冠狀動脈疾病病人運動行爲與運動成效相關性之探討

The purpose of this study was to examine the impact of exercise behavior (compliance rate and exercise intensity) on exercise outcomes (maximal oxygen uptake, anxiety, depression, fatigue, and quality of life) after a 12-week exercise training program. The exercise training program consisted of a warm-up period, aerobic exercise period, and a cool-down period, three days a week for 12 weeks. Maximal oxygen uptake (VO2max), anxiety, depression, fatigue, and quality of life (QOL) were measured by means of graded exercise test with Bruce protocol, the State-Trait Anxiety inventory, the Center for Epidemiologic Studies Depression Scale, the Fatigue/Stansina Scale, and the 36-Item Short-Form, respectively. All exercise Outcome variables were assessed prior to exercise training and after 12 weeks of training. Compliance rate and exercise intensity were computed at the 4th, 8th and 12th weeks of training. Results of the study demonstrated that compliance rate is a more dominant predictor of the improvement in QOL than is exercise intensity. In contrast, exercise intensity is a more dominant predictor of improvment in VO2max than is compliance rate. Nursing interventions should be directed toward increasing patients' compliance rate and exercise intensity to improve the exercise outcomes.
