Heat Acclimation, Hand Cooling Efficacy, and Adaptation Maintenance.

Heat Clinical Trial

Official title:
The Effect of Heat Acclimation on Repeated Bouts of Strenuous Heat Stress, Hand Cooling Efficacy, and the Maintenance Thereof.

Clinical Trial Summary

This study had three aims:

1. To determine the impact of consecutive days of exercise on thermoregulation and cardiovascular strain.

2. To determine the efficacy of a hand cooling device to cool individuals throughout a heat acclimation period.

3. To assess the maintenance of thermoregulatory and cardiovascular adaptations derived from heat acclimation during a 25-day intermittent exercise-heat exposure protocol.

Clinical Trial Description

Participants completed 14 days of exercise heat acclimation in either a hot or cool environment, followed by a heat or cool exercise exposure every 5th day for 25 days. Cardiovascular, thermoregulatory, and perceptual strain were measured throughout exercise each day. Hydration assessment and stress response via blood biomarkers were measured before and after exercise. Aerobic capacity was measured before and after heat acclimation as well as after the intermittent exercise-heat exposure. Hand cooling was implemented periodically during exercise-heat stress visits to determine cooling efficacy before and after heat acclimation. ;
