notes the importance of consuming protein both before and after exercise for strength athletes.

By contrast, endurance athletes would need to consume mostly carbohydrates and a small amount of protein roughly 1—4 hours before exercise. Both the ISSN and ACSM emphasize the role of meal timing in optimizing recovery and performance and recommend athletes space nutrient intake evenly throughout the day, every 3—4 hours.

Some people may find that consuming meals too close to the beginning of exercise can cause digestive discomfort. It is therefore important to eat an appropriate amount and not exercise too quickly after eating.

People who are training or racing at peak levels may find it challenging to consume enough food for their energy requirements without causing gastrointestinal GI discomfort, especially immediately before an important workout or race. For example, the ISSA highlights the importance of hydration and carbohydrate loading for competitive swimmers.

At the same time, it emphasizes consuming easily digestible carbohydrates, such as bananas and pasta, prior to events to avoid GI discomfort. Athletes may need to work with a sports nutritionist, preferably a registered dietitian , to ensure they consume enough calories and nutrients to maintain their body weight, optimize performance and recovery, and plan a timing strategy that suits their body, sport, and schedule.

Athletes need to eat a healthy and varied diet that meets their nutrient requirements. Choosing whole grains and other fiber -rich carbohydrates as part of a daily diet generally promotes health. However, immediately prior to and during intense trainings and races, some athletes may prefer simpler, lower fiber carbohydrates to provide necessary fuel while minimizing GI distress.

The following is an example of what an athlete might eat in a day to meet their nutritional needs. Breakfast: eggs — either boiled, scrambled, or poached — with salmon , fresh spinach , and whole grain toast or bagel.

Lunch: stir-fry with chicken or tofu, brown rice , broccoli , green beans , and cherry tomatoes cooked in oil. Dinner: a baked sweet potato topped with turkey, bean chili, or both, served with a watercress , peppers, and avocado salad drizzled with olive oil and topped with hemp seeds.

Snacks are an important way for athletes to meet their calorie and nutrition needs and stay well fueled throughout the day. Options include:.

Athletes need to plan their diet to optimize their health and performance. They should consider their calorie and macronutrient needs and ensure they eat a varied diet that provides essential vitamins and minerals. Hydration and meal timing are also vital for performing well throughout the day.

Some athletes may choose to take dietary supplements. However, they should be mindful of safety and efficacy issues and ensure that their sporting association allows them.

Both amateur and professional athletes may benefit from consulting with a sports nutritionist to help them plan the optimal diet for their individual needs and goals. Many athletes look for safe and efficient ways to boost their performance. In this article, we look at six vitamins and supplements that may help.

Medical News Today. Nuccio et al. However, it seems likely, that cognitive performance as well as sport-specific skills are becoming more impaired with a higher fluid loss e. Such large losses of fluid have been rarely reported in team sports. Nevertheless, it would be valuable to monitor sweat rate and fluid loss Figure 2 by measuring pre- and post-session body mass and by recording of fluid intake in order to define an individual drinking strategy [6].

Hydration status should be monitored by determination of urine specific gravity Table 4. Together with the urine color, this provides a practical tool to enhance knowledge and awareness of a sufficient hydration status. The measurements could be repeated on a regular basis during training sessions as well as during tournaments in humid and hot conditions to ensure sufficient fluid intake and prevent hypohydration, overdrinking and hyponatremia.

Athletes should be encouraged to start exercise well hydrated and to make use of drinking opportunities during training and games [16]. It seems reasonable to remind players to drink at sidelines e. soccer , on the bench e. ice hockey and during quarter or halfway breaks [17].

Body composition and other anthropometric characteristics e. height, body mass might depend on the type of sport and playing position [7].

Whereas an endurance-based field athlete e. soccer presents himself much leaner, a strength-based athlete e. rugby shows a high amount of fat-free mass. Thus, comparing athletes within different sports or within different playing positions is not reasonable.

Furthermore, the variability of body mass and body composition throughout a sporting year or career needs to be taken into consideration [18]. Therefore, monitoring body composition Figure 2, Table 4 over different training phases e. off-, pre- and on-season or over a career are helpful to track individual changes [7].

This is especially valuable during nutritional interventions e. during weight loss or after a major injury e. to monitor fat-free mass. Athletes are very sensitive to measurements concerning body mass.

Hence, choosing an adequate method to monitor minor changes is important. Dual energy x-ray absorptiometry DXA is a reliable and valid method with the least error, but it is expensive with limited use [18,19].

Moreover, a standardization of the procedure regarding the device, software, technician, hydration and nutritional status [20] is needed to provide a reliable measurement.

An easier way to track body composition in the field is by skinfold measurements using a caliper [21], though this method requires some expertise and the amount of fat-free mass is indirectly estimated.

Nevertheless, tracking the sum of skinfold over time is a cost-effective way to monitor fluctuations in body composition. Domestic and international travel for games and training camps is happening on a regular basis in elite teams. Limited food options may not provide the required nutrient intake.

