Responses of Obese and Non-obese Boys Cycling in the Heat

This study compared rectal temperature (T_re), heat sensation and sweating between obese and non-obese boys during cycling in the heat. Participants (aged 12–15 years) were 17 obese and 16 non-obese (BMI=29.4±4.3 and 16.8±1.7 kg · m ^{− 2}, respectively) boys. They cycled for 30-min (50–55% VO_2peak) in a climatic chamber (35°C, 45% RH) and T_re, heat sensation and sweat volume were monitored. From the start...
