自行车骑行效率的影响因素研究进展

Research Progress about the Influencing Factors of Cycling Efficiency

自行车骑行效率通常被定义为自行车骑行过程中一定氧耗和能耗水平下的功率输出,自行车骑行能力的增强,多伴随骑行效率的提高。性别、年龄、骨骼肌纤维类型的差异会对骑行效率产生不同影响;而自行车骑行过程中踏蹬技术、身体姿态,甚至运动器材的变化,则可通过改变踏蹬过程中骨骼肌发力和能耗影响骑行效率;专业自行车运动员的骑行效率与训练强度呈正相关关系,阶段性的肌力或专项训练可能通过提高做功和能量节省化促进骑行效率的提高。

Cycling efficiency is generally defined as the power output due to a certain level of oxygen and ener- ,umption gy eonsumimprovement of riding capacity is always accompanied with increased cycling efficiency. C eletal muscle fiber type may have different effect on cycling efficiency. And the changes of pedaliody posture and bicycle equipment can affect eycting efficiency by altering the power of pedal gy consumption in the course of pedaling. The cycling efficiency of a professional cyclist is ted to training intensity. Periodical muscle strength training or special training may promote by improving work Output and energy saving.