It is important to pack non-perishable food items and fluids [22]. On destination, buffet-style food service is the most suitable and convenient to nourish athletes on an individual basis.

The menu should be adapted to the nutritional requirements, cultural considerations, special needs i. allergies, intolerances and diets e. vegetarian, vegan, cultural, religious of the athletes [23].

The athletes should be educated on their nutritional goals and know how to choose food accordingly. It can be valuable to consult a sports dietitian for specific advice or to develop a nutritional strategy Table 4, Figure 2 for the whole team travelling [23].

Due to altered conditions e. The intake of probiotics two weeks before and during a trip appears to have a marginal protective role in reducing the incidence and severity of travel-specific problems [23].

Nutritional support is key to ensure that junior players can meet the requirements for their daily school routine, training, games, growth, maturity, health and recovery. Mostly, energy demands are higher compared to adults due to growth and changes in body composition.

A severe chronic energy deficit may impair growth and maturity, develop menstrual irregularities and enhance injury and illness risk [7,25]. Players should be monitored periodically to examine changes in height-for-weight, weight-for-age, BMI-for-age and body composition [7].

Therefore, daily CHO recommendations by body mass are similar to adult players [25]. Additional CHO intake during trainings and games may be beneficial [7].

Regarding protein consumption, a daily intake of up to 1. Compared to adults, youth athletes are less effective in regulating body temperature and have lower heat tolerance [25]. Due to the greater surface area-to-body mass ratio than adults and a lower sweating capacity, junior players have an increased risk of hypohydration [25].

With their daily training schedules and school commitments, hydration is not a priority. Many youth athletes arrive for trainings and games hypohydrated [28]. They should be encouraged to ensure euhydration before commencing exercise [25].

Furthermore, a food-first approach is essential when educating junior players [29]. Generally, adolescent athletes would benefit from sports nutrition education that enhances food selection skills for their daily schedule, general health and sport performance [29].

In the past few years, the term relative energy deficiency in sports RED-S has emerged and describes the risk of an inadequate EI in athletes [30].

Energy availability is calculated from the daily EI minus exercise energy expenditure related per kg fat-free mass [].

A state of low energy availability is defined as an intake below 30 kcal per kg fat-free mass per day. Such a low intake further increases the risk for secondary health consequences like low bone mineral density, menstrual and hormonal dysfunction, depression, gastrointestinal disturbances and cardiovascular disease.

Furthermore, physical and cognitive performance reduce whereas injury and illness risk increase. The risk for low energy availability is increased in endurance, body weight sensitive and esthetic sports as well as in female athletes in general [].

Female soccer players displayed this issue of inadequate nutritional support [7,37,38]. Therefore, it seems highly important to educate female team sport athletes properly in terms of risks and consequences of RED-S [35], even though they are not part of a weight-sensitive, esthetics or endurance sport.

Moreover, the risk for micronutrient deficiencies such as iron [39], vitamin D and calcium might be increased in female athletes [27,34]. Also, numerous female athletes often stick to a vegan, vegetarian or low-CHO diet, which represents an additional risk for low energy availability and deficiencies [3].

Therefore, it is important to educate female athletes properly in terms of risks and consequences of RED-S [35] and to provide nutritional support to those athletes Figure 2 to verify an adequate macro- and micronutrient intake as well as to optimize training adaptation and performance [40].

Due to the scarce scientific literature on the special requirements of female athletes, to date, no differentiated recommendations regarding CHO intake before, during or after exercise can be given for the female athletes [34]. Adequate EI should be the first nutritional consideration as negative energy balance accelerates muscle loss especially in immobility period [41].

In conditions of sudden inactivity as a result of surgery or injury, elevating protein intakes to 1. Including leucine-rich protein and pre-sleep protein to the diet helps to achieve the protein target values [7].

anti- inflammatory, collagen, etc. They might play a role in the management and rehabilitation of different injuries, but the different phases of stage and duration of injury provide a continuum of varied nutritional needs [3].

Literature is scarce and further studies are needed to establish nutritional guidelines. By providing an adequate energy and protein intake, the first step for a successful rehabilitation is made [41]. The further intake of micronutrients through vegetables and fruits might support the healing process.

For the vast majority of athletes, carbs provide the substrate for immediate fuel. They are broken down into glucose that is stored in the liver and muscles and is readily available to support high-intensity activity. Athletes have an unequivocal need to consume high-carbohydrate foods to enhance muscle glycogen storage and deliver glucose to muscles during high-intensity, strenuous exercise [ 76 ]. Although protein and fat can both provide a substrate to meet energy requirements during physical activity, carbohydrates are the macronutrient most efficiently broken down by the body, and the only macro that can be broken down rapidly enough to fulfil energy demands during periods of high-intensity exercise when fast-twitch muscle fibers are primarily relied upon [ 76 ].
