本研究目的為探討運動訓練對尿毒血液透析患者心肺耐力與憂鬱狀態之成效。以立意取樣方式選取南部某醫學中心的血液透析患者共40位,按患者意願分成20位患者為運動訓練實驗組,20位患者為對照組。實驗組於非洗腎期進行每週三次,每次約30-50分鐘,為期八週的運動訓練。於運動訓練前和運動訓練第八週後兩組患者分別接受運動測試檢查以評估心肺耐力及填寫貝氏憂鬱量表。研究結果顯示運動訓練後患者之休息收縮壓減少5.6%、休息心跳率降低10.2%、最大攝氧率上升36.1%、無氧閾攝氧率增加17.5%、氧脈提昇20%、最大運動負荷量進步43.3%及憂鬱狀態分數下降36.2%,與對照組有顯著差異。由本研究發現透過運動訓練可增進血液透析患者之心肺耐力及減輕憂鬱狀態。因此,可建立慢性腎衰竭患者本土化之運動訓練模式,以改善臨床照護品質。
The purpose of the study was to explore the effects of exercise training on cardiopulmonary endurance and depression status of hemodialysis patients. The purposive sample was recruited from a medical center in southern Taiwan. A total of forty hemodialysis patients were assigned into the experimental and control groups. Twenty patients in the experimental group underwent a 30-50 minutes, three times a week, stationary bicycle training during off-dialysis period for eight weeks. Twenty patients in the control group did not receive any exercise. The exercise test was administered to measure the cardiopulmonary endurance and the Beck Depression Scale was used to evaluate the depression status of each patient prior to and after the 8-week exercise training. Results of the study showed that exercise training increased cardiopulmonary endurance and improved depression status. The resting systolic blood pressure and heart rate reduced by 5.6% and 10.2% respectively. The VO2max, anaerobic threshold VO2, O2 pulse and maximal workload increased by 36.1%, 17.5%, 20%, 43.3% respectively. The depression scores decreased by 36.2%. Significant difference was noted between the two groups. The findings may indicate implementing exercise training during an off-dialysis period can enhance the quality of clinical care for chronic renal failure patients .
