Detailed explanation-1: -A high red blood cell volume facilitates a high oxygen transport to the active skeletal muscles by facilitating a high cardiac output. Higher volume of red blood cells equals higher athletic performance. Consequently, improvement of hemoglobin mass has such a prominent role in the training of high-performance athletes.
Detailed explanation-2: -These younger red cells are characterized by improved oxygen release and deformability, both of which also improve tissue oxygen supply during exercise.
Detailed explanation-3: -Red blood cells are adapted for the transport of oxygen. They are small and flexible so they can fit through narrow vessels, have a bi-concave shape which maximises their surface area to absorb oxygen, have a thin membrane so gases easily diffuse through, and contain haemoglobin which binds to oxygen.
Detailed explanation-4: -What does it mean when your red blood cell count is high? If you have a high red blood cell count, then you have something called erythrocytosis. This makes your blood thicker than it should be, and it could increase your risk for blood clots.
