This study is a randomised controlled intervention trial for patients with chronic kidney disease who are on the waiting list for a kidney transplantation (n=200). The aim of this study is to test the effectiveness of intensive individual nutritional and exercise support combined with comprehensive rehabilitation before transplantation in comparison to a control group.

Patients are randomised to either the intervention or control group at the beginning of the study. Both groups are evaluated at the beginning after 6 months and after 12 months regarding their body composition, physical performance, blood values, quality of life and nutritional status. The control group only receives support via app during the study period (1 year), through which they receive detailed information about dialysis. In addition to access to the app, the intervention group receives individual recommendations for nutrition and exercise as well as a three-week inpatient rehabilitation.

Inclusion Criteria:

• Patients must be on dialysis
• Patients ≥ 18 years of age
• Patients who own a smartphone
• Patients must be willing to undergo inpatient rehabilitation within the project period
• signed informed consent and data protection regulation

Exclusion Criteria:

• Patients who are not psychologically or physically able to take part in exercise promotion measures and/or nutritional counselling as well as psychological offers
