As muscles work harder and more energy is expended, oxygen demand rises. As a result, you breathe harder, increasing the rate and depth of respirations and, thus, take in more oxygen.
This type of exercise, during which the body's oxygen need exceeds the lungs' ability to replenish it is called anaerobic exercise -- literally, 'without air.' Exertion of longer duration, during which the body is able to sustain the energy output (and the lungs have the capacity to provide the necessary oxygen for a longer period of time) is known as aerobic exercise.
Oxygen is a necessary ingredient for burning.
yes!! exercise is very necessary it is important to exercise to keep fit and not pile on weight and if you don't your heart wont be as strong
shih tzu is a laid back breed they don't need much exercise, long walks are not necessary, they get tiered easily due to their flat faces they have a hard time getting oxygen.
Oxygen is necessary but water vapor is not.
you repair the oxygen debt with exercise
Exercise that usually requires a heavy use of oxygen
exercise
Aerobic exercise requires oxygen, anaerobic exercise does not. Aerobic exercises include walking, running, swimming, and jumping rope.
During exercise, your body uses energy. This process requires oxygen. So, if you exercise you pant, or breathe harder, in order for your body to draw in more oxygen.
anaerobic exercise is an exercise whereby an an individual is active in the absence of oxygen.
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.
