The purpose of this study is to investigate the effects that a form fitted, moisture-wicking fabric shirt, promoted to have improved evaporative and ventilation properties, has on the thermoregulatory, physiological and perceptual response during moderate intensity exercise in the heat for an extended duration of exercise of 90 minutes. Ten healthy subjects (7 males, 3 females), completed two heat stress tests consisting of 20 minute seated rest in a neutral environment (24°C, 60% RH), 30 minute seated rest in a hot environment (33°C, 60% RH), and 90 minutes of exercise(50% V02 peak) on a magnetically-braked cycle ergometerin a hot environment (33°C,60% RH). One stress test was conductedwith the subject wearing a short sleeved synthetic polyester shirt (81% polyester and 19% elastane) (UA) while the other was conducted with the subject wearing a short-sleeved 100% cotton shirt (COT). During the UA condition rectal temperature was not significantly different compared to the COT condition during the heat stress test, or in skin temperature other than the tricep. The UA condition showed no significant difference in sweat rate compared to the COT condition.
