Design outcomes

Primary

Measure	Time frame
Efficacy of guided exercise on fitness and weight control: physical fitness and body composition (HRV, gut microbiota, Max VO2, fat mass, lean mass) - 1. Daily physical activity and a diet diary will be assessed at baseline, every week during the intervention, at follow-up point 2, and every week during the long term intervention until follow-up point 3 2. Anthropometry and blood pressure will be measured at baseline, half-way through the long-term intervention and at follow-up points 1, 2 and 3. Blood samples will also be taken at this point. 3. Body composition, and the 10-metre walking test will be measured at baseline and every two weeks through the short term intervention until follow-up point 1, and at follow-up point 2, halfway-way through the long term intervention and at follow-up point 3. The treadmill test will also be taken at all of these points apart from follow-up point 3. 4. Faecal samples, basal metabolic rate and max VO2 will be measured at baseline and follow-up points 1, 2 and 3	—

Secondary

Measure	Time frame
Maintenance of exercise and weight control intervention: 1. How many people will maintain their physical activity and weight control after a short intervention? 2. What are the reasons for people stopping exercise and weight control after a short intervention? 3. Does long-term guided exercise and weight control intervention help to maintain peoples LTPA and weight control after intervention?	—
