The Effect of Ventilated Vest on Thermoregulation During Exercise in Hot Environment

The purpose of this preliminary experiment is to measure the effect of a novel ventilation system on the physiological strain during exercise in high heat load while wearing ballistic protective vest. Ten young and healthy participants will participate in the study. They will all go through a six days heat acclimation period in a heat chamber according to a valid protocol. Afterwards they will be randomly exposed to 4 conditions during four separate consecutive days.
