Figure 1

Typical data treatment for the physical activity bouts determination by different criteria. The illustration shows the MET values determined by an accelerometer from 18:40 to 19:10 in one of the participants (Sub #1). The boxes and lines above the illustrations indicating the physical activity bouts determined by the different criteria. The white box means physical activity > 3 METs lasting > 10-min without an interruption (10-min), the gray box means physical activity > 3 METs lasting > 10-min allowing a 1-min interruption (17-min), and the black box means physical activity > 3 METs lasting > 10-min allowing a 2-min interruption (22-min). The black lines sandwiched by the closed circle means physical activity lasting > 10-min without an interruption (14-min and 11-min), the black line sandwiched by the arrows means physical activity lasting > 10-min allowing a 1-min interruption (26-min), and the black line sandwiched by the squares means physical activity lasting > 10-min allowing a 2-min interruption (30-min).
