What this Trial Is About
Researchers are evaluating a home-based exercise and physical activity program for adults who have recently received a kidney transplant. This study aims to understand how different exercise intensities affect physical fitness, heart health, gut microbiome characteristics, and quality of life in these patients. The trial also examines the cost-effectiveness and potential for implementing this program in everyday care. The research involves 147 new kidney transplant recipients from two Belgian transplant centers.
Participants are randomly assigned to one of three groups for six months of exercise training a low-intensity group doing flexibility and balance exercises LIT, a moderate-intensity group performing aerobic and strength training MIT, or a group starting with moderate intensity and moving to high-intensity aerobic training combined with moderate strength training MHIT. After this initial phase, the MIT and MHIT groups receive a personalized physical activity program to help maintain an active lifestyle. This includes motivational support, goal-setting, and self-monitoring. The exercise begins three months post-transplant, and the maintenance program starts six months later.
Throughout the study, participants will be followed for two years after their transplant. Researchers will measure changes in peak oxygen consumption a key measure of cardiorespiratory fitness at 6, 12, and 24 months. They will also assess muscle strength, motor fitness, body composition, cardiovascular health, gut microbiome, quality of life, safety, cost-effectiveness, and how well the program can be implemented. Evaluations will occur at multiple points up to two years after transplantation to understand both short- and long-term effects.

Screening
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Treatment
Duration - 6 months
Participants take part in a 6-month home-based exercise training program at varying intensities depending on their assigned group, including flexibility and balance exercises or moderate to high-intensity aerobic and strength training.
Weekly remote monitoring and periodic assessments
Post-treatment Physical Activity Intervention
Duration - Up to 18 months following the initial 6-month training
Following the exercise training, participants in the moderate and moderate-high intensity groups receive a personalized physical activity intervention using motivational techniques to support long-term physical activity maintenance.
Regular follow-up contacts with decreasing frequency over time
Follow-up
Duration - Up to 2 years post-transplantation
Participants are monitored for up to 2 years after transplantation to assess physical fitness, cardiovascular health, and other outcomes.
Assessments at 3, 6, 9, 12, and 24 months post-transplant
