Abstract
Patients with chronic renal failure are restricted in physical and social dimensions of life because of their treatment and their comorbid medical conditions. The aim of this study was to evaluate the effect of exercise training programs on functional work capacity, functional mobility, and quality of life in patients with renal failure on hemodialysis. Thirty patients with chronic renal failure on maintenance hemodialysis participated in a regular exercise training program three times per week for 12 weeks. Each exercise session consisted of warm up, cycle or treadmill exercises, stretching exercises, and cool down. All patients underwent the cardiovascular graded exercise tolerance test, the sit-to-stand-to-sit test, and the 6-min walk test. Questionnaires were used to assess the quality of life of the study group 1 week before and after the exercise training program. A total of 15 normal individuals who were age-matched and sex-matched with our patients were used as controls to compare the respiratory function. There was significant improvement in work capacity after the training exercise program compared with that before the program (from 7.24 ± 0.90 to 9.62 ± 1.1; P < 0.001); in addition, there was also a highly significant improvement in functional mobility. The quality of life was improved after the exercise training program according to four of five scales of 36 questionnaires. A suitable exercise training program is an important method for improvement of work capacity, mobility, psychological status, and quality of life.

(3) Forced expiratory flow between 25 and 75% of the vital capacity was slightly below normal in the dialysis patients (Tables 3 and 4). This table shows that the work capacity and functional mobility were improved after the exercise training program and that the difference between the results obtained before and after the program is highly statistically significant (P≤0.001)
The results of our study show that the quality of life improved after the exercise training program and that there is a high statistical significance in the first four scales of the KDQOL-36 questionnaire before and after exercise
Summary
Patients with chronic renal failure are restricted in physical and social dimensions of life because of their treatment and their comorbid medical conditions. Patients with chronic renal failure are restricted in physical, emotional, and social dimensions of life because of their treatment and their comorbid medical conditions. This reduction in physical functioning among patients with end-stage renal disease (ESRD) increases both the morbidity and the mortality. Psychosocial impairments, such as anxiety, depression, and poor quality of life, are common All these factors limit the patients’ functional capabilities [2]
