Design outcomes

Primary

Measure	Time frame
1. Sedentary behavior measured objectively with accelerometers and a validated Portuguese version of the Physical Activity Questionnaire (PAQ) 2. Physical activity measured objectively with accelerometers and a validated Portuguese version of the Physical Activity Questionnaire (PAQ) 3. Cardiorespiratory fitness is assessed by the 20-meter multi-stage shuttle run test and by a multi-stage maximal bicycle ergometer test 4. Body composition is assessed by dual-energy X-ray absorptiometry (DXA) and by standard anthropometric procedures All primary outcomes are assessed at baseline and at the end of the intervention.	—
