Abstract

PURPOSE: This study compared the effects of HIIT and MIIT+BFR on the adaptations in body composition, salivary hormone concentration, peak oxygen uptake, anaerobic parameters, and arterial elasticity in young overweight and obese male adults.

RESULTS: There was a significant increase in total BMC (p<0.01), leg BMC (p<0.05), and trunk BMC (p<0.05) from baseline in response to HIIT. MIIT+BFR significantly increased LFM/TFM Ratio from baseline (p<0.01). HIIT significantly decreased AIx@75 (p<0.05) and CI (p<0.05). There was a significant increase in ISO 180o Away (p<0.05), Thor Begin. (p<0.01), and Thor Mid. (p<0.05) in response to HIIT. MIIT+BFR had a superior increase in Thor Mid. (p<0.05) and significantly increased ISO 180o Toward (p<0.01), VO2peak (p<0.05), and VO2peak:Time (p<0.05). In the last training session, HIIT significantly increased salivary leptin (p<0.05), but MIIT+BFR had a superior increase in salivary leptin (p<0.01) from pre- to post exercise.

CONCLUSION: HIIT significantly improved total BMC, leg BMC, trunk BMC, and AIx@75 but decreased CI from baseline. HIIT increased quad muscle strength, whereas MIIT+BFR increased hamstring muscle strength. HIIT and MIIT+BFR significantly increased peak torque in Thor Mid and salivary leptin. Only MIIT+BFR significantly improved VO2peak.
