The practice of altitude training and synthetic EPO doping is usually done by endurance athletes.
Altitude training has been shown to improve aerobic capacity and enhance recovery. This would be extremely important to an athlete competing in a multi-stage event like the Tour de France.
Hemoglobin carries O2 is usually done by endurance athletes.
in the blood to working
Athletes that live high and compete low (at sea level where there is normal O2 in the air) have increased carrying capacity of O2 and consequently greater O2 delivery to tissues. This increases aerobic performance and speeds up the recovery process.
Synthetic EPO is available as a therapeutic agent produced by recombinant DNA technologyin mammalian cell culture
- used traditionally to treat anemia (decrease in the number of healthy RBC) as a result of cancer or chronic renal failure
- also used as a common blood doping agent in endurance sports

The illegal “blood doping” era is likely over but legal ways to increase whole body hemoglobin levels to the ceiling of 49.9% as permitted will continue in the future.
