Athletes consistently work to improve motor performance. We also know that the development of fatigue during exercise and the onset of exhaustion occur earlier in the heat than in cooler environments. Sport performance coaches and practitioners need to have a more comprehensive understanding of the immediate and delayed effects of cryotherapy on functional performance. Herewith, precooling is a popular strategy used to combat the debilitating effects of heat-stress-induced fatigue and extend the period in which an individual can tolerate a heat-gaining environment. Sport Scientists recognize that pre-cooling can increase performance capacity in diverse temperatures and exercise circumstances. This book adresses a range of strategies designed to either reduce the heat load or enable the participant to cope with the debilitating effects of heat stress.
