Light Exercise Lab Report
Abstract The primary purpose of this laboratory experiment was to record the effects that light exercise has on different cardiovascular functions such as mean blood pressure, cardiac out put, and total peripheral resistance by comparing both of the numerical values before and after exercise. Prior to exercise, the mean blood pressure (MBP) was 86.8 mmHg with a standard deviation of 7.4. After exercise, MBP was 96.3 mmHg with a standard deviation of 9.2. The cardiac output (CO) was 5.3 Liters/minute with a standard deviation of 1.0, but the CO was 8.3 Liters/minute after light exercise with a standard deviation of 2.5. Finally the total peripheral resistance (TPR) recorded was 16.8 with a standard deviation of 3.2 at rest and 12.6 with a standard

That number was then multiplied by four to acquire the number of beats per minute, which is known as the heart rate. Next, we took each person’s blood pressure in the group by wrapping the sphygmomanometer tightly around the person’s upper arm right above the elbow, while pressing the stethoscope against the anterior crease of the elbow. The blood pressure cuff was inflated to 190 mmHg. Afterwards while releasing the pressure slowly, the group member that is using the stethoscope listened for the Korotkoff sounds. The first sound you will hear are labeled as the systolic pressure, and the second sound you will here is labeled as the diastolic pressure. Then, the mean blood pressure (MBP) was calculated using the following formula: mean blood pressure (MBP) = 2/3 (diastolic pressure) + 1/3 (systolic pressure). Cardiac output (OP) was then calculated by using the formula: (CO) = stroke volume (SV) x heart rate (HR). Stroke volume could not be found in the lab, therefore, we used a standard set of experimental purposes: If the student’s weight was less than 150 lbs., then the SV= 0.070 L/beat at rest and SV= 0.100 L/beat after light exercise. If the student’s weight was over 150 lbs. then the SV= 0.085 L/beat at rest and SV= 0.110 L/beat after light exercise. Heart rate was recorded in the first step of the experiment. After those values were calculated, the total peripheral resistance (TPR) was determined by the following formula: TPR= MPB/CO. These steps were preformed prior to exercise and again immediately after following light exercise, which consisted of a fast paced walk or a jog from Gouaux Hall to the library and
