Background: Exercise may be a therapeutic tool for improving the functional capacity in patients with chronic kidney disease (CKD) who are on hemodialysis (HD). Aim: To determine the effects on muscle strength (MS), functional capacity (FC) and quality of life related to health (QOLRH) of a resistance training program in patients with CKD on HD. Patients and methods: Thirteen CKD patients aged 38.8 ± 3 years, (7 men) on HD for more than one year participated in an exercise program twice a week during 8 weeks. At the beginning and at the end of the program, MS using a knee extension isometric strength test, FC using the six minutes walking test (6MWT) and QOLRH using the KDQOL CV-36 questionnaire were evaluated. Heart and respiratory rates, blood pressure, oxygen saturation and modified Borg scale were measured as control variables Results: After training, there were significant improvements in MS in both legs; in the distance travelled during 6MWT and in the physical component summary score of the KDQOL-36. Furthermore, a significant decline in diastolic blood pressure was observed. All other control variables did not change significantly. Conclusions: Exercise training during eight weeks in CKD patients in HD resulted in significant improvements in muscle strength, walking capacity and in the physical component of a quality of life score for patients with CKD.
