Cryo Pack Cooling After Exercise-induced Hyperthermia

Stopped: The funding was never received and the study was terminated in the IRB

0Started 2021-02-01

Plain-language summary

This research study aims to examine whether Cryo Cooling packs reduce thermal and cardiovascular strain after exercise-induced hyperthermia compared to a commercially available ice pack. Secondly, the effect of Cryo Cooling packs on cognitive and exercise performance will be examined. There is no current research examining the efficacy of Cryo Cooling packs in hyperthermic individuals and this information will be helpful to establish whether Cryo Cooling Packs can be used for performance enhancement or to prevent heat illness.
