Muscles operating anaerobically are said to be in a state of?
Oxygen Debt
Do muscles enter into oxygen debt when they are functioning anaerobically?
i have no clue
How does oxygen debt affect performance?
it affect performance because lactic acid builds up in your muscles, which then causes shortness of breath and affects performance.
Why might a runner get cold after finishing a long distance race?
The runner's muscles needed a lot of energy to run during the race. To obtain this energy, his blood first supplies his muscles with oxygen from the lungs. The muscles, through a process called respiration, convert the oxygen and stored sugars into energy. During the race, his muscles used oxygen at a faster rate than his body could supply them with, creating an oxygen debt. To pay back an oxygen debt, a person must breathe at a fast rate. Therefore, the runner was out of breath after the race to pay back his oxygen debt.
What causes oxygen debt in muscles?
The concept of oxygen debt comes from the use of muscles during periods of extreme exercise. At this period, the muscles begin to burn more oxygen than the lungs and circulatory system are able to provide, so the runner or person exercising feels a burning sensation in the legs or arms and becomes short of breath (breathing more quickly to make up for the debt).
What happens when lactic acid builds up?
your muscles take over your neuromuscular body structure therefore causing an extremley irritating rash on your insilin sack. your bodys enzymes cannot function correctly and you turn into a motionless body but can only move abdominals and gluteus maximus muscles almost similar to a worm.
What do you do to replace the oxygen debt?
you repair the oxygen debt with exercise
Why do you get short of breath in a race?
You can move because your muscles respire, this involves using glucose and oxygen and turning it into water and energy. The more you move your muscles, the more oxygen you need. Oxygen has to go into the lungs then pass into the bloodstream to get to all your muscles. This process is limited so when you use your muscles a lot when running you begin to run out of oxygen. Your body compensates by performing more anaerobic respiration, which doesn't need oxygen. This produces lactic acid but allows you to keep running. The lack of oxygen is called oxygen debt, the faster and the more you run, the more oxygen debt builds up. When you stop running there is still all that lactic acid in your bloodstream and in your muscles. You need to keep breathing so your body can neutralise that acid otherwise your muscles would end up damaged.
Is it normal for your muscles to be smaller after your workout?
yes, the energy to move your muscles comes from aerobic respiration but if you cannot get enough oxygen to your muscles fast enough they will respire anaerobically, which means they will produce energy (in smaller quantities) and a by-product called lactic acid, this acid will break down the existing muscle until it is broken down itself by oxygen, which is why even after you've stopped excercising your heart and breathing rate remain increased, this is because youre body is working to repay whats called the oxygen debt.
What occurs if energy reserve in a muscle are depleted after heavy exercise?
an oxygen debt
How do you repay oxygen debt?
By breathing faster to take in more oxygen to get rid of the lactic acid that has built up from the oxygen debt.
After exercise why do pulse rates not immediately return to normal?
When you exercise (especially when you lift wieghts) you break down muscle. Your body needs to repair this muscle which is what makes you get bigger and stronger and in order to do that it needs to pump blood that contains nutrients to those muscles. You heart rate stays elevated for a while because your body is trying to "feed" all of the muscles that you used so it can reppair them.
