Brief summary

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.

Interventions

OTHERHigh-Intensity Interval Training (HIIT)

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.

Design outcomes

Primary

MeasureTime frameDescription
Self-reported physical fitnessBaseline 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.

Secondary

MeasureTime frameDescription
Self-reported fitnessBaseline 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.
VO2maxBaseline versus post-intervention (12 weeks)Physical fitness defined as the maximal oxygen uptake measured with a cardiopulmonary exercise test.

Other

MeasureTime frameDescription
Self-efficacyBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Exercise Self-Efficacy Scale (ESES), consisting of 10 questions on a 4-point scale. A higher score indicates higher exercise self-efficacy.
MasteryBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Pearlin Mastery Scale (PMS), consisting of 7 items on a 4-point scale.
Brain tumor specific quality of life questionnaireBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-BN20, specific for brain tumor patients.
Subjective HappinessBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Subjective Happiness Scale (SHS), consisting of 4 questions on a 7-point scale.
Subjective cognitive functioningBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Functional Assessment of Cancer Therapy - Cognitive Function (FACT-Cog), consisting of 37 items on a 5-point scale. A higher score means better cognitive functioning.
Subjective cognitive failureBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Cognitive Failure Questionnaire (CFQ), consisting of 25 items on a 5-point scale. A higher score refers to more cognitive errors.
Fatigue questionnaireBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Checklist Individual Strength (CIS20), consisting of measurements of fatigue severity, concentration problems, reduced motivation, and reduced activity.
Sleep questionnaireBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Pittsburg Sleep Quality Index (PSQI) assesses sleep dysfunction over 1-month interval.
Daily physical activityBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)International Physical Activity Questionnaire (IPAQ). A higher score corresponds to a physically more intense activity.
Self-reported depression questionnaireBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Beck Depression Index (BDI-PC), consisting of 21 questions on a 4-point scale.
Depression questionnaireBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)The Center for Epidemiologic Studies Depression questionnaire, consisting of twenty questions regarding symptoms of depression on a 4-point scale.
Muscle strengthBaseline versus post-intervention (12 weeks)Hand-held dynamometer
Subjective physical fitnessBaseline versus post-intervention (12 weeks)FitMax questionnaire, consisting of thee questions about the maximum capacity of walking, climbing, and cycling, estimating the VO2max.
Objective neurocognitive functioningBaseline versus post-intervention (12 weeks)Neuropsychological assessment (NPA), assessing different brain functions.
Objective neurological functioningBaseline versus post-intervention (12 weeks)Neurological assessment in neuro-oncology scale (NANO). A quantitative evaluation of 9 relevant neurologic domains.
Brain imaging (optional)Baseline versus post-intervention (12 weeks)MRI (magnetic resonance imaging)
Brain activity (optional)Baseline versus post-intervention (12 weeks)MEG (magnetoencephalography)
Anxiety questionnaireBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Beck Anxiety Index (BAI), consisting of 21 questions on a 4-point scale.
Health-related quality of life questionnaireBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC-QLQ\_C30) consists of 30 items and includes five functional scales, three symptom scales, a global health status/quality of life scale, and several single items assessing additional symptoms. The subscales are scored from 0-100 with higher scores representing better quality of life, better functioning, or a higher symptom burden.
Perceived functional impairmentsBaseline versus post-intervention (12 weeks) and versus follow-up (12 weeks and 6 weeks follow-up)Work and Social Adjustment Scale (WSAS), consisting of 5 questions on a 8-point scale.
