Knowing the volume of sweat you lose (Litres), and at what rate (L/hr) is the best way to ensure that you maintain hydration during training and competition. The American College of Sports Medicine (ACSM) recommends maintaining hydration within 2% for best performance and welfare.
Maintaining fluid balance (replacing the sweat fluid you lose with appropriate fluid levels) is imperative to performing and feeling your best.
When dehydrated or cardiac and thermoregulatory (body temperature) systems are stressed further resulting in wasted energy and issues regulating core body temperature which leads to fatigue, greater stress on your body and poorer performance.
Further to this, decision making, reaction time and other cognitive functions are also negatively affected by dehydration.
