Anxiety-related behaviors.

Experimental group	Open-arm time (%)	Closed-arm time (%)	Arm entries (number)	Fecal Bolus (number)
Normal sleep + sedentary	8.70 ± 1.17	70.17 ± 4.11	12.90 ± 1.47	1.80 ± 0.25
Normal sleep + exercise	19.63 ± 5.14*	66.03 ± 4.75	10.50 ± 0.60	1.90 ± 0.23
Sleep restriction + sedentary	14.07 ± 2.74	58.47 ± 4.67	10.60 ± 1.24	1.70 ± 0.26
Sleep restriction + exercise	17.43 ± 3.39	67.97 ± 2.86	11.40 ± 0.59	1.70 ± 0.21

Anxiety-related behavior data (Mean ± SE) occurring during the elevated-plus maze are presented after the 11-week experimental treatments. A main effect was found for exercise reducing the time spent in the open arms of the elevated plus maze. However, exercise significantly enhanced the percentage of time spent in the open arms of the elevated plus maze under normal sleep conditions but not sleep restriction conditions.

^(*)indicates differences between experimental group and normal sleeping sedentary controls. Significant differences were set at p < 0.05.
