With the increase in participation by older adults in endurance events, research is needed to evaluate how exercising throughout the lifespan can affect the aging process regarding gait and mobility. The purpose of this study was to determine how the type of exercise modality one participates in will affect age-related declines observed during running. Fifty-six individuals between the ages of 18–65 who considered running, resistance training or cycling/swimming as their primary form of activity participated in this study. Kinematics were captured using a 10-camera motion capture system while participants ran at a controlled pace of 3.5 m/s (± 5%) over a 10-m runway with force platforms collecting kinetic data. Eight successful trials were chosen for analysis. A one-way ANOVA assessed differences in mean kinematic and kinetic variables of interest between physical activity groups (α = 0.05). Older resistance trainers exhibited greater maximal knee power compared to older runners. No other group differences were observed. Despite type of exercise modality, regularly participating in exercise has positive effects. This is evident through the preservation of the function of the lower extremity with age, specifically function of the ankle, and its contribution to healthy movement patterns.

运动方式对跑步过程中观察到的年龄相关变化的影响

随着老年人参加耐力项目的人数增加，需要进行研究来评估在整个生命周期中锻炼如何影响有关步态和活动能力的衰老过程。这项研究的目的是确定一个人参与的运动方式类型将如何影响在跑步过程中观察到的与年龄相关的衰退。56 名年龄在 18-65 岁之间、将跑步、阻力训练或骑自行车/游泳作为主要活动方式的人参与了这项研究。当参与者以 3.5 m/s (± 5%) 的受控速度跑过 10 米跑道时，运动学是使用 10 摄像机运动捕捉系统捕捉的，力平台收集动力学数据。选择了八个成功的试验进行分析。单向方差分析评估了体育活动组之间感兴趣的平均运动学和动力学变量的差异 (α = 0.05)。与年长的跑步者相比，年长的阻力训练员表现出更大的最大膝关节力量。没有观察到其他组差异。尽管有多种锻炼方式，但定期参加锻炼会产生积极影响。随着年龄的增长，下肢的功能得以保留，特别是脚踝的功能及其对健康运动模式的贡献，这一点显而易见。
