Exercise performance is seriously impaired if as little as 2% or more of your body weight is lost via sweat. A loss of 4% could lead to heat stroke, exhaustion and even death!
An average 80kg athlete shouldn’t lose anymore than 1.6kg after his training session!
- 70kg mustn’t lose more than 1.4kg after training
- 80kg mustn’t lose more than 1.6kg after training
- 90kg mustn’t lose more than 1.8kg after training
- 100kg mustn’t lose more than 2kg after training
- 110kg mustn’t lose more than 2.2kg after training
According to the International Society of Sports Nutrition, (2010) the average athlete sweats 0.5-2L fluid per hour (temperature, humidity and intensity dependent), meaning you should be consuming at least 1x 500ml bottle of water or isotonic beverage for every hour of training!
NOTE: Isotonic drinks such as Science in Sport GO Electrolyte Sports Fuel are advisable because it replaces both the fluid, and the minerals lost through sweating!
