Exercise physiology – the difference between aerobic exercise and hypoxic exercise
Aerobic exercise is a more gentle exercise, such as walking, jogging, swimming, aerobic dance, tai chi, and riding a bicycle and so on. During these movements, because of the low intensity of exercise, the required energy requirements are also low, and do not need to be quickly provided in a short time, so that the body can easily inhale enough oxygen to supply the moving muscles.
Because the oxygen in the cells is sufficient, the cells not only produce more energy more efficiently, but also reduce the production of lactic acid, and the body muscles will not easily feel tired and sore. At the same time, the heart and lungs can better match the rhythm of aerobic exercise without feeling too much hypoxic stress, which is conducive to elderly and poor health.
In addition, aerobic exercise lasts longer, and when glucose is consumed as an energy source, the body begins to turn to alternative substances as an energy source. Next is a fatty substance being consumed, so that not only the formation of excess fat, but also can help clean up the blood free of fat , reduced fat accumulation in the vessel wall blocking blood vessels, reduce the risk of cardiovascular disease.
Another advantage of aerobic exercise is that it can expand the range of activities of various parts of the body through a soft rhythm, not just exercising a certain part of the muscle, so the development of the whole body is more balanced and healthier.
Normal muscle movement requires energy consumption. The greater the exercise intensity, the more energy is required. In the process of providing energy, the body consumes a certain amount of oxygen. . When the exercise intensity exceeds a certain limit, the body’s rate of oxygen intake may not be sufficient to match, resulting in a state of relative hypoxia, which is called hypoxia exercise.
During hypoxic exercise, muscle cells need to break down pre-stored glycogen to produce glucose-6-phosphate. Glucose 6-phosphate decomposes further under the anaerobic body, releasing energy in the form of ATP. The energy produced in this form is much lower than that produced under aerobic conditions, but can be used as a temporary emergency.
Common anoxic exercises include 100-meter sprints and weightlifting exercises. It stimulates the development of muscle cells and the cardiopulmonary system by creating an oxygen-deficient environment. The resulting lactic acid accumulated in the muscles causes muscle fatigue and soreness in the muscle. Moreover, the cardiopulmonary system of the body is relatively high, which is not suitable for the frail elderly.
