Typically, the body Pwrformance levels of team sport players do not reach the low nutritkon typical of endurance athletes such as runners, cyclists and triathletes. However, recent observations among professional team Performance nutrition plans for team sports have noted a reduction in body fat levels across players in general Duthie et al.
The requirement to wear lycra bodysuit uniforms in some team competitions has also contributed to an increased interest in loss of body fat among team players, although in this case it may be driven by aesthetic interests as much as by performance goals.
Table 2 summarizes the risk factors and strategies to manage unwanted gain of body fat among players in team sports. Recent research using tracer techniques has focused on the best feeding strategies following a bout of resistance exercise.
Various investigations have found that the maximal protein synthetic response is produced when resistance exercise is followed by the immediate intake of rapidly digested, highquality protein Tang et al.
Despite the belief that large amounts of protein are needed for gains from resistance exercise, a dose—response study has found that the maximal synthetic response to a training bout was achieved with the intake of 20 to 25 g of high-quality protein following exercise Moore et al.
Over a hour recovery window, regular feeding i. every 3 hours of a moderate quantity [20 g] of rapidly digested whey protein will continue to promote high rates of muscle protein synthesis following resistance training Areta et al. As a general rule, including ˜0. Furthermore, a well-scheduled intake of high-quality protein foods is likely to restrict the loss of muscle mass and strength during recovery from injury Wall et al.
Table 2: Risk factors and strategies to manage unwanted gain of body fat among players in team sports adapted from Burke, Strategies to address risk factor. Substantial reduction in activity levels during the off-season or injury. Poor nutrition knowledge and practical skills leading to poor food choices, convenient low-quality ready-prepared meals and reliance on takeaway foods.
supermarket tours, cooking classes to teach domestic skills and knowledge of sound choices in restaurants and takeaway outlets. Chaotic meal patterns and displaced meals leading to poor awareness of actual food intake in a day. Residential situation e.
college, foster family exposing athlete to inappropriate food choices and food volume. Constant travel, leading to disturbance of home routine; game schedule of frequent matches where emphasis is on fuelling and recovery.
Regular excessive intake of alcohol, often in conjunction with inappropriate eating. There are few studies of the fuel demands of team sport players during training or competition, with the available evidence being focused on the match play of soccer players.
Significant muscle glycogen depletion has been shown to occur over the course of a football match Ekblom, ; Saltin, ; Krustrup et al. The current guidelines for carbohydrate intakes amended to suit a range of needs for team players are summarized in Table 3.
As such, team sport athletes should be appropriately educated to manipulate their daily fuel intake to match the demands of training and competition. Higher intakes may be required for younger team players to accommodate for growth and development, for leaner players with high daily energy requirements and for athletes striving to gain lean muscle mass to maintain a positive energy balance.
The lower-range carbohydrate intake recommendations are likely suitable for team players with high body fat levels given recommendations are expressed relative to body massfor athletes returning from injury or on a break where training loads are reduced, or for players striving to reduce body fat levels during a general conditioning phase of training.
The high-carbohydrate diet did not increase the ability of players to shoot or dribble. Several explanations are possible: muscle glycogen depletion may not impair the ability of the player to execute game skills; alternative fatigue mechanisms such as dehydration or increased lactate production may be causative factors in the reduction in skill performance; or the treadmill protocol employed failed to induce a degree of glycogen depletion or fatigue large enough to cause a significant fall in skill performance Abt et al.
Distance skated, number of shifts skated, amount of time skated within shifts, and skating speed were all increased in the carbohydrate-loaded players compared with the mixed diet group, with the differences being most marked in the third period Akermark et al. There are few studies of actual glycogen restoration following real or simulated competition in team sport; these are limited to soccer and show divergent results with both success Zehnder et al.
Potential reasons for failure to refuel effectively after competition include interference with glycogen storage due to the presence of muscle damage arising from eccentric activities Zehnder et al. Current sports nutrition guidelines for everyday eating recommend that athletes consume adequate carbohydrate to meet the fuel requirements of their training programme, thus allowing training sessions to be undertaken with high-carbohydrate availability for review, see Burke, There are a number of potential ways to reduce carbohydrate availability for training, including doing two training sessions in close succession without opportunity for refuelling Hansen et al.
As reviewed by Burkeit should be pointed out that these strategies do not involve a low carbohydrate intake per se, or follow the currently topical low-carbohydrate high-fat diet.
