摘　　要：目的:探讨慢跑鞋前掌屈曲刚度对男性跑者的跑步经济性及下肢关节功的影响。方法:通过改变中底凹槽的密度和深度制作5双不同屈曲刚度的慢跑鞋(A、B、C、D、E鞋的屈曲刚度依次减小),分析11名男性跑者分别穿这5种鞋跑时的耗氧量及下肢关节做功。结果:慢跑鞋前掌屈曲刚度对男性跑者跑步经济性及慢跑支撑阶段跖趾关节的正功、负功表现出统计学差异,但对髋、膝、踝关节的机械功差异无统计学意义,中等屈曲刚度的跑鞋跖趾关节机械功与耗氧量均表现为最低,屈曲刚度最大和最小的跑鞋较高。结论:慢跑鞋前掌屈曲刚度对男性跑者的跑步经济性及跖趾关节机械功的影响呈现先减小后增大的趋势,刚度过大和过小的跑鞋均会增大跖趾关节的机械功,降低跑步经济性。慢跑鞋前掌屈曲刚度对男性跑者跖趾关节机械功的影响可能是其影响跑步经济性的原因。Objective: To investigate the effect of forefoot bending stiffness of running shoes on the running economy and joint work of lower extremity in male runners. Methods: Five pairs of running shoes with different forefoot bending stiffness were made through modifying the density and depth of grooves on midsole(the bending stiffness of shoes A, B, C, D, E were reduced in order). Eleven male running enthusiasts participated in the study and their Oconsumption and joint work of lower extremity when they ran in each type of shoes were collected and analyzed. Results: The effect of forefoot bending stiffness of running shoes on the running economy and metatarsophalangeal joint work were statistically significant, and there was no statistical difference in joint work for hip, knee, and ankle joint. The Oconsumption and metatarsophalangeal joint work of participants when they ran in shoes C were the lowest, and their Oconsumption and metatarsophalangeal joint work when running in shoes A and D were comparatively higher. Conclusion: The effect of forefoot bending stiffness of running shoes on the running economy and metatarsophalangeal joint work in male runners shows a tendency to decrease at first and increase afterwards. Running shoes with too high or too low forefoot bending stiffness would increase the metatarsophalangeal joint work and reduce running economy. The effect of forefoot bending stiffness of running shoes on metatarsophalangeal joint work may be the reason for the effect on running economy in male runners.
