Effectiveness of hand cooling and a cooling jacket on post‐exercise cooling rates in hyperthermic athletes [PDF]
European Journal of Sport Science, 2018 AbstractThis study compared the effects of a hand cooling glove (∼16°C water temperature; subatmospheric pressure of −40 mmHg) and a cooling jacket (CJ) on post‐exercise cooling rates (gastrointestinal core temperature, Tc; skin temperature, Tsk) and cognitive performance (the Stroop Colour–Word test). Twelve male athletes performed four trials (within
