Vertical Jump Test Essay

Functional Aerobic Impairment (FAI) was the next value looked at. FAI assesses the difference between a people’s aerobic capacity based on age, gender, and usual activity level. It’s measured by a percentage and used to determine the level of aerobic impairment a test subject may have (Franklin, 1989). There are five different categories that the different percentages fall under: no significance, mild, moderate, marked, and extreme. Looking at the results above, all but one of the females had a negative percentage, while all of the males had positive percentages. The lower the FAI score or percentage the better, this means the test subject has a higher VO_2max than what was predicted, giving them a better health status. The negative values,

Unlike most studies and tests that measure and examine jumping ability and leg muscle power, the vertical jump test is extremely inexpensive to conduct. Although the vertical jump test is simple, easy, and quick to perform, there are numerous disadvantages to the test as well. In the vertical jump test, an individual is asked to attempt to touch the wall at the highest point of their jump. When the individual jumps, their technique and form play a large role in maximizing their jump height. The jump height can be affected by not only how much the individual bends their knees before they jump, but also by how effectively the individual uses their arms.

Choosing a vocation can be a daunting task. With the world ever-evolving, one may come across a new attractive career every year. In order to ensure optimal job satisfaction, it is vital to educate oneself about every alluring prospect prior to committing. Simple factors like the time commitment and salary can mean the difference between a content existence and a miserable one.

In order to enhance the ATP-PCrA system and increase peak power a form of high intensity interval training known as sprint interval training has been beveled and has shown results in sprint cyclist (Bayati, et al., 2011). This style of high intensity interval training has been shown to increase peak power. Another study by Laursen, et al. (2002) used highly trained cyclists and prescribed them a training plan incorporating repeated sprint interval training for 2 weeks. There was a mean increase in power of 4.3%.

I did 10 and ¾ laps which is 2150m, according to the table below my results are poor, this could be because I don’t train my cardiovascular system much so doesn’t improve at a good rate. If I was to work on improving my cardiovascular system more by going on runs then my heart can get stronger and my left ventricle could pump more blood than it does. It could also be that I didn’t know how to pace myself so I never really pushed myself properly. This test was difficult as it put a lot of pressure on my calf muscles. The respiratory system was heavily involved as having the right breathing

A sub-maximal steady state exercise requires carbohydrates and fats to be oxidised in order to create sufficient ATP for the body to function and complete muscle contractions. The main energy sources being used throughout the test were the aerobic glycolytic and the aerobic lipolysis systems. To determine which energy system was predominately being used we can use RER. If RER is a value of .7 the energy system being predominantly used is the aerobic lipolysis system, where as a value closer to 1 predominate system being used is the aerobic glycolytic system. This ration being used is calculated by the whole volume of CO2 expired and the volume of oxygen intake per minute (VCO2/VO2). (Bellar & Judge, 2012)

During the treadmill lactate threshold tests, there was an occasion of errors read on the Lactate Plus. This would lead to having to retesting, forcing the subject to pause for a longer period in between stages. The delay could change the reading of the blood lactate level. Subject three is considered a highly trained endurance athlete and required a different protocol for the

According to the bench step test and the cycle ergometer test, Carson has a VO2 max of 60.93. According to the percentile values of maximal aerobic power table, on page 171, Carson’s VO2 max is in the 95th percentile. Carson already has an excellent VO2 max which shows that he already does a lot of aerobic exercising. If he keeps working out, then he could possibly increase his VO2 max into the 99th percentile. In comparison, my VO2 max was 44.99. On the table, 44.99 falls between the fair and good division. I am in between the 55th and the 60th percentile. To improve my VO2 max, I could try cycling and jogging a lot more since I love being out in nature. In this lab, we performed submaximal test and one subject was in the 95th percentile while

This concept was called the crossover concept. This concept examined the effect that intensity had on the metabolism of the two macronutrients, at low to moderate intensity the body relies mainly on fat metabolism. At high intensity, the body shifts from mainly fat to CHO metabolism. The general idea of this concept is that around 65% VO2, is where the shift between fat to CHO metabolism occurs. If a person trains for chronically, this shift will occur later on. Horowitz and Klein (2000) reported that prolonged exercise has been shown to increase the fat oxidation during submaximal exercise. Several factors that Horowitz and Klein found were: an adaptive response in the muscles where there was an increase in mitochondrial density, increase of capillaries in the muscle, increase in carnitine transferase and an increase in fatty acid binding protein. With an increase in mitochondria density allows more of the fatty acid to enter into the cells and allowing the body to create energy. The increase in capillaries allows for blood to travel to the muscle quicker. With an increase in carnitine transferase, the body can increase the amount of fatty acids into the mitochondria. The increase in fatty acid binding protein, the body can regulate myocyte fatty acid transportation. A study by Martin et al. (1993) reported that after 12 weeks of endurance training, the fat

