This randomized crossover trial examined the impact of morning versus evening resistance exercise on excess post-exercise energy expenditure (EPEEE) in 13 experienced male participants. The study found that morning resistance exercise resulted in a significantly higher EPEEE (49.8 ± 21.0 kcal/2 h) compared to evening sessions (30.1 ± 18.8 kcal/2 h; P = 0.049), although this difference diminished when circadian rhythm adjustments were applied.
Key findings
- Morning resistance exercise led to a higher EPEEE of 49.8 ± 21.0 kcal/2 h compared to 30.1 ± 18.8 kcal/2 h in the evening (P = 0.049).
- PEEE-CR was significantly higher in the morning (194.4 ± 27.5 kcal/2 h) than in the evening (183.5 ± 32.2 kcal/2 h; P = 0.030).
- Circadian rhythm adjustments reduced the significance of EPEEE differences between morning and evening sessions.
Why it matters
Understanding the timing of resistance exercise can help optimize energy expenditure and metabolic outcomes. This knowledge is crucial for developing effective exercise prescriptions that enhance cardiometabolic health.
