Yes, cardiac muscles cells have a very high oxygen demand, since they are constantly in motion. This is why any shortage of oxygen causes angina, or if the oxygen deprivation is long enough, it causes death of the muscle cells - what is commonly called a heart attack.

∙ 14y agoYES! Oxygen is a necessary component for the muscles to create energy through cellular respiration. Without oxygen, your muscles would not have any energy.
Wiki User
∙ 13y agoYes they do. Muscles need constant supply of ATP, which requires oxygen to be produced in mass quantity.

Why do you breath very quickly after exercise?
Because when you work your muscles they need more oxygen, and to get more oxygen you need to breathe more often.
Why does the heart beat faster when exerciseing?
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.
What two things do muscles need?
nutrition and oxygen
What happens when muscles don't get oxygen?
whan your muscles dont get oxygen the dont work or they dont work properly.
Why do your pulse rate increase when you are running?
Your muscles need oxygen to work and oxygen is carried through the blood, propelled by the heart. When you run, you use muscles and your heart beats faster to increase the amount of oxygen reaching the muscles being used.
How does smoking effect your muscles?
it effects your muscles because if there is a shortage of oxygen in your body already, your muscles aren't getting the oxygen they need so they begin to become tired and cant work to the the best of their ability. for a sports performer this can be fatal because then they cant perform in their sport if their muscles can't. this is all because smoking has stopped them from getting the oxygen that they need.
Why does you heart sometimes need to work harder?
Your heart may need to work harder when your body requires more oxygen. For instance, if you are exercising, your heart rate increases to keep up with the muscles' oxygen requirements.
What is the relationship between your muscles andanaerobic respiration?
you use oxygen in your muscles to do work and anaerobic respiration uses oxygen.
Why do muscles use less oxygen during exercise?
They should use more oxygen your muscles burn either sugar or fat, it doesnt need oxygen to burn sugar, but the by product of burning sigar is lactic acid or pruvic acid, anyway it makes your muscles ache. if you are exercising and breathing hard, then you are burning sugars. to burn fat your muscles need oxygen. The harder you work the more ogygen is required.
Do muscles need oxygen to move?
Yes
Why does your pulse rate increase with exercise?
Becouse during the execise, the muscles need energy for doing their job. This energy is obtained by carbohydrate or fat burning, and for this reaction oxygen is needed. The more intensive the execise is, more quantity of oxygen it needs. For carrying more oxygen to the muscle, the heart needs to increase the number of beats per minit. This way more blood (carrying oxygen and carbohydrates) can be transported to the muscle.
Why does running make a person breathe faster?
Your body uses oxygen make energy, and muscles need energy to relax and contract, or flex. As you run, the demand for energy in your muscles increases, and so your lungs work harder to provide the oxygen your muscles are begging for. The result of higher demand for oxygen is faster deeper breaths.
