“…A significant amount of research has examined the efficacy of sodium bicarbonate (NaHCO 3 ) as an ergogenic aid (Cameron et al 2010;Krustrup et al 2015;Lavender and Bird 1989;Price and Simons 2010;Tan, et al 2010). Cameron et al (2010) reported that ingestion of 0.3 g.kg -1 NaHCO 3 60 min prior to exercise had no effect on multiple indices of repeated sprint performance in elite rugby players.…”

lower for SHAM compared to PLA (P=0.020, d=0.6). There were no differences between treatments for blood lactate, blood glucose or heart rate.In summary, ergogenicity after NaHCO 3 ingestion might be influenced by expectancy which mediates perception of effort during subsequent exercise.The observed ergogenicity with SHAM did not affect our measures of cardiorespiratory physiology or metabolic flux.

“…Although teams are allowed to constantly rotate players throughout a match, the overall exercise intensity of water polo match play usually decreases as a match progresses, suggesting the likelihood of fatigue occurring during the latter stages of match play (Pinnington et al, 1998;Platanou and Geladas, 2006;Tan et al, 2009a). This finding is important, because in addition to diminishing players' engagement in intensive match play, fatigue may also have a negative impact on a player's skill proficiency.…”

“…We identified two studies that have directly assessed the efficacy of these nutritional ergogenic aids in water polo players. Tan et al (2010) failed to observe a performance benefit of acute bicarbonate supplementation in elite female water polo athletes using a simulated game, despite enhancing extracellular pH and bicarbonate levels. The authors concluded that the demands of female water polo match play may not be of sufficient overall intensity to elicit a performance enhancement from induced alkalosis.…”

“…Players were reported to perform on average 330 discrete movements per match, changing movements every 6 s. Mean distance swum per match was 700 m, and the differential predominance between perimeter players and center forwards in sprint swimming (over 2 min and under 1 min, respectively) and wrestling (less than 2 min and more than 4 min, respectively) was confirmed. In addition, the importance of repeated sprint ability for water polo players was emphasized, because players were required to perform seven repeated high intensity activity bouts per match (Tan et al, 2009a).…”

Water polo is an aquatic team sport that requires endurance, strength, power, swimming speed, agility, tactical awareness, and specific technical skills, including ball control. Unlike other team sports, few researchers have examined the nutritional habits of water polo athletes or potential dietary strategies that improve performance in water polo match play. Water polo players are typically well muscled, taller athletes; female players display higher levels of adiposity compared with their male counterparts. Positional differences exist: Center players are heavier and have higher body fat levels compared with perimeter players. Knowledge of the physical differences that exist among water polo players offers the advantage of player identification as well as individualizing nutrition strategies to optimize desired physique goals. Individual dietary counseling is warranted to ensure dietary adequacy, and in cases of physique manipulation. Performance in games and during quality workouts is likely to improve by adopting strategies that promote high carbohydrate availability, although research specific to water polo is lacking. A planned approach incorporating strategies to facilitate muscle glycogen refueling and muscle protein synthesis should be implemented following intensified training sessions and matches, particularly when short recovery times are scheduled. Although sweat losses of water polo players are less than what is reported for land-based athletes, specific knowledge allows for appropriate planning of carbohydrate intake strategies for match play and training. Postgame strategies to manage alcohol intake should be developed with input from the senior player group to minimize the negative consequences on recovery and player welfare.

“…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].…”

Team sports are based on intermittent high-intensity activity patterns, but the exact characteristics vary between and within codes, and from one game to the next. Despite the challenge of predicting exact game demands, performance in team sports is often dependent on nutritional factors. Chronic issues include achieving ideal levels of muscle mass and body fat, and supporting the nutrient needs of the training program. Acute issues, both for training and in games, include strategies that allow the player to be well fuelled and hydrated over the duration of exercise. Each player should develop a plan of consuming fluid and carbohydrate according to the needs of their activity patterns, within the breaks that are provided in their sport. In seasonal fixtures, competition varies from a weekly game in some codes to 2–3 games over a weekend road trip in others, and a tournament fixture usually involves 1–3 days between matches. Recovery between events is a major priority, involving rehydration, refuelling and repair/adaptation activities. Some sports supplements may be of value to the team athlete. Sports drinks, gels and liquid meals may be valuable in allowing nutritional goals to be met, while caffeine, creatine and buffering agents may directly enhance performance.
