The POWER-study is a two-arm exercise intervention study for pediatric patients following acute cancer treatment. This clinical trial will investigate the effects of a 12-week moderate to high-intensity exercise program on cardiorespiratory fitness in children and adolescents beginning 6 weeks after completion of acute cancer treatment.
The main objective of the POWER study is to investigate the effects of a 12-week moderate to high-intensity, partially supervised exercise program on cardiorespiratory fitness (VO2peak) in children and adolescents who have completed acute cancer treatment. This randomized controlled trial will include n=56 patients. Patients will be randomly assigned to the intervention or the control group. Patients in the intervention group will perform two supervised exercise sessions per week, one personal training session and one group-based training session. During an initial consultation, both groups receive recommendations for individual physical activity goals and a brochure with exercise recommendations as well as a fitness tracker to monitor their daily physical activity. Only the intervention group will receive daily activity targets, which will be adjusted on a regular basis. The study starts 6 weeks after completion of the patient's acute cancer treatment. Secondary aims of this interventional study are to evaluate additional performance markers, including muscle strength, functional mobility, balance, body composition and patient-reported outcomes including QoL, fatigue, and cognitive function as well as blood markers to evaluate changes in metabolic, immune, and heart health.

RECRUITINGChange in maximal oxygen uptake (VO2peak, ml/kg/min) from Baseline to T1 (end of intervention/12-weeks post randomization) between the two study groups, assessed in a maximal incremental exercise test (CPET) on a bicycle ergometer.
CPET is performed on an electronically braked cycle ergometer (Ergoline ergoselect 150 P) following the GDPK-Ergometry-Protocol). Ventilation and gas exchange data are determined breath-by-breath (Geratherm Respiratory Ergostik). VO2 peak is defined as the highest mean over 60 s and expressed on milliliters/kilogram/minute (ml/kg/min).
Time frame: At Baseline T0: 6 weeks following acute cancer treatment, T1: after 12 weeks of intervention, T2 (Follow up): after 12 weeks after end of intervention = 24 weeks after study inclusion
Adverse events
Time frame: At Baseline T0: 6 weeks following acute cancer treatment, T1: after 12 weeks of intervention, T2 (Follow up): after 12 weeks after end of intervention = 24 weeks after study inclusion
Muscle strength
Change in maximal muscle strength (CITEC handheld dynamometer; expressed in Newton), balance (single leg stance; expressed in seconds), functional mobility (TUG 3m; expressed in seconds), and body composition (Data Input Nutribox) between both study arms from T0 to T1, T0 to T2 and T1 to T2
Time frame: At Baseline T0: 6 weeks following acute cancer treatment, T1: after 12 weeks of intervention, T2 (Follow up): after 12 weeks after end of intervention = 24 weeks after study inclusion
Functional mobility
Time (in sec) to complete the Timed Up and Go Test (TUG). The participants perform one test trial. The time of standing up, walking at a safe and comfortable pace to a mark 3 meters away from them, returning to the chair and sitting back down is recorded.
Time frame: At Baseline T0: 6 weeks following acute cancer treatment, T1: after 12 weeks of intervention, T2 (Follow up): after 12 weeks after end of intervention = 24 weeks after study inclusion

Time frame: At Baseline T0: 6 weeks following acute cancer treatment, T1: after 12 weeks of intervention, T2 (Follow up): after 12 weeks after end of intervention = 24 weeks after study inclusion
Body Composition
Body composition is assessed by bioimpedance analysis. Whole body resistance and reactance are measured using the BIA device Data Input Nutribox.
