Exercise Oxygen Consumption ( Epoc )

Participant has completed an adult pre-exercise screening assessment, is currently fit and has no history of medical conditions in which to influence the results or compromise wellbeing.

In this report, I will be writing about the data that was collected from the beep test, which tests the aerobic endurance of the participants who are performing the test. With the results collected I will be discussing the different factors that may have impacted on the participant’s results. Robinson (2010) states that there are different systems in the body such as the skeletal, muscular, circulatory, and respiratory. Despite the fact all these systems are separate, they are all linked together to help the functioning of the body when at rest and during exercise. When the body begins to participate in exercise, during physical activity changes start to occur in the cardiovascular system starts so that it can adapt to the physical

In this assignment I will be introducing a formal report that is based on an investigation into how the body responds to exercise and which analyses the results from the investigation. The investigation involves myself and other pupils in my class. I will be doing the Harvard step test. the other pupils in my class will be monitoring my heart rate, breathing rate and temperature before and after the test.

After the exercise, we then took the measurements of our pulse, breathing rate and temperature too to see the change. Once we had completed this the first time, we then did it 2 other times, so in total 3 time so that the data was reliable and trustworthy. (Stretch, B., & Whitehouse, M. (2007).

In this lab, the focus was to study muscular fitness. In muscular fitness, there are two main components of measurements that are being taken, which are muscular strength and muscular endurance. Muscular strength is an individual’s ability to exert their maximum force. To test muscular strength, there are multiple tests such as 1 RM , Static Handgrip Strength, and Back Strength Dynamometer test. Muscular endurance is an individual’s ability to sustain prolonged muscular contractions. Tests that reveal results about an individual’s muscular endurance would be tests such as YMCA Submaximal Bench Press, Push-Up, and Plank test. It is important to remember that there is no single test for endurance and strength that will tell an

During exercise there is an increase in cardiac output, which corresponds to an increase in maximal oxygen consumption. With the increase in oxygen consumption, a greater increase in blood flow occurs. This means there is more oxygen circulating in the blood for the tissues to take up. Due to the increase in blood flow, vasoconstriction of arterioles occurs to maintain mean arterial pressure (Bassett & Edward, 1997). This limits oxygen consumption because some of the blood flow is directed to the brain and skin. It is further pointed out that the heart is another limiting factor because it determines how much blood and oxygen are supplied to the muscles especially when blood flow exceeds maximal cardiac output (Bassett & Edward,

Oxygen deficit occurs when the ATP production increases. It also occurs during the beginning of exercise. Anytime an individual changes the intensity of a workout, there will be an oxygen deficit. Oxygen deficit uses aerobic metabolism during an exercise bout.

If you do not know by now Exercise-associated hyponatremia is a fluid-electrolyte disorder caused by a decrease in sodium levels (hyponatremia) during or up to twenty-four hours after prolonged physical activity. Exercise-associated hyponatremia (EAH) first was described in Durban, South Africa, in 1981. If not taken care of immediately, EAH can led to tragic consequences. More than 500 marathons are held throughout the world each year, with the vast majority of competitors being recreational athletes as larger marathons can have tens of thousands of participants.

Throughout the course of this class, different aspects of physical activity have been explored through discussion boards, weekly physical activity participation, and a two week log of physical activity and recovery. After completing these activities, I have chosen three physical fitness goals; increasing cardiac health by improving my cardio endurance, increasing muscle tone by improving my muscle endurance, and losing weight by improving my nutrition and exercise. I chose to increase my cardio endurance in order to lower my risks for heart disease (Evans, n.d.). I chose this goal based on my two week log of my resting heart rate after a night of sleep. Although my resting heart rate according

The subjects were given a survey on their health as to avoid injured or asthmatic variables. Also they were all required to be in the healthy BMI range and the athletes were from one sport and the non-athletes had a strict definition of exercise as less than twice a week. However, a few errors could have slipped through. For example when recording the participants heart rate. The pulse was sometimes hard to locate requiring more time to look for it after their lap run and perhaps lose data in the process. Another possible error that could have occurred was taking the recovery times. The majority of the participant trials were done by one project partner making it difficult to monitor the thirty second intervals while measuring and recording the heart rates as well. In future studies these errors may be avoided by requiring all the researchers be present for the experiment in order to secure more definitive results. Another issue that occurred was the participants failing to show up, more so in the athlete group, which left a hole in hour experimental data because we were unable to reach the intended six athlete total due to this issue. Future researchers should attempt to have all the athlete and non-athlete participants together at one time for each day. This would avoid having to come back day by day and remember who did one day and who’s

In these experiments we talked about the Resting Metabolic Rate and Progressive Submaximal Exercise Testing to determine a subjects’ carbon dioxide production to oxygen consumption. This was done by having examples provided for us to calculate the RMR by using a formula, (X ml/kg/min x weight in kg) / 1000 mL= # L/min, to determine the number of calories burned at rest, as well having subjects perform the standardized treadmill test for 12-15 minutes for the Progressive Submaximal Exercise Testing.

Steps 1 to 6 were repeated for 1 minute for each trial to record down the initial resting heart rate for PASCO exercise. Result was recorded on results table for initial heart rate for PASCO type exercise.

Physical fitness has two main classifications-performance related and health related. People have different performance related requirements in accordance with their occupation but all people have the same health related requirements (The World). Then there are two types of exercise that helps tone a person’s body while increasing its endurance. These are aerobic and anaerobic. Aerobic exercise is exercise that uses the muscles and bones. Cardio activities are a good example of this, such as running or biking. This type of exercise increases the strength of a person’s heart and boosts their lung capacity. Anaerobic exercise is an intense but short amount of exercise (Payment). Since it is only for a brief amount of time, it does not require the amount of oxygen aerobic exercise does. Instead it uses glycogen which comes from the sugar in a person’s blood. An example of this exercise is weight lifting or sprinting. A person’s requires both anaerobic and aerobic exercise for good health. Simply doing a cardio work out is not healthy, and for a person to see real results there must be some activity like weight lifting (“Anaerobic”).

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
