2 Food consumed at a pizza meal 30 minutes after end of treatment (rest or exercise). Food intake was not affected by treatment (p = 0.94), or duration (p = 0.55), but there was an effect of sex (p = 0.0029).

3Water consumed at a pizza meal 30 minutes after end of treatment (rest or exercise). Water intake was affected by exercise (p = 0.013), but not duration (p = 0.091), or sex (p = 0.054) and there was a treatment × duration interaction (p = 0.023).

4Palatability of the pizza meal. Palatability of the test meal was not affected by treatment (p = 0.95), duration (p = 0.74), or sex (p = 0.96).

5Energy expenditure was affected by duration (p < 0.0001), but not sex (p = 0.11).

6Food intake minus exercise energy expenditure was affected by treatment (p < 0.0001) and sex (p = 0.003), but not duration (p = 0.071).

7 Net energy balance = [{Food intake after exercise (kJ) - Exercise energy expenditure (kJ)} - (Food intake after rest treatment (kJ)]. Net energy balance was not affected by duration (p = 0.13), or sex (p = 0.093), and there was no duration × sex interaction (p = 0.36).
