Does exercise affect heart rate and how?
During exercise, the muscles of the body are at work and for the muscles to work energy is required. In order to provide energy to the exercising muscles the blood supply to the muscle increases so that the glucose-a monosaccharide sugar, C6 H12 O6, occurring widely in most plant and animal tissue; it is the principal circulating sugar in the blood and the major ener
At the same time, the oxygen requirement of the exercising muscle increases which causes the heart rate to increase in the respiratory system. So in order to provide energy to the muscle, glucose works as a fuel. These are the factors, which increase heart rate whenever there is a strain on any skeletal muscle. This results in increase of the heart rate. Nutrients and oxygen is supplied by the blood stream to the Myo Cardium, which helps in pumping the blood faster into the skeletal muscle. Now this results in an increase of blood flow from the coronary arteries to the heart muscle, which is also known as the Myo Cardium. If the blood is low in glucose, glycogen-a polysaccharide, (C6 H10 O5) n, that is the main form of carbohydrate storage in animals and occurs primarily in the liver and muscle tissue; is readily converted to glucose as needed by the body to satisfy its energy needs-is metabolized into glucose. gy source of the body-is mobilized to the muscle through the blood stream. By the virtue of increased coronary blood flow to the heart muscle or the Myo Cardium, heart rate increases.
