BODY COMPOSITION & ANABOLIC STEROIDS
Medifit Education explains here, what are the effects of Anabolic steroids on body composition?
Animal studies investigating the effect of anabolic-androgenic steroids on body composition have shown increases in lean body mass, nitrogen retention and muscle growth in castrated males and normal females. The effects of anabolic-androgenic steroids on the body weights of normal, untrained, male animals, treadmill-trainedor isometrically-trained rats, or strength-trained monkeyshave been minimal to absent; however, the effects of steroids on animals undergoing heavy resistance training have not been adequately studied. Human males who are deficient in natural androgens by castration or other causes have shown significant increases in nitrogen retention and muscular development with anabolic-androgenic steroid therapy. Human males and females involved in experimental and therapeutic trials of anabolic steroids have shown increases in body weight.
EXPERIMENT STUDIES ON HUMANS:
A review spanning more than three decades of experimental studies in men found that body weight may increase by 2–5 kg as a result of short-term (<10 weeks) AAS use, which may be attributed mainly to an increase of lean mass. Animal studies also found that fat mass was reduced, but most studies in humans failed to elucidate significant fat mass decrements. The effects on lean body mass have been shown to be dose-dependent. Both muscle hypertrophy and the formation of new muscle fibers have been observed. The hydration of lean mass remains unaffected by AAS use, although small increments of blood volume cannot be ruled out.
In summary, anabolic-androgenic steroids can contribute to an increase in body weight in the lean mass compartment of the body. The amount of weight gained in the training studies has been small but statistically significant.
The majority of weight gained on a steroid cycle is from retention of cellular and extra cellular fluid. This is what many lifters will call “water bloat”. This initial water weight gain is beneficial up to a certain point. It provides extra nutrients to the muscles and increases their ability to contract by simply giving them more area to work in. The average weight gain on a steroid cycle ranges anywhere from five to twenty pounds. Let’s say a lifter has gone on a two month steroid cycle and gained a total body weight of twelve pounds. By monitoring body fat percentages, through body composition analysis, an athlete can keep an idea as to how much of what they gained is body fat. Although anabolic steroids can increase the body’s ability to mobilize and use fat stores, many athletes find that they go through an increase in body fat while on a bulking cycle. This is simply because they take in an excess amount of calories on an effective bulking program. This is actually a benefit, not a hindrance, at this time. Let’s say our subject who gained twelve pounds determined through body composition analysis that he had put on four pounds of body fat. This leaves an eight pound increase in lean body weight. Of that eight pounds, it is very likely that only two pounds are skeletal muscle. It is known that for every one pound of skeletal muscle you put on, the body brings with it three pounds of supportive cellular and extra cellular fluid. Still, an increase of two pounds of skeletal muscle mass is a substantial gain.
