Effects of exercise and fluoxetine on circulating corticosterone. Rats remained sedentary or were allowed 6 weeks of voluntary access to running wheels prior to receiving a single injection of either saline or fluoxetine (10 mg/kg). One hour after fluoxetine administration, rats were sacrificed, and trunk blood was collected for analysis of plasma corticosterone. Data represent means ± SEM. Asterisks p<0.05 relative to saline-treated groups. Numbers in each bar represent the number of rats included in that group
