体育舞蹈对老年人下肢等长肌力指标的影响

摘要

目的：研究体育舞蹈对老年男性下肢等长肌力的影响及对肌力下降的预防和康复治疗作用。方法：在问卷调查的基础上，筛选20名参与体育舞蹈健身运动2年以上的老年人为体育舞蹈组，20名无体育舞蹈和其它健身运动的老年人为对照组。结果：与老年对照组相比，老年体育舞蹈组的下肢等长肌力显著增大（P<0.01）。结论：老年人下肢等长肌力显著下降；体育舞蹈有助于改善下肢等长肌力持续收缩时间，增强等长肌力，对老年性下肢等长肌力下降具有预防和康复治疗作用。%Objective: To research the effects of sport dance on isometric muscle force of lower limb in the male elderly and the prevention and rehabilitation treatment muscle weakness. Methods: On the questionnaire, screening 20 elderly men who go into sport dance over two year as the sports dance group and the 20 elderly men whithout sport dance or other exercises as the control group. Results:Compared with the control group, lower limb isometric muscle force in the sports dance group was increased significantly (P<0.01). Conclusions: The lower limb isometric muscle force in the elderly was decreased significantly. Sports dance was contributive to improve continuing contraction time and increase isometric muscle force. Sports dance have prevention and rehabilitation action to senile lower limb isometric force weakness.
