Well, to be specific, caffeine (like most psychoactive drugs) exerts its effect on us by altering the activity of some of our neurotransmitters. Neurotransmitters are the nervous system's way of conveying messages between neurons, and also to muscle tissue. Some neurotransmitters that caffeine is known to increase the activity of are norepinephrine, dopamine, and serotonin. The increase in norepinphrine is likely what causes the heart rate to increase, however each of these neurotransmitters has some stimulatory effects. Norepinephrine, however, is a powerfully stimulating neurotransmitter; it is associated with the 'fight or flight' response, which of course includes an increased heart rate. I believe it may effect epinephrine as well, which is similar to nor epinephrine except that it is also a hormone (and a neurotransmitter). This means it has both short and long lasting stimulatory action.
Caffeine is a stimulate, a drug, thus it is making your heart beat fast to pump more blood through your system. That's why Caffeine helps keep you awake also
This is because when you run your heart is pumping blood all the way through your body very fast.

I presume you mean, "Does caffeine speed up your heart rate?" Then... idk look it up
because (i think) you're using your muscles more, which makes them tired, so more blood needs to be flown to them. your heart pumps faster because it has to pump more, and you breath faster because the purpose of blood is to bring oxygen throughout your body. so the harder you work, the more tired you get, and that's why it happens... i think. this isn't a definite answer.

your heart beats several times a day it beats at least 10000 times a day but when we are doing fitness our heart beats faster which makes our heart have more beats there are about 10000000 beats when you go play a soccer game then after go for a run and after that go and do some wait training. this answer is completely correct.
The heart pumps, usually, at a steady rate between 60-80 beats per minute. The heart beats faster during exercise, fear or fright, and in illness. Ironically, regular exercise makes your resting heart rate become lower because the heart works more efficiently as a muscle. But having a fast heart rate, especially a persistently fast heart rate will not make you stronger; it actually makes your heart work HARDER.
<b> Caffeine actually does raise a persons blood pressure.
More blood is pumped around the body because the heart beats more. When the heart beats more the that makes the blood move around the body faster :)