Furthermore, they do not advocate low carbohydrate availability for all training sessions; indeed, studies report a reduction in selfchosen training intensity with " train low " sessions, which may account for a failure to achieve an overall improvement in performance Yeo et al.
Morton and colleagues Morton et al. Further work, including a more sophisticated approach to periodizing carbohydrate availability around different training sessions, is needed.
These include inadequate fuel and fluid status; factors that can be addressed by the intake of appropriate drinks and sports products during a match. Given the intermittent nature of team sports, they often offer frequent opportunities to ingest fluid and energy during breaks between periods, time-outs, substitutions or breaks in play see Burke, Drinking opportunities for selected team sports are summarized in Table 4.
Fluids must be consumed at sidelines; players must not leave field. Third-time breaks, time-outs, substitutions, pauses in play. Half-time break, substitutions, pauses in play. Trainers may run onto field with fluid bottles during pauses in play. Half-time break, pauses in play drink must be taken at sideline.
First to 3 sets, limited substitutions, time-outs. Sweat rates for team sport players are underpinned by the intermittent high-intensity work patterns, which are variable and unpredictable between and within team sports. Even from match to match, the same player can experience different workloads and sweat losses due to different game demands and overall playing time.
Fluid losses are also affected by variable climate and environmental conditions in which team sports are played e. outdoor vs. indoor; on sunny beach vs. on ice and in some sports the requirement to wear protective clothing, including body pads and helmets.
Garth and Burke recently reviewed fluid intake practices of athletes participating in various sporting events. They noted that most of the available literature involves observations from football soccer games, and there is little information on practices on other team sports, such as rugby league, rugby union, cricket, basketball and beach volleyball for review, see Garth and Burke, Studies that have included a test of pre-game hydration status in conjunction with fluid balance testing found that a subset of players reported on match day with urine samples consistent with dehydration.
Overall, mean BM changes over a match ranged from ˜1 to 1. One study reported that the total volume of fluid consumed by players was not different when they were provided with sports drink and water compared with water alone. In addition, mean heart rate, perceived exertion, serum aldosterone, osmolality, sodium and cortisol responses during the test were higher when no fluid was ingested.
Nevertheless, Edwards and Noakes suggest that dehydration is only an outcome of complex physiological control operating a pacing plan and no single metabolic factor is causal of fatigue in elite soccer.
The subjects were able to continue running longer when fed the carbohydrate-electrolyte solution. Ali et al. The carbohydrate-electrolyte solution enabled subjects with compromised glycogen stores to better maintain skill and sprint performance than when ingesting fluid alone.

| How to create meal plans your athletes will want to follow | As regards protein foods , the advice is to vary both plant and animal sources , alternating between white and red meat, oily fish rich in Omega-3, eggs and pulses. Finally, lipids also play a very important role in the health of athletes, as they are essential for providing energy , protecting vital organs and transporting vitamins. Lipids are found in oils and some fatty foods such as avocado. Another aspect not to be underestimated in sports nutrition for team sports is what to eat before and after workouts. Before physical activity , the advice is to eat a light snack, such as fruit, low-fat yoghurt or a smoothie; while sports nutrition after physical activity must be more substantial because it is intended to restore glycogen supplies. This is why during recovery it is advisable to consume mostly carbohydrates, due to their energy availability, but also proteins, which are indispensable both for repairing tiny muscle damages and to prevent the loss of muscle mass. In this regard, one of the factors that determines the strengthening and growth of muscle mass is the recovery phase. Particular care must be taken to ensure the muscular recovery of athletes , regardless of the sport they are involved in. Therefore, in addition to physical rest, nutrition also plays a part in supporting the recovery of the muscles after they have been subjected to any degree of strain. Post-workout food supplements like Recover are effective in promoting fast and optimum muscle recovery. With its complete formulation, based on whey protein isolate and carbohydrates, with the addition of Sucrosomial® iron and zinc, leucine and HMB, Recover contributes to the well-being of bones and muscle mass, normal cognitive function and normal function of the immune system, as well as protecting cells from oxidative stress. It is also advisable in sports nutrition to pay particular attention to hydration : it is important to drink at least two litres of water a day, or more if intense training or competitions are scheduled during the day. In these cases, the mantra to follow is to drink water before, during and after training , in order to replenish mineral salts, promote thermal regulation and facilitate the removal of waste. It is also important to remember that the perception of thirst may be insufficient to satisfy the actual need for liquids lost through sweating, which is why it is best to drink more than you think you need. Excess fluids are easily eliminated with urine and sweat, while fluid deficits cause a significant decline in sports performance. To avoid the risk of being caught off guard by a loss of energy and cramps due to an intense loss of fluids, both during and after physical activity it is useful to keep mineral salt supplements on hand, such as Hydral , a practical pre-dosed soluble powder stick based on sodium and magnesium, with a pleasant citrus flavour, which, once dissolved in water, produces an instant hypotonic drink that helps keep sports performance high. Hydral can also be used in combination with Race Carb Caf or Endurance Carb to make a super energizing and rehydrating sports drink. Important: avoid alcohol as, in addition to causing dehydration, after physical activity it also prevents the secretion of hormones which contribute to repairing the micro-tears in the muscle mass resulting from training. Consequently, consuming alcohol prolongs muscle soreness and therefore the latency period required for muscle mass to heal completely.

