Preparing Alberto Salazar for the Heat of the 1984 Olympic Marathon.

In brief: Observations were made on US marathon record holder Alberto Salazar during a climatic chamber trial, heat acclimatization training, and the 1984 Olympic Marathon. The purpose was to evaluate his physiological responses to heat tolerance testing and to advise him regarding heat acclimatization, thermoregulation, and fluid discipline. Salazar was advised to avoid the showers along the race course during the marathon. Although fine-mist sprays, showers, and other skin-wetting techniques may make runners feel good, they have little effect on rectal temperature or sweat rate during a race. This applies to casual joggers as well as elite competitors.
