Oxygen debt is the deficit of oxygen resuting from intense exercise. During exercise, the body cannot generate enough ATP (energy) to meet the needs of the muscle. This produces lactic acid, which causes muscles to fatigue. Oxygen is required to metabolize the lactic acid and replenish energy stores. How do we do this? We breath, rapidly to bring in large amounts of oxygen. Think of this concept as a checkbook with money being oxygen and writing checks as exercise. If you write checks, but run out of money, your account will go into debt. How do you get out of debt? You get more money.
cellular respiration
Decreased ATP does occur within a muscle cell during oxygen debt. It's accompanied by a decrease in oxygen levels and an increase in carbon dioxide as well as lactic acid.
If the demand for oxygen is not met for a long period of time, the cells within the muscle tissue will die.
Myoglobin
Coronary arteries carry oxygen-rich blood to the tissues of the heart muscle. The oxygen diffuses within myocardial capillaries.
TRIGNOID
Many of the changes in metabolism during exercise have effects throughout the body. In muscle, there is a increase in blood flow caused by both local factors as well increases in circulating adrenaline. These same hormones also increase the release of glucose into the blood by increasing the break down of glycogen stores. Glucose enters the muscle by because the concentration of glucose outside of the muscle cells is much greater than within (where glucose is being metabolized to make ATP). Oxygen is increased by increases in the rate of respiration and taking deeper breaths. Nonetheless strenuous exercise in muscle results in an energy and oxygen deficit that will lead to the exhaustion of the supply of ATP needed for continued muscle activity.
Into The Muscle; Within The Muscle
The benefits of using moist towels during massage are due to the changes that heat causes within the skin and muscles. The person receiving the massage is able to relax, muscle spasms are decreased, heat tends to decrease muscle pain and joint stiffness. It may also increase metabolism. A towel if used to drape a client, it is sometimes used by state law for legal massage therapy. It is also used to protect the privacy of the client.
Inferoapical ischemia is lack of blood flow below the apex.
Muscle type is polygenic and is probably influenced early on during the gastrulation phase. Since there is substantial variation within families all the alleles are not on the same chromosome.
