南拳难度动作连接技术的生物力学分析

Biomechanics Research on Connection Technique in Difficulty of Movement of Nanquan Wushu Routine

采用运动生物力学研究方法,分析和讨论了武术套路南拳难度动作连接难度。结果表明:提膝独立动作的失误率最高、连接难度的动动连接及动静连接技术存在差异和不同的力学特征。建议:应该注意腿部肌肉主动收缩完成着地支撑,而不是被动地着地缓冲;在难度动作完成中,动作之间具有相互帮助、相互促进和相互干扰的作用,应加强组合部分的动作训练,通过改进技术动作以减小干扰,提高动作质量;借鉴田径等其他项目的跳跃训练,提高武术运动员的跳跃能力;在南拳连接难度动作中的动动连接,第二跳的支撑腿以复合杠杆的形式完成动作,要加强支撑腿大、小腿后肌群的力量才能够满足动作力学特征的要求。

This article analyses and discusses the connection technique of movement difficulty of Nanquan which is based on sports biomechanics research. The results shows ： the individual action of raising the knees has high rate of mistakes ; it has difference and mechanical characteristics in the connecting movement between actions and between action and motionless gestures. It is suggested as follows： we should pay attention that the leg muscle should land on muscle contraction initiative, rather than passive buffer; there is mutual help and promotion and interruption between the movements; also we should have some interference in the course of finishing the movement difficulty, we should strengthen the part＇s training, and through improving technology reduce such interference, improve the quality of the movements ; one can learn jump training methods from other items such as track and field, to increase the jumping ability ; the second jump of the supporting leg was complete by multiple lever which is in the con- nection difficulty of between dynamics, it will be able to meet the mechanical characteristics with the strength of the thigh and the calf muscles of supporting leg.
