Effect of X activty on the pulse rate and blood pressure of a human being.

Introduction

Effect of X activty on the pulse rate and blood pressure of a human being The goal of this lab report is to find out what has a greater effect on blood pressure and pulse rate. In order to find out, my team mates and I decided to do three exercises that would call for a great need of energy- thus a lot of blood pumping activity. Running for fifteen minutes, push ups, and sit ups were the three chosen exercises. These three exercises worked different muscles in different ways; thus we assumed they worked the heart in different intensities as well. I predict that running would be the exercise causing the heart to work more as the legs have big muscles and if they are used at a high constant rate for an elongated time, they will require a lot of oxygen- a lot of heart pumping. Running necessitates a lot of time, so we decided to do in the afternoon and we did the push ups and sit ups in the mornings. The tools used for this lab were our bodies, and a blood pressure measuring machine. ...read more.

Middle

One thing that we should've changed right at this point was to do all the exercises in the same time- either morning or afternoon. The running had the most drastic effect on the heart- the pulse rate jumped from 70 to around 125 (for Yuval and Bakor) and from 91 to 145 for Ralph, as we will observe later, it is a greater difference than has been observed from push ups or sit ups. After running Ralph had the greatest systole reading and pulse rate, Bakor had the greatest diastole. As for the two sets of 30 push ups per participants-the pulse rate rose naturally rose from the control measurement reading. Ralph had the greatest difference jumping from a 91 beats per minute (BPM) to 121 BPM. Strangely enough the systole and disastole dropped from the control measurement on the readings for Yuval. Bakor had the highest systole and diastole, and Ralph had the highest pulse rate (121 BPM). In the second try of this same exercise the pulse rate rose higher than it did the first time on average. ...read more.

Conclusion

The other problem that came up was discussed earlier : how to measure the pulse rate and blood pressure after having run considering the subjects only had one machine to use. While each subject was waiting they had to keep moving in order to keep the pulse rate and blood pressure at the same level. The running should've been performed with more than one machine and more times in order to have more secure measurements. The diet that the subjects had before the exercise could've affected the results- caffeine, sugar or a chocolate bar could've affected their performance: depending on the diet either for better or worse. As a follow up experiment scientists should have a subject question that is much more precise; so that it leaves very little space for errors. If it called for one specific type of person to be subject to the experiment results would be more precise. More time should be available in order to provide more "wiggle" space for the scientists to be more flexible with the subjects. If all the subjects of the experiment had the same treatment regarding sleep, diet and physical state the results would be much more precise. ...read more.
