How does hemoglobin change after exercise?

Answer 1

Because your body is working "overtime" because you are exercising, your muscles and all your body organs are needing more energy and oxygen, this is because your body is working more than usual. Your body needs to do many things such as sweat, which helps you cool down, and to get energy to all of your cells in your body to help you carry on exercising, if your body didn't do this, then you wouldn't be able to carry on exercising. The blood supply then has to increase because it has to go to the parts in your body which you are exercising the most eg. If you are taking a run, the blood supply will increase because your legs will need more energy, therefore there will be more blood circulating your legs than normal because you are overworking them? Does this make sense?

Answer 2

It may increae in diseases such as polycythemia vera and chronic obstructive lung disease.it may also increase in chronic smokers and individuals who engage in regular vigorous exercise or live at high altitudes.

Answer 3

During exercise, the blood flow to the active muscles increases to allow for more oxygen and nutrients to be available to those muscleswhich are using oxygen and available glycogen stores. This increase in blood flow also allows for more waste products to be carried away from those muscles being worked. Now that blood had to come from somewhere..... usually it comes from a person's core / trunk area. We all know that we do not have enough blood to go everywhere all of the time, our nervous systems are automatically taking care of this for us, but the processes of vasoconstriction (the reduction of blood flow to an area... in this case the core) and vasodilation (the increase in the diameter of blood vessels to allow more blood to flow to an area... in this case the muscles. Hope this helps!

Answer 4

While exercising, your muscles need more oxygen in order to create more energy through cellular respiration. In order to supply more oxygen, the heart beats faster so blood moves faster throughout the body.
Because the muscles need more blood i them Because your muscles require more oxygen which is delivered to them through the blood stream, which is pumped to them by the heart, so the heart beats to kep up with the demand.

Answer 5

There is a very simple explanation as to why blood flow increases when exercising. When you are exercising your heart rate is rising causing blood flow to increase.

Answer 6

As a carrier of oxygen, hemoglobin, attached to erythrocytes travelling through the body is increased in quantity to compensate for the muscles' need for more oxygen during physical exertion.

Answer 7

After maximal exercise, there is hemoconcentration with concomitant decrease of plasma volume hence hemoglobin changes
