Hip joint power during walking and running. In the shaded interval of both walking and running, the hip joint extends from about 10 degrees of flexion position to the maximum extension position, corresponding to a period of negative power; Then, the hip joint flexes from the maximum extension position, corresponding to a period of positive work. The dataset of walking is the mean value of 7 participants (mean ± s.t.d; age, 26.9 ± 3.0 years; height,169.2 ± 7.0 cm; weight, 66.3 ± 14.2 kg), which is reported by [42]; The dataset of running is the mean value of 7 participants (mean ± s.t.d; age, 32.7 ± 5.6 years; height, 176.9 ± 6.2 cm; weight, 67.0 ± 8.9 kg), which is reported by [43]
