In walking mode, the weight of the body is supported by at least one leg. When running, there is a state where muscles burst and the body is unsupported. When the human body is in the air and the supporting legs fall to the ground, the muscles are buffered again. Jogging consumes much more calories than brisk walking. In addition, because muscles burst-fly, fly-buffer jogging at the same time. Therefore, from the perspective of losing weight and improving basal metabolism, jogging at the same speed is much more effective than brisk walking.
