“…Steroids are often used for rehabilitation purposes or to gain a competitive edge (Rogerson et al, 2007;Strauss 1990Total 1990 QUICK et al, 1985). The former is under the direction of a medical doctor whereas the latter is not.…”

“…Each news broadcast was coded to determine whether the news story addressed barriers of steroid use (SA = .93, K B & P = .86). Barriers were grouped into six subcategories: health costs, issues of illegality, drug testing, financial expenses of purchasing steroids, fines for steroid usage, and suspension for steroid usage (Denham, 2004b;Wilson & Schmidt, 2007) (Rogerson et al, 2007;Strauss et al, 1985). …”

“…At a cellular level, motor neurons react to testosterone by increasing soma size, dendritic length and synaptic input, and muscle cells respond to testosterone by increasing calcium channels [5] . When given exogenous testosterone, males had an increase in muscle size and/or in performance, both of which increased further if combined with resistance training [6][7][8][9][10][11][12] .…”

The hypothalamic-pituitary-gonadal (HPG) axis is essential for adequate responses to exercise and training both acutely and chronically. Both testosterone and estrogen play leading roles in neuromuscular adaptation to exercise in males and females. The purpose of this chapter is to illustrate the physiological and pathological changes that occur in the HPG axis secondary to exercise and training. In males, testosterone increases with acute bouts of exercise, but long-term effects are less clear, with evidence of lower testosterone in endurance athletes. Restricted energy availability may negatively affect hormone levels in male endurance athletes, but data regarding low energy availability and its impact on the HPG axis are limited in male athletes. Conversely, in females there is significant evidence that decreased energy availability inhibits the HPG axis, leading to menstrual irregularities and lower bone density. Hormonal changes secondary to acute bouts of exercise are more challenging to interpret in females due to menstrual variability, which traditionally has not been taken into account in many studies. However, some evidence supports an increase in testosterone and estradiol with acute exercise. More work is needed to elucidate the relationships among energy availability, basal hormonal fluctuations, and exercise, and their collective effects on the HPG axis.

“…The use of AAS for non medical purposes, such as improving body composition and image, increasing physical strength or assisting in recovery from injury, is controversial due to the potential adverse health effects and unfair performance advantage it offers [7,8]. Anabolic steroids have the potential to be of benefit to athletes in a wide variety of sports by increasing strength, power and body mass [6,22,59].…”

“…Consequently for years, the scientific community debated the utility of AAS, despite the fact that studies published had used inconsistent controls, insignificant doses and in some cases anecdotal reports [3]. However, recent studies that have been tightly controlled scientific investigations have shown that the use of certain AAS, namely nandrolone decanoate and testosterone enanthate does increase athletic performance by building muscle mass and strength [4][5][6][7][8].…”

Anabolic androgenic steroids effects on the immune system: a review

et al. 2009

View full text Add to dashboard Cite

Androgenic anabolic steroids (AAS) are synthetic derivatives of the male hormone testosterone. AAS are used by athletes and recreational users of all ages to enhance their athletic performance and/or physical appearance. While several adverse effects of AAS abuse have been described, their effect on the immune system has not been clearly elucidated. The literature generally indicates that supraphysiologic doses of AAS with an intact steroid nucleus are immunosuppressive, that is they reduce immune cell number and function. While those with alterations to the steroid nucleus are immunostimulatory as they induce the proliferation of T cells and other immune cells. Specifically, several common AAS have been shown to adversely influence lymphocyte differentiation and proliferation, antibody production, Natural Killer Cytotoxic activity and the production of certain cytokines, thereby altering the immune reaction. These effects may be profound and long lasting depending on the dosing regime, types or combinations of AAS used and the extent and duration of AAS abuse. Nevertheless, the effects of long term use of supraphysiologic doses of AAS on the immune system remain uncertain.
