Exercise Physiology Essay

Effects of Running on the Respiratory System During running, there is an increase in the respiratory rate which is the rate at which one breathes. This is due to the increased metabolism in the muscles brought about by running. Thereby increasing the amount of oxygen that is needed and the amount of carbon dioxide given off. This increases the demand put on the respiratory system which then compensates by breathing faster. At rest, the respiratory rate is at 12 to 20 breaths per min but can increase

systems to supply oxygen during sustained physical activity (Lee, 2010). Maximal oxygen consumption, VO_2max, is one of the most shared ways to measure a subject’s CRF, because it is the measurement of oxygen the subject consumes while doing vigorous exercise. VO_2max is expressed in milliliters of Oxygen, per kilogram of body weight, per minute (ml/kg/min). Setty stated that, VO_2max “is the gold-standard method of cardio-pulmonary and muscle cell fitness” (Setty, 2013). CRF can be an affordable and

Interpretation: When a muscle exercises, it constantly contracts and relaxes, using energy in the form of ATP to do so. When intensive exercise is conducted (e.g. performing exercise at peak performance), there may be an insufficient amount of oxygen present in the muscles, resulting in the cells performing anaerobic respiration to produce energy. Anaerobic respiration produces much less energy than anaerobic respiration, though does so without the presence of oxygen. Performing anaerobic respiration

As previously stated, modifications need to be made to each individual program. For example, a sprinter will need to participate in more leg and core strengthening exercises in comparison to a boxer who aims to gain muscle and nimbleness. Looking at those two specific examples, there is a connection between strength and coordination. There is not a sport that does not require some form of coordination whether it is hand-eye

The purpose of this study is to show how exercise allows higher heart rates and more oxygen intake. To accomplish this, two people were chosen to run up and down stairs, and take each other’s resting heart rate after the exercise. They ran up and down the stairs for 1 minute. This was repeated two additional times to have more data to compare. As a result, running up and down stairs did actually increase their heart rates. This means that more oxygen was received because the heart had to work harder

during the exercise phase of the procedure. This increase is demonstrated by a general positive slope for the three lines during the exercise phase. The data for the carbon dioxide clearance and oxygen consumption also provided strong evidence in favor of the hypothesis. Figure 2 has a positive slope for all subjects throughout the exercise phase. Figure 3, however, has an initial positive slope for all subjects near the beginning of the exercise, but later levels off midway through the exercise. A potential

At The Finish -Jim has stopped rowing and his muscles are now at rest. Why are his heart and breathing rates still so high? Now, answer in terms of ATP production by way of aerobic respiration vs. lactic acid fermentation. (3 points) ~He was rowing intensively during the race, so he used up all his glucose and oxygen in his cells for provide the energy for his body. He is now using anaerobic fermentation at the finish line to complete the race. Once he stopped the race, the CO2 that was accumulated

Oxygen consumption (VO2) is the measure and the amount of oxygen being taken in and consumed by the body during exercise. Oxygen is used by its target tissues to produce energy (ATP), mostly through aerobic respiration, and allows us to calculate and determine the amount of energy being expended during exercise. Theoretically oxygen consumption would decrease as energy demand, aerobic metabolic rate, and power output increases; but for our lab the results seem to indicated that oxygen consumption

occurs when the body and the organs can no longer sustain itself. Specifically ultra-marathon running especially in the heat. Exercise in the heat is a physiologically challenging for the function of the cardiovascular (González-Alonso & Calbet 2003), thermoregulatory system (Johnson 2010; González-Alonso et al. 2008; González-Alonso 2012). Thus exposure to prolonged exercise in the heat that increases the body temperature increases the risk of heat illnesses (Armstrong et al. 2007) such as acute heat

other key factors benefitting into their growth stimulation such as supplements and nutrition. According to Berning it is not recommended for endurance athletes to intake protein as it drops their nitrogen balance, but it is recommended for those who exercise as it is adequate for muscle growth and recovery
