Cardiovascular Fitness Lab Report

Cardiovascular Activity And How it Influences the body.

Introduction:

Cardiovascular fitness is a form of aerobic fitness (Neporent and Egan 1997). There are many different ways of evaluating the amount of oxygen used during cardiovascular fitness and one the methods involved is called VO2 Max. VO2 Max is the maximum amount of oxygen that the body can hold. (Simon and Levisohm 1987). Cardiovascular fitness helps to improve a healthy lifestyle.

For this experiment the null hypothesis is that the intensity of the step rate test (High and Low) has no effect on the persons’ heart rate

The first participant measured her pulse rate for 30 seconds before starting the exercise. Her pulse rate was calculated to determine the number of beats per minute. She then stepped on the platform (up and down) and continued at a slow pace for 3 minutes. After three minutes of the exercise, she measured her pulse rate every minute to determine her recovery time. This process was repeated until her pulse rate returned to normal. The amount of time taken in seconds for her pulse rate to return to normal is the recovery time. The number of steps taken in a minute remained constant for both

The average pulse rate after the test was 27 heart beats per minute. The SEM of the pulse rate before the test is +/-3.3bpm, while the SEM after the test is +/-4.5bpm. In test two the participant did the step test at a faster pace, also looking at the results from figure 2, we can see that the pulse rate (measured in beats per minute) before the step test is much lower than the pulse rate of the individual after the step test at a faster pace. An increase can be observed looking at the average which is 44 heart beats per minute after the step test. The SEM of the pulse rate before the test is +/-4.2bpm, while the SEM after the test is +/-10.1bpm.

The mean recovery time (which is measured in minutes) is also compared. The slow steppers had an average recovery time of 2.3 +/-0.42, whereas the fast steppers had an average recovery time of 3.75 +/-0.44. The difference in the recovery rate between the two groups is
