海拔差异下的老年人体质特征比较研究

通过文献研究、数理统计等方法，对不同海拔地区老年人体质差异进行比较，探讨其内部的特征及规律。研究发现，高海拔地区老年人的身高、体重、围度、皮褶厚度以及体重指数均低于低海拔地区的老年人，肺活量、血压和安静脉搏与低海拔地区老年人有显著性差异，且收缩压值明显好于低海拔地区老年人；但综合身体素质却不及低海拔地区的老年人。

Comparative Study on the Physical Fitness Characteristics of Different Altitude among the Elderly

Through the methods of literature analysis,mathematical statistics and other methods,this article aims to explore the patterns and characteristics of the physical fitness of elderly people living in high-altitude regions through comparisons.The results show that the height,body weight,girth,skin-fold and BMI of elderly people in high-altitude regions are all lower than those in low-altitude regions;the vital capacity,blood pressure,static pulse of elder people in high-altitude regions have significant difference than those in low-altitude regions;and systolic pressure of high-altitude elderly people are obviously better,whereas their comprehensive body diathesis is less developed.
