Hydration Status

There is no question that dehydration can significantly alter exercise performance and ultimately lead to more severe medical disorders such as heat stress and heat stroke.135 136 Hydration status is also a determinant of amino acid oxidation, with cellular dehydration inducing an increase in leucine oxidation and cellular hyperhy-dration showing the opposite in resting young men.137 Although dehydration during exercise should undoubtedly increase amino acid oxidation, no study has yet been completed during endurance exercise in men or women to explore this concept. Although most athletes strive to attain optimal hydration, there are a number of factors that can limit oral intake of fluids during exercise, and every athlete in the world has undoubtedly experienced some degree of dehydration during training or competition. Consequently, the varying and episodic dehydration that all athletes experience could have some impact on protein requirements.
