The Harvard Step test

Extracts from this document...

Introduction

Tom Hazell Planning: * Firstly we found a bench that was 15 cm high. * Then we set up a table allowing us 3 different results from 5 different people. * The variable we used was changing the people doing the step-ups. * We stepped up onto the bench every 2 seconds (every odd number you stepped up and every even number you stepped down) for 300 seconds (5 minutes). * After I had done the step-ups for five minutes I rested for 1 minute then took my pulse for 30 seconds. * After another 30 seconds rest I took my pulse for 30 seconds again. * And after another 30 seconds rest I took my pulse again. * As there were 5 people in my group each person repeated this process until we had 5 people's 3 pulse counts, which we put into a table. ...read more.

Person BPM count 1 BPM count 2 BPM count 3 Fitness Person 1 90 92 88 55 Unfit Person 2 62 66 64 78 Fit Person 3 64 62 60 80 Very fit Person 4 76 74 72 67 Fair Person 5 72 60 58 78 Fit Analysis: In conclusion to the experiment I would say that someone who is unfit would have a very high recovery time after doing exercise, in contrast to a fit person whose recovery time, would be very low. This means that their pulse wouldn't take very long to get back to normal. This is illustrated in the high BPM after 2 minutes of person 1 in our experiment. It shows that his heart is working very hard to try and pay back the oxygen it couldn't provide to the muscles during the exercise. ...read more.

Conclusion

* I believe that we had some anomalous results for example a person who we believed to be fairly fit got 55, the lowest result recorded, so there is room for human error in taking pulses etc. * We could have done another experiment for another length of time to see if the time affected the pulses and the overall fitness. * We could have taken the results from different groups of people e.g. smokers, older teenagers, fitness people and the 'older person' as these people would have different levels of fitness according to their lifestyle. Overall however I feel that in the allotted time we have come up with a satisfactory conclusion for the amount of people we had and the results that we had. The results apart from one anomaly seemed reliable and accurate. ...read more.

  2. Factors Affecting the Fitness of an Individual

    The blood also plays an important role here. As you get old, the Oxygen carrying capacity of the blood also reduces. As a result less Oxygen reaches to the muscles. And as a result the muscles start respiring anaerobically. This further produces lactic acid in the muscles.
