What is Blood Doping?

• An athlete removes and stores their own blood, then injects it back in themselves later.

• An athlete removes their blood, then forgets to inject back into themselves later

How do doctors use the age of red blood cells to decide whether or not someone was blood doping?

• His increased cellular respiration and improved performance.

• If doctors see that there are a lot of old red blood cells in the blood sample this can be evidence that the athlete was blood doping.

• The age of red blood cells

How can high-altitude training help athletes get more oxygen to their cells?

• Doctors use blood for evidence

• A change in diet could also help an athlete perform better.

• When athletes train at high altitudes with less oxygen, their body makes more red blood cells in order to get the most oxygen possible.

Blood Doping increases the number of Red Blood Cells in the body?

• True

• False

In parts of the cell called the mitochondria glucose and oxygen combine to make carbon dioxide and water, releasing energy. This is called cellular respiration

• True

• False
