Summary

This study will compare the metabolic, appetite, energy intake, and perceptual responses to a bout of exercise completed in the evening after after a low-carbohydrate lunch meal (\<10% carbohydrate content / 0.2 g/kg carbohydrate; LO-CHO), with the responses to exercise performed after a lunch meal containing a high carbohydrate content (\~60% carbohydrate content / 2.2 g/kg carbohydrate; HI-CHO), and after skipping lunch and fasting for 8 hours since breakfast (FAST).

Conditions

Interventions

BEHAVIORAL

Low-Carbohydrate Pre-Exercise Meal

Sixty minutes of cycling at 60% VO2peak will take place on a stationary bicycle ergometer at 16:00, after having consumed a low-carbohydrate lunch meal (\<10% carbohydrate; 35% estimated energy requirements) 2.5 hours prior.

BEHAVIORAL

High-Carbohydrate Pre-Exercise Meal

Sixty minutes of cycling at 60% VO2peak will take place on a stationary bicycle ergometer at 16:00, after having consumed a high-carbohydrate lunch meal (\~2.2 g/kg carbohydrate; 35% estimated energy requirements) 2.5 hours prior.

BEHAVIORAL

Fasted Exercise

Sixty minutes of cycling at 60% VO2peak will take place on a stationary bicycle ergometer at 16:00, after having skipped lunch, and having consumed nothing other than plain water since breakfast (08:00; 25% estimated energy requirements). Exercise will therefore commence after an 8 hour period of fasting.
