项目摘要

Various motor abilities and living fitness have been necessary for aged man's life to practice their daily life and then quality of their life (QOL) have been evaluated with their performance efficiency of behavior and activities that have constructed from three components such as stability, accuracy and agility. Activity of daily living (ADL) of aged man have been considered to be depended upon their motor regulation ability, their physical fitness and sports habits on their daily life. And much more an important component to protect a fall-down happening have been thought to be a motor skill of balanceability to aged man. Those motor skills were designed to study equilibrium experiment of healthy aged man or patients of cerebellar ataxia, neuropathy and myopathy.In results of this experiment, their equilibrium were measured on movement trajectory and shift locus area during keep standing or sitting posture. Following data were acquired. 1) Healthy aged man showed sitting shift locus … More area as 0.22-0.47 cm^2 related to calendar ages and sitting trajectory as 212.9-354 mm, respectively. 2) Patients of cerebellar ataxia showed the sitting locus area such as 7.6 cm^2 modified one hundred fifty decreases than those of healthy ones. 3) Balanceability of aged man would depend on standing keep-time or muscle extensive strength of the hip joint, significantly. 4) Equilibrium of active subjects were superior to that of inactive ones 6.9-15% levels and then motor regulation of aged man would be removed by an establishment of sport habits at their daily living. 5) Evoked electromyogram (M wave) and leg muscular extensive strength were measured to promote an exercise diagnosis in order to protect accident or happening phenomenon of the aged man. Then during muscle contraction of aged man, slow Motor Units (MUs) were innervated superior to fast MUs at their EMG power spectra. 6) Related to exercise habits and fall-down accidents would be occurred during shopping, walking and climbing of daily lives activation (ADL). 7) Health-fitness performance would be developed from personal exercise motivation and daily activities at their life, individually and those health-fitness promotions of aged man should protect fall-down happening at ADL.

各种运动能力和生活适应性是老年人日常生活所必需的，而老年人的生活质量（QOL）则是以他们的行为和活动的执行效率来评价的，这些执行效率由稳定性、准确性和敏捷性三个组成部分构成。老年人的日常生活活动能力（ADL）一直被认为取决于他们的运动调节能力、身体素质和日常生活中的运动习惯。本研究对健康老年人、小脑性共济失调、神经病和肌病患者进行了平衡实验，测量了他们在保持站立或坐姿时的运动轨迹和移动轨迹面积，并对平衡实验结果进行了分析。获得以下数据。1)健康老年人坐位移位轨迹 ...更多信息面积为0.22-0.47 cm ^2，与日历年龄相关，坐姿轨迹为212.9-354 mm。2)小脑性共济失调患者的坐位面积（7.6 cm^2）较正常人减少150倍。3)老年人的平衡能力主要取决于站立保持时间和髋关节肌肉伸展力。4)运动者的平衡能力比不运动者高上级6.9-15%，在日常生活中建立运动习惯可解除老年人的运动调节。5)为了预防老年人意外或突发现象的发生，通过对老年人诱发肌电图（M波）和下肢肌肉伸展力的检测，以促进运动诊断。结果表明，老年人肌肉收缩时，慢运动单位（MU）的肌电功率谱上级快运动单位（MU）。6)日常生活活动（ADL）中购物、步行、攀爬时易发生跌倒事故，与运动习惯有关。7)健康体适能表现的发展是个人运动动机与日常生活活动的结果，而老年人的健康体适能促进措施应能预防日常生活活动能力下降。少
