[Effects of a resistance training program in patients with chronic kidney disease on hemodialysis].
BACKGROUND
Exercise may be a therapeutic tool for improving the functional capacity in patients with chronic kidney disease (CKD) who are on hemodialysis (HD).


OBJECTIVE
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.


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.
