摘要
背景:前下蹬式骑行方式不适合以后蹬、后趴为主要技术特征的奔跑类运动,但迄今为止还未见模拟奔跑后扒或后蹬动作的无氧功率测试方法。目的:通过自主研发的髋受力装置实现后蹬式功率自行车抗阻骑行模式,并通过与传统Wingate法骑行方式的对比,以探索奔跑类运动项目无氧功率测试法的适宜骑行方式。方法:采用瑞士Monark自行车功量计和髋受力前伸式座椅,运用自身对比法对10名短跑运动员进行后蹬式骑行方式和经典前下蹬骑行方式无氧功率实验。观察两种骑行方式所测得的无氧功率之间的差异,并分析造成差异的生物学原因。结果与结论:髋受力后蹬式骑行方式所获得的无氧功率明显低于传统的Wingate法前下蹬骑行方式(P<0.05)。后蹬式骑行方式无论是动作结构还是肌群动员配比均较Wingate传统前下蹬骑行方式更加接近奔跑技术动作。实验结果证明用后蹬式骑行方式测得的无氧功率能够更真实地反映奔跑运动时的无氧能力。
BACKGROUND:The forward-down treading riding style of anaerobic power test by bicycle ergometer is widely used.This riding style is not suitable for the running events with the main characteristic of back driving and back pawing.Till now,the method of anaerobic test that can simulate the action of backward driving and backward pawing is not available yet.OBJECTIVE:To explore the new way of evaluating anaerobic capability in running events via comparing with traditional wingate riding style.METHODS:The Monark bicycle ergometer of Swiss and the hip-stress forward regulating seat was used in the anaerobic power test for 10 sprinters including backward driving riding style and down-forward treading riding style of classic anaerobic power test by comparison methods.The difference of anaerobic power measured by two riding style were observed and the biological reasons that caused difference were analyzed.RESULTS AND CONCLUSION:Experimental results show that the anaerobic power obtained from the hip-stress backward driving riding style was obviously lower than that of traditional down-forward treading riding style of Wingate anaerobic power test(P 0.05).The riding style of back driving was much closer to the action of running technique than Wingate traditional way,no matter in action structures or muscle groups' mobilization.The anaerobic power measured by riding style of back driving can have a more realistic reflection of anaerobic capacity of athletes.
