Conditions
Interventions
We conducted a 3-month exercise training program at a low or high intensity. Participants had to train 5 times per week and had to achieve 300 kcal per exercise session for a total of 1500 kcal/week.
a 14-day phase at the onset of the exercise intervention (wk 1, wk 2)
and a 7-day phase at the end of the 3-month exercise intervention (wk 12).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The following were assessed during 3 data collection phases - a 7 day baseline phase (1 month prior to the exercise intervention), a 14 day phase at the beginning of the intervention, and a 7 day phase at the end of the intervention (after 3 months): 1. Energy intake, assessed using lunch boxes and a food journal (according to McNeil et al., 2012) 2. Energy expenditure, assessed using doubly labelled water (according to Schoeller and van Santen, 1982). 3. Body composition, assessed using dual X-ray absorptiometry | — |
