AbstractBACKGROUND: The current study was designed to examine the effect of 12 weeks of resistance training on strength and functional ability in 10 medically stable hemodialysis patients (age, 42.8 4.4 years). METHODS: Subjects were tested on four separate occasions, each separated by 6 weeks. The first (T1) and second tests (T2) were controls with no exercise intervention between them. T3 followed 6 weeks of resistance training, and T4 occurred after 12 weeks of training. Variables tested included percentage of body fat, distance covered in the 6-minute walk test, peak torque of quadriceps muscles of the dominant leg, maximal handgrip strength, normal and maximal walking speeds, and time to complete 10 repetitions of the sit-to-stand-to-sit test. Data were analyzed by means of a one-way repeated-measures analysis of variance procedure. RESULTS: Results indicate that after 12 weeks of training, there was a significant (P < 0.05) increase (12.7%) in peak torque at 90 degrees /s (139.1 19.3 nm) compared with T1 and T2 (mean, 124.1 18.7 [SEM]; 123.5 16.9 Nm), respectively. The distance covered during the 6-minute walk was increased ( approximately 5%; P < 0.05) compared with baseline (T1, 522.1 46.2 m; 521.9 48.5 m) after 6 weeks of training (548.3 52.1 m) and remained elevated at week 12 (546.5 54.2 m). Maximal walking speed was increased (P < 0.05) by week 12 (195.9 15.4 cm/s) compared with baseline (T1, 182.9 12.7; 185.5 13.0 cm/s). Time to complete 10 repetitions of the sit-to-stand-to-sit test decreased at 12 weeks (17.8 1.9 seconds) versus baseline (T1, 20.3 1.5 seconds; T2, 20.6 5.5 seconds). CONCLUSION: Resistance training can be used safely to increase strength and functional capacity in stable hemodialysis patients. Copyright 2002 by the National Kidney Foundation, Inc.
