“…Dehydration and rehydration protocols were heterogeneous amongst included trials. In 57 out of the 61 trials reviewed, dehydration was accomplished via passive heat exposure ( n = 11) [ 42 , 47 , 50 – 56 ] or physical activity ( n = 47), conducted in a thermoneutral laboratory ≤25 °C ( n = 16) [ 24 , 25 , 29 , 35 , 48 , 55 , 57 – 61 ], heated environmental chamber ( n = 28) [ 22 , 29 , 33 , 36 , 37 , 41 , 46 , 49 , 62 – 71 ] or environmental conditions not specified ( n = 3) [ 72 , 73 ]. The remaining trials reduced body water content through warm water immersion ( n = 2) [ 74 , 75 ] or dietary fluid restriction in combination with 2-h moderate intensity exercise 24 h prior to testing performance ( n = 2) [ 76 , 77 ].…”

The Effect of Fluid Intake Following Dehydration on Subsequent Athletic and Cognitive Performance: a Systematic Review and Meta-analysis

BackgroundThe deleterious effects of dehydration on athletic and cognitive performance have been well documented. As such, dehydrated individuals are advised to consume fluid in volumes equivalent to 1.25 to 1.5 L kg−1 body mass (BM) lost to restore body water content. However, individuals undertaking subsequent activity may have limited time to consume fluid. Within this context, the impact of fluid intake practices is unclear. This systematic review investigated the effect of fluid consumption following a period of dehydration on subsequent athletic and cognitive performance.MethodsPubMed (MEDLINE), Web of Science (via Thomas Reuters) and Scopus databases were searched for articles reporting on athletic (categorized as: continuous, intermittent, resistance, sport-specific and balance exercise) or cognitive performance following dehydration of participants under control (no fluid) and intervention (fluid intake) conditions. Meta-analytic procedures determined intervention efficacy for continuous exercise performance.ResultsSixty-four trials (n = 643 participants) derived from 42 publications were reviewed. Dehydration decreased BM by 1.3–4.2%, and fluid intake was equivalent to 0.4–1.55 L kg−1 BM lost. Fluid intake significantly improved continuous exercise performance (22 trials), Hedges’ g = 0.46, 95% CI 0.32, 0.61. Improvement was greatest when exercise was performed in hotter environments and over longer durations. The volume or timing of fluid consumption did not influence the magnitude of this effect. Evidence indicating a benefit of fluid intake on intermittent (10 trials), resistance (9 trials), sport-specific (6 trials) and balance (2 trials) exercise and on cognitive performance (15 trials) was less apparent and requires further elucidation.ConclusionsFluid consumption following dehydration may improve continuous exercise performance under heat stress conditions, even when the body water deficit is modest and fluid intake is inadequate for complete rehydration.Electronic supplementary materialThe online version of this article (doi:10.1186/s40798-017-0079-y) contains supplementary material, which is available to authorized users.

“…Other proposed mechanisms include changes in vestibular function, as some studies have reported impaired postural balance (increased body sway) with hypohydration after exercise [ 173 – 176 ]. However, other studies have reported no impact of hypohydration on balance control [ 133 , 141 , 177 ].…”

Fluid Balance in Team Sport Athletes and the Effect of Hypohydration on Cognitive, Technical, and Physical Performance

et al. 2017

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.

“…Physical exercise can cause high sweat rates and substantial water and electrolyte loss (Erkmen et al., 2010). Lovlin et al, 1987) suggested that since mitochondrial swelling, edema formation, proteinuria, and hemolysis have been observed after exercise, perhaps, exercise induced free radical generation and its subsequent events contribute to the altered function(s).…”

The effects of sodium chloride on pH, total soluble solid, phenolics, anthocyanins, and 2,2‐diphenyl‐1‐picrylhydrazyl radical‐scavenging activity (DPPH) of grape juice during storage at 7, 20, and 30°C were investigated in this study. The results indicated that during the 6‐day storage, NaCl at concentrations of 17, 42.5, and 85 mmol/L delayed the decrease of total anthocyanins and DPPH effectively at 7, 20, and 30°C. Except for 85 mmol/L at the late stages during storage, NaCl‐treated samples showed higher levels of total phenolics than control groups stored at 7, 20, and 30°C. Additionally, samples treated with NaCl showed significantly delayed decrease of pH and total soluble solids especially at 20 and 30°C. DPPH showed positive and significant correlation with total soluble solids, total phenolics, and total anthocyanins with r of 0.298 (p < .05), 0.376 (p < .01), and 0.835 (p < .001), respectively, while no correlation with pH. Our results showed that NaCl has potential effect on maintaining the quality and extending shelf life of grape juice without preservatives. In addition, NaCl‐treated grape juice could supplement water, electrolytes lost during exercise and antioxidant substances. Practical applications In this study, effects of NaCl on quality of grape juice during storage were investigated. NaCl effectively delayed decrease of anthocyanins and antioxidant activity and has potential effect on maintaining the quality grape juice. Additionally, NaCl‐treated grape juice replenishes water, sodium, total soluble solids, antioxidant substances, etc., and provides a theoretical basis for the development of juice‐type sports drinks.
