There are two hormones that control the supply of sugar from the blood to the muscles. They are insulin and glucagon.
Because when your muscles are working they need more oxygen and nutrients, which they get from the blood. And for the blood to be able to carry more nutrients to the muscles the heart has to pump faster.
you're muscles need more oxygen which is carried in you're blood. this is why you breathe faster as well.
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
there are different techniques used to cheat via blood altering. one is a blood transfusion that some atheletes used to do basically to give them more blood hence more haemoglobin and a better ability to transport oxygen to the muscles = faster runner. EPO (erythropoietin) is a hormone that regulates red blood cell production and if atheletes take it they will have more red blood cells.
because you muscles need more blood so the heart pumps more blood
Insulin
The blood has to travel faster to deliver more oxygen to your muscles, as oxygen is the fuel used up by your muscles for movement. Since they're under more stress due to the exercise they use up oxygen at a faster rate.
heart pumps faster.
- Muscles require oxygen to function - When running, you are working muscles - Blood carries oxygen, the heart pumps blood When running, as the muscles require more oxygen to work harder, the heart must pump blood around your body quicker, delivering more oxygen to the muscles that require it. The way that the heart does this is to increase heart rate.
