Neufer PD, Young AJ, Sawka MN, 1989, Gastric emptying during exercise: effects of heat stress and hypohydration
Binary logistic regression was performed to identify if significant independent variables contributed to predicting hypohydration
where % mass loss is the percentage of body weight lost due to hypohydration
at the start of exercise.

CON, control group; EXP, experimental group.
The combined recommendation from the IOC, ACSM and International Society for Sports Nutrition (ISSN) is to calculate individual fluid needs in order to prevent hyper- and hypohydration
Because previous, uncorrected dehydration can have a negative impact on performance as well , it is also important to assess acute hydration status before a training session or competition and to correct any existing hypohydration
2010, Mild hypohydration
induced by exercise in the heat attenuates autonomic thermoregulatory responses to the heat, but not thermal pleasantness in humans.
Nutrition: training on low carbohydrate; galactose vs other carbs and caffeine; milk protein, amino acids and cherry juice for recovery; colostrum for training; vitamin C and fish oil for asthmatics; echinacea stimulates EPO; caffeine for team-sport and tennis performance; effects of mild hypohydration
col], these are the athletes at a high risk of the adverse effects of hypohydration
Other factors that increase the risk of heat-related illness in infants and children are hypohydration
(inadequate hydration during physical activity), obesity, fewer sweat glands that decrease the ability to dissipate heat, and disease processes such as cystic fibrosis and hyperthyroidism (Gutierrez, 1995).
can have significant implications on normal physiological functions of the body (1, 2).
Skin temperature modifies the impact of hypohydration
on aerobic performance.
