Various Team sports nutrition have found that the maximal protein synthetic response is produced when resistance exercise Improve mental clarity and memory followed by the intake of protein nutdition is high quality in nutritino of its content Tea essential amino acids and TTeam digested [[ 13 ]; West et al.

Indeed, intakes higher nutritionn this sporgs associated with greater protein nurrition. According aports table TeaamBoost energy for a healthy lifestyle mismatch between Teeam carbohydrate needs of training and sportts and dietary intake can be a cause of poor performance sportd team sports.
There are Tewm studies of the nuttition demands of team sport players during training or competition, with nuutrition available evidence soorts focused on the match play of soccer players. The current guidelines for carbohydrate intakes amended to nutritoin a range of needs for team players Tesm summarized Teaj table 3with the rationale for these recommendations now being discussed.
Fuel requirements for training and match play adapted for team players adapted from Burke and Cox [ 39 ]. There are several studies from both field and laboratory viewpoints which have examined the value of fuelling up in preparation for team sport.
In one investigation, professional soccer players completed an intermittent high-intensity protocol of field and treadmill running lasting approximately 90 min, after a hour intake of high-carbohydrate approx. Similarly, movement analysis of a 4-a-side indoor soccer game lasting 90 min was undertaken following 48 h of high approx.
Abt et al. The findings of this study indicated that the high-carbohydrate diet did not increase the ability of players to shoot or dribble. Several explanations are possible: either 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 [ 19 ].
Finally, players from 2 elite Swedish ice hockey teams were randomly allocated to either a carbohydrate-enriched 8. 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 [ 20 ].
Rapid refuelling after the completion of the game will be important in situations where there is only a short interval between matches or where the player needs to undertake a significant training load between matches table 3.
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 [ 21 ] and failure [ 22 ] to replenish Tfam stores within 24 h.
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 [ 23 ] or contact injuries, and excessive intake of alcohol [ 24 ].
Current sports nutrition guidelines for everyday eating recommend that athletes consume adequate carbohydrate to meet the fuel requirements of their training program, thus allowing training sessions to be undertaken with high carbohydrate availability for a review, see Burke [ 25 ].
However, some studies have found that when exercise is undertaken with low muscle glycogen content, the transcription of a number of genes involved in training adaptations is enhanced for a review, see Baar and McGee [ 26 ]. There are a number of potential ways to reduce carbohydrate availability for the training environment, including doing 2 training sessions in close succession without opportunity for refuelling [ 27,28 ], or training in a fasted state with only water intake [ 29 ].
As reviewed by Burke [ 25 ], it should be pointed out that these do not always promote a low-carbohydrate diet per se nor restrict carbohydrate availability for all training sessions, and some studies have reported sporgs reduction in self-chosen training intensity [ 28,30 ].
Morton et al. All groups recorded a similar improvement in VO 2 max approx. Clearly, more work is needed on this interesting topic. Table 1 summarizes a number of nutritional factors that could be associated with fatigue during a team game. 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 [ 24 ]. Drinking opportunities for selected team sports are summarized in table 4.
Opportunities to drink during a match play in selected team sports adapted from Burke and Hawley [32]. Dehydration is directly related to reduced exercise capacity, increased perception of effort, and deterioration of mental performance and football skill performance for a review, see Burke and Hawley [ 32 ].
Various studies have shown that elite football players do not drink a sufficient amount to replace their sweat loss during training [ 33,34 ]. Maughan et al. Study results showed a large individual variability in hydration status, sweat losses, and drinking behaviors in this cool environment, highlighting the need for individualized assessment of hydration status to optimize fluid replacement strategies.
In a recent investigation, Mohr et al. McGregor et al. 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 [ 38 ] 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.
Nicholas et al. The subjects were able to continue running longer when fed the carbohydrate-electrolyte solution. More recently, 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.
In addition to the physiological and metabolic benefits, Backhouse et al. Their results showed that perceived activation was lower without carbohydrate ingestion during the last 30 min of exercise, and this was accompanied by lowered plasma glucose concentrations.
In the carbohydrate trial, rating of perceived exertion was maintained in the last 30 min of exercise but carried on increasing in the placebo trial.
These authors concluded that carbohydrate ingestion during prolonged high-intensity exercise elicits an enhanced perceived activation profile that may impact upon task persistence and performance.
Clarke et al. On a third trial, the same volume of carbohydrate-electrolyte was consumed in smaller volumes at 0, 15, 30, 45, 60, and 75 min. This manipulation of the timing and volume of ingestion elicited similar metabolic responses without affecting exercise performance. However, consuming fluid in small volumes reduced the sensation of gut fullness [ 44 ].
Nevertheless, limitations exist regarding the ability of team sport athletes to ingest fluid during match play. Indeed, gastric emptying of liquids is slowed during brief intermittent high-intensity exercise compared with rest or steady-state moderate exercise [ 45 ], and the intensity of football match play is sufficient to slow gastric emptying [ 46 ].
Like most athletes, team sport athletes are often interested in the potential ergogenic edge that could be gained by means of special supplements. These products are summarized in table 5.
Among the proposed ergogenic supplements, creatine is the one that has been investigated the most in relation with team sports, given that its purported ergogenic action i. enhanced recovery of the phosphocreatine power system matches the activity profile of team sports.
Various investigations indicate that both acute and chronic creatine supplementation may contribute to improved training and competition performance in team sports [ 47,48,49,50,51 ].
Sports foods and supplements that are of likely benefit to team sport players adapted from Burke [24]. Caffeine ingestion has also been shown to enhance team sport performance by improving speed, power, intermittent sprint ability, jump performance and passing accuracy [ 52,53,54,55 ].
However, conflicting results are not lacking in the literature [ 56 ]. Other dietary supplements with a potential but yet unclear ergogenic effect for team sport performance include induced metabolic alkalosis via bicarbonate ingestion to reduce fatigue during competition [ 57,58 ] or to enhance adaptations to training [ 59 ].
β-Alanine supplementation, to increase muscle stores of the intracellular buffer carnosine, may also provide benefits and requires further study using protocols suited to team sports [ 60 ].
Colostrum supplementation has a conflicting literature with respect to its effects on recovery and illness [ 61 ] but includes one study in which supplementation soprts 8 weeks improved the sprint performance of hockey players [ 62 ].
Dietary habits of team sport athletes have not been as well studied as those of individual sport athletes. Clark et al. Total energy, carbohydrate, protein, and fat intakes were significantly greater during the preseason. In a similar investigation, Iglesias-Gutiérrez et al.
Daily energy expenditure and energy intake were Another investigation on football players of various ages [ 65 ] also observed that the contribution of carbohydrate to total energy intake was lower than that recommended for athletes. Garrido et al.
All of the above suggest that well-designed nutritional education and interventions are necessary to optimize performance and promote healthy eating habits in team sport players. Sign In or Create an Account. Search Dropdown Menu.
