Essay on Maximum Amount Of Oxygen Consumption
Maximal oxygen uptake, or VO2 max represents the maximum amount of oxygen consumption attainable during all out aerobic exercise, most commonly running on a treadmill. The point at which oxygen consumption plateaus is the individual’s maximal oxygen uptake. If the individual does not plateau, that point is referred to as VO2 peak. VO2 max is measured in milliliters per kilogram of body weight per minute, and there are two ways to measure it, either direct or indirect. The direct method requires the subject to exercise to the extremes of their capability, and indirect methods use sub maximal exercise. For this lab, we used the direct method. It can be tough though, because it requires the subject to exercise until exhaustion, requiring enough motivation.
Some main factors affecting VO2 max are age, gender, and altitude. VO2 max is typically highest by age 20, and gradually decreases as the individual ages. Males have a higher VO2 max due to their physiology, which is about 20% greater than females. In higher altitudes, less oxygen is available, thus lowering the VO2 max.
The goal of this laboratory was to measure a subject’s VO2 max using a metabolic cart and treadmill, and analyze the results recorded throughout the process. These recorded results include heart rate and rate of perceived exertion. VO2 max is a good measure of one’s endurance fitness but if used for athlete that trains or competes on different terrains, then it may not be as accurate. For…
