The purpose of the present study was to evalute exercise capacity and to investigate the possible introduction of supervised outdoor physical training for chronic hemodialysis (HD) patients. Twenty-four stable HD patients were used as subjects. They attempted to walk a distance of 8075m outside. Before commencing the exercise program, they received a hematological examination, an exercise stress test and an echocardiographsic examination. During the walk their oxygen consumption and number of steps were measured. In addition, walk-induced complications were inquired about after the exercise program. The results obtained were as follows: Ten HD patients completed the walk (C Group), but fourteen HD patients did not (I Group). All patients performed a significant amount of exercise (average=distance walked: 6660m: steps taken: 12704.7: calories burned: 675.4kcal), however their average exercise intensity was rather low (3.25Mets). Distance walked and energy consumed were significantly correlated with maximal oxygen uptake. The mean age of the C Group was significantly higher than the I Group. Many male patients, workers and trained patients completed the walk. Stroke volumes in the C Group were clustered around a mean value of 82.7ml, whereas in the I Group they were dispersed to above 100ml and below 80ml. There were no significant differences between the C Group and the I Group in hematological findings. A total of 20 patients who cooperated were examined using the exercise stress test. Six of these were found to have abnormal electrocardiographic results or abnormal blood pressure response. Untrained patients had pain in their foot joints or muscles after the exercise program. In conclusion, the present observations suggest that supervised outdoor physical training is beneficial to HD patients.
