ABSTRACT
BACKGROUND/AIMS: Physical inactivity is common in patients with chronic kidney disease (CKD) and is an important modifiable risk factor for mortality, morbidity, and reduced quality of life. The present single-centre pilot study evaluated the possibility of performing structured physical exercise using a specific walking model, Fitwalking, in a population of patients with CKD and, according to the American College of Rheumatology guidelines, also in a population with immuno-rheumatological disease. METHODS: Patients were recruited from the nephrology, haemodialysis, peritoneal dialysis, transplantation, and immuno-rheumatology outpatient clinics. After general and functional clinical evaluation and exercise prescription at the Department of Sports Medicine, we performed scientifically proven tests on CKD (Six-minute walk test and Sit to stand test), before and after the Fitwalking technique training course, and again after 6 and 12 months, to evaluate its effectiveness and identify any critical issues. RESULTS: We enrolled 80 patients, (41 males, 51.2%), mean age 53±12 years; the clinical data showed statistically significant improvements in systolic, average, and differential blood pressure, average speed, and physical strength. Participants also adapted to muscle fatigue, experienced a reduction in BMI with stable lean mass and reduced fat mass, and reported improved perceptions of physical and mental health, and quality of life. CONCLUSION: All enrolled patients successfully completed the process. A specific prescription was used that provided health education and allowed for the implementation of structured physical activity that could be performed safely and independently even after the training period. The activity was sustainable thanks to the training of in-house medical and nursing staff, demonstrating that it is possible to overcome this type of barrier to physical activity in CKD and in immuno-rheumatological patients.
ABSTRACT
BACKGROUND AND AIMS: Despite the excellent long-term outcomes in liver transplant (LT) recipients, several medical complications related to lifestyle still represent an issue. This study examined the effects of a 12-month supervised aerobic and strength training program on the aerobic capacity, muscle strength, metabolic profile, liver function, and quality of life of a cohort of LT recipients. METHODS: LT recipients with stable liver function were assigned to interventional exercise (group A) or usual care (group B). Aerobic capacity, muscle strength, metabolic profile, liver and kidney function, and health-related quality of life were assessed at baseline and after 6 and 12 months. Group A attended supervised training sessions 3 times per week for 12 months. Group B received general recommendations about home-based exercise. RESULTS: Forty patients from 6 Italian LT centers were randomized. Twenty-nine (72.5%, men-to-women ratio 23:6, mean age, 52 ± 8 years) LT recipients completed the study. Baseline characteristics were similar between groups except for body mass index and time from LT. No episode of acute rejection nor increase of transaminases occurred. Maximum workload and body mass index increased in both groups over time, but fasting glucose significantly decreased in group A (94.0 ± 15.0 mg/dL vs 90.0 ± 17.0 mg/dL; P = .037) and increased in controls (95.0 ± 24.0 mg/dL vs 102.0 ± 34.0 mg/dL, P = .04). Upper limb muscle strength increased only in supervised LT recipients. Vitality and general and mental health domains significantly improved after physical exercise. CONCLUSIONS: Supervised combined training was safe and effective in increasing aerobic capacity, muscle strength, and quality of life and in improving glucose metabolism in stable LT recipients.
