Effect of Online Home-Based Training on Functional Capacity and Strength in Two CKD Patients: A Case Study

chronic kidney disease (CKD) is a clinical condition characterized by the loss of kidney function over time, as well as several complications affecting gastrointestinal, cardiovascular, and musculoskeletal systems. physical exercise seems to induce positive adaptations in CKD patients, without side effects. usually, these patients show a reduced physical activity and physical performance. the aim of this case-report was to evaluate the effects of an online training protocol on functional capacity and on muscle mass, in CKD stage III patients. methods: Two CKD (stage III according to KDIGO guidelines) participants (1 female, patient A; 1 male, patient B) were enrolled and they performed an online tailored-supervised combined training lasting 12 weeks, including multi-joint strength exercises using thera band and an aerobic session at 65-70% of the patients' heart rate reserve. Results: Both patients showed an improving trend on functional capacity (6 min walking test: patient A = +3%; patient B = +5.3%) and on strength of the upper arms (handgrip strength test-right: patient A = +13.4%; patient B = +19.1%; handgrip strength test-left: patient A = +42.8%; patient B= +12.9%), as well as a reduction in inflammation and oxidative stress biomarkers. the protocol was feasible, and no side effects were evidenced. these case studies suggest that the online combined training can produce beneficial effects in CKD patients under conservative therapy, by reducing the CKD-related complications and improving the adherence to exercise of this population of patients, overcoming logistic barriers such as transportation, availability of facilities, and working and personal-life schedule.
