| eta endorphin (B-E) infusion during exercise has been shown to attenuate blood glucose, lower insulin and increase glucagon. The effects of B-E infusion during exercise on plasma lactate, catecholamine, corticosterone and lipids is unclear. Therefore, this study was designed to examine the effects of B-E infusion on plasma glucose, lactate (LA), epinephrine (EPI), norepinephrine (NE), corticosterone (CORT), free fatty acids (FFA) and triglycerides (TG) at rest and exercise. Forty untrained Sprague-Dawley rats (250-275 grams) were randomly assigned to one of four groups (n = 10 rats/group): (1) 90 minutes of B-E infusion (0.5 ;A 2 x 2 ANOVA revealed significant main effects for B-E infusion (p... |
