本研究目的在探討冠狀動脈疾病病人，經十二週有氧運動訓練後，其運動行為（運動強度、出席率）對運動成效（焦慮、憂鬱、疲憊之感受、心肺功能、以及生活品質）之影響。十二週有氧運動訓練計劃為每週三次，每次一小時。每次訓練包括5－10分軟身運動、運動跑步機上行走30分、5－10分的冷卻運動。研究工具包括狀態－特質焦慮量表、憂鬱量表、疲憊量表、36項短型生活品質量表。心肺功能是透過運動跑步機來測定。所有運動成效變項，分別於運動訓練開始前和結束後各測量一次。運動強度和出席率分別於運動訓練後第四、八、十二週各測量一次。研究結果顯示，出席率是決定生活品質改善最重要的因素。相反的，運動強度是決定最大攝氧量改變的主要因素。因此，護理人員應鼓勵病人維持一週三次的運動量和適當的運動強度，以協助病人從運動訓練中獲得最大的助益。

　　　　　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/Stamina 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 improvement in VO2max than is compliance rate. Nursing interventions should be directed toward increasing patients' compliance rate and exercise intensity to improve the exercise outcomes.
