Comparing Fitness within a Group
The task is to compare our fitness within a group, to find out who is the fittest and the most unfit in the group. There are 3 people in the group, me (Luke), Sam, and Donald.
The three components of fitness I will test are:
- The resting pulse rate (rPR), generally the lower this is the fitter you are.
- The change in pulse rate from when you move from the prone position to the standing position. In a perfectly fit person this should not change.
- The recovery time after 2 minutes exercise. The quicker the recovery time the fitter you are.
We are testing these because these all generally give you a good idea of your fitness level. We are testing the recovery time because it gives a good indication to how well your physiological mechanisms respond to stress. I will use these components and the following methods because when you exercise the body demands more oxygen for the working muscles to produce energy and continue working. Therefore the heart rate will give a good indication of your fitness because if it doesn’t raise much it means you don’t need as much oxygen because you can already cope with the demands of the exercise. The fitter you get means you can pump more blood per beat and therefore minute which means you will not have as many beats per minute because you’re already pumping enough blood to cope with those certain demands.
