Vo 2max Definition

This study examined the effects of jump rope training on maximal oxygen uptake (referred to as VO2Max). Previous studies show that “jumping rope can also be used to develop the coordination of neuromuscular skills, muscle strength, and cardiovascular endurance. It burns calories and builds strength in the upper and lower body” (Duzgun, 2010, pg. 184). The researcher hypothesized that these benefits of jump rope training would result in an increased VO2Max. Before testing, a single participant took a treadmill VO2Max pretest. The participant followed a jump rope training schedule for six weeks. After training, the participant took a posttest. The pretest and posttest showed a VO2Max increase of 1.1 ml/kg/min. These results indicate that jump

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.

The fourth, and most significant, response to training that a touch football player would experience is a change in their oxygen uptake. Maximal oxygen uptake, or max VO2, is considered by professionals to be the best guide for cardiorespiratory

Moreover, a recent study has found that there is an association between waist circumference and body mass index with cardiorespiratory fitness in healthy men and women.[4] In these models of age of 18 to 65 years old, hours of training per week, and weekly caloric expenditure in sport activity, significantly associated with VO2max. But however, this research is done with senior citizens of age with mean age of mean 50.1 ± 8.7 years old for males and 49.7 ± 8.9 years old for female, research on a younger generation has yet to be

The purpose of this lab was to understand how mammalian pulmonary and circulatory systems increase the delivery of oxygen to cells during exercise. The systems were examined by measuring pulse, vital capacity, ventilation rate, and the blood pressure at rest and immediately following short exercise. From these observations we measured the height, weight, body mass index (BMI) and smoking status in order to determine what may affect exercise (Barrilleaux, 2014).

VO2 max is the highest rate at which oxygen can be taken up and utilised by the body during exercise (Bassett and Howley, 2000). It is how CV fitness is measured. Studies show that for sedentary older adults undertaking aerobic training, VO2 has a net increase of 3.78+/-0.28 mL.kg-1.min-1. This is a long term effect, and the best results come after over 20 weeks of aerobic training. (Huang et al., 2004).

Through this lab we demonstrated how carbon dioxide production varies between athletes and nonathletes. Athletes are known to have more mitochondria, since they exercise more often (Murray, 2014). Which made us believe that they would be more efficient at carbon dioxide production compared to nonathletes. So we decided to test this theory through a variety of tests ranging from resting to exercising to indoor and outdoor along with heart rate, breathing rate and carbon dioxide production.

VO2max is the maximum rate of oxygen you can take in and use during exercise and is the typical parameter we look at when focusing on endurance exercise and aerobic respiration. Endurance exercise relies on the ability of the heart and lungs to work continuously for a relatively long period of time and VO2max, under aerobic respiration, (Cooper, D.M., Weiler-Ravell,

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

During this lab, various lung volumes and capacities for one subject were calculated for different conditions. These conditions included at rest and during 3 bouts of exercise varying in resistance on a cycle ergometer. Two subjects were supposed to participate in this specific lab, but there were technical difficulties with the computer set up, which only allowed for one individual to complete the entire procedure. The experiment began by having the subject sit down and breathe normally for 3 minutes into the transducer. Then, the participant performed 5 complete breathing cycles and at the end of the last cycle the individual was directed to inhale as deeply as possible followed by an exaggerated exhale. From there, the volumes were measured, including tidal volume (TV), inspiratory reserve volume (IRV), expiration reserve volume (ERV) and residual volume (RV). Next, the 3 exercise bouts at 60 repetitions per minute (RPM) occurred. The first exercise bout was at 0 kg followed by another at 2% and one at 5% the subject’s body weight, respectively. Similar to the resting condition, the different volumes were calculated for the 3 exercise bouts. After gathering all of the different values for the volumes, the capacities were calculated by using various equations.

Cardio respiratory fitness- Cardio respiratory fitness has to be near or at the level necessary for competition.

VO2max is the maximal amount of oxygen the body can uptake and use (Kenney, et al., 2012). VO2max is a very important factor when talking about the function of the oxidative energy system. Without the presence of oxygen the electron transport chain will be forced to stop. The electron transport chain turns NADH+H+ and FADH2 from the Krebs cycle into ATP if the supply of oxygen does not meat the demands of the electron transport chain it will stop. Once the electron transport chain stops the Krebs cycle will not be able to get rid of its NADH+H+ and FADH2, resulting with it stoping too. Another by product of the of the electron transport chain is the acidification of the blood. Acidic blood as a result of increased H+ ions inhibits a muscles

Participant were instructed to complete three-five minute bouts of exercise on the cycle ergometer (Monark Ergomedic 828 E) at a cadence of 60 rpm. The first stage was performed at a resistance of 1kp, the second at 2kp and the third at 3kp. At the three minutes and thirty seconds into each stage the subject was connect to the mouthpiece apparatus and removed at the end of each stage. During the final minute of each stage one respiratory cycle was recorded using LabChart as many times as possible to ensure a better data sample to choose from. The best respiratory cycle recording was labelled and used to obtain PEF and PIF. All pertinent data was then transferred into Microsoft Excel to enable data

The purpose of the maximal oxygen consumption test is to assess a participant’s aerobic power and fitness. Maximal oxygen is defined as the “single highest oxygen consumption elicited during graded exercise to exhaustion” (Adams, 2014). However, peak oxygen is measured “during a specific test, but it may not truly be the highest or maximal oxygen consumption possible” (Adams, 2014). To simplify, every test will show values for peak oxygen consumption; however every test does not always show a value for maximal oxygen consumption. This could happen if a participant is not able to fully reach the point of exhaustion due to physical pain symptoms or lack of motivation. Maximal oxygen consumption is important to understand aerobic fitness because it utilizes many systems in the body such as pulmonary, muscular, and cardiovascular. According to an article in the Journal of Human Kinetics, “maximal aerobic power is commonly accepted as the best measure of the cardiovascular systems’ functional limits (Rowell, 1974) and has been shown to predict mortality from all causes in healthy (Blair et al., 1989; 1996) and unhealthy individuals (Myers et al., 2002)” (Hamlin et al., 2012). For this lab, the maximal oxygen consumption test used was the Vo2 Max Bruce Protocol test and the equipment used was a Woodway treadmill.

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.