In relation to perceived exertion the subjects breathing rate stayed constant (see figure 2) because protein intake did not affect the subject’s performance and output. In other words, the hypothesis was proven to be true because protein intake did not affect the subject’s ability to perform in the final beep test, which is why the score obtained only had minimal changes from the beep test before the protein intake. Even though increased protein did not affect the subject’s performance, it was still used during recovery, which is why the subject could recover from dry land training the night before and still fill good to perform the beep test the next day. According to Cordain and Friel (2012) protein intake throughout the day, helps repair damaged muscle tissue. Therefore, over the three weeks the subject’s body was utilizing the protein intake as source to repair any tears in the muscle tissue, which lead to a better recovery. Given the following information the hypothesis was proved to be accurate because protein intake did not affect the subject’s performance during the beep test. However, to get a better understanding of increased protein intake, there should be a study performed to estimate how much time and protein the body requires to repair damaged muscle tissue after

Anaerobic power is the body’s ability to utilize stored ATP in the muscle cells. The ATP-PC energy system generally lasts 10-15 seconds, therefore majority of the participants power during the wingate test would be applied during the first half of the test. A person who is mostly anaerobic (generally their muscles are mostly fast-twitch fibers) will have more power at the beginning of the test but a faster decline in power once ATP is consumed. Examples of this type of person would be a powerlifter or a sprinter. A person who is considered more aerobic (more slow-twitch fibers) will have less power at the beginning, however will be able to better sustain their power output, having less of a decline in power throughout the test. Examples would

Subjects began the warm-up stage where, Each subject was then given a 3 to 5 minute warm-up period on a Monark4 which involved low to moderate intense pedaling at about 60- 70 revolutions per minute which included two to five all-out sprints pedaling for four to six seconds. After the warm up period, was the recovery interval which occurred between two to five minutes used to maintain the subjects muscle temperature and blood flow to help decrease any possible fatigue that may have occurred. After was the acceleration period that was composed of two stages. Within the first stage the subject had to pedal for five to ten seconds at sixty to seventy revolutions per minute. Followed by the second stage, the subject had increased the revolutions per minute as the tester loaded the required force. The Wingate Test duration was then performed for thirty seconds of all out cycling against 7.5% body mass, with the goal of acquiring the most number of revolutions in each five-second interval. Lastly, the cool-down was performed right after the Wingate Test for two to three minutes pedaling of low to moderate

However, the build up of the lactate acid over their short bursts have a cumulative effect and thus impeding on their performance (Zachrich 2008). By implementing endurance-training styles the blood lactate onset can be delayed – beneficial to performance (Ghosh 2004). Trained individuals can perform at a higher percentage of their maximal capacity without causing blood lactate levels to rise than untrained athletes. These particular individuals train for such a performance and train at high-level intensities to replicate the competition lactate levels and their body produces adaptations combating this, e.g. removing lactate faster. Thus anaerobic threshold is the more effective way to predict endurance performance during those specific times as it is about the maintenance of the high intensities for a longer period of time without fatiguing quickly.

Maximal oxygen consumption or VO2 max refers to the single maximum oxygen consumption that an individual can utilize during graded-intensity exercise. VO2 max can be assessed through properly administered submaximal oxygen consumption test which can include exercise test modes of treadmill, cycle ergometer or step test. In an individual, VO2 max can be determined by the cardiovascular system 's ability to deliver oxygenated blood to working muscles and then the muscle 's ability to extract that oxygen from the blood and generate energy for work. Influencing factors can include genetics, decline of VO2 max with aging, and finally aerobic training can positively influence an individual 's VO2 max and overall aerobic fitness. Individuals with high VO2 maxes often have greater overall aerobic fitness, which includes high efficiency, or running economy, better glycogen storage and is often an indicator of success when completing aerobic tasks of over 20 minutes. On the contrary, a low VO2 max can predict poor overall aerobic fitness which can include cardiovascular disease and problems with transporting oxygen to working muscles. (3) In these laboratory exercise test, submaximal intensity exercises were used to determine an individual 's predicted VO2 max which allowed the assessment of their overall aerobic fitness and the ability to compare the correlations between tests.
