Steroids In SportsThe use of performance enhancing drugs is by no means perfformance new to athletics or even to society in general. The modern medical and scientific advantages to the use of performance enhancing anabolic steroids on sports performance have merely changed the methods and manner by which athletes utilize substances to enhance performance, making it all more efficient and effective — an exact science. But the use of these substances are nothing new to us, and this can easily be seen by looking back into ancient history as far back as several anabolic steroids on sports performance years ago. The very first use of anabolic steroids in sports sterids athletics can be dated back almost two thousand years in anabolic steroids on sports performance Greece. Other instances of anabolic steroid use have occurred throughout history, notably in ancient Rome as well, but none was more prevalent than in the ancient Greek Olympic Games. Well documented historical records state that sportw was prior to and during the ancient Greek Olympic Games that these ancient athletes would consume massive quantities of sheep and bull testicles . The end result was a vast increase in performance, specifically sportts the areas of what to take with dbol pills, speed, and muscular size.
Steroids In Sports - Steroid Abuse
Efforts to limit the androgenic while enhancing the anabolic effects have not been successful. Alterations to the structure of testosterone, so as to improve the pharmacokinetics of AS, have resulted in drugs, which are orally active, have a longer plasma half life and may be administered as depot injections.
Therapeutic doses of AS produce statistically significant effects on strength and athletic performance in well-controlled scientific and clinical trials. At low, therapeutic doses, diet and an intensive training regime are equally important in producing a statistically significant increase in strength. Higher doses 6—mg per week are regularly administered in sport and produce the greatest increases in muscle strength erythropoiesis and lean body mass. Patterns of steroid abuse can be complex, reflecting a desire to minimise side effects, and avoid detection.
AS side effects are of many types. AS increase salt and water retention leading to an expansion of the blood volume, but effects of steroids on blood pressure are equivocal and most cardiovascular side effects appear to be reversible.
Though these effects are reversible they are associated with an increased risk of both acute and chronic cardiovascular pathology. The most serious irreversible anabolic steroid side effects are associated with carcinomas-mainly of the liver, prostate and kidney. Hepatic carcinomas are strongly associated with abuse of the orally active 17alpha methyl substituted steroids, which also produce a reversible jaundice.
In males, anabolic steroid abuse causes suppression of LH and FSH release leading to inhibition of testosterone production often accompanied by testicular atrophy, and azoospermia. High, chronic doses of the drugs may also cause moderate to severe feminising effects in the form of gynaecomastia. Male secondary sexual characteristics are a side effect of AS abuse in women. Increased insulin resistance and elevated fasting blood glucose levels are the commonest non-gonadal endocrine side effects of AS.
AS abuse leads to contradictory, complex, behavioural, and psychiatric changes. Increased frequency of mental illness, in anabolic steroid abusers including paranoid schizophrenia, mania and depression has been reported. Physical and psychological dependency occur amongst some anabolic steroid abusers and severe psychiatric disorders can appear upon withdrawal, leading in a few cases to criminality and even suicide. We need more studies on the long-term effects of AS.
