목적: 본 연구의 목적은 운동심상 훈련이 심폐 기능에 미치는 효과를 확인하는 것이다. 방법: 본 연구는 20대 성인 남성 26명을 대상으로 실시하였다. 참가자는 각각 13명의 참가자를 고려하여 운동심상 훈련 군과 대조군으로 무작위로 할당되었다. 측정 방법으로는 트레드밀에서 심장부하 검사를 실시하였고, 최대산소섭취량, 운동 시간 및 회복 심박수를 측정하였다. 운동심상 훈련군은 일주일에 5번 운동심상 훈련을 적용하였다. 본 연구에서는 군 내 결과를 확인 하기 위하여 대응 t 검증을 하였고, 군간 비교를 위하여 독립 t검증을 실시하였다. 결과: 최대 산소 섭취량은 각 군의 전후 비교와 각 군 간의 비교에서 유의한 차이를 보였다. 운동심상 훈련군은 대조군에 비해 운동시간에 유의한 변화가 있었다. 회복 심박수에는 유의한 차이가 없었다. 결론: 본 연구에서는 운동심상 훈련군에서 최대산소섭취량 및 운동 시간을 개선하지만 회복 심박수에는 영향을 미치지 않는 것으로 나타났다. 따라서 운동심상 훈련은 심폐 기능 강화를 위한 프로그램으로 고려할 가치가 있다

Background: The oxygen uptake efficiency slope (OUES) is the most important index for accurately measuring cardiopulmonary function in patients with acute ischemic heart disease. However, the relationship between the OUES variables and important cardiopulmonary function parameters remain unelucidated for patients with acute ischemic heart disease, which accounts for the largest proportion of heart disease. Objects: The present cross sectional clinical study aimed to determine the multiple relationships among the cardiopulmonary function variables mentioned above in adults with acute ischemic heart disease. Methods: A convenience sample of 110 adult inpatients with ischemic heart disease (age: 57.4 ± 11.3 y; 95 males, 15 females) was enrolled at the hospital cardiac rehabilitation center. The correlation between the important cardiopulmonary function indicators including peak oxygen uptake (VO2 peak), minute ventilation (VE)/carbon dioxide production (VCO2) slope, heart rate recovery (HRR), and ejection fraction (EF) and OUES was confirmed. Results: This study showed that OUES was highly correlated with VO2 peak, VE/VCO2 slope, and HRR parameters. Conclusion: The OUES can be used as an accurate indicator for cardiopulmonary function. There are other factors that influence aerobic capacity besides EF, so there is no correlation with EF. Effective cardiopulmonary rehabilitation programs can be designed based on OUES during submaximal exercise in patients with acute ischemic heart disease.

This study examines the effects of a rehabilitation program on quality of life (QOL), cardiopulmonary function and fatigue during radiotherapy for breast cancer patients. The program includes aerobic exercise, stretching and strengthening exercises. Sixty-five women participated in this study and they were asked to perform supervised exercises that last for 60 minutes five times a week for six weeks. The European organization for research and treatment of cancer-cancer (EORTC QLQ-C30) and the breast (EORTC QLQ-BR23), predicted maximal volume of oxygen consumption () and fatigue severity scale (FSS) were assessed before and after the rehabilitation program. The 60-minute program consisted of a 10-minute warm-up, 30-minute of aerobic exercises, and 15-minute of strengthening exercises, followed by a five-minute cool-down. Heart rates were monitored throughout the exercise class to ensure that patients were exercising at the target heart rate of 40~75% of the age-adjusted heart rate maximum. There were statistically significant differences in the changes of physical function and cancer related symptoms in the EORTC QLQ-C30 and EORTC QLQ-BR23 (p<.05). There was a statistically significant improvement in the predicted (p<.05), although there were no significant differences in the FSS (p>.05). The results of our study suggest that a supervised rehabilitation program may benefit the physical aspects and QOL of patients receiving radiotherapy for breast cancer.
