Effects of obesity on body temperature in otherwise-healthy females when controlling hydration and heat production during exercise in the heat.

Background: Previous studies investigating body temperature responses in obese individuals during exercise in the heat fail to control metabolic heat production or hydration status during exercise.

Purpose: To determine if there are differences in body temperature responses between obese and non-obese females when controlling metabolic heat production during exercise.

Methods: Twenty healthy females, ten obese (43.
