采用德国ISOMED2000等速系统获得优秀散打运动员膝关节肌群的生物力学特征。建议在进攻训练中膝关节速度达到300°/s,能充分发挥运动员小腿伸肌群的爆发能力。膝关节角度在163°～171°范围内,脚的运动速度达到最大,可起到有效踢击对方的目的;采用300°/s的速度可以快速屈小腿,可缩短动作时间,有利于运动员快速回防,同时为再次打击对方在时间上创造了条件。站位中,膝关节角度保持在159°～167°之间,下肢肌群爆发能力强,有利于运动员调整自身的身体姿势,改变重心位置,避开对方的快速进攻,可有效的保护自己;同时为快速起动进攻创造了条件。
The biomechanical characteristics of the knee muscles of excellent Sanda athletes were obtained using the German ISOMED2000 constant velocity system. It is suggested that the knee speed should reach 300 ° / s during offensive training, which can give full play to the explosive capacity of the athlete’s calf extensor group. Knee angle in the range of 163 ° ~ 171 °, the maximum movement of the foot, can play an effective kick each other’s purpose; the use of 300 ° / s speed flexor calf, can shorten the action time is conducive to rapid athletes Back to defensive, at the same time to create the conditions for the second strike against each other in time. Station, the knee angle maintained at 159 ° ~ 167 ° between the lower extremity muscle burst ability is conducive to adjust their body position athletes to change the center of gravity position to avoid the other’s fast attack, which can effectively protect themselves; At the same time to create a fast start offensive conditions.
