步速与老年人运动能力及医疗费的关系

Relations between walking pace and elderly people’s sports capacities and medical expenses

为探讨步速与老年人运动能力及医疗费的相互关系,以590名70岁以上缴纳国民医疗保险的老年人(日本)为解析对象,采用现场调查、测量及数理统计进行研究。通过动态观察4年间平均每人每月医疗费支出的情况发现,高步速组老年人的3项运动能力指标(下肢肌蹬伸力量、平衡能力、灵敏素质)均显著优于中步速组和低步速组,特别是医疗费支出也随着步速能力的提高呈现递减的趋势。可见,保持相对较高的步速能力,对提高老年人运动能力,降低医疗费支出有积极的作用。

In order to probe into the interrelations between walking pace and elderly people’s sports capacities and medical expenses,the authors made a study by basing their analysis subject on 590 national medical insurance paying elderly people older than 70（in Japan）,and by means of field investigation,measurement and mathematical statistics.By dynamically observing average medical expenses per month per person in 4 years,the authors found that 3 sports capacity indexes（lower limb muscle stretching power,balancing capacity,agility quality） of the elderly people in the high walking pace group were significantly better than those of the elderly people in the medium walking pace group and the low walking pacing group,especially,medical expenses showed a trend of decreasing as the walking pace capacity increased.Therefore,maintaining a relatively high walking pace capacity plays a positive role in boosting elderly people’s sports capacities and reducing their medical expenses.
