以前研究鞋中底硬度对跑步运动学影响的研究通常使用年龄范围较窄的男性受试者。目前尚不清楚鞋中底硬度对男女跑步者以及不同年龄段的跑步者是否具有相同的运动学影响。由于性别和年龄对跑步运动学有影响，了解鞋中底硬度是否以类似的方式影响这些群体的运动学是很重要的。然而，目前关于性别和年龄对跑步运动学影响的文献也局限于他们研究人群中狭窄的年龄范围分布。因此，本研究测试了三种不同的中底硬度条件，性别和年龄对后跟-脚趾跑过程中腿部运动学的影响。采用综合分析方法对93名16~75岁跑步者(男、女)的下肢运动学步态变量进行分析。参赛者以3.33+/-0.15米/S的速度在30米长的跑道上以软、中、硬三种中底奔跑。结合支持向量机的主成分分析表明，基于鞋底硬度、性别和年龄的跑步运动学是可分离和可分类的。鞋底硬度对跑步运动学的影响与受试者无关。此外，研究发现，与跑步者性别的差异相比，年龄差异对跑步中更主要的运动成分产生了更大的影响。(C)2012爱思唯尔有限公司。保留所有权利。
Previous studies investigating the effects of shoe midsole hardness on running kinematics have often used male subjects from within a narrow age range. It is unknown whether shoe midsole hardness has the same kinematic effect on male and female runners as well as runners from different age categories. As sex and age have an effect on running kinematics, it is important to understand if shoe midsole hardness affects the kinematics of these groups in a similar fashion. However, current literature on the effects of sex and age on running kinematics are also limited to a narrow age range distribution in their study population. Therefore, this study tested the influence of three different midsole hardness conditions, sex and age on the lower extremity kinematics during heel-toe running. A comprehensive analysis approach was used to analyze the lower-extremity kinematic gait variables for 93 runners (male and female) aged 16-75 years. Participants ran at 3.33 +/- 0.15 m/s on a 30 m-long runway with soft, medium and hard midsoles. A principal component analysis combined with a support vector machine showed that running kinematics based on shoe midsole hardness, sex, and age were separable and classifiable. Shoe midsole hardness demonstrated a subject-independent effect on the kinematics of running. Additionally, it was found that age differences affected the more dominant movement components of running compared to differences due to the sex of a runner. (C) 2012 Elsevier Ltd.
