WT means waveform. Daily evolution of WT (black line) in the three different conditions (control: without PA; morning: with scheduled activity between 09:00 and 09:45; evening: with scheduled activity between 21:00 and 21:45 in the upper, middle and bottom part, respectively). The time of PA is marked with the grey bar and the averaged sleep pattern with the black area for all experimental subjects (n = 16). The data shown have been obtained by averaging all individual mean waveforms. All variables are expressed as mean ± SEM and the three signaled areas are awakening (from 8:30 to 12:00), postprandial (from 14:00 to 17:50) and to fall asleep (from 23:00 to 02:50) from left to right and represents those sections of the graph with significant differences (p<0.05). Note that the last 8 h of the figure (from 00:00 to 07:50) are repeated in terms of clarity.
