Brief summary
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.
Detailed description
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).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| HIIT mode and fat mass change (g) | At the first and the last training - week 1 and 12 | change of total fat mass (in grams from DXA analysis) after 3 months of training- HIIT mode comparison |
| HIIT mode and abdominal fat mass change (g) | At the first and the last training - week 1 and 12 | change of abdominal fat mass (in grams from DXA analysis) after 3 months of training- HIIT mode comparison |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Rate of carbohydrate and lipid oxidation (g.min-1) during a sub-maximal exercise by measuring gaz exchange. | At the first and the last training - week 1 and 12 | Carbohydrate and lipid oxidation rate (g.min-1) during a submaximal exercise before and after the HIIT protocol. HIIT mode comparison. |
