BACKGROUND: Although the benefits of exercise for kidney transplant recipients (KTRs) have been widely demonstrated, these patients experience several barriers in undertaking a structured exercise program in hospital and non-hospital facilities.
AIM: To compare the effects of a supervised moderate-intensity gym-based intervention with a home-based low-intensity walking program on exercise capacity in KTRs.
METHODS: KTRs were asked to choose between two six-month programs. The first group performed a low-intensity interval walking intervention at home-based exercise intervention (HBex). The second group performed a supervised training program at an adapted physical activity gym (Sgym), including aerobic and resistance training. The outcomes, collected at baseline and at the end of the programs, included the 6-minute walking test, the peak oxygen consumption (VO2peak) during a treadmill test, the 5-time sit-to-stand test, and blood pressure.
RESULTS: Seventeen patients agreed to participate and self-selected into the HBex (n = 9) and Sgym (n = 8) groups. Two patients in the Sgym group dropped out because of familial problems. At baseline, patients in the HBex group were significantly older and had lower walking distance, VO2peak, and lower limb strength. Primary outcome changes were significantly greater in the HBex group than in the Sgym group (52 ± 23 m vs 8 ± 34; P = 0.005). No other significant differences between groups were observed. Both groups improved most of the outcomes in the within-group comparisons, with significant variations in VO2 peak.
CONCLUSION: Six-month moderate-intensity supervised or low-intensity home-based training programs effectively improved exercise capacity in KTRs. Gym-based programs combine aerobic and resistance training; however, in-home walking may be proposed for frail KTRs.
