Abstract

Middle-age and older runners demonstrate differences in running biomechanics compared with younger runners. Female runners demonstrate differences in running biomechanics compared with males, and females experience hormonal changes during menopause that may also affect age-related changes in running biomechanics. The purpose of this study was to determine the relationship between age and running biomechanics in healthy female recreational runners. Fifty-two participants (ages 27-65 y) ran on an instrumented treadmill at 2 different self-selected speeds: easy pace and 5 km race pace. Lower-extremity kinematic and kinetic variables were calculated from 14 consecutive strides. Linear regression was used to determine the relationship between age and lower-extremity running biomechanics, controlling for self-selected running speed. There was a negative relationship between age and easy pace (R = -.49, P < .001) and age and 5 km race pace (R = -.43, P = .001). After controlling for self-selected running speed, there were no significant relationships between age and running biomechanics for either running speed. Several biomechanical variables were moderately to strongly correlated with running speed. Running speed should be considered when investigating age-related differences in running biomechanics.

女性休闲跑者年龄与跑步生物力学的关系。

与年轻跑步者相比，中年和老年跑步者在跑步生物力学方面表现出差异。与男性相比，女性跑步者在跑步生物力学方面表现出差异，女性在更年期经历的荷尔蒙变化也可能影响与年龄相关的跑步生物力学变化。本研究的目的是确定年龄与健康女性休闲跑步者的跑步生物力学之间的关系。52名参与者（年龄在27-65岁之间）在一个装有仪器的跑步机上以两种不同的自选速度跑步：轻松配速和5公里比赛配速。下肢运动学和动力学变量由连续14步计算。在控制自选跑步速度的情况下，采用线性回归方法确定年龄与下肢跑步生物力学的关系。年龄与易步率呈负相关（R = -）。49, P < .001)、年龄与5公里比赛配速(R = -。43, p = .001)。在控制了自我选择的跑步速度后，年龄与跑步生物力学之间没有显著的关系。几个生物力学变量与跑步速度有中等到强烈的相关性。在研究跑步生物力学中与年龄相关的差异时，应该考虑跑步速度。

期刊介绍： The mission of the Journal of Applied Biomechanics (JAB) is to disseminate the highest quality peer-reviewed studies that utilize biomechanical strategies to advance the study of human movement. Areas of interest include clinical biomechanics, gait and posture mechanics, musculoskeletal and neuromuscular biomechanics, sport mechanics, and biomechanical modeling. Studies of sport performance that explicitly generalize to broader activities, contribute substantially to fundamental understanding of human motion, or are in a sport that enjoys wide participation, are welcome. Also within the scope of JAB are studies using biomechanical strategies to investigate the structure, control, function, and state (health and disease) of animals.
