Pre-cooling for athletic performance means more energy for the competition itself.
Recovery cooling between events can keep you playing stronger longer.
When we exert energy in warm environments, 75% of our energy is lost to heat rather than power.
José González-Alonso, professor of sport and exercise physiology at Brunel University explored the complex interactions in the human body when subjected to high heat and high levels of physical activity. The result of his 2008 research was, in part, that our bodies actually gain heat from both the environment and our own muscle movement. When the temperature of the environment is greater than our skin temperature, that heat will be transferred into our body. As well, when we exercise, our contracting muscles also produce heat.
The study also proved that fatigue is caused from an increase in brain temperature, and not tired muscles.
So why should you pre-cool when exerting energy in warm environments?
Why should you recovery cool?
