Overview

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.
