What do athletes drink during competitive sporting activities?

Although expert groups have developed guidelines for fluid intake during sports, there is debate about their real-world application. We reviewed the literature on self-selected hydration strategies during sporting competitions to determine what is apparently practical and valued by athletes. We found few studies of drinking practices involving elite or highly competitive athletes, even in popular [...]

Effect of exercise-induced dehydration on endurance performance: evaluating the impact of exercise protocols on outcomes using a meta-analytic procedure.

OBJECTIVE: It is purported that exercise-induced dehydration (EID), especially if ≥ 2% body weight, impairs endurance performance (EP). Field research shows that athletes can achieve outstanding EP while dehydrated > 2% bodyweight. Using the meta-analytic procedure, this study compared the findings of laboratory-based studies that examined the impact of EID upon EP using either ecologically [...]

The Effect of Ice Slushy Ingestion and Mouthwash on Thermoregulation and Endurance Performance in the Heat.

PURPOSE: To establish whether sensory factors associated with cold beverage ingestion exert an ergogenic effect on endurance performance independent of thermoregulatory and/or cardiovascular factors. METHODS: Ten males performed three trials involving 90min steady state cycling (SS) (62% VO2max) in the heat (32.1±0.9°C, 40±2.4% relative humidity) followed by a 4kJ/kg body mass time trial (TT). During [...]

The effect of prescribed fluid consumption on physiology and work behavior of wildfire fighters.

The purpose of this study was to examine 1) wildfire fighters' ability to consume the prescribed fluid volume (1200 mL h(-1)), 2) the effect of fluid intake on plasma sodium and hydration, and 3) the effect of fluid intake on firefighters' heart rate, core temperature and activity during emergency suppression shifts. METHODS: Thirty-four firefighters were [...]
