This is partially true. Your energy level has to due with a combination of variables, blood flow (oxygenation of muscles), blood chemistry, physical condition, and many others.
more oxygen is taken up by the muscles/lungs; oxygen is used/needed for energy/ATP production/respiration
The faster your blood circulates, the faster blood can get to your muscles, giving you more energy in your muscles to use those muscles. Muscle cells need oxygen to work just like any other cell.
Anaerobic respiration is repairing without oxygen, so in a sprint for example, the muscles are working so hard that even with oxygen being breathed in, it is not enough to supply the energy, so anaerobic resooration takes place to release enough energy. With long distance events, the muscles aren't working as fast or hard, s there is enough oxygen, and no oxygen debt.
muscles. The cells need to produce more energy
Protien is made in your muscles on the fibers your eat and energy is made in your red blood cells. The more nuriousment the food the more the energy
That is correct.
False, while you need oxygen to release the energy in muscles (to move), once there is enough oxygen, adding more does not create more energy. The energy comes form the food you eat, not the oxygen used to burn it.
They can get some energy out of glycolysis, or the splitting of glucose into pyruvate, and the pyruvate can be fermented into lactic acid, producing more energy. This lactic acid is why your muscles get sore after oxygen deprivation.
When you are exercising, oxygen is released from your body more rapidly. Due to this, your heart rate increases to carry oxygenated blood to your muscles and organs so that they stay in working order.
more oxygen is taken up by the muscles/lungs; oxygen is used/needed for energy/ATP production/respiration
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.
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.
Lactic acid fermentation. This type of fermentation occurs when your muscles need more oxygen for energy, so fermentation gives your muscles a little extra energy.
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.
Your muscles require more energy when they are active during exercise. Muscles in your body metabolise glucose (sugar) in your bloodstream, breaking it down and taking it in to generate a high energy molecule known as ATP, which is essential for a cells functioning. Part of this process requires oxygen to fully break down the glucose-so when you need more energy metabolised, you'll need more oxygen too. If you don't get enough oxygen, your muscles will not be able to fully break down available glucose, they'll become fatigued and produce lactic acid instead- giving you a sore welling.
- Muscles require oxygen to function - When running, you are working muscles - Blood carries oxygen, the heart pumps blood When running, as the muscles require more oxygen to work harder, the heart must pump blood around your body quicker, delivering more oxygen to the muscles that require it. The way that the heart does this is to increase heart rate.
Proper breathing while exercising is very important. A person breathes deeper while exercising because their muscles need more oxygen, which means more blood cells need oxygen to carry to the persons muscles.
