文题释义:
身体晃动指数:当受试者站立于测试平台上,身体压力中心在各方向上有一定的移动,设备通过计算左右前后方向移动轨迹和位移来确定受试者的身体晃动指数,越小说明平衡稳定性越好。
峰力矩:等速肌力测试指标之一,能衡量测试关节在测试角度内最大力矩值,能反映受试者该关节在相应角速度测试下的肌力水平。
摘要
背景:
目前缺乏较系统衡量倒走运动对老年女性身体姿势控制能力影响的报道。
目的:探讨有规律的倒走运动对健康老年女性平衡能力、下肢肌力和下肢神经肌肉反应时的影响。为倒走运动提升老年姿势控制能力预防跌倒提供理论依据。
方法:在2017年2至3月在成都市武侯区庆安社区招募有健身意愿的健康老年女性,经随机分组,分为年龄、身高和体质量相匹配的实验组(n=28)和对照组(n=26)。实验组进行为期24周(3次/周,70 min/次)的倒走干预。
结果与结论:24周后,与对照组相比,实验组静态平衡测试的稳定坚硬平板闭眼站立身体晃动指数、海绵垫闭眼站立身体晃动指数减小,动态平衡测试向后方向得分增加,膝关节屈绝对力、爆发力和踝关节伸爆发力增加,胫骨前肌及腓肠肌前反应时缩短。提示24周倒走能提高老年女性受试者的平衡能力,增加下肢肌力,缩短下肢神经肌肉反应时,能有效提升老年人身体姿势控制能力。

Abstract:

BACKGROUND: There is a lack of systematic study concerning the impact of backward movement on the physical posture control in elderly women.
OBJECTIVE: To explore the effect of regular backward exercise on the balance, muscle strength and neuromuscular response latency of the lower extremities in healthy elderly women, so as to provide a theoretical basis for backward exercise improving the ability of controlling the posture to prevent falling in older adults.
METHODS: Healthy elderly female volunteers recruited in Qing’an community in Wuhou District, Chengdu were recruited between February and March 2017, and randomly divided into experimental group (n=28) and control group (n=26), which were matched in age, height and body mass. The experimental group was subjected to backward exercise (70 minutes/time), thrice weekly for 24 weeks.
RESULTS AND CONCLUSION: After 24 weeks, in the static balance test, there was a decrease in the Sway index in standing on a fixed platform/sponge mat with eyes closed. In the dynamic balance test, the score of backward was increased, the absolute/explosive force of knee joint flexion, and the force and explosive force of ankle joint extension were increased; the anterior response latency of tibialis anterior and gastrocnemius was reduced. To conclude, 24-week backward exercise can improve the balance ability of the elderly female subjects, enhance the muscle strength of lower extremities, and shorten the neuromuscular response latency of lower extremities, thus effectively promoting physical posture control.|
