Any form of prolonged aerobic activity generally consumes a large volume of oxygen. Muscles, especially those in the larger muscle groups of the arms and legs, when put into motion during vigorous exercise over a period of time, use as much oxygen as the body can absorb. This can help develop the resistance power of a person who undergoes such activities. Some examples of these workouts include: cross-country skiing, cycling, jogging, rowing, swimming, and even long-distance walking.

The very limit as to the volume of that oxygen input is called aerobic capacity. In other words, this is the state where the body consumes the most oxygen during these long, vigorous exercise regimens. It is also known as aerobic power, aerobic power, cardiorespiratory fitness, cardiovascular fitness, functional capacity, maximal functional capacity, maximal oxygen uptake, or maximal oxygen uptake. There are several important factors that have an effect on it. Some of them include:

• Genetics. According to studies, there are some people who can be trained to improve their capacity through a gradually increasing exercise regimen. These people are called high responders. And then there are some people who are genetically born to have low responsive aerobic capacity. Low responders are genetically predisposed to have an aerobic capacity that plateaus at a certain level, and no amount of training can increase that. The best way to tell if a person is a high responder or a low responder is through a test called a VO2 max test, in which the person undergoes a pace of exercise, from walking to running at an increasing speed. on a treadmill. Breathing is monitored by a respirometer.
• Current state of health of a person. Another of the most important factors that affect it is the current state of health of the person. Incredibly, some apparently fit people forgo regular checkups thinking they don’t need them. Unfortunately, there may be some underlying medical conditions that have no symptoms… until now. People with lung or heart conditions or any ailment that affects the cardiovascular system are likely to have lower capacity. Age also dictates the current state of a person. People with advanced ages tend to have less capacity.
• Current state of daily physical activity of the person. This largely depends on the lifestyle of the person in question. Even seemingly active people who exercise regularly and watch their diets may have lower aerobic capacity than seemingly sedentary people who may not exercise regularly or subscribe to any diet plan, but are almost in a dynamic 16-20 mode. hours a day.
• Training is one of the most important factors affecting it. If a person undergoes regular training to increase it, there is a high probability that oxygen intake will be maximized as it should. The training, however, should be done gradually and under the supervision of a professional trainer. Safety is always a concern as the cardiovascular system, like all muscle groups in the body, needs time to build up.
