In Exp. 1, rats were food-deprived for either 0, 1, 2, 3, or 4 days in a wheel or stabilimeter. Activity increased with deprivation for the wheel groups only, whereas blood glucose decreased in both conditions but significantly more for the wheel groups. Glucose was more highly related to weight loss than activity. In Exp. 2, groups were deprived in the wheels but prevented from running just prior to blood analysis. No short-term effect was observed; rather glucose changes were the same as found in Exp. 1. A possible relationship between glucose and activity is discussed. |
