This is for the process known as "blood doping," which is almost always prohibited under athletic competition rules.
The athletes are trying to gain an advantage over other athletes by increasing the amount of oxygen their bodies can deliver to the muscles in a competition. The body ordinarily regulates the number of red blood cells that are maintained in the blood. But they can artificially increase this number before a competition (such as a race) by receiving a transfusion of their own red blood cells that were previously removed.
They have their blood drawn weeks before the race, and separate out the red blood cells (constituent known as PRBC for packed red blood cells). The day of the race, they get back a transfusion of these cells, and it takes a few days for the body to remove the excess cells. In the meantime, they can run farther or faster with this additional oxygen-carrying capability.
Along with drugs that stimulate red blood cell production, this process risks several metabolic conditions. High cell counts, known as polycythemia, can result in slower blood flow and excessive strain on the heart.

Are there more red blood cells or white blood cells in your bodies?
There are more red blood cells than white in healthy human blood.
What blood carries what to our bodies cells?
Red blood cells carry oxygen to our body's cells. This occurs with the help of hemoglobin.
How does our bodies filter dead blood cells?
lungs
Why do athletes have more red and white blood cells?
For endurance athletes especially because of the oxygen carrying potential of each red blood cell. The more red blood cells they have, the more oxygen being delivered to their cells during high intensity workouts. This is the whole basis of blood-doping; Athletes train in a high altititude where their body adapts to the low oxygen content in the air by producing more red blood cells. These red blood cells are then extracted and stored, and when needed are reinjected.
Can red blood cells utilize ketone bodies for energy?
Yes, red blood cells cannot utilize ketone bodies for energy because they lack the necessary enzymes to metabolize them.
How do red blood cells help athletes?
Red blood cells carry oxygen from the lungs to the muscles, which is essential for energy production during exercise. Athletes with higher red blood cell counts can deliver more oxygen to their muscles, improving endurance and performance. This can be especially important for endurance athletes like marathon runners or cyclists.

Which substance of blood helps in killing germs in the bodies?
Leucocytes or white blood cells(WBCs)
Does oxygen diffuse from large blood vessels into the bodies cells?
YES
Heinz bodies in red blood cells?
they are present in the asplenic syndrome
What do your bodies use to fight off diseases?
white blood cells
Why do athletes need a good supply of oxygen while carrying out training?
Athletes need a good supply of oxygen in their blood systems to perform at their highest potential. The more oxygen in the blood stream, the more oxygen is available to be transferred to each cells' mitochondria. The mitochondria produces the energy that a cell needs to perform at its best. So, the more oxygen there is in the blood, the better an athlete will perform. This is why athletes train at high altitudes without much oxygen - so their bodies produce more naturally. Then, when they compete at lower altitudes, their bodies have extra oxygen and thus, they are able to perform better.
