Physical Effects of Anabolic-androgenic Steroids in Healthy Exercising Adults: A Systematic Review and Meta-analysis.

Many athletes use assimilation androgen steroids (AAS) for physical strengthening, but the side effects associated with these increases are not strictly quantified. MEDLINE, EMBASE, Cochrane, SPORTDiscus, and PsycINFO were searched to determine a randomized, placebo-controlled study of AAS in healthy athletic adults. In this study, either muscle strength, body composition, cardiovascular durability or strength was reported. Two authors evaluated abstracts and decided on full-text search research, but these were examined in duplicate to determine the included research. The quality of the test was evaluated using the Cochran method. Data were doubly extracted using DerSimonian and Laird's random effect model and combined to calculate the improvement rate of the average results when possible. The pooled mean difference (SMD) of muscular strength between AAS and placebo was 0.27 (95% confidence interval, 0.07 to 0.47; I = 12.7%; 21 tests). The intensity of the AAS group was 52% greater than the strength of the placebo. The SMD of lean body mass change between AAS and placebo was 0.62 (95% confidence interval, 0.35 - 0.89; I = 26%; 14 trials). Because of the lack of data, we quantitatively summarized body fat mass, cardiovascular durability, efficacy and adverse reactions. Only 13 out of 25 studies reported adverse events such as increased low density lipoprotein (LDL), decreased high density lipoprotein (HDL), irritability, acne and so on. In healthy adults, the use of AAS is associated with an absolute increase in muscular strength and a slight increase in lean body mass. However, the transparency and integrity of adverse reaction reports varies, most trials are short-lived, and the doses tested may not reflect the actual use of the athlete.

Just because athletes and non-athletes acquire the same muscular strength, this does not mean that anabolic androgen steroids have no side effects (Harthens and Kuipers, 2004). Physical and psychological adverse side effects will affect long-term and short-term users of anabolic androgen steroids. They are athletes and non-athletes (Harthens and Kuipers, 2004). - People hear that nature is good every day, no. Treating the disease with Western medicine sounds a more serious side effect, but the fact is that Western medicine is more important than traditional Chinese medicine and Chinese medicine. Error labels are one of many problems with TCM.

Anabolic steroid hormones, also known as anabolic androgen steroids (AAS), are steroidal androgens, including natural androgens such as testosterone, and synthetic androgens with structurally related effects and testosterone. They are anabolic, in particular they increase intracellular proteins in skeletal muscle and also have varying degrees of androgen and masculinity, including the development and maintenance of positive secondary features such as facial and body hair growth. . The term anabolism means the anabolism of "thrown, mound" derived from Greek ἀναβο λήabab. Androgen or AAS is one of three types of sex hormone agonists, others are estrogen and progestogen like progesterone like estradiol

Anabolic steroid hormones were created to enhance the assimilation properties (tissue building) of androgens and to minimize the androgen (sexual linkage) properties. However, the absence of steroids eliminates the androgenic action, since so-called androgen action is actually anabolic in sexually relevant tissues. The effects of androgenic hormones on accessory gonads, reproductive organs and oily skin are the processes of anabolism in these tissues. The most potent anabolic steroid hormone is also the steroid with the greatest androgenic effect.

Anabolic steroid hormones were originally designed to specifically describe testosterone-derived steroids with important assimilation and male hormone effects of dissociation, but they are not related to all steroids based on the anabolic effect of AR agonists Even non-synthetic steroids like testosterone itself, how effective are androgens? Many anabolic steroid hormones have reduced androgens compared to anabolic potency, but anabolic steroid hormones are not just assimilation, so all anabolic steroid hormones retain androgens. In fact, since both types of effects are caused by the same signaling, complete dissociation of anabolic and androgenic effects may be fundamentally impossible. Receptor AR mediates. Therefore, the difference between the terms anabolic steroid and androgen is questionable and it is the basis for revised and more recent anabolic androgen steroids (AAS).
