Introduction
In 1997, Sports Illustrated asked 198 aspiring US Olympians,
“Would you take a banned performance enhancing substance if you were guaranteed to win and not get caught?”
98% said “YES”
Then, when asked,
“Would you take the same undetectable substance if it would contribute to winning every competition for 5 years, then result in death?”
Over 50% still said
“YES!!!”
When your best just isn’t good enough…
DRUGS USED AS PERFORMANCE ENHANCERS
• Anabolic Agents• Peptide Hormones and Analogues• Creatine• Stimulants• Diuretics• Cannabinoids
ANABOLIC AGENTS AS PERFORMANCE
ENHANCERS
Anabolic Steroids TESTOSTERONE PRECURSORS
Enhance muscle mass gained from strength training
Speed recovery after exercise
NAMES OF SOME ANABOLIC AGENTS
• Androstendiol• Danazole• Nandrolone• Androstenedione• DHT• Clenbuterol
ADVERSE EFFECTS OF ANABOLIC STEROIDS
Gynaecomastia, Testicular atrophy, Increased libido Irregular menstruation, masculinization, acne Hepatic peliosis, Hepatoma, HCC Adverse lipid profile Premature epiphyseal closure Mood alterations
PEPTIDE HORMONES AND ANALOGUES
Human Growth Hormone
Insulin-like Growth factor
Erythropoietin Newly discovered
Protein anabolic action
Increases PCV
CREATINE
Regeneration of muscle ATP store
Cr + Ph = Cr-Ph; Cr-Ph + ADP + H+ = Cr + ATP
Adverse Effects:- (1) Muscle cramps
(2) Interstitial nephritis
STIMULANTS
Increased catecholamine Increased lipolysis
CNS stimulation Improved respiratory function
Increased alertness
Allays fatigue
DIURETICS
Any diuretic may be used
Mechanism of Action:- (1) Body weight reduction (2) Elimination of other doping agents through urine
Adverse Effects:- (1) Dehydration (2) Cardiac arrhythmias
CANNABINOIDS
Raise the pain threshold
Adverse Effects:- (1) Lowered psychomotor performance (2) Altered perception
METHODS OF DOPING
Blood Doping
Gene Doping
CARBOHYDRATE LOADING
CONCLUSION…
Before you attempt to beat the odds… be sure you could survive the odds beating you
THANK YOU!
