详细说明

A total of 120 adults with Chronic kidney disease (CKD) stages G1-G4 will participate in this randomized controlled trial to evaluate the effects and safety of different exercise modalities on renal function, physical function, and quality of life, and to explore potential mechanisms related to renal hemodynamics, inflammation, and oxidative stress. Participants will be randomly assigned to aerobic exercise, resistance exercise, combined exercise, or control groups, with 30 participants planned per group. The study will last 12 months, with assessments at baseline and months 2, 4, 6, and 12.<br> <br> Participants in the exercise groups will complete three approximately 60-minute sessions weekly, including at least one supervised in-person session and remotely monitored sessions. Aerobic exercise will target 55-80% of estimated maximum heart rate. Resistance exercise will use resistance bands and body weight, with intensity adjusted according to individual ability and perceived exertion. The combined group will perform two aerobic and one resistance session weekly. The control group will receive routine CKD health education without structured exercise training during the study.<br> <br> Primary outcomes include renal function and metabolic parameters. Secondary outcomes include physical function, body composition, and quality of life. Exploratory assessments will examine renal hemodynamics, inflammatory markers, oxidative stress, and fibrosis-related biomarkers. Exercise participation and adherence will be monitored, and adverse events will be recorded in all groups. Serious adverse events will be managed according to the study protocol and applicable ethics requirements.

武器和干预

参与者组/臂
干预/治疗
实验性的：Aerobic Exercise group

Participants assigned to this group will receive aerobic exercise training.
其他：Aerobic Exercise

Participants will undergo aerobic exercise training three times per week for 12 months, with each session lasting approximately 60 minutes. Training will consist primarily of aerobic movements, including high knees, half-squat jumping jacks, boxing steps, V-steps with arm movements, knee lifts with torso rotation, and jumping jacks. Exercise intensity will be targeted at 55%-80% of age-predicted maximum heart rate calculated using the Tanaka formula. Heart rate and session duration will be monitored using a Huawei fitness band. Exercise intensity and difficulty will be individually adjusted according to exercise tolerance and training performance. Progression may involve increasing exercise duration, movement speed, or exercise difficulty. Sessions will include 3-5 minutes of warm-up and 3-5 minutes of cool-down and stretching.
实验性的：Resistance Training group

Participants assigned to this group will receive resistance training.
其他：resistance training

Participants will undergo progressive resistance training three times per week for 12 months, with each session lasting approximately 60 minutes. Training will primarily use resistance bands and bodyweight exercises, including resistance-band chest presses, resistance-band rows, squats, and other exercises adapted to individual physical capacity. Resistance and exercise difficulty will be selected according to baseline exercise capacity and training experience. The target intensity will be adjusted using the rating of perceived exertion (RPE), with participants performing 10-15 repetitions to a level at which the exercise feels substantially effortful. Training will begin with lower resistance and fewer sets, with progressive increases in resistance or sets according to individual tolerance and performance. Exercise completion, resistance, repetitions, fatigue, and discomfort will be recorded throughout the intervention.
实验性的：Combined Exercise group

Participants assignedto this group will receive combined aerobic andresistance exercise training.
其他：Combined Exercise

Participants will undergo combined exercise training three times per week for 12 months, with each session lasting approximately 60 minutes. The weekly program will include two aerobic exercise sessions and one resistance exercise session. Aerobic training will use movements such as high knees, half-squat jumping jacks, boxing steps, V-steps with arm movements, knee lifts with torso rotation, and jumping jacks, with intensity targeted at 55%-80% of age-predicted maximum heart rate calculated using the Tanaka formula. Resistance training will use resistance bands and bodyweight exercises, with intensity adjusted according to the rating of perceived exertion (RPE) and individual exercise capacity. Exercise intensity and difficulty will be progressively adjusted according to tolerance and performance. Heart rate, session duration, exercise completion, and training-related discomfort will be monitored and recorded.
无干预：control group

Participants received conventional health education.
