Motor activity (MA) by time period. Data are presented as mean ± standard error of the mean (SEM) of log-transformed total activity counts (24 h; dark diamonds); activity counts in the morning from 07:02 to 13:00 h (AM, dark circles); afternoon from 13:02 to 19:58 h (PM; dark squares); and night from 20:00 to 07:00 h (open triangles). Time scale was expressed as every 14-d averaged total intensity from period 1 (P1 = week 1 to 2) to 6 (P6 = week 11 to 12). Significant difference of least squares means compared with P1: *, P < 0.05.
