Objective

Obesity, being a world epidemic, is responsible for an increased risk of mortality and various comorbidities. The loss of weight, particularly of body fat, would lower this risk. This is why we have developed an aerobic, resistance and interval training program over a 6-week period whose main goal is to reduce body fat by 5%.

Material/patients and methods

We have assessed the evolution of body fat by bioelectrical impedance analysis, of VO2peak
VO 2 peak
by a cardiac stress test on a cycle ergometer, of leg muscular strength, of quality of life by the SF-36 health survey, in 20 sedentary, moderately to severely obese patients between the age of 18 and 70 years old, before and after a 6-week training program mixing aerobic, resistance and interval training exercises for 45 minutes, twice daily and 5 days per week, with a food rebalancing with normocaloric diet. A follow at 3 months was performed on body fat.

Results

After the 6-week training program the body fat decreases of 8,2 ± 3,9%, VO2peak
VO 2 peak
increases of 14,2 ± 16,3%. Muscular strength increases of 15,8 ± 13% and quality of life increases of 80,7 ± 70%. The follow-up shows a decrease of body fat at 3 months.

Discussion–conclusion

In patients with moderate to severe obesity, a mixed 6-week training program, without hypocaloric diet leads to a significant decline in body fat as well as an increase in VO2peak
