2.2.4. Self-Reported Physical Activity

Physical activity was assessed via a single item from the Stages of Change for Exercise questionnaire [35,36], which measured participants' stage of change for increasing exercise. Participants were asked to respond to the question, 'Do you currently engage in regular physical activity?' The following instructions were included: 'For physical activity to be considered "regular" it must be done for 30 min at a time (or more) per day, and be done at least four days per week.' Additional information about how physical activity was defined can be found in the studies by Hellsten et al. [35] and Nigg [36]. The response options were 'Yes' and 'No'.
