The purpose of this study was to investigate changes in running kinematics for the elderly with aging. The following studies were performed.1.Test of reproducibility and validity of a physical activity questionnaire for the elderly Three hundreds and thirty-nine elder volunteers living in Ibaraki Prefecture were asked to answer physical activity questionnaire. The results showed that the reproducibility and validity were on middle level, rating from correlation coefficients.2.Estimation of the body segments parameters for Japanese elderly Twenty-seven male elderly(62 to 89 years old)were photographed to estimate masses, the locations of centers of mass(CM), and moments of inertia(MI)for body segments, applying a mathematical model. Mass ratios of the head, trunk and forearm for the elderly were larger than those of young people. With aging the mass ratio of the head increased and that of the trunk decreased while locations of CM and MI did not changed remarkably.3. Changes in running k … More inematics of master's runners with aging Forty-six male master's runners(40 to 81 years old)were videotaped during of official 5000m races with a high-speed VTR camera. Analyzes of body kinematics showed that decrease in stride frequency with age was small although running speed and stride length, especially length of nonsupport phase remarkably decreased. Although running form(motor pattern)of the elderly was affected by running speed rather than aging, the running form was characterized by larger forward lean of the trunk and less extension of the hip joint at toe-off.4. Mechanical power of the lower limb joint for the elderly in takeoff of standing long jump Subjects same as Study 2 were asked to jump as lomg as possible from standing. Mechanical powers exerted by the lower limb joints were computed with videography and force platform technique. With aging the maxima of extension moment and concentric power of the lower limb joints were significantly decreased at the hip, foot, and knee in order of the degree of decrease. Less

本研究旨在探讨老年人跑步运动学随著老化的变化。1.老年人体力活动问卷的重复性和效度检验对339名生活在茨木县的老年志愿者进行了体力活动问卷调查。研究结果表明，该方法的重复性和有效性均处于中等水平，相关系数评定。2.日本老年人身体各节段参数的估算对27名男性老年人（62~89岁）进行了身体各节段的质量、质心位置（CM）和惯性矩（MI）的估算。老年人头部、躯干和前臂的质量比大于年轻人。随着年龄的增长，头的质量比增加，躯干的质量比减少，而CM和MI的位置变化不明显.运行k的变化 ...更多信息 用高速录像机对46名40~81岁男子5000米长跑运动员进行了全程录像。身体运动学分析表明，随年龄增长，步频下降幅度不大，但跑步速度和步长，尤其是非支撑相步长显著下降。老年人的跑步形态（运动模式）受跑步速度的影响，而不受年龄的影响，但跑步形态的特点是躯干前倾较大，髋关节离地伸展较小。老年人立定跳远起跳时下肢关节的机械功率与研究2相同的受试者被要求尽可能长地从立定起跳。采用摄像和测力台技术计算下肢关节的机械功率。随着年龄的增长，下肢关节的最大伸展力矩和向心力在髋关节、足关节和膝关节显著降低，降低的程度依次为。少
