摘　　要：目的:速度固定6km/h的快走运动中,通过膝关节踝关节周围肌肉激活特征分析来探究最适的快走坡度。方法:采集16位男性受试者在四种坡度快走下肢股直肌、股外侧肌、胫骨前肌、股二头肌和腓肠肌外侧的肌电信号,计算肌肉的共激活比。结果:0坡度条件下,膝关节的股内侧肌∶股外侧肌的共激活比与6%坡度存在差异,踝关节周围肌肉胫骨前肌:腓肠肌外侧的共激活比与坡度6%和9%存在显著性差异,在坡度3%快走条件下共激活比与6%坡度有显著性差异。结论:跑步机坡度6%时更适合健身快走,对膝关节和踝关节的肌肉激活和稳定性更有利。Objective:To explore the optimal fast walking slope by analyzing the activation characteristics of muscles around the knee and ankle joints at a fixed speed of 6km/h.Methods:The electromyography signals of rectus femoris,vastus lateralis,tibialis anterior,biceps femoris and gastrocnemius lateralis of lower limbs of 16 male subjects were collected during fast walking on four slopes,and the muscle co-activation ratio was calculated.Results:There was a significant difference in the co-activation ratio of vastus medialis:vastus lateralis in the knee joint between the 0 slope and the 6%slope.There was a significant difference in the co-activation ratio of tibialis anterior muscle:gastrocnemius lateralis in the ankle muscles between the 0 slope and the 6%slope.Conclusion:Treadmill slope of 6%is more suitable for fast walking and is more beneficial to muscle activation and stability of knee and ankle joints.
