Abstract
BACKGROUND: Previously we have demonstrated acute effects of endurance exercise in different environmental temperatures. However, training within these temperatures has not been examined. The purpose of this study is to determine the effect of exercise training in different environmental temperatures on aerobic capacity, body composition, heart rate, sweat rate, core, and skin temperature. METHODS: Thirty-six recreationally trained males made 18 visits to the lab and performed a 3-week cycling training protocol in either a 7°C, 20°C, or 33°C environment. Aerobic capacity, body composition, heart rate, sweat rate, core, and skin temperature were measured before and after the acclimation period. During the 3-week acclimation training protocol heart rate, power output, temperature, and sweat rate were measured. RESULTS: In 33°C compared to 20°C subjects, VO2peak (p = 0.02) and power output (p < 0.001) were greater for 20°C subjects following training, whereas core temperature (p = 0.036), skin temperature (p < 0.001), sweat rate (p < 0.001), and heart rate (p = 0.036) were higher in 33°C subjects. Body composition improved in both conditions (p < 0.001). In 7°C compared to 20°C, VO2peak (p < 0.001), body composition (p < 0.001), core temperature (p < 0.001), sweat rate (p = 0.05), and power (p < 0.001) improved in both conditions following training. Skin temperature was lower in 7°C (p < 0.001). CONCLUSIONS: These data indicate that physiological stress produced from exercising in 33°C environments inhibits performance measures. Whereas, 7°C environments allow for greater aerobic performance and training outcomes.
