Design outcomes

Primary

MeasureTime frame
1. VO2max measured using maximal incremental exercise tests 2. Body mass measured using standardized procedures (i.e., participants wore light clothing and were barefoot) on a weighing scale 3. Maximal fat oxidation measured using maximal incremental exercise tests 4. Blood pressure measured using an electronic sphygmomanometer 5 .Heart rate variability assessed using a 12-lead electrocardiogram (ECG) system 6.Stress measured using the 10-item Perceived Stress Scale (PSS-10) 7.Anxiety measured using the 7-item Generalized Anxiety Disorder Scale (GAD-7) 8. Depression measured using the 21-item Beck Depression Inventory-II (BDI-II) 9. Sleep quality measured using the Pittsburgh Sleep Quality Index (PSQI) 10. Health-related quality of life measured using the 36-Item Short Form Health Survey (SF-36) 11. Affective responses measured using the Feeling Scale (FS) during each exercise session throughout the 60-week intervention 12. Enjoyment measured using the Physical Activity Enjoyment Scale (PACES) and the Exercise Enjoyment Scale (EES0 during each exercise session throughout the 60-week intervention All assessments (1-10) were conducted at baseline and subsequently at 12-week intervals (i.e., baseline, weeks 12, 24, 36, 48, and 60) in a controlled laboratory environment.

Secondary

MeasureTime frame
1. Heart rate measured using the heart rate sensor during each exercise session throughout the 60-week intervention 2. Perceived exertion measured by the Borg Rating Of Perceived Exertion during each exercise session throughout the 60-week intervention
