유산소성운동이 중년여성의 신체구성과 등속성근기능에 미치는 영향

Abstract

This study was conducted to examine the effects of the walk·running exercise programs on body composition and isokinetic muscular function in 30 middle-aged women. As a result of analysis, the following conclusion was drawn.

1. Body composition-related factors

1)As for the pre-test of such body composition as weight, %body fat, WHR, BMI, and LBM among groups, there was no difference between exercise group and control group, but some increase or decrease was shown in the post-test. As for the difference between pre-test and post-test, %body fat, WHR, and BMI showed some increase or decrease, suggesting the positive effect of aerobic exercise on body composition in middle-aged women, whereas there was no difference in all factors in the control group. As for the increase and decrease of change, the walk·running group had more effects than the walk group.

2. Isokinetic muscular function

1)In the extensor and flexor of 60˚/sec maximum muscular strength, the pre-test among groups showed no difference between exercise group and control group. On the other hand, the post-test showed a significant difference in extensor for exercise group and control group and in flexor for walk group and walk·running group. Also there was a significant difference in flexor(R) between pre-test and post-test.

2)In the extensor and flexor of 60˚/sec peak torque to body weight, while the pre-test among groups showed no difference between exercise group and control group, the post-test showed a significant difference in extensor(R) for control group and in extensor(L) for experiment group and control group. There was a significant difference in flexor(R) showed for control group and walk·running group and in flexor(L) for both experiment group and control group. There was a significant difference in flexor(R) between pre-test and post-test.

3)In the extensor and flexor of 180˚/sec maximum muscular strength, while the pre-test among groups showed no difference between exercise group and control group, the post-test showed a significant difference in extensor(R) for walk·running group. There was a significant difference in extensor(L) between control group and walk·running group. There was a significant difference in flexor(R) for both exercise group and control group, and in flexor(L) for exercise group. There was a significant difference in extensor(R) and flexor(R, L) between pre-test and post-test.

4)In the extensor and flexor of 180˚/sec peak torque to body weight, while the pre-test among groups showed no difference between exercise group and control group, the post-test showed a significant difference in extensor(R) for walk·running group. There was a significant difference in extensor(L) and flexor(R) for control group and walk·running group and in flexor(L) for exercise group. There was a significant difference in extensor and flexor between pre-test and post-test.
