“…Similar results have been reported in rugby and Australian Football, where high sweating rates led to significant hypohydration in some [ 67 , 80 ] but not all studies [ 67 , 70 ]. High mean sweating rates have also been reported in basketball [ 15 , 59 , 64 , 65 ], tennis [ 50 , 51 , 58 ], ice hockey [ 74 – 76 ], and beach volleyball [ 87 ]; however, mean BML was <2%, suggesting that drinking opportunities were sufficient to provide most athletes with enough fluid to offset sweat losses.…”

Sweat losses in team sports can be significant due to repeated bursts of high-intensity activity, as well as the large body size of athletes, equipment and uniform requirements, and environmental heat stress often present during training and competition. In this paper we aimed to: (1) describe sweat losses and fluid balance changes reported in team sport athletes, (2) review the literature assessing the impact of hypohydration on cognitive, technical, and physical performance in sports-specific studies, (3) briefly review the potential mechanisms by which hypohydration may impact team sport performance, and (4) discuss considerations for future directions. Significant hypohydration (mean body mass loss (BML) >2%) has been reported most consistently in soccer. Although American Football, rugby, basketball, tennis, and ice hockey have reported high sweating rates, fluid balance disturbances have generally been mild (mean BML <2%), suggesting that drinking opportunities were sufficient for most athletes to offset significant fluid losses. The effect of hydration status on team sport performance has been studied mostly in soccer, basketball, cricket, and baseball, with mixed results. Hypohydration typically impaired performance at higher levels of BML (3–4%) and when the method of dehydration involved heat stress. Increased subjective ratings of fatigue and perceived exertion consistently accompanied hypohydration and could explain, in part, the performance impairments reported in some studies. More research is needed to develop valid, reliable, and sensitive sport-specific protocols and should be used in future studies to determine the effects of hypohydration and modifying factors (e.g., age, sex, athlete caliber) on team sport performance.

“…Seventy five percent of young elite basketball players at the FIBA Europe U20 Championship started the tournament with a dehydration of 883 m Osmol/bm. In turn, tests involving adult NBA players during the summer basketball league revealed that 52% of tested individuals started games in the state of dehydration (USG > 1,020) [24] . During official competition in basketball the loss of fluids is significant, and can reach 2 litres per 20 minutes of the game.…”

“…Specific individual recommendations concerning the intake of fluids should be calculated based on sweat rates, sport dynamics, and individual tolerance. Some authors suggest a general rehydration protocol for basketball players: 200 mL at quarter breaks, 400 mL at half time and 100 mL at one timeout/half [24] . However, certain tests indicate the lack of appropriate supply of fluids during the game in spite of players having unlimited access to them.…”

Many researchers have unequivocally demonstrated that water of higher pH has a positive effect on the human body. In terms of undertaken research, the adjustment of acid-base balance during anaerobic effort, a decrease in the concentration of free radicals as well as the improvement of connective tissue condition is of primary importance. The aim of this study was to evaluate an influence of high alkaline water consumption on anaerobic performance and acid-base balance in professional basketball players. There was evaluating changes in parameters of blood and urine in laboratory tests (pH, pCO 2 , pO 2 , HCO 3 act, HCO 3 std, BE (ecf), BE(B), O 2 std, and ctCO 2 ). The group of fourteen adults male underwent in two experimental trials, before and after six weeks hydration tested water. Statistical analysis of blood tests showed that after ingestion of alkaline water there was a significant increase of blood pH at rest and after anaerobic exercise. The same results were obtained in urine tests, respectively 1.30 in rest and 0.93 after physical examination. The results of the specific anaerobic endurance test revealed a significant difference in performance between the tests performed after hydrating with highly alkaline water in comparison to table water. The average improvement of results equaled 0.71s. (p = 0.03). In conclusion the athletes hydrated with alkaline water showed a positive impact on acid-base balance with a significant increase of blood and urine pH. The daily intake of 2.5 -3.0 l of highly alkalized water delay in muscular acidosis during anaerobic exercise, as well as prevention of dehydration, and faster recovery.

Context: Research focusing on improving hydration status and knowledge in indoor female athletes is limited. Previous research has demonstrated hydration education is an optimal tool for improving the hydration status of athletes. Objective: To assess hydration status and fluid intake of collegiate female indoor athletes before and after a one-time educational intervention. Design: Controlled field study Setting: Collegiate women's volleyball and basketball practices Participants: Twenty-five female collegiate volleyball and basketball athletes (21±1years; 173.5±8.7cm, 72.1±10.0kg) were assessed during six days of practices. Intervention(s): Participants' hydration status and habits were monitored for 3 practice days before undergoing a hydration educational intervention. Post-intervention, participants were observed for 3 more practice days. Main Outcome Measures: Change in body mass (BM), fluid consumed, urine specific gravity (USG), urine color (Ucol), and sweat rate were recorded for 6 practice days. Participants completed a hydration knowledge questionnaire (HAQ) before and after the intervention to assess changes. Results: Three-day mean USG and Ucol were considered euhydrated pre-practice (USG 1.015±0.006, Ucol 4±1) and remained euhydrated post-practice (USG 1.019±0.005, Ucol 5±2) during the pre-intervention period. Decreases in pre-practice Ucol (p<.01) and increases (p<.01) in hydration knowledge were found post-intervention. Basketball athletes had greater BM losses from pre- to post-practice compared to volleyball (p=.000). Significant increases were found overall when comparing pre- and post-practice measures of USG and Ucol in pre-intervention period (p=.000, p=.001) and post-intervention period (p=.001, p=.000). No correlation was found between hydration knowledge and physiological indices of hydration and fluid intake. Conclusions: Overall, female collegiate indoor athletes were hydrated and knowledgeable of hydration. Variability in findings indicates further research is needed with this sport; clinically, attention should be given to individualized needs of each athlete. More research is needed to determine if a one-time educational intervention may be an effective tool for improving overall hydration in this population.
