I have only had a quick look, but I think that this is suss because of the VPA definition. The authors could show us the data vs. response to the questionnaire, in particular the columns for folks doing >5 episodes of high intensity exercise per week... but they don't and instead simply show the categories >1per week and <1 per week. This smells bad.
