High-Intensity Interval Training and Fat Mass Losses

Overview

The aims of this study was to compare two isoenergetic HIIT (High-intensity Interval training) programs (cycling vs. running) on body composition, substrate oxidation at rest and during a moderate exercise, muscle functionality, glycaemic control, lipid profile, inflammation, maximal aerobic capacity (VO2max) and gut microbiota composition in men with overweight or obesity. The investigators hypothesized that both programs could decrease total, abdominal and visceral fat mass but due to differences in muscle solicitation, metabolism adaptation and blood flow, and that running could favors greater fat mass losses.

The first aim of this study was to compare two isoenergetic HIIT programs (cycling vs. running) on body composition in men with overweight or obesity. 20 men with overweight or obesity should completed HIIT program three times a week during twelve weeks. i) High intensity interval training - BIKE (HIIE BIKE) 10 cycles of speeding up for 45 s at 80-thPHR followed by pedaling slowly (40% thPHR) for 1m30s (37min30s) ii) High intensity interval training - RUN (HIIE RUN) 9 cycles of speeding up for 45 s at 80-thPHR followed by pedaling slowly (40% thPHR) for 1m30s (35min15s) Body composition will be measured before and after HIIT program by Dual-energy X-ray absorptiometry (DXA).
