Vo2 Max Test Paper

During this laboratory three submaximal test were done. YMCA Submaximal Bike Test, Astrand Submaximal Bike Test, and The RockPort 1-Mile Walk Test. Each of these test required taking Blood Pressure,Heart Rate, and times, either at rest or while exercising. Everyone is a different when it comes to Blood Pressure and Heart Rate. They both depend on how conditioned the person is. The hypothesis is determining which test produced the highest Heart Rate and at what times. Since resistance makes a person work harder, we assume that test will be the YMCA Submaximal Bike Test.

VO2 max is the maximal volume of oxygen can be taken up and used by our body during exercise. Based on my understanding VO2 max can be determined through exercise intensity and duration. It is calculated by measuring the volume of oxygen consumed while running on a treadmill. With running there is an increase in oxygen requirement as speed increase and greater distance is covered. However after a certain point oxygen intake reaches its maximum point and it cannot go higher and VO2 plateau is obtained. The VO2 max paradigm by A.V. Hill states this could be due to the limitation in the cardiovascular and respiratory system (Bassett & Edward, 1997).

To test the capacity of a person’s lungs is to use the Functional Residual Capacity method, this measures the amount of air in the lungs after a normal breath. This will be taken before the aerobic exercise is taken place. To measure their lung capacity after the 5 minutes of exercise, their breathing is slightly more forceful and that must be taken into account therefore measuring the Expiratory Reserve Volume which is measuring an exhale that is slightly forceful after exercising. These measurement will be compared in a table along with other data containing height, athletes and non-athletes. One of the ways their capacity is being measured is by using a spirometer although it takes a forced breath to calculate its capacity. Another method

For this experiment, blood lactate was maintained with only a slight variation at the 75 minute time point, in which the value of blood lactate was 3.13 mmol/L. The other time points (from the 15 minute time point through the 90 minute time point) indicated a blood lactate value within the range of 1-2 mmol/L. The baseline value was slightly lower than 1 (0.953). During the TAT, the subject’s blood lactate rose to 7.82 mmol/L and continued to stay elevated 10 minutes post-exercise (7.64 mmol/L).

Steady state exercise is the activity that achieves a balance between the energy required by working muscles and the rate of oxygen and delivery for aerobic ATP production. This lab is conducted to determine the heart rate in beats per minute (BPM), blood pressure (systolic and diastolic), and rating of perceived exertion response at rest to moderate cardiovascular exercise at a steady state workload and RPM. I hypothesized that exercising on an exercise bike the subjects participating in this study would have a higher rate of fatigue without fluid replacement than with fluid replacement.

Subject will complete two main trial tests in a randomized cross-over design. In each trial, subject will cycle at 55% VO2max for 30 minutes. During exercise, the subject is required to drink one of the two different solutions: water and glucose solutions: water (W) and glucose solution (G). The solutions will be provided to the subject immediately pre-exercise, every 15minutes during exercise. The volume will be the same, 3ml/kg for participant. After exercise, subject will rest in the lab for another 30 minutes. The data will be collected at certain time during the lab practice, as

My client shows mixed testing for Vo2 max. He was in the 10th percentile for the one-mile walk test, 25th percentile for the submit treadmill test, and the 60th percentile for the Six-Minute Walk Test. All three tests, though there is a variance in the predicted Vo2 max, suggest my client could use some improvement in his Vo2 Max. Accouding to the ACSM assessment manual submaximal testing is less accurate in predicting cardiovascular endurance than Maximal Exercise testing (ACSM, 2010).

Subjects were not carefully monitored while performing the vital capacity test which can result in higher or lower readings. Multiple factors such as illness, asthma, and body composition were not addressed in this

The experiment consists of testing maximum VO2 uptake for the subjects to measure their caliber of training, whether the subjects had no training for a few years or those who have been participating in intense exercise. Also, each subject had a muscle sample of his or her gastrocnemius (lateral head) taken by a needle biopsy technique.

The main point of this report was to determine if pulmonary function was a limiting factor in regards to reaching V˙O2 peak [maximal aerobic capacity]. There were thirty-two Sunshine Coast University students that were tested over the two-week period of class. The first session was to figure out the students V˙O2 peak by participating in increasing high intensity exercise. Whereas, the second class was more to do with discovering pulmonary function and measuring forced vital capacity [FVC] and forced expired volume [FEV]. Overall, the results had proven that overall lung function was not a primary limiting factor- even though there was a positive correlation in determining V˙O2 max.

When working with clients in the future, we need to test how trained they are and ways to improve their economy to make exercise more beneficial. This will keep clients coming back because economy improves with practice. The model of performance shows that improved VO2max and improved economy leads to an improved Lactate Threshold and therefore an improved performance. An improved VO2max and an improved economy allow an individual to perform at a greater skill level and fatigue less quickly. Running barefoot can help elite runners as well as those just beginning to run. The goal is to improve performance and maximize the results and benefits of physical activity; and improving economy is one way that will maximize the results and

and aerobic endurance. It is measured in ‘milliliters of oxygen used in one minute per kilogram of body weight. Nevertheless, it is important to understand your individual VO2max as it is considered to be the best indicator of aerobic endurance and cardiovascular fitness. The actual measurement is done in ‘milliliters of oxygen used in one minute per kilogram of body weight. By knowing your VO2max, it enables an individual to set realistic goals and assess their improvement over time. Many people who exercise, or want to begin exercising do not understand what specific duration, intensity, or heart rate, would be the most beneficial in achieving the goals set. Thus, by having a clear understanding of VO2max an individual can clarify the specific target heart rates, fat

The results supported that the female swimmers had a higher lung performance than the female non-swimmers. The swimmers’ total average was 34.61 L/min higher. This could be explained by the fact that that the swimmer subjects had been swimming routinely and competitively for the past four years. This also leads to the question as to if their lung volume is also greater than non-swimmers. This could be studied by assessing the same subjects with a different pulmonary test such as the body plethysmography. Other tests could also be performed to more accurately assess the subjects’ lung function. Peak flow meters are typically used for asthma patients to measure the strength of their lungs. Tests such as the spirometry and the gas diffusion provide

VO2 max is the maximum oxygen intake during a high intensity exercise. The test is typically done on a treadmill, or cycle ergometer. The VO2 max test reflects the aerobic fitness of the test subject and the endurance the subject has during prolonged exercise. The subject who are fit usually have a greater VO2 max, and can exercise for longer periods of time than other who are not physically fit. Pro athletes usually have a higher VO2 max because they train hard in order to be physically fit.

I do not believe that the submaximal tests were accurate. When comparing the relative predicted VO2MAX values, the non- exercise test predicted 2.22 (L/min), the 1- mile walk/ run test predicted 2.62 (L/min), the step test predicted 2.04 (L/min), the YMCA cycle ergometer test predicted 1.83 (L/min), and the submax treadmill test predicted 2.22 (L/min). The most accurate of the submaximal tests was the submax treadmill test, as when compared to the 1-mile walk/run test, the predicted values were the same. For the most part, the submaximal testing predictions varied significantly when compared to each other, which is likely a result of testing discrepancies and error in measurements. To predict VO2MAX, all tests used an equation used for all populations, and is not specific to the client at all (Bennett et al., 2016). Additionally, it is likely that there were measurement errors taken during test such as being able to identify HR immediately after completion of the step test. The test, I believe, to be most accurate was the VO2MAX maximal graded exercise test. Although a true VO2MAX was not achieved, if the client could have lasted a few more seconds on the treadmill, it is likely that two
