What are the Legal methods?
Aerobic training
Continuous training
Fartlek training
altitude training
Define Aerobic training
Aerobic training methods can include continuous, fartlek and long-interval training.
Each of these methods aims to improve the delivery of oxygen to working muscles as well as increase oxygen consumption (VO2 max) for energy production.
Continuous training
Continuous training involves continuous activity that lasts a minimum of twenty minutes at the required submaximal (70–85 per cent max HR) intensity.
Fartlek training
Fartlek training is a variation of continuous training that involves changes of intensity throughout the session.
Altitude training
Altitude training is a legal training method that involves training at levels greater than 1500 metres above sea level to induce physiological changes that enhance the oxygen-carrying capacity of the blood.
Potential Harms of Altitude training.
1) increases blood viscosity
2) weight loss occurs, the immune system can weaken
3) altitude sickness.
Erythropoietin (EPO)
Naturally occurring in the kidneys.
Stimulates production of RBC.
‘Synthetic’ versions exist.
Increases amount of hemoglobin in body.
Greater aerobic capacity.
Greater Vo2 Max.
Erythropoietin (EPO) potential harms.
Potential harms include:
Viscosity
Blood clots
Increased risk of heart attack and stroke
Dehydration
Blood Doping
Blood doping involves the process of infusing extra human blood into the body prior to performance. It can be an athlete’s own blood or that of someone else of same blood type . The blood is removed, then concentrated, frozen and stored.
Beta Blockers
Are medical drugs that block adrenaline hormones from binding to receptors on nerves, thus reducing the effect these hormones have on the heart and blood vessels.
