Values are mean ± s.e.m. Sleep parameters n = 15 hormone and metabolic basal data n = 17.

^aValues are obtained from 7 days prior to BL and DL sessions. ^bValues represented the basal samples (T = −360 min) from each clinical session. Sleep parameters were analysed based on data obtained from sleep diaries and Actiwatch data. *P < 0.05.
