Abstract

INTRODUCTION
The purpose of this study was to verify effects of 12 weeks exercise on cardiopulmonary and muscular function in chronic obstructed pulmonary disease(COPD) patients.
METHOD
Subjects, who voluntarily participated in this study, were 31 chronic obstructed pulmonary disease patients men aged in the range of 40-80 years old. They were assigned to the mild group(=17) and the severe group(=14) to disease severity(FEV 1 ). All subjects were carried out aerobic and resistance exercise programs for 40 to 60 minutes a day, five times per week in the period of 12weeks. The aerobic exercise was carried out walking exercise and its intensity was increased step by step in the range of 60-70%VO 2 max. The resistance exercise was carried out elastic-band exercise and weight-bearing exercise. Resistance exercise intensity was increased step by step to the muscular function test results. Statistical analyses were performed using paired t-tests within group and analysis of covariance(ANCOVA) to compare means between two groups.
RESULT
There were no differences of VO 2 max of two groups between pre and post tests, but there was a significant difference(p=.001) of exercise effect between groups in ANCOVA. Significant lower values of HRmax(p=.029) of severe group and dyspnea scale(p=.044) of mild group between pre and post tests were founded, but there was significant difference of dyspnea scale(p=.013) only between groups. Improvement of leg fatigue scale(p=.010) in the severe group between pre and post tests but no difference between groups(p=.013). Treadmill walking endurance of two groups(p=.000) were enhanced and significantly different between groups(p=.025). Upper limbs muscular function(mild group; p=.004, severe group; p=.005) and lower limbs muscular function(mild group: p=.001, severe group: p=.010) were all enhanced in two groups. There was a marked improvement of the lower limbs muscular function of mild group(p=.046) in between groups comparison.
CONCLUSION
It was concluded that exercise training is effective to COPD patients and it is suggested that it is possibile its effect is different to disease severity(FEV 1 ) in cardiopulmonary function and muscular function.
