Sports, 2020 Unstructured, ad libitum drinking may predispose some athletes to start exercise already slightly hypohydrated (decreased body water). The impact of pre-exercise mild hypohydration on subsequent swimming performance is still unknown.

Post-exercise rehydration: a randomized cross-over trial comparing a 100% fruit juice, a glucose-based sports drink, and water [PDF]
Journal of the International Society of Sports NutritionBackground Previous studies indicate that sports drinks may improve rehydration, compared to water, an effect likely achieved by manufacturing sports drinks to contain carbohydrates and sodium.

Hypohydration and Human Performance: Impact of Environment and Physiological Mechanisms [PDF]
Sports Medicine, 2015 Body water losses of >2 % of body mass are defined as hypohydration and can occur from sweat loss and/or diuresis from both cold and altitude exposure. Hypohydration elicits intracellular and extracellular water loss proportionate to water and solute deficits. Iso-osmotic hypovolemia (from cold and high-altitude exposure) results in greater plasma loss

Effect of hypohydration on peripheral and corticospinal excitability and voluntary activation. [PDF]
PLoS ONE, 2013 We investigated whether altered peripheral and/or corticospinal excitatory output and voluntary activation are implicated in hypohydration-induced reductions in muscle isometric and isokinetic (90°.s(-1)) strength. Nine male athletes completed two trials

Passive dehydration alters raw bioimpedance parameters: generic vs. individualized phase angle and estimated characteristic frequency [PDF]
Journal of the International Society of Sports NutritionBackground Bioelectrical impedance analysis (BIA) is commonly used to determine body composition, including estimates of total body water (TBW), intracellular water (ICW), and extracellular water (ECW). Evaluation of raw BIA data, i.e.
