Brief summary
To assess the efficacy of a 6-month lifestyle intervention in patients with end-stage renal disease(ESRD), we plan to conduct a self-controlled clinical trial. 34 participants receiving chronic HD will be enrolled. Each participant will go through three phases: 3-month control, 6-month intervention, and 3-month maintenance. No intervention will be performed in the control and maintenance phases. The lifestyle intervention will comprise care from a multidisciplinary team, including a nephrologist, nurse practitioner, physiatrist, and dietitian. The exercise training component is an in-hospital supervised training 2\ 3 times weekly for 6 months. Cyclic aerobic and resistance training will be performed. Assessment will be performed every three months and 5 times in total, including cardiopulmonary exercise testing, isokinetic quadriceps strength testing, hand grip strength, body composition analysis, Chinese Kidney Disease and Quality of Life questionnaire, self-recorded physical activity, and Mini Nutritional Assessment. The aim of this study is to assess the efficacy of a lifestyle intervention in patients with chronic kidney disease (CKD) on physical fitness, quality of life, and immunity. It is hypothesized that the lifestyle intervention will elicit a significant benefit in the aforementioned parameters and will last until the maintenance phase.
Detailed description
The prevalence of end-stage renal disease is high, especially in Taiwan. Cardiovascular diseases and infection are the major causes of morbidity. Though evidence is clear that exercise training in this population is beneficial to fitness、quality of life、morbidity, it is seriously underused. Poor physical fitness is known to associate with high-leveled systemic inflammation and immune dysregulation but the detailed relationship remains unclear in the ESRD population. Moreover, though exercise improves low physical fitness, available research concerning its effect on the pro-/anti-inflammatory immune response is scarce. Does supervised lifestyle intervention has the potential to improve physical fitness, and quality of life in patients receiving maintenance hemodialysis (HD)? To assess the efficacy of a 6-month lifestyle intervention in patients under HD, we plan to conduct a self-controlled clinical trial. No intervention will be performed in the control and maintenance phases. The lifestyle intervention will comprise care from a multidisciplinary team, including a nephrologist, nurse practitioner, physiatrist, and dietitian. The exercise training component is in-hospital supervise training 2\ 3 times weekly for 6 months. Cyclic aerobic and resistance training will be performed. Assessment will be performed every three months and 5 times in total, including cardiopulmonary exercise testing, isokinetic quadriceps strength testing, hand grip strength, body composition analysis, Chinese Kidney Disease and Quality of Life questionnaire, self-recorded physical activity, and Mini Nutritional Assessment. The aim of this study is to assess the efficacy of a lifestyle intervention in patients under HD on physical fitness, and quality of life. It is hypothesized that the lifestyle intervention will elicit a significant benefit in the aforementioned parameters and will last until the maintenance phase.
Interventions
Two options for the participants to choose from. First, a home-based program. The participant will be requested to wear a heart rate recorder during home exercise. Second, a hospital-based program. The participants visit the rehabilitation center twice weekly to receive supervised exercise therapy. The exercise prescription comprises aerobic and resistance training. The intensity is set initially at ventilatory anaerobic threshold and gradually titrated up to respiratory compensatory point based on the breath-by-breath cardiopulmonary exercise testing. The duration is 25\ 35 minutes per session plus a 5-minute warm-up and 5-min cool-down. The frequency is 2\ 3 sessions per week and about 70 sessions in total.

Participant flow
Recruitment details
Participants were eligible for inclusion if they had been undergoing hemodialysis (HD) for more than 3 months, were over 20 years of age, had adequate dialysis (Kt/V \> 1.2), obtained approval from their nephrologist, and were able to walk independently for more than 10 meters. Exclusion criteria included recent hyperkalemia, medical or orthopedic conditions, muscular or psychological disorders, and a history of heart failure or inability to participate in cycling or exercise testing.
Pre-assignment details
This study employed self-controlled design. Over the study period, each participant underwent assessments at five time points (T1, T2, T3, T4, and T5) with about 3 months between each time point. Between T1 and T2 was the control phase, the participants received usual medical care only. Between T2 and T4 was the training phase, exercise training and nutrition education were implemented. The T4-T5 follow-up phase monitored changes after training cessation with standard medical care only.
