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 [...]

Influence of progressive fluid restriction on mood and physiological markers of dehydration in women

The present study evaluated, using a well-controlled dehydration protocol, the effects of 24 h fluid deprivation (FD) on selected mood and physiological parameters. In the present cross-over study, twenty healthy women (age 25 (se 0·78) years) participated in two randomised sessions: FD-induced dehydration v. a fully hydrated control condition. In the FD period, the last [...]

Fluid and electrolyte balance during two different pre-season training sessions in elite rugby union players.

The purpose of this study was to compare fluid balance between a resistance and aerobic training session, in elite rugby players. It is hypothesised that resistance exercise will result in a higher prevalence of over-drinking whereas during the aerobic session under-drinking will be more prevalent.As with previous fluid balance studies, this was an observational study. [...]

Effects of carbohydrate-hydration strategies on glucose metabolism, sprint performance and hydration during a soccer match simulation in recreational players.

OBJECTIVES: This study compared the effects of three carbohydrate-hydration strategies on blood glucose concentration, exercise performance and hydration status throughout simulated soccer match-play. DESIGN: A randomized, double-blind and cross-over study design was employed. METHODS: After familiarization, 14 recreational soccer players completed the soccer match simulation on three separate occasions. Participants consumed equal volumes of 9.6% [...]

Ad libitum fluid intake does not prevent dehydration in suboptimally hydrated young soccer players during a training session of a summer camp.

There is a lack of studies concerning hydration status of young athletes exercising in the heat. Purpose: To assess preexercise hydration status in young soccer players during a summer sports camp and to evaluate body-water balance after soccer training sessions. Methods: Initial hydration status was assessed in 107 young male soccer players (age 11-16 yr) [...]

Effect of preexercise soup ingestion on water intake and fluid balance during exercise in the heat.

Purpose: To determine whether chicken noodle soup before exercise increases ad libitum water intake, fluid balance, and physical and cognitive performance compared with water. Methods: Nine trained men (age 25 ± 3 yr, VO2peak 54.2 ± 5.1 ml • kg-1 • min-1; M ± SD) performed cycle exercise in the heat (wet bulb globe temperature [...]

Isokinetic and isometric muscle function of the knee extensors and flexors during simulated soccer activity: Effect of exercise and dehydration

This study investigated the influence of dehydration during soccer-type intermittent exercise on isokinetic and isometric muscle function. Eight soccer players performed two 90-min high-intensity intermittent shuttle-running trials without (NF) or with (FL) fluid ingestion (5 ml · kg(-1) before and 2 ml · kg(-1) every 15 min). Isokinetic and isometric strength and muscular power of knee flexors and knee extensors were measured [...]

Case Study: Nutrition and Hydration Status During 4254km of Running Over 78 Consecutive Days

The aims of this study were to assess the dietary intake and monitor self-reported recovery quality and clinical symptomology of a male ultra-endurance runner who completed a multi-day ultra-endurance running challenge covering 4254km from North Scotland to the Moroccan Sahara desert over 78 consecutive days. Food and fluid intakes were recorded and analysed through dietary [...]

THIRST AND HYDRATION: PHYSIOLOGY AND CONSEQUENCES OF DYSFUNCTION

The constant supply of oxygen and nutriments to cells (especially neurons) is the role of the cardiovascular system. The constant supply of water (and sodium) for cardiovascular function is the role of thirst and sodium appetite and kidney function. This physiological regulation ensures that plasma volume and osmolality are maintained within set limits by initiating [...]
