FeelFit: High-intensity Interval Training to Improve Self-reported Physical Fitness in Brain Tumor Patients (FeelFit)

April 2, 2025 updated by: Linda Douw, Amsterdam UMC, location VUmc

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: HIIT

The intervention group will perform High-Intensity Interval Training (HIIT), consisting of two supervised exercise sessions per week on a stationary bike, for 12 weeks.

In addition, participants will receive information on general guidelines for weekly physical activity levels and will be asked to keep an exercise diary.

Individualized High-Intensity Interval Training (HIIT) program with two exercise sessions per week for 12 weeks. The exercise sessions will be conducted on a stationary bike, with intensity tailored to each participant's maximum exercise capacity.
No Intervention: Waiting-list

The control group on the waiting list will be given the option to perform High-Intensity Interval Training (HIIT) after their participation in the study.

In addition, also participants from the waiting-list control group will receive information on general guidelines for weekly physical activity levels and will be asked to keep an exercise diary.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Self-reported physical fitness
Time Frame: Baseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)
Self-reported physical fitness is measured using the first question of the International Fitness Scale (IFIS) on general physical fitness, on a 5-point scale where a higher score corresponds to better self-reported physical fitness.
Baseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Self-reported fitness
Time Frame: Baseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)
In addition to the first question of the International Fitness Scale (IFIS), the other questions about cardiorespiratory fitness, muscle strength, speed and flexibility will also be asked as secondary outcomes.
Baseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)
VO2max
Time Frame: Baseline versus post-intervention (12 weeks)
Physical fitness defined as the maximal oxygen uptake measured with a cardiopulmonary exercise test.
