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.
What else can I help you with?
How does exercise change muscle strength?
It allows your muscles to work there for allowing more blood and oxygen to help them get less fatigued
Why does lung volume increase?
The lung volume that increases with exercise is vital capacity. When you exercise regularly, your body is more efficient at transporting and using oxygen, making vital capacity marginally bigger and exercise less difficult than someone who is out of shape.
What happens to the muscles when they are exercised?
The condition depend upon your regularity to do exercise They grow stronger and healthier if you do exercise daily but if you are irregular then whenever you do exercise lactic acid if produced in your muscles as the pryruvate change into lactic acid and a little energy due to less oxygen supply
Does the stomach gets more blood during exercise?
No, the stomach and intestines get LESS blood during exercise. The blood is needed in the muscles being used and is shunted there instead of digestive organs
What effects does exercise have on Arteriovenous oxygen difference?
Arteriovenous Oxygen difference measures the amount of oxygen extracted by the tissues from blood during one trip around systemic circulation. During exercise, cells consume more oxygen, therefore, more oxygen goes from the arteries to the cells and less oxygen circulates in the veins. This means that the Arteriovenous Oxygen difference increases with exercise.
Why does blood flow slowly in a kidney during a vigorous exercise?
Blood flow to the kidneys and abdomen decreases duringexercise because the muscles need more oxygen, and so, the blood vessels in them dilate. This causes more blood to go to the muscles, leaving less blood in the rest of the body.
What tissues have the greatest change in blood flow during exercise?
During exercise the trained body learns to redistribute blood from less active tissues like the digestive organs & kidneys to the heart & skeletal muscles.
Why is the blood flow to extremities reduced during exercise?
During exercise, blood flow to the extremities is reduced because the body prioritizes delivering oxygen-rich blood to the muscles that are actively working. The sympathetic nervous system is activated, causing vasoconstriction in the blood vessels of the extremities while promoting vasodilation in the muscles. This redistribution ensures that the essential muscles receive adequate blood supply to support increased metabolic demands during physical activity. As a result, extremities may receive less blood flow temporarily.
What products are formed during respiration in your muscles when there is less supply of oxygen?
Lactic Acid I know only one, there might be more.
Why is harder to run at high altitudes?
At high altitudes, the air pressure is lower which means there is less oxygen available for the body to use during exercise. This can lead to decreased aerobic capacity, making it harder to breathe and for muscles to perform optimally during running. Additionally, the body needs time to acclimatize to the lower oxygen levels at high altitudes.
What changes are noted in the heart sounds following the exercise period?
Heart sounds might sound less rhythmic following exercise. They will also be faster and louder since the heart is working harder.
Why does your breathing change after you exercise?
Your body needs oxygen to breathe, which it takes from the air around you, into your lungs, to your heart - where it is pumped to your muscles and organs. When the oxygen is used by your muscles, carbon dioxide is produced, which needs to be removed. So as the new oxygen goes into your muscles, the carbon dioxide from the last pump is taken out, where it is sent all the way back round to the heart, and then back to your lungs, and out of your mouth, back into the air.When you exercise, your muscles need more oxygen to cope with the increased levels of activity (the oxgen is used up quicker, by your working muscles, and so becomes carbon dioxide quicker) and so your breathing rate needs to increase. During exercise, your breathing will be increased more than normal.So when you stop exercising, your breathing rate slows back down, as your body is able to remove the carbon dioxide from your muscles more easily, and so less oxygen is needed to exchange for carbon dioxide.This explanation is a very simplified version - the acidity of carbon dioxide is also a factor as to why it is removed, etc.Hope that helps.KK
