Effects of exercise and anabolic steroids on total and lipoprotein @entity165 concentrations in male and female XXXX .

@entity35 @entity134 @entity165 @entity5420
Forty male and 40 female @entity35 were randomly assigned to 1 of 4 experimental groups. Half of the animals of each gender were exercised by jumping (weighted by a vest with up to 70% body weight) to a height of 16 cm 20 times X d-1 (30 s between jumps) 5 d X wk-1 for 8 wk. Half of the exercised animals and half of the sedentary animals were injected with the anabolic @entity134 durabolin (0.2 mg in 0.1 ml @entity5420 seed oil) 6 d X wk-1 for the last 3 wk of the 8-wk exercise program. The other animals were injected with 0.1 ml of @entity5420 seed oil (as a placebo) on the same schedule. At the end of the 8-wk program, blood was drawn from the right atria of the anesthetized animals. Plasmas were analyzed for total @entity165 (TC) and high density lipoprotein @entity165 (HDL-C) concentrations. Low density lipoprotein @entity165 (LDL-C) concentration was estimated as the difference between these two parameters (TC - HDL-C). A three-factor analysis of variance (2 X 2 X 2) demonstrated that there was a significant (P less than 0.05) gender effect (males greater than females), but no @entity134 or exercise main effects for TC. There were significant (P less than 0.05) @entity134 and exercise main effects for both HDL-C and estimated LDL-C, as well as a significant gender main effect for estimated LDL-C (but not HDL-C).(ABSTRACT TRUNCATED AT 250 WORDS)
