Expected delays in aMT6s phase markers after 3 days of treatment. Compared to corresponding baseline phase we expect delays of 2.5 h the control group, 4.5 h with bright light alone and 7.5 h in the light + exercise + melatonin treatments. Shifts in the our two aMT6s phase markers, onset and acrophase, are expected to be equivalent and significantly correlated.
