Sleep-wake cycle parameters in the 8 h experiment

	Wake	NREM sleep	REM sleep	Total sleep
sd	91.41 ± 0.43*†‡	8.59 ± 0.44*†‡	0*†‡	8.59 + 0.44*†‡
CT1	51.24 ± 0.84	47.5 ± 1.04†	1.25 ± 0.2*	48.76 ± 0.84†
CT2	60.62 ± 3.1*	33.25 ± 2.78*‡	2.48 ± 0.76*	35.73 ± 3.28*‡

The table shows the percentage of time spent in the different stages of the sleep–wake cycle. CC, cage control group; SD, sleep deprivation group; CT1, control treadmill 1 group (15 min on/60 min off); CT2, control treadmill 2 group (30 min on/120 min off). Data are means ±s.e.m. for groups of 8 rats each.

^*P < 0.001 versus CC

^†P < 0.001 versus CT2

^‡P < 0.001 versus CT1. One-way ANOVA, followed by Bonferroni's post hoc test.
