Heart Rate Lab Report
Introduction
In this lab, I looked at how exercise affects a person’s heart rate (BPM), systolic pressure, diastolic pressure, and Mean Arterial Pressure (MAP). Heart rate is measured by beats per minute while systolic and diastolic pressure are measured by millimeters of Mercury. I found the MAP by the following equation, MAP= Diastolic Pressure + ⅓(Systolic-Diastolic). We found out that heart rate and systolic pressure were highest right after and during exercise, while diastolic pressure and MAP were higher when the test subject was 2+ minutes after the exercise.
Procedures
In the lab group, we chose one person to do two types of exercises, jogs and jumps. We measured the Heart Rate by counting how many times the test subject’s heart pumped per minute. We measured systolic and diastolic pressure with a sphygmomanometer. At first we …show more content…
After those two exercises we waited in increments of two minutes and measured heart rate by counting heart beats every minutes. After that we also measured (as I said before) the systolic and diastolic pressures through sphygmomanometer. Finally, we plugged those numbers into the MAP equation and got that.
Results and Answers
The experiment went as expected with the results being that heart rate and systolic pressure sky rocketed when exercising and the farther away from exercising it got smaller. When resting, the test subject had a much lower HR and SP because the heart wasn’t pumping a lot of blood to meet the needs of oxygen from exercising. Diastolic Pressure and MAP stayed the same significantly over time but the DP gradually increased towards the end. Our main result was when HR and SP were high the DP and MAP were low and vice versa (for their specific number ranges). This is because when exercising the oxygen tissues need much more hemoglobin (which transfer oxygen) which in return makes the heart need to pump out more blood and which raises the pressure (systolic pressure). When resting
