- reduced fat mass
- facilitate recovery after exhaustive exercise
- increased potassium and nitrogen
- leads to male expression (deep voice, bald,etc
- synthetic form of testosterone
- minimizes androgenic effects
steroid hormones
- directly affect nucleus
- lead to protein synthesis
- very potent
- small doses ineffective but large very effective
Dose relationship
- does threshold is higher than in clinical doses
- after threshold highly effective
AAS vs testosterone
-AAS easy to test
-testosterone more difficult b/c it is made by the body
4-1 ratio= positive test (deemed unnatural)
Aerobic athletes & AAS
- proven to increase red blood cell production and total blood volume
- increased O2 delivery to muscles
Concerns of AAS
- Moral and ethical concerns
- fair competition
- sexual risks (early growth stoppage, suppression of normal hormones (teste abnormalities) (excess of etrogen, boobs)
- women: disrupted mestruation or ovulation, male characteristics
