Differential anabolic effects of testosterone and amino acid feeding in older men.Androgenic-anabolic steroids AAS anabolic effects synthetic derivatives of the male hormone testosterone. They can exert strong effects on the human body that may be beneficial for athletic performance. A review of the literature revealed that most laboratory studies did not investigate the anabolic effects doses of AAS currently abused in the field. Therefore, those studies trenbolone acetate kura not reflect the actual anabolic effects effects of steroids. The available scientific literature describes that short-term administration of these drugs by athletes effecs increase strength and bodyweight.
Anabolic Steroids: Mechanisms and Effects
One way of categorizing metabolic processes, whether at the cellular , organ or organism level, is as "anabolic" or as " catabolic ", which is the opposite and thus the separation of a macromolecule. Anabolism is powered by catabolism, where large molecules are broken down into smaller parts and then used up in cellular respiration. Many anabolic processes are powered by the hydrolysis of adenosine triphosphate ATP. Anabolic processes tend toward "building up" organs and tissues.
These processes produce growth and differentiation of cells and increase in body size, a process that involves synthesis of complex molecules.
Examples of anabolic processes include the growth and mineralization of bone and increases in muscle mass. Endocrinologists have traditionally classified hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The classic anabolic hormones are the anabolic steroids , which stimulate protein synthesis, muscle growth, and insulin. The balance between anabolism and catabolism is also regulated by circadian rhythms , with processes such as glucose metabolism fluctuating to match an animal's normal periods of activity throughout the day.
From Wikipedia, the free encyclopedia. This article is about anabolism and catabolisms as classifications of metabolism. For steroids with anabolic properties, see Anabolic steroid.
