The graph of oxygen uptake vs time taken to run 1.5 miles has a negative linear association. As oxygen uptake increases, the time taken to run 1.5 miles decreases. This is can be seen through the gradient which has a value of 0.1705. This means that as the oxygen uptake increases by 1 ml/kg the amount of time taken to run 1.5 miles tends to decrease by approximately 1.7 minutes. The graph has a moderate relationship because the data is scattered in a wide band along the line of best fit. This is backed up by the correlation co-efficient (r) which has a value of -0.6 indicating a moderate relationship. The line of best fit can be used as a model to make predictions. I am going to use my model to predict the time taken to run 1.5 miles for a male with oxygen uptake of 54 ml/kg. y = -0.1705x +18.504
y = -0.1705(54) +18.504
= 9.05 minutes
My prediction is that it would take approximately 9.1 minutes for a man with 54 ml/kg oxygen uptake to run 1.5 miles.
Oxygen uptake (or VO2) is a measure of the volume of oxygen that is used by our body to convert the energy from the food you eat into the energy molecules, called adenosine triphosphate (ATP), that your body uses at the cellular level. VO2max (or maximal oxygen consumption) is simply the maximum possible VO2 that a given person can achieve. VO2 and VO2max are important in the context of exercise, because they are a measure of your body's ability to generate ATP, and ATP is the energy source that allows your muscles to continue working while you are exercising. Therefore, by definition, a VO2max measurement is ultimately a measure of your cardiorespiratory fitness level so this information would be useful to trainers who want to know how much oxygen uptake their athlete needs to have in order to run a certain amount of miles, so that they can increase of decrease the oxygen uptake as needed. The research that I have found backs up my calculation and prediction that when the oxygen uptake...
