Dehydration in Sports and Exercise

Vigorous or prolonged physical activity (i.e. during endurance sport or exercise) can lead to an increase in the body’s core temperature.

This usually results in a higher sweat rate which leads to the loss of bodily fluids and electrolytes and can cause mild to moderate dehydration.

  • Optimal sports performance requires an athlete to be at their peak – physically and mentally.
  • When exercising, you lose fluid and electrolytes through sweat which can cause dehydration.
  • Dehydration can affect your mental and physical state, leading to problems that affect your performance, such as:
    • Cramps, spasms, and soreness
    • Fatigue
    • Impaired concentration
