The main objective of this study is to observe the effects of low load training under vascular occlusion (BFR) compared with low load resistance training without vascular occlusion in overweight sedentary people on parameters such as: decrease in fat mass; lower blood sugar levels as well as lower blood triglycerides and cholesterol levels; increased muscle mass; muscle strength; the reduction of the energy cost of walking; increasing the preferred walking speed; improving the walking pattern in overweight patients.~3.2 Primary and secondary endpoints~The first hypothesis is that the BFR drive will be effective in improving walking economy (thus reducing the energy cost of walking) and increasing the preferred walking speed, by improving walking patterns.~The second hypothesis is that BFR training makes it possible to modify the body composition in a slight way and to promote the gain of muscle strength in overweight individuals who do not practice physical activity beforehand. In addition, blood tests will show a decrease in blood sugar, blood triglyceride levels and cholesterol.~3.3 Study design~This single-center project aims to test the effects of low-load training under partial vascular occlusion (BFR) compared to low-load resistance training without vascular occlusion in overweight sedentary people. The main expected effects are a decrease in fat mass, an increase in muscle mass and strength, a decrease in the energy cost of walking as well as an increase in preferential walking speed. This project is part of a continuity of research in a public health context in order to propose adapted and effective physical activity programs for an overweight population unable to train with heavy loads.
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.
