Aerobic workout is an exercise that needs the heart to pump oxygenated blood to ensure that oxygen is delivered into the muscles working during the exercise. The workout invigorates the heart and breathing rates to get more oxygen into the body and sustain it through the workout session. The ability of an individual to take in oxygen and distribute it to working tissues, as well as the capability of working body tissues to use oxygen, is measured by oxygen uptake. Oxygen absorption increases for the first few minutes of low-intensity workout with a continuous power output before a stable condition is achieved.
There are several steps in the oxygen pathway from the atmosphere to the mitochondria, each of which may be a possible cause for the increase and decrease of oxygen that gets to the body tissues during an aerobic exercise. Some factors that could be influencing the oxygen increase and decrease could be, the diffusion capacity of the pulmonary system, the blood’s oxygen carrying capacity, and the characteristics of the skeletal muscle (James et al. 323). The pulmonary system is made up of the nose, trachea, larynx, bronchi and lungs. The lungs of an average person exercising at sea level do an excellent job of saturating the blood in their arteries with oxygen. The pulmonary system may influence the increase and decrease of oxygen delivered to tissues under certain circumstances such as aerobic workouts.
Activities like using steroids interfere with the blood’s oxygen carrying capacity by changing the blood hemoglobin content as steroids increase the amount of oxygen in the blood. During exercise, the lungs help to provide the body with energy by bringing oxygen into the body and expelling carbon dioxide which is a by-product when the body generates energy. The heart pumps the oxygen to the muscles during the aerobic workout, the body uses the oxygen taken in and produces more carbon dioxide as one exercises.
