INTRODUCTION

Having an active lifestyle really benefits health in many different ways, and is very important to maintain throughout the lifespan. Many people often wonder how ‘in shape’ they are compared to peers regarding “body composition cardiorespiratory fitness, muscular fitness, and flexibility” but for an athlete to feel they are fit within their sport and athletic events is based on their overall performance related fitness (Milanović, Pantelić, Sporiš, Mohr, & Krustrup, 2015).
Maximal oxygen uptake (VO2) is a measure of how much oxygen the body needs to convert the food that was eaten into the molecule needed by the body to have energy, adenosine triphosphate (ATP), it is considered the “gold standard parameters of the cardiorespiratory …show more content…
The subject then put on a heart rate monitor and the resting heart beat was recorded. The test started with the resistance set at 0.5, and the participant was to try to keep a constant pedal at 50 revs per minute. When the resistance was set and the participant was pedaling at a constant rate the time would start. The participants heart rate was recorded during the last ten seconds of each of the three minutes, then the resistance was changed, repeating 4 times. If the heart rate was not in a steady state between the 2nd and 3rd minute (difference of 5bpm) then the participant must pedal at that work rate for another minute, the table 1 shows the results from this section of the test. Protocol 3 was used to finish the test because the participants heart rate was at 95 after the first stage. This means we raised the resistance to 1.5, and another 0.5 every three minutes until the test was …show more content…
Professional football players VO2 land between 58.2ml∙kg-min-1 and 69.28ml∙kg-min-1 (Unal, Unal, Salman, Baltaci, & Mogulkoc, 2004), leaving the subjects VO2 in this study quite low. An average healthy untrained male between the ages of 20 and 40 show an average VO2 of 38.15ml∙kg-min-1 (Milanović et al., 2015), healthy 20 year olds with max heart rate also at 200, see a VO2 of 49.7ml∙kg-min-1, still better than the football player in this study (Homme et al., 1984).
Cyclist always have a much higher VO2, because that is where their focus is. They want to be able to go long distances, burst to get up hills and in order to do so, they need great oxygen intake. Cyclist average about 54ml∙kg-min-1 (Billat, et al. 2012) while well trained triathletes under 30 years of age average about 62ml∙kg-min-1 (Brisswalter, Wu, Sultana, Bernard, & Abbiss, 2014).
The results from this study did not match the hypothesis. One explanation for the differences could be related to the differences in fat versus muscle and the weight of its impact on VO2 (Angermann, Hoppeler, Wittwer, Däpp, Howald, & Vogt, 2006). Another explanation for the differences could be that there were not enough proteins, carbohydrates or lipids for the mitochondria to break down to create oxygen and help generate the energy needed. The participants mass and position on the football team could also play a big role in the

What are the fitness benefits of running? Essay

Cardiorespiratory fitness (aerobic fitness or "cardio") is the ability of your heart to pump stronger and more efficiently and your muscles to use oxygen more efficiently. As you get more aerobically fit, your heart will pump more blood and oxygen with each beat (this is called "stroke volume") and your muscles will extract (or consume) more oxygen. For instance, if you have 100 oxygen molecules floating around in your bloodstream, a conditioned muscle might consume 75 molecules, whereas a deconditioned…
