Abstract

〔目的〕本研究の目的は,高齢者の立位での急速な運動停止を調べ,運動制御への加齢の影響を調べること.〔対象と方法〕健康若年者29名と健常高齢者26名.立位での急速な運動停止課題は足圧中心を用いた追跡運動で実施した.床反力計から足圧中心速度が計算され,反応時間,総運動時間,推進時間,制動時間が計測された.〔結果〕高齢群の反応時間と総運動時間は若年群よりも有意に延長した.高齢群の前方推進時間は若年群よりも有意に短縮した.高齢群の前方と後方の制動時間は若年群よりも有意に延長した.〔結語〕高齢者の運動時間の延長は反応時間の延長だけでなく運動を停止するために要する制動時間の延長もみられ,加齢による立位での運動停止能力の低下が明らかとなった.

[Purpose] The purpose of this study was to examine the effect of aging on the stopping motion. [Subjects and Methods] Twenty-nine healthy young adults and twenty-six healthy elderly adults participated in this study. A rapid stop task was performed in the standing posture using a visually-guided tracking task with a visual target, and the stopping motion was monitored utilizing center of pressure (COP). All signals from one force plate were recorded and the COP velocity was calculated offline; then, the reaction time, total movement time, propulsive time, and braking time were calculated. [Results] The reaction and total movement times of the elderly group were significantly longer than those of the young group. The anterior propulsion time of the elderly group was significantly shorter than that of the young group; and the anterior and posterior braking times of the elderly group were significantly longer than those of the young group. [Conclusion] These results show that the prolonged movement times of the elderly comprised not only prolonged propulsion times but also prolonged braking times, suggesting that braking ability in the standing posture declines with age.
