Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Secondary outcomes include other evaluations of quality of life (SF-36, KDQOL-SF, EQ-5D), objective measures of physical functioning (aerobic capacity and muscle strength), level of physical activity, gain in adiposity (body fat percentage by bio-electrical impedance assessment, BMI, waist circumference), and cardiometabolic risk factors (blood pressure, lipids, glucose metabolism). Additionally it is planned to study data on renal function, medical history, medication, psychological factors (motivation, kinesiophobia, coping style), nutrition knowledge, nutrition intake, nutrition status, fatigue, work participation, process evaluation and cost-effectiveness.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The increase in body weight is mostly fat tissue and typically around 9-10 kg. Most of this weight gain (\~90%) occurs in the first year after transplantation. Recent data indicate that steroid avoidance could not prevent this early increase in adiposity. This warrants specific focus on lifestyle factors, i.e diet and physical activity. In the UMCG RTR cohort we found that a lack of physical activity was related to a worse cardiometabolic profile and was an independent predictor of mortality. Moreover, the substantial increase in fat massweight gain was strongly related to low physical activity, high intake of energy-dense drinks, low consumption of vegetables, to increased plasma triglycerides and the metabolic syndrome. The intake of salt and saturated fat was high and fibre intake was low, indicating dietary habits that deviate substantially from recommendations for a healthy diet. Thus, both physical activity and dietary habits are important targets for lifestyle intervention in RTR.
Lasting improvements in lifestyle are notoriously difficult to obtain, but in recent years substantial intervention expertise has been developed in other high risk groups including prediabetes. It is now established that for long term purposes, prevention of excessive weight gain is more effective than treatment of weight excess. Since in RTR most of the weight is gained in the first year after transplantation, prevention is a very promising approach. Moreover, data in prediabetes suggest that combined intervention targeting both diet and physical activity may be particularly effective to this purpose.
Therefore, our aim is to investigate the effects on quality of life by a combined diet-and-physical activity program in RTR in the first year after transplantation.
This randomized controlled intervention study will use a combined diet-and-physical activity approach. After hospital discharge for transplantation, 219 patients will be randomized to three either a control groups: one group, who will receive standard care, one group will be exposed to a 3-month exercise program followed by individual counselling and one group will be exposed to the exercise program + dietary or to intervention followed by individual counselling. The individual counselling is to consolidate the achieved improvements in diet and physical activity and will be provided until 15 months after inclusion. This counselling is based on theories of behavioural change and motivational interviewing. Daily physical activity is evaluated with a pedometer and dietary habits by questionnaires and food records.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Usual care
Patients assigned to the usual care group receive the standard medical care (usual care) during the 15 months lasting study period. Physical training does not form a part of the usual care of renal transplant and dialysis patients. After randomisation, patients assigned to the usual care group receive the advice to meet the 'Nederlandse Norm Gezond Bewegen (NNGB), i.e. the advice to perform 30 minutes of moderately intense physical activity at at least five but preferably all days of the week.
No interventions assigned to this group
Exercise intervention
The exercise intervention in this group is identical to the exercise-only group. Patients assigned to the exercise intervention participate in a 12 weeks lasting, intensive, standardized and supervised physical training program which consists of a combination of endurance and strength training. After completion of the training program, patients receive an individual sport- and physical activity advice and lifestyle coaching.

Exercise intervention and dietary advice
The exercise intervention in this group is identical to the exercise-only group. The nutritional intervention runs throughout the entire 15 month intervention. The nutritional intervention aims to critically discuss pre-transplantation nutritional habits, and to set goals for healthier, better quality nutrition to prevent over eating and weight gain. These goals are set together with the subject to facilitate an autonomy supportive coaching climate.During the dietary consults, special attention goes out to saturated fat intake, whole-wheat and high fibre foods, fruit and vegetable intake, dietary salt consumption, and the use of energy-rich beverages such as soda, dairy drinks and fruit juices.
