Figure 1 Substrate oxidation during exercise in the heat. A. represents carbohydrate oxidation for 1 hr in the heat with gas measurements made at 4, 24, and 54 min. B. represents fat oxidation for 1 hr in the heat with gas measurements made at 4, 24, and 54 min. Open and solid symbols represent the P and CHO trials respectively. * - indicates a significant main effect of time.

Figure 2 Muscle glycogen concentration pre, post-exercise and following 3 hr of recovery. Open and solid bars represent the P and CHO trials respectively. * - indicates a significant main effect of time.

Figure 3 Muscle expression for metabolic and mitochondrial genes following 3 hr of recovery post-exercise. Open and solid bars represent the P and CHO trials respectively. * - indicates a significant main effect of time, and ^† - indicates a significant trial X time interaction.
