FeelFit: High-intensity Interval Training to Improve Self-reported Physical Fitness in Brain Tumor Patients: a Randomized Controlled Trial

The FeelFit study aims to assess the effectiveness of High-Intensity Interval Training (HIIT) in improving self-reported physical fitness in adult brain tumor patients during periods of stable disease, as compared to a waiting-list control group. Furthermore, several secondary and exploratory outcomes will be evaluated. The study is part of the GRIP (GuaRding quality survivorshiP) project, which aims to improve quality of life in brain tumor patients.

Inclusion Criteria:

• reduced self-reported physical fitness;
• minimum age of 18 years;
• diagnosed with a primary brain tumor;
• stable disease, i.e. no signs of radiological or clinical tumor progression;
• no oncological treatment for at least two months prior to inclusion;
• able to speak, read and write in Dutch.

Exclusion Criteria:

• Karnofsky Performance Score < 70;
• already participated in a HIIT program < 1 month prior;
