Blood doping is a controversial topic in competitive sports and can involve injections of erythropoietin (EPO). Predict the effect on erythropoiesis and explain why an athlete might consider EPO injections to provide a competitive edge
What will be an ideal response?
Erythrocyte production, known as erythropoiesis, primarily involves a hormone known as erythropoietin (EPO). EPO injections can speed up the rate of erythropoiesis and reduces the amount of time needed for new erythrocytes to mature. More erythrocytes may be made as a result of EPO injections. Since erythrocytes transport oxygen, having extra erythrocytes means more oxygen can be transported to the athlete's muscles. More oxygen available for tissue can enhance performance.
