Demographic data and physical activity
At all three measurement sessions—baseline week 0, post-test week 6, and post-test week 12—demographic and physical activity data were collected via a self-created questionnaire. The participants were asked how many minutes per week they performed moderate physical activities, vigorous physical activities, and strengthening exercises in the last 6 weeks. Furthermore, they were also asked how much they enjoy physical activity on a scale from 1 to 4 (1 = I do not enjoy physical activity; 4 = I enjoy physical activity very much).
