Abstract

Background: Physical rehabilitation is an important segment in the treatment of hemodialysis patients as they often have numerous comorbidities, functional constraints and severe disabilities resulting from physical inactivity.

Aim: To determine the effect of strength training program on muscle mass in patients on hemodialysis.

Methodology: The study was organized in the Center for Hemodialysis, Kosovska Mitrovica, Serbia for the duration of 8 weeks. It involved 25 patients, 18 (72%) men and 7 (28%) women, of average age 52.9 ± 14 years, who had received chronic hemodialysis for 3 x 3-4 hours for at least 3 months using commercially available dialysers. During the first two hemodialyses, twice a week for 15-20 minutes, exercises were performed with a load to increase muscle mass of the upper and lower extremities together with isometric muscle contractions to strengthen the quadriceps, as well as a lateral flexion of the spinal column. Measurements were made before and after exercise. Routine laboratory analyses, oxygen saturation, demographic, anthropomet- ric and clinical characteristics of the subjects were also evaluated.

Results: After exercise oxygen saturation (p = 0.04) and venous pressure (p = 0.009) were significantly lower than pre- exercise values. Muscle strength of the fist (p = 0.001), the upper arm (p = 0.005) and forearms (p <0.001) also differed signifi- cantly before and after exercise. After exercise lower extremity muscles were significantly stronger, both in relation to the left and right muscles of the shin and thighs. Left side (p = 0.002) and right-side (p = 0.017) spinal column flexion was significantly high- er after exercise.

Conclusion: The study confirmed the positive effect of strength training program on the size of the exercising muscles, lat- eral flexion of the spinal column and venous pressure.
