Figure 2.

Differences in the time and frequency of physical activity bouts compared with those determined using a 4 sec epoch length. The Y-axis shows the differences between the time or the frequency spent on the physical activity bout determined by the 4 sec epoch length and that by the 20 sec or 60 sec epoch length, respectively. TPA3, TPA5, TPA10; total physical activity lasting longer than 3 min, 5 min and 10 min. MVPA3, MVPA5, MVPA10; moderate to vigorous intensity physical activity lasting longer than 3 min, 5 min and 10 min.
