Exercise is a very important activity in an individual’s life. Exercise helps individuals physically and mentally. Regular constant exercise allows an individual to increase their life span, it helps prevent them against heart disease, diabetes, high blood pressure, high blood cholesterol, and fewer chances of getting a stroke (Why Is Physical Activity Important, n.d.).
〖VO〗_2 maximum is the measure of the maximum volume of oxygen an individual can use and it stands for volume of oxygen. 〖VO〗_2 maximum is measured in millilitres per a kilogram of body weight per minute (ml/kg/min). As an individual increases their effort in an exercise, the amount of oxygen they consume increases (Running for Fitness, n.d.).
Before an individual reaches their 〖VO〗_2 max their body is undergoing aerobic respiration. Aerobic respiration occurs when the body produces enough energy to supply their cells. Since the body is able to supply all the oxygen to the muscles, the cells are able to produce ATP efficiently. Therefore, the individual will most likely be in their aerobic threshold that allows them to continue the activity for a longer period of time (The Science Behind Aerobic Fitness, n.d.).
Oxygen is needed to produce energy, the harder an individual exercises, the more oxygen they use to produce sufficient energy. If the individuals exercise exceeds the 〖VO〗_2 max then the anaerobic energy system is used to supply additional energy needed. Anaerobic metabolism is when the muscles uses…
