VO2 max

Introduction: 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…

Discussion VO2 max can be measured a variety of ways. There are many laboratory and/or field tests that could be completed by subjects to determine their VO2 max. According to McArdle (2015) “..usual activity modes include treadmill running or walking, bench stepping, and stationary cycling. In accord with exercise test and training specificity, other forms of testing employ free tethered, and flume swimming, swim-bench ergometry, in-line skating, roller skiing, simulated arm-leg climbing,…

attained their oxygen consumption (VO2) max. Each subject was able to pass 3 criteria to attain a VO2 max. To begin with subject 1 attained their VO2 max because the individual respiratory exchange ratio (RER) was greater than 1.15. As shown in table 1, the subject’s max RER is 1.2, which is greater than 1.15. Also, the rating of perceived exertion (RPE) was greater 17, as shown in table 1 the subject’s RPE is 20. Finally, the post VO2 max blood lactate level was 15.2, the requirement is 8.…

walking up and down stairs with ease or playing a game of tag with friends at the park, but at elite levels the higher the cardiorespiratory endurance of an athlete can make the difference between a good athlete and a professional athlete (Heyward and Gibson, 2014) Vo2 Max testing is a way in which to accurately record an athlete’s peak aerobic performance levels, the Vo2 Max test analyses the maximal capacity of aerobic work the body can output over a period of time. There are two types of Vo2…

It is important to monitor the environmental conditions before testing in the laboratory as Temperature, Humidity and Barometric Pressure can have significant effects on respiratory volumes and exercise performance. The Fick equation is used to demonstrate the rate at which oxygen (O2) is used during exercise. The Fick equation expresses the relationship of oxygen uptake (VO2) to cardiac output (Q) and arterial venous oxygen difference. The greater the VO2 max value, the more efficient the…

A measurement that measures the maximum volume that can be obtained by an individual is called VO2 max. VO2 physiology is two different categories 1) Utilization and 2) Delivery. Utilization is being able to extract and use oxygen. Delivery is about the transportation of oxygen cells either through the CVD or pulmonary system. VO2 is important for exercise and transporting oxygen to the muscles. VO2 max is important to health because it gives information on the function cardiac output of the…

effect, inexperienced participants, unregulated schedules, and unmonitored preparations which include proper diet and sleep, and sometimes illnesses of the participant. Notable key terms are oxygen deficit, VO2 max and…

Hypothesis: Even though the 1.5 mile run test will not produce the highest average VO2 max, the results of the 1.5 mile run test will produce the most accurate VO2 max results as the test puts the most physiological demand on the body compared to the Queens College/McArdle Step Test and the Rockport One Mile Walk Test. Discussion: The Queens College/McArdle Step Test, the Rockport One Mile Walk Test, and the 1.5 Mile Run Test are three different field tests that were performed in this lab that…

age decided to improve her lifestyle by being more active and eating healthy. After living a sedentary life she starts her training with a VO2 max at 38ml/kg/min, which is the rate of oxygen consumption that an person can utilize during intense exercise. After training for 6 months Mary Ann’s VO2 max increased to 52/ml/kg/min. I will be explaining how she was able to increase her oxygen consumption levels by increasing her cardiac output, and increasing her arterio-venous difference or in…

stage of the protocol and all equipment should be started simultaneously. All metabolic data are measured, displayed, and automatically recorded for the entire testing session. Using the Bruce protocol, the treadmill speed and grade should be increased appropriately every three minutes for the entirety of the test. The participant should be continuously monitored for any activity or behaviors that would signal the technician to terminate the test at a point before max effort. The participant and…
