PEDs In Sport
Performance Enhancing Drugs
| Drug | Effect on Performance | Health Risks | Which Sports |
|---|---|---|---|
| Anabolic Agents | Allows performers to train longer and harder It increases protein synthesis helping develop lean muscle mass and speeds up recovery time | • Liver damage/CHD • Testicular atrophy • Infertility • Skin problems • Mood swings • Aggression • Baldness | Activities that require power: • Sprinters • Rugby players • Weightlifting • Boxers • Baseball |
| Beta Blockers | Beta blockers improve fine motor control by slowing heart rate and reducing anxiety which allow the performer to remain calm and controlled | • Nausea • Sleep disturbance • Tiredness/weakness • Lower blood pressure • Slow heart rate | Activities that require precision: • Archery/shooting • Snooker • Gymnastics |
| Diuretics | Diuretics achieve quick weight loss (fluids). They also mask other drugs making them harder to detect | • Dehydration • Nausea • headaches • Heart/kidney failure | Drug cheats and sports with weight categories: • Boxing • Jockey |
| Narcotic Analgesics | Narcotic analgesics increases the performers pain threshold so can mask injuries, also give a feeling of invincibility | • Nausea/vomiting • Anxiety/depression • Kidney/liver damage • Addiction • Risk further injury | Any sport that a performer is injured: • Boxers • Sprinters • Football |
| Peptide Hormones | EPO Erythropoietin (EPO) Can increase red blood cell production increasing O₂ delivery HGH Human Growth Hormone Helps muscle mass and burns fat | • Thickening of blood • Blood clots • Strokes • Heart attack • Arthritis • Heart failure • Abnormal feet/hands | Aerobic events e.g. long distance: • Running • Cycling Strength events: • Weightlifting • Sprinting • Rugby |
| Stimulants | Stimulants increase alertness, reduce tiredness and increase heart rate (therefore oxygen delivery) | • Insomnia • Anxiety • Aggression • Irregular heart rate | Alert/aggressive sports: • Rugby • Boxing • Ice hockey |
| Blood Doping | Blood doping involves the removal of blood a few weeks prior to competition. The blood is frozen and re-injected just before competition (increase red blood cells) | • Infection • Thickening of blood (viscosity) • Heart attack • Embolism (blockage of vessel) | Aerobic events e.g. long distance: • Running/cycling • Cycling • Swimming • Games players |
