High-Intensity Interval Training and Fat Mass Losses

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.
