Performance enhancing drug (PED)
used to gain adv e.g. run faster (doping)
Doping
use of banned PEDs by athletic competitors

Anabolic steroids
mimic effect of male hormone testosterone
promote muscle growth e.g THG
increase strength, power, aggression
less fat/lean body weight = decrease recovery time
e.g. strength/power athletes sprinters Dwaine Chambers
Erythropoietin (EPO)
artificially - natural hormone produced by kidneys
increase no of RBCs (increase aerobic & O2 carrying capacity) = endurance, delays fatigue
e.g. endurance performers, cyclist/runners
e.g. Lance Armstrong
Side effects of anabolic steroids
liver/kidney damage, heart and immune system issues
excessive aggression
masculinisation of women and acne
Side effects of EPO
blood clotting and thickening
strokes and heart attacks
Side effects of Beta Blockers
nausea/tiredness from low BP and HR
decreased aerobic capacity = heart failure

psychological reasons for taking PEDs
- beta blockers = steady nerves
- anabolic = aggression/arousal (weightlifting)
