How many college students/professional athletes use steroids?
1/3
male and female % of high school students that use steroids
6% male, 2% female
Why do athletes use steroids
to build muscle mass or to speed recovery from training/injury
Muscle dysmorphia
“drive for muscularity”
What is the main building blocks of steroids
cholesterol
Natural steroids in females
Estrogen and progesterone
Steroid released by adrenal glands in response to stress?
cortisol
Types of steroids that are abused
anabolic-androgenic steroids
Why were anabolic-steroids developed
to treat hypogonadism - condition in which the testes do not produce sufficient testosterone for normal growth, development and sexual functioning in males.
Medical uses of anabolic-androgenic steroids are to treat
delayed puberty, impotence(lacking ability/power), wasting diseases in which body muscle is lost(HIV and AIDS)
Anabolic steriods
effective in building muscle mass, particularly in women(upper body)
What does androgenic mean
masculinizing effects
What happens when steroids are taken orally
substantial “first pass” metabolism - large portion will be destroyed in the liver. the drug may be inject to bypass the first metabolism.
Main reason anabolic-androgenic steroids are taken
to increase muscle mass and prevent muscle breakdown
typical medical dose of steroids(androgenic one)
100mg a week
Abusers often take how much a week of steroids?
1000mg a week
From the abusers perspective, the ideal steroid would have
strong anabolic effects, and weak androgenic effects.
build up muscle mass and promote recovery but not produce excessive masculinization
In men and women, use of steroids before growth is complete does what and why
stunted statue(never grow very tall) due to premature “closing over” of the ends of bones caused by the presence of huge amounts of testosterone.
What levels do anabolic steroids lower
lipid carrying proteins in blood
What levels do anabolic steroids increase
harmful cholesterol resulting in increased risk of heart disease
