摘　　要：目的通过力学分析评估24式简化太极拳野马分鬃动作不同姿位的损伤风险。方法建立太极拳野马分鬃动作的力学模型,通过图像分析研究大腿和小腿的坐标、速度、加速度和水平角的数据,X片测量股四头肌的力臂,比较高、低姿位野马分鬃动作的股四头肌拉力、股胫关节作用力和髌股关节压力。结果与高姿位相比,低姿位时上端环节质心坐标及速度均变小,右膝关节中心坐标和速度也降低,膝关节角度从128°降到115°;膝关节力矩、股四头肌拉力、股胫关节水平作用力和垂直作用力、股胫关节承受总载荷和髌股骨关节压力均显著增加(F>37.187,P<0.001)。结论采用低姿位练习太极拳野马分鬃动作,膝关节受伤风险较高。Objective To investigate the injury risk of simplified 24-action Taiji Quan wild horse mane splitting practice at different postures with mechanical analysis.Methods The mechanical model of the action of Taiji Quan wild horse mane splitting was establishied,and then the coordinates,velocity,acceleration and horizontal angle of thigh and lower leg were determined by image analysis.The force arm of quadriceps femoris was detected by X-ray,and the quadriceps femoris tension,femoral tibial joint force and patellofemoral joint pressure of wild horse mane splitting practice with different postures were compared.Results Compared with the high posture,the coordination and velocity decreased,the average angle of knee joint decreased from 128° to 115° at the low posture;and the knee moment,the quadriceps femoris tension,femoral tibial joint force and patellofemoral joint pressure significantly increased(F > 37.187,P < 0.001).Conclusion When practicing Taiji Quan wild horse mane splitting,the risk of knee injury at the low posture is higher than that at high posture.
