This study investigated the acute physiological responses to yoga in a hot environment (40.5 degrees Celsius). Fifteen experienced females (mean age 38.5 ± 7.2) completed two yoga trials consisting of a specific routine lasting 90 minutes. Trials were performed under ambient (22 degrees Celsius/50% RH) and hot (40.5 degrees Celsius/50% RH) conditions. Measurements for heart rate, skin surface temperature, hematocrit, sweat loss, specific gravity of urine and rating of perceived exertion were recorded for each trial. There was no significant difference between measurements for specific gravity of urine or hematocrit. Significant differences were recorded between trials for heart rate, skin surface temperature, sweat loss and rating of perceived exertion. The data shows that yoga activity in the heat produced increased levels of thermal stress, but the activity was well tolerated by this group of experienced individuals.
