Professional cycling has had much difficulty with cheating. Athletes and team doctors have discovered a variety of unnatural and illegal ways to improve sport performance. Cycling is highly aerobic which means oxygen is required to produce energy. If you have more red blood cells, you can carry more oxygen to working muscles. There are two methods of illegal blood doping to increase the number of red blood cells. 1. A few weeks before competition you would have some blood removed into a into a bag like when people give blood. You freeze the blood. Your body will pretty quickly replace the blood to normal levels. Before the race, you thaw and re infuse the blood. Now you (the athlete) have more than normal amounts of red blood cells. You can now carry more oxygen to yoru working muscles and have an unfair advantage. 2. You can also inject a hormone called erythropoetin (EPO) to stimulate the bone marrow to make more red blood cells. What two physiological systems are involved in method number 2. O endocrine muscle Onervous cardiovascular kinesthetic
