Vo2 Max Research Papers

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.

The definition of VO2 is the maximum rate of oxygen consumption measured during incremental exercise. The definition of METs is the ratio of metabolic rate during a specific physical activity. The relationship between METs and activity are, the higher the MET level the more calories that are burnt and the higher METs the more intense the activity. The more Oxygen consumed during a VO2 maximal test, the more carbon dioxide is being produced, this raises the RER, RR, HR etc. A warm up before VO2 testing and a higher MET activity are important. A warm up will prime the body to make sure you are ready for the activity. Then , when you perform you must have a cool down to help lower your heart rate and replenish oxygen from the strenuous activity. Comparing my VO2 (48.8) in a national standards chart, I am in the 75th percentile. Using METs and Max VO2 is very helpful in making a program. You know what level of MET activity the client can withstand and you can control the intensity. Also, having HR zones, points where lactic acid build up starts and a plethora of data at your fingertips to manipulate in order to better train a client.

Both subjects recorded values for VE and FEO2% which allowed the absolute Vo2 (L/min) to be calculated. This was done by multiplying the VE by the difference between FIO2 and FEO2., where the FIO2 is always 20.93%. For the male participant during warm up, the calculation was .16VE x (.2093-.15) = 0.9488 (L/min) as his absolute VO2. This value was multiplied by 1000 to convert to ml and then divided by his body weight, 94.5kg, to find the relative VO2 of 10.04 (ml/kg/min).

The PFT tests were conducted pre-run, post-run, and at 5, 10, 18, and 30 minutes post-run. Then, on two separate days, the participants were randomly given their task of either running outside or inside. The outdoor runners were allowed a 1-lap warm-up leading to an 8-minute run that also targeted the runners’ 85-95% MHR. The indoor runners were given a 5-minute warm-up (3.5 mph) at a 6% grade and was followed by an 8-minute run that allowed for an 85-95% MHR.

The results of the study showed that the VO2 max test on the treadmill was greater than the VO2 max test on the cycle. This could be because subjects are more comfortable on a treadmill compared to a bike. Subjects had more to say about his or her soreness on the bike, making the subject feel fatigue faster during the test. Three subjects completed the VO2 max tests back-to-back days, leaving the subjects feeling sore from the first VO2 max.

Vans Maxed is the latest product that is directed to athletics and improving optimal performance. Figure 1 is a mockup of what Vans Maxed is expected to look like, still keeping the iconic Vans line on the shoes. In this research paper, we will look closely as to how Nike has built and extended their brand, as they are a major competitor and have excelled in marketing their brand.

Our subject, Laura, started off the Wingate test with a high RPM and a high power output. Laura’s watts began to decline rapidly around 12 seconds into the test due to her ATP and CP systems becoming depleted with energy. Since she is completing anaerobic exercise, her body needed to produce ATP energy another way which is the process of glycolysis. This process takes much longer, but is able to provide the muscles with the ATP needed, followed by CP and phosphogen. Laura’s normal exercising habits consists of working out approximately 1 hour a day, four times a week with an intensity level of 12 on the BORG6 scale. Her results showed that as an athlete, her endurance is better or more efficient than speed compared to other subjects in this class. Also compared to the class, her absolute peak power was the highest of all of the other subjects, but her relative peak power was one of the lowest. Laura also had one of the highest vertical jump scores with 29.1 cm. Since she's a runner, her lower body anaerobic capacity is pretty high which would benefit her being able to jump higher than

All participants completed an incremental maximal protocol to exhaustion on H/p Cosmos treadmill. The protocol was initiated at 8.5 km.h−1 with increments of 0.5 km.h−1 every minute at a 1% inclination. The oxygen uptake (V˙O2) and carbon dioxide (V˙CO2) production were monitored breath-by-breath using a metabolic cart (Oxycon pro analyzer with Jaeger software).Heart Rate and Rate of Perceived Exertion were monitored throughout the test until

Vimax pills are rated 1 penis enlargement drugs in the marketplace. This revision of the truth Vimax drugs could make you remember whether you sincerely see a change within the dimensions of your penis after utilizing the Vimax capsule. It is going to evaluation the communicate of taking Vimax capsules. Keep on studying to find out how it's viable for you to get what you want when you buy the Vimax tablet.

The more oxygen consumed, the more carbon dioxide is produced and exhaled into the Douglas bag for collection. Several studies have confirmed that VO2 levels increases during moderate intensity exercise (James and Doust, 1999). For example, one study examined individuals after a running exercise and found an increase in VO2 levels (James and Doust, 1999). Some studies also confirmed that an increase in VO2 levels can also be seen in high intensity activities as well (James and Doust, 1999). Studies in the past did not necessarily follow the exact procedure as this lab or made use of the same gadgets, for there are different kinds of computerized systems designed for the same purpose of measuring gas exchange during exercise. However, one study compared VO2 results using 2 methods; a more modernized gas exchange system and the Douglas Bag Method, results for the measurements of oxygen consumption and carbon dioxide production were quite close (Bassett et al, 2001). Though the Douglas Bag Method can be somewhat inaccurate for the reason that not all expired air is later evacuated from the bag, there will always be some air containing O2 and CO2 left in the bag which might have an effect on the VO2 results of the next trial. (Hopker et al, 2012). The objective of this lab is to determine the values involved in the gas exchange during exercise using a computerized system similar to that

The protocol is easy to conduct because all the individual needs to do is press start on the treadmill and then the session can start; it is also easy to set up because you only need a treadmill in your chosen sport. This test is also good because it can be used to measure the maximal hear rate of an individual during a workout, this is done by having a gas analyser, breathe through it, using the amount of carbon dioxide breathed out it can work out what the maximal heart rate is. This can then be used to work out the workload intensity that the performer is required to work at. Though it is a good laboratory test, it can’t used in all environments because of the equipments needed to conduct the test for example you need a suitable environment such as a gym or sports hall where you can place the treadmill, you can’t have it on a field, it also would take time to set up compared to other fitness tests if the required equipment wasn’t available along with a lot of money just to get the equipment for the

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

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.

My first physiological goal for a BMX racer is to increase VO2max. VO2max is the max amount of oxygen a person can consume. Typically, VO2max is thought to only be an important deciding factor during long endurance bases events where the primary source of ATP is from oxidative system, which is the only metabolic system dependent on oxygen.
