“…Nevertheless, athletes quite often finish exercise in fluid deficit (Sawka et al, 2007), which has resulted in considerable interest in understanding factors influencing fluid recovery (Maughan, Leiper, & Shirreffs, 1997;Shirreffs, Armstrong, & Cheuvront, 2004;Shirreffs & Maughan, 2000;Campagnolo et al, 2017). As our research has revealed, 31.6% of men influencing one or more of the factors that limit exercise performance (Maughan, 2001).…”

Fluid intake, especially water, is essential for human life and also necessary for physical and mental function. The aim of this study is to find out whether men and women attending sport activities at the Faculty of Sports Studies of Masaryk University Brno keep their drinking regime. The research was carried out by using the questionnaire method. We obtained 186 completed questionnaire forms.Respondents were 108 men and 78 women aged 15-24. First, the anthropometric parameters such as body weight, height and BMI were taken. Based on the BMI value, respondents were divided into the following categories: underweight, ideal weight, overweight, weak obesity, middle obesity, severe obesity. In the next phase, respondents were questioned on the weekly frequency of physical activity performed and the physical activity type. Then, the questions focused on their drinking regime, amount of fluid consumed per day and type of the most frequent beverages. The research reveals that the majority of men and women belong to the ideal weight category. Most male respondents perform physical activity 3 times per week, and female respondents, twice a week. Most favourite physical activities are ball games for men and fitness for women. Most respondents keep their drinking regime. Research shows that most men (40.7%) and women (30.8%) drink between 2-2.5 litres of fluid per day. The most typical drink is water for both men and women. Most respondents, both male (65%) and women (62%), give positive responses to the question whether they believe that their fluid intake is sufficient.

“…Specifically, the administration of a CHO-electrolyte sports beverage increased energy (M: ~2.5 MJ, or ~32%; F: ~1.0 MJ, or ~25%) and CHO (M: ~186 g, or ~95%; F: ~73 g, or ~68%) intake, compared to water. The milk-based formulations also increased energy and nutrient provision (to a similar extent observed with the CHO-electrolyte sports beverage for males and to an even greater extent in females); though, these tended to increase ratings of gastrointestinal (GI) discomfort [16][17][18]. Given that in both previous investigations participants were free to leave the laboratory at the end of the recovery period, the extent to which anticipation of a subsequent exercise session influences food/fluid choices requires clarification.…”

“…These studies, involving endurance-trained males (M; n=10) [16] and females (F; n=8) [17], gave participants ad libitum access to one type of beverage (water, a CHO-electrolyte sports beverage or several milk-based formulations) and a variety of foods during a 4 h recovery period. In both instances, the different beverages were similarly effective at replenishing fluid losses.…”

“…This was attributed to: (1) the water and CHO-electrolyte sports beverage being ingested in larger volumes than the milk-based formulations, and (2) the co-ingested food improving retention of these "simple" fluids [13,14]. Importantly, however, the consumption of different beverages did influence energy and CHO intake [16,17]. Specifically, the administration of a CHO-electrolyte sports beverage increased energy (M: ~2.5 MJ, or ~32%; F: ~1.0 MJ, or ~25%) and CHO (M: ~186 g, or ~95%; F: ~73 g, or ~68%) intake, compared to water.…”

This study investigated the effect of consuming either water or a carbohydrate (CHO)-electrolyte sports beverage ('Sports Drink') ad libitum with food during a 4 h post-exercise recovery period on fluid restoration, nutrient provision and subsequent endurance cycling performance. On two occasions, 16 endurance-trained cyclists; 8 male [M] (age: 31±9 y; VO2max: 54±6 mL•kg-1 •min-1) and 8 female [F] (age: 33±8 y; VO2max: 50±7 mL•kg-1 •min-1); lost 2.3±0.3% and 1.6±0.3% of their body mass (BM), respectively during 1 h of fixed-intensity cycling. Participants then had ad libitum access to either Water or Sports Drink and food for the first 195 min of a 4 h recovery period. At the conclusion of the recovery period, participants completed a cycling performance test consisting of a 45 min fixed-intensity pre-load and an incremental test to volitional exhaustion (peak power output, PPO). Beverage intake; total water/nutrient intake; and indicators of fluid recovery (BM, urine output, plasma osmolality [POSM]) were assessed periodically throughout trials. Participants returned to a similar state of net positive fluid balance prior to recommencing exercise, regardless of the beverage provided (Water: +0.4±0.5 L; Sports Drink: +0.3±0.3 L, p=0.529). While Sports Drink increased post-exercise energy (M: +1.8±1.0 MJ; F: +1.3±0.5 MJ) and CHO (M: +114±31 g; F: +84±25 g) intake (i.e. total from food and beverage) (p's<0.001), this did not improve subsequent endurance cycling performance (Water: 337±40 W [M] and 252±50 W [F]; Sports Drink: 340±40 W [M] and 258±47 W [F], p=0.242). Recovery beverage recommendations should consider the post-exercise environment (i.e. the availability of food), an individual's tolerance for food and fluid pre-/post-exercise, the immediate requirements for refueling (i.e. CHO demands of the activity) and the athlete's overall dietary goals.

Purpose of Review Climate change is predicted to increase the frequency and severity of exposure to hot environments. This can impair health, physical performance, and productivity for active individuals in occupational and athletic settings. This review summarizes current knowledge and recent advancements in nutritional strategies to minimize the impact of exertional-heat stress (EHS). Recent Findings Hydration strategies limiting body mass loss to < 3% during EHS are performance-beneficial in weight-supported activities, although evidence regarding smaller fluid deficits (< 2% body mass loss) and weight-dependent activities is less clear due to a lack of well-designed studies with adequate blinding. Sodium replacement requirements during EHS depends on both sweat losses and the extent of fluid replacement, with quantified sodium replacement only necessary once fluid replacement > 60–80% of losses. Ice ingestion lowers core temperature and may improve thermal comfort and performance outcomes when consumed before, but less so during activity. Prevention and management of gastrointestinal disturbances during EHS should focus on high carbohydrate but low FODMAP availability before and during exercise, frequent provision of carbohydrate and/or protein during exercise, adequate hydration, and body temperature regulation. Evidence for these approaches is lacking in occupational settings. Acute kidney injury is a potential concern resulting from inadequate fluid replacement during and post-EHS, and emerging evidence suggests that repeated exposures may increase the risk of developing chronic kidney disease. Summary Nutritional strategies can help regulate hydration, body temperature, and gastrointestinal status during EHS. Doing so minimizes the impact of EHS on health and safety and optimizes productivity and performance outcomes on a warming planet.
