在本研究中，我们分析了在相同相对强度和相同绝对速度下跑步组的跑步经济性（RE）与生物力学参数的关系。16名同质男性长跑运动员在4.4 m.s-1时进行了RE测试，这相当于比通气阈值速度低11.1%。我们发现RE与生物力学变量（质心垂直摆动、步频、步幅、平衡时间、相对步幅、肘部活动范围、膝关节内部、足底着地时踝关节角度、半腱肌和股直肌肌电图活动）之间存在显著相关性。综上所述，跑步技术的改变可以影响RE并导致跑步性能的提高。
In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s-1, corresponding to 11.1% below velocity at the ventilatory threshold. We found significant correlations between RE and biomechanical variables (vertical oscillation of the center of mass, stride frequency, stride length, balance time, relative stride length, range of elbow motion, internal knee, ankle angles at foot strike, and electromyographic activity of the semitendinosus and rectus femoris muscles). In conclusion, changes in running technique can influence RE and lead to improved running performance.
