Linear mixed model fixed effect statistics demonstrating the relationship between sleep duration (TST) and night (pre-intervention vs. post-intervention) on cardiorespiratory parameters. Fixed effects determined to have a significant effect on the specified cardiorespiratory variable (α < 0.05) are in bold and denoted with an asterisk (*). (HR, heart rate; HRV, heart rate variability; night*TST, interaction between night and total sleep time; RR, respiration rate; TST, total sleep time).
