Effects of a Structured Physical Activity Program on Habitual Physical Activity and Body Composition in Patients With Chronic Kidney Disease and in Kidney Transplant Recipients

摘要

Objectives: In this study, we compared the effects of an individualized physical activity program on lifestyle, metabolic profile, body composition, and quality of life in kidney transplant recipients and patients with chronic kidney disease. Materials and Methods: Our study included 24 kidney transplant recipients and 15 patients with chronic kidney disease at stage 3/4. Body composition (impedance spectroscopy) and habitual physical activity (accelerometry) assessed at baseline were used to prepare the individualized physical activity program. Participants received repeated training, which was supervised during the first 2 weeks, followed by short message service reminders. Measurements were repeated after 1 and 3 months. Results: Time spent daily on physical activity and total energy expenditure increased in kidney transplant recipients (from 126 ?± 87 to 200 ?± 132 min/day [P = .001] and from 1.73 ?± 0.37 to 2.24 ?± 0.59 cal/min [P .001]) and in patients with chronic kidney disease (from 79 ?± 78 to 109?±114 min/day [P .001] and from 1.5 ?± 0.5 to 1.92 ?± 0.47 cal/min [P .001]). Adipose mass (40.8 ?± 11.5 vs 38.5 ?± 10.3 kg; P = .01), total body water (38.1 ?± 9.1 vs 37.3 ?± 9.7 L; P = .01), and fat tissue index (14.3 ?± 3.7 vs 13.5 ?± 3.1 kg/msup2/sup; P = .009) decreased significantly only in kidney transplant recipients. Body cell mass decreased in patients with chronic kidney disease. Significant changes of estimated glomerular filtration rates were observed in kidney transplant recipients. Conclusions: Increased physical activity achieved through structured exercise programs induced beneficial effects on metabolic profile and body composition in patients with chronic kidney disease, with even greater benefits in kidney transplant recipients.
