Observational
OtherThe reliability was determined (n=100) by filling out the mBQ, two times, one week apart (test-retest).
For validation (n=45), the scores between the modified Baecke Questionnaire and the International Physical Activity Questionnaire were compared and the correlation between the modified Baecke Questionnaire and VO2max(via Astrand-Rhyming Cycle Ergometer Test) and between mBQ and interview (via METS) were assessed.
