Abstract
Objective: An acute bout of high intensity intermittent exercise suppresses ad-libitum energy intake at the post-exercise meal. The present study examined the effects of 12 weeks of high intensity intermittent exercise training (HIIT) compared with moderate intensity continuous exercise training (MICT) on appetite regulation. Methods: Thirty overweight, inactive men (BMI: 27.2 +/- 1.3 kg/m2; V[spacing dot above]O2Peak: 35.3 +/- 5.3 mL.kg-1.min-1) were randomised to either HIIT or MICT (involving 12 weeks of training, 3 sessions per week) or a control group (CON) (n = 10 per group). Ad-libitum energy intake from a laboratory test meal was assessed following both a low-energy (LEP: 847 kJ) and a high-energy preload (HEP: 2438 kJ) pre and post-intervention. Perceived appetite and appetite-related blood variables were also measured. Results: There was no significant effect of the intervention period on energy intake at the test meal following the two different preloads (p >= 0.05). However, the 95% CI indicated a clinically meaningful decrease in energy intake after the HEP compared with LEP in response to HIIT (516 +/- 395 kJ decrease), but not for MICT or CON, suggesting improved appetite regulation. This was not associated with alterations in the perception of appetite or the circulating concentration of a number of appetite-related peptides or metabolites, although insulin sensitivity was enhanced with HIIT only (p = 0.003). Conclusion: HIIT appears to benefit appetite regulation in overweight men. The mechanisms for this remain to be elucidated.
