| 摘 要： | 探讨了造成铁人三项自行车-跑换项过程中运动员常会出现不适感的原因.呼吸肌疲劳、脱水、糖原耗竭和感受器的传导反馈调整落后于身体活动变化,引起生物力学指标的不利改变,使跑的效率下降,可能是造成不适感的主要原因.自行车赛段的骑行位置和最后阶段的蹬车频率会对换项调整产生显著影响,运动员应注意根据自己的特点确定战术.换项过程中运动员身体所承受的特殊变化提示,针对比赛中将会遇到的情况进行专门训练,可能有助于提高运动员的耐受性,加快感受器的调整适应,减小生物力学指标的不利改变,减少运动损伤.

| Abstract: | This paper discussed the possible reasons that causing the cyclist's maladjustment during the transition from cycling to running in triathlon competition.The fatigue of respiratory muscle,dehydration,carbohydrate depletion and delay of sensorial adaptation were most likely the reasons of these maladjustment.The position of athletes on cycling track and frequency of pedaling at the last phase had significant influence on transition.Athletes should confirm the tactics based on their own characters.It suggested that specific training aiming at special condition occur at competition could help to improve the tolerance of athletes. |
