About This Calculation

The Physiology of Athletic Fluid Balance

Thermoregulation during physical exercise relies predominantly on the evaporation of sweat from the skin surface. When fluid losses exceed 2% of total body mass, aerobic capacity, mental processing velocity, and neuromuscular power begin to decline. To achieve complete fluid re-equilibration post-exercise, athletes must consume 125% to 150% of the net volume lost to account for continued urinary loss and sweating.

Limitations & Context This calculation assumes all acute mass differential represents fluid loss rather than substrate oxidation. Urine excretion during the training window should be accounted for when precise testing is performed.
