초록
본 연구는 중년 남성들을 대상으로 3년간 1년에 1회씩 3차례에 걸쳐 운동부하 검사 시 심전도 반응을 측정하여 야외 및 트레드밀 걷기 운동 참여 여부에 따라 부하 심전도의 변화에 어떠한 양상이 나타나는지를 규명하고자, 안정 시 신체조성 분석, 운동부하 검사 시 심전도 반응을 측정하였다. 안정 시 신체조성 분석은 체지방율과 BMI를 측정하였고, 안정 시 및 운동부하 검사 시 심전도 반응은 ST/HR 경사 및 QRS 벡터를 측정하였는데, 그 결과는 다음과 같다. 1. ST/HR 경사의 변화에 있어서 운동 6분부터 통제 집단은 감소하기 시작하여 운동 9분과 peak시에
The purpose of this study was to investigate the changes of long term ECG response in a company with middle-aged male employees. Subjects were 60 men who were 40~55 years old. We enrolled 30 exercise group subjects into a 3-year exercise program. In measurement index, body composition was measured by % body fat and BMI. Exercise stress test analyses were measured using ST/HR slope and QRS vector. Statistical analysis was performed using analysis of repeated ANOVA. Results of this study were as follows: In ST/HR slope, the control group showed symptoms of ischemia after nine minutes of exercise. In the rest frontal axis of the QRS vector, the control group had a tendency towards right axis deviation. In the rest horizontal amplitude of the QRS vector, the control group had a tendency to show a significant decrease, but it was increased significantly in the exercise group. These findings suggest that inactive company workers was showed a decrease of exercise capacity, early diagnosis exercise-induced ST depression, and prolonged deviation of QRS vector, but that cardiac function could be elevated in active middle aged men through regular exercise program participation.
