Abstract
Fluid balance directly effects physical performance. Water, the most abundant substance in the human body, has remarkable heat-stabilizing properties. This crucial fluid mitigates the metabolic heat load brought on by exercise and serves to stabilize body temperature during environmental heat stress. In this chapter, we will review water intake versus water loss and how this fine balance is challenged during exercise. We will examine the detrimental effects of an altered fluid balance, which can result in dehydration, heat illness, electrolyte shifts, and hyponatremia. Maintaining optimal hydration therefore is key to athletic performance. This chapter will describe methods of monitoring hydration status and review rehydration strategies before, during, and after exercise.
