BFR in Overweight Sedentary Subjects

This project should allow the investigators to observe the effects of low load training under partial vascular occlusion (BFR) in comparison with resistance training at low load without partial vascular occlusion in sedentary people overweight on parameters : decrease in fat mass; increase in muscle mass 79; muscle strength; decrease in the energy cost of walking; increase in preferred walking speed; improvement in walking pattern in patients overweight. Training under partial vascular occlusion should facilitate physical activity in overweight people as it can be just as effective as a \"classic\" type training with heavy loads. Thus, this device could allow people for who wear heavy loads can present an obstacle to physical activity to feel more involved in the physical activity programs offered in medical or sports centers.
