压缩式运动文胸静态与动态压力变化规律研究
|
摘要
选择10名年龄为(20±2)岁的女性为试验对象,采集试验对象穿着压缩式运动文胸在静止站立状态以及分别以2.5、5.0、7.5 km/h的速度在跑步机上运动时,运动文胸罩杯、下围、肩部及背部的静态压力和动态压力,对比分析运动文胸静态压力与动态压力变化规律及影响因素。结果表明,运动文胸的静态压力和动态压力的变化都存在一定的周期性,但周期性影响因素不同,静态压力变化主要受人体呼吸作用影响,动态压力变化主要受运动步态周期影响。
The static and dynamic pressure at bra cup, lower chest circumference, shoulder and back of compressed sports bra were collected from 10 women with the age of(20±2) years old standing still and walking or running on treadmill at the speed of 2.5, 5.0, 7.5 km/h. The changes of static pressure and dynamic pressure of compressed sports bra and their influencing factors were compared and analyzed. The results show that the changes of static pressure and dynamic pressure of the bra have periodicity, but the influence factors of periodicity are different. The static pressure is mainly affected by respiratory function, and the dynamic pressure is mainly affected by gait cycle.