That's because restricting carbs can make you feel tired and worn out, which can hurt your performance. Good sources of carbs include fruits, vegetables, and grains. Choose whole grains such as brown rice, oatmeal, whole-wheat bread more often than processed options like white rice and white bread. Whole grains provide the energy athletes need and the fiber and other nutrients to keep them healthy. Sugary carbs such as candy bars or sodas don't contain any of the other nutrients you need. And eating candy bars or other sugary snacks just before practice or competition can give athletes a quick burst of energy, but then leave them to "crash" or run out of energy before they've finished working out. Everyone needs some fat each day, and this is extra true for athletes. That's because active muscles quickly burn through carbs and need fats for long-lasting energy. Like carbs, not all fats are created equal. Choose healthier fats, such as the unsaturated fat found in most vegetable oils, fish, and nuts and seeds. Limit trans fat like partially hydrogenated oils and saturated fat, found in fatty meat and dairy products like whole milk, cheese, and butter. Choosing when to eat fats is also important for athletes. Fatty foods can slow digestion, so it's a good idea to avoid eating them for a few hours before exercising. Sports supplements promise to improve sports performance. But few have proved to help, and some may do harm. Anabolic steroids can seriously mess with a person's hormones , causing unwanted side effects like testicular shrinkage and baldness in guys and facial hair growth in girls. Steroids can cause mental health problems, including depression and serious mood swings. Some supplements contain hormones related to testosterone, such as DHEA dehydroepiandrosterone. These can have similar side effects to anabolic steroids. Other sports supplements like creatine have not been tested in people younger than So the risks of taking them are not yet known. Salt tablets are another supplement to watch out for. People take them to avoid dehydration, but salt tablets can actually lead to dehydration and must be taken with plenty of water. Too much salt can cause nausea, vomiting, cramps, and diarrhea and may damage the stomach lining. In general, you are better off drinking fluids to stay hydrated. Usually, you can make up for any salt lost in sweat with sports drinks or foods you eat before, during, and after exercise. Speaking of dehydration , water is as important to unlocking your game power as food. When you sweat during exercise, it's easy to become overheated, headachy, and worn out — especially in hot or humid weather. Even mild dehydration can affect an athlete's physical and mental performance. There's no one set guide for how much water to drink. How much fluid each person needs depends on their age, size, level of physical activity, and environmental temperature. Athletes should drink before, during, and after exercise. Don't wait until you feel thirsty, because thirst is a sign that your body has needed liquids for a while. Sports drinks are no better for you than water to keep you hydrated during sports. But if you exercise for more than 60 to 90 minutes or in very hot weather, sports drinks may be a good option. The extra carbs and electrolytes may improve performance in these conditions. Otherwise your body will do just as well with water. Avoid drinking carbonated drinks or juice because they could give you a stomachache while you're training or competing. Don't use energy drinks and other caffeine -containing drinks, like soda, tea, and coffee, for rehydration. You could end up drinking large amounts of caffeine, which can increase heart rate and blood pressure. Too much caffeine can leave an athlete feeling anxious or jittery. Caffeine also can cause headaches and make it hard to sleep at night. These all can drag down your sports performance. Your performance on game day will depend on the foods you've eaten over the past several days and weeks. You can boost your performance even more by paying attention to the food you eat on game day. Focus on a diet rich in carbohydrates, moderate in protein, and low in fat. Everyone is different, so get to know what works best for you. You may want to experiment with meal timing and how much to eat on practice days so that you're better prepared for game day. KidsHealth For Teens A Guide to Eating for Sports. |
