[Anabolic steroids: damages, effect on performance, and on metabolism (author's transl)].
10 normal persons (age: x=22 years) and 15 weight lifters (age: x=27 years) were studied before and three months after taking Nandrolone danoate (ND). Strength exercises, hear rate during ergometer work, physical working capacity and certain biochemical variables were measured in the experimental group, as well as in a controll group of 7 weight lifters. Six weight lifters in the experimental group who had been taking ND for at least 3 years were also studied to determine whether there were any deleterious effects on their health. In addition, 75 athletes who had been taking anabolic steroids were investigated to determine the possible effects. It was found that: 1. In spite of an 7% increase in performance, the maximal heart rate was not higher when the subjects took ND. During submaximal work loads the heart rate (p less than 0.025) and the blood lactate level (p less than 0.05) were lower. During physical work, there was essentially no effect of ND on glucose or total lipids in serum. 2. The results from the three-months study, from the weight lifters taking ND for 3 years, as well as from 26 of the 57 athletes who had been taking ND showed no evidence of a deleterious effect of ND (based on 26 biochemical measurements). It would appear, therefore, that the general suggestion of a detrimental effect of anabolic hormones is not justified. 3. Damages or functional disturbances were found in 31 athletes and 3 weight lifters of the experimental group after oral application of anabolic alkyl-steroids. After a period of time without alkyl-steroid administration, all investigated biochemical parameters returned to normal levels; thus it appears that the aforementioned pathological findings are reversible changes in liver function.
