Study Summary

The aim of this investigation is to provide guidance for assessing the influence of wet clothing, and its drying time, on body temperature responses during cold air exposure. Twelve healthy and fit adults (men and women aged 18-49) will complete this study. Four cold air exposures (41°F, 180 min) will be randomly conducted, each while wearing a different clothing ensemble that has been saturated by water. During each cold air exposure, you will be asked to rest for 60 min and perform weighted (38.5lbs) treadmill walking for up to 120 min.
