Cinematography was used to biomechanically compare individually selected overground jogging and running velocities with equated treadmill jogging and running by adult males and females. All subjects were regular joggers but not competitive track or cross-country runners. No significant differences were recorded in stride length, stride rate, support time or non-support time for males or females when jogging at velocities of between 3.33 and 4.78 m/s (x = 3.70) or 3.45 and 4.80 m/s (x=3.97) respectively. However, it was demonstrated that at velocities of 4.82 - 6.2 m/s for males (x - 5.41) and 4.85 - 5.76 m/s for females (x = 5.29) significant differences did occur between overground and treadmill running. For both males and females stride length decreased, stride rate increased, and the period of non-support was also significantly less when running on a treadmill as compared to running overground.
运用摄影技术,对成年男性和女性在地面上单独选择的慢跑和跑步速度与同等速度的跑步机慢跑和跑步进行生物力学比较。所有受试者均为经常慢跑者,但并非有竞争力的田径或越野跑运动员。当男性和女性分别以3.33至4.78米/秒(x = 3.70)或3.45至4.80米/秒(x = 3.97)的速度慢跑时,步幅、步频、支撑时间或非支撑时间均未记录到显著差异。然而,结果表明,男性在4.82 - 6.2米/秒(x - 5.41)的速度下以及女性在4.85 - 5.76米/秒(x = 5.29)的速度下,地面跑步和跑步机跑步之间确实存在显著差异。与地面跑步相比,男性和女性在跑步机上跑步时步幅减小、步频增加,且非支撑期也显著缩短。
