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.

What effect does exercise have on breathing and heartbeats?
when exercise,your body lacks o2 and has to much c02 and needs too get rid of it. this increases your breathing and heartbeat.
Why does your breathing rate increase during a training session?
(as far as I know) The reason why the breathing rate increases is because, as you exercise, your muscles require more oxygenation, in order to fulfill this, you get more oxygen by breathing more, and your heartbeat increases to deliver the oxygen faster
What increases heart rate during exercise?
running
Can you use epinephrine for working out?
That would be a dangerous thing to do. Your heartbeat naturally increases as you exercise. Epinephrine is a potent drug and can be fatal if used improperly.
What molecule increases in the blood during exercise?
During exercise our blood circulation speed increases. It effect in amino acid and a molecule ATP which causes muscles to increase strength.
Why intravascular plasma increases during exercise?
bone stimulation
What substances increases in muscles during intense exercise?
lactate
What would happen to the blood pressure in the pulmonary artery if more blood is drived to the lungs during exercise?
The pressure in the pulmonary artery increases during exercise if the cardiac output increases.
How is the frequency of the heartbeat modified to meet the bodys need?
The frequency of the heartbeat is modified by the autonomic nervous system in response to the body's needs. For example, during exercise, the sympathetic nervous system increases heart rate to deliver more oxygen and nutrients to muscles. Conversely, during rest, the parasympathetic nervous system slows down the heart rate to conserve energy.
What is the apparent effect of exercise on the rate of the heartbeat?
Exercise typically increases the rate of the heartbeat, as the body requires more oxygen and nutrients to fuel the muscles. During physical activity, the heart pumps faster to deliver blood more efficiently. This elevated heart rate can enhance cardiovascular fitness over time, as the heart adapts to the increased demand. After exercise, the heart rate gradually returns to its resting state, reflecting the body's recovery process.
What does exercise do to the heartbeat?
the more you exercise, the faster your heart beat is. this type of exercise is called cardiovascular exercise. (cardio for short) this strengthens your heartbeat. exercise makes the heartbeat faster because for example: the faster you run, do you notice you panting? your body needs all the oxygen it can get when exercising.
What happens when the oxygen requirement increases during exercise?
aerobic respiration
