Heart Rate Lab

Improved Essays
Introduction
The purpose of the lab was to see the effects of heart rate and blood pressure when 3 male and 3 female students exercised compared to when they were at rest.

My hypothesis is that the data from the exercise part of the experiment will cause both the heart rate and blood pressure (systolic and diastolic) to increase more than the resting state.

Methods
Resting heart rate was recorded in the begging of class. Then the class was divided into groups and from each group, there was a person who was doing the exercise (cycling), a recorder/ timer, someone who measured blood pressure, and someone who measured the heart rate. The data was then written on the whiteboard for others to copy.

The experiment had each person exercising

The graph also shows which data was from females versus males. This show that the recovery heart rate did come down but not all the way to what it was when it was measured at rest.

The graph above shows the resting heart rate (Resting) compared to the exercise heart rate after the 1st workload (Ex HR 1) and after the 2nd workload (Ex HR 2). This graph shows that heart rates from rest to exercise were increasing for the most part.

The graph above shows resting systolic blood pressure (Rest SBP), exercise systolic blood pressure after the 1st workload (Ex SBP 1), exercise systolic blood pressure after the 2nd workload (Ex SBP 2), recovery systolic blood pressure after 1 minute (Rec SBP 1) and after 2 minutes (Rec SBP 2). This shows that for the most part the systolic blood pressures increased between workloads and decreased or stayed constant during the recovery. The resting systolic pressures and the 2-minute recovery systolic pressures were mixed, most of them were increases and a few

There were very mixed results from the diastolic and systolic blood pressures. Discussion
The physiological difference between male and females in heart rates and blood pressures is due to females having a slightly higher resting heart rate because they typically have a smaller heart size smaller blood volume. Hormones may also play a role. Each body is unique and different process work at different rates from person to person.

The heart rates mostly increased as workload increased. The systolic blood pressures during exercise for mostly increased. The diastolic blood pressures were very mixed with the subjects.

The heart rates from resting compared to exercise were higher. For the most part, the blood pressure rates were higher than the resting in all the subjects.

Heart rate and blood pressure should both increase following exercise.

Conclusion
Heart rate and blood pressure both increased following exercise. Recovery data did not decrease back to resting heart rate after 2-3 minutes following exercise.

    The heat rate is best defined as the number of times the heart beats per minute. The recording that was taken immediately after exercise was the condition that had the largest heart rate of 126.2BPM, while the recording that was taken while lying down had the lowest heart rate mean of 57.2BPM. Immediately after exercise had a larger heart rate due to the fact that there was an increase in oxygen, which is required for muscle to produce the necessary energy for physical activity. The other testing conditions had a mean of 71.1BPM while seated and breathing normally. As noticed from the results portion of this experiment, the recording of breathing deeply was divided into two parts: inhalation and exhalation.…

    Introduction The purpose of this lab was to determine the rate, function, and integrity of the heart during an exercise EKG. An electrocardiogram measures the electrical activity of the heart over time. In this lab a subject will exercise for about 15 minutes, not including rest times and the EKG will measure the heart’s activity.…

    Afterward, in the Bicycle Ergometer experiment, we measured these parameters again every 30 seconds while the subject pedaled at their light resistance and moderate resistance. We used those measurements to calculate the stroke volume, cardiac output, and total peripheral resistance. Lastly, the treadmill experiment, the subject was affixed with a heart rate monitor and mouthpiece while performing the experiment. The parameters include heart rate, % O2,…

    Repeat steps 2-4 for 45 seconds, and 60 seconds. Record data for each member. Repeat step 2-3, for measuring pulse. As soon as the group members stop running, each should place their finger either on their neck or wrist, and the timer will time them for one minute as they count how many beats their hearts beat. Repeat step 6 for 45 seconds and 60 seconds.…

    The results indicate that caffeine did in fact have an affect on the heart rate and so did increase the number of heart beats per minute. However, there were no significant changed that occurred in the heart rate when more caffeine was used. Since caffeine takes approximately 15 minutes to have an affect, I believe that the caffeine had not be digested or kicked in yet so I think if the results were taken at a later time the change in heart rate would be greater. Hence, this investigation could be improved by recording the heart rate at 15 minute intervals for at least 30 minutes for better results.…

She has took a fast breath about 60 second, and the tester has noticed and recognized what happen during hyperventilation. After that, the tester has recognized what happen during hypoventilation by letting the subject to breath slowly about 60 second, and take a deep breath and hold it as possible. Finally, the data was collected from the graph.…

    Exercising can help the body burn fat but it also helps the heart rate recovery. When exercising the heart rate of the body will take to increase depending on the pace of the person. When the heart rate starts working at a controlled pace doctors can find out the amount of oxygen that person is taking in. As the person starts to decreasing the pace of their exercise, that is when the heart recovery starts to kick in.…

    Problem: For this procedure we tested are heart rate to see how it changed depending on what level activity we did. Heart rate is when the heart contracts because it is pumping the oxygenated blood through the aorta. Then the blood goes through your heart through the vena cava. Once you start moving the blood go through the capillaries to your lungs, legs, head and arms the blood flows through the inferior and superior capillaries.…

    Furthermore, subjects were categorized for each variable as either normal or abnormal, non-parametric data analyses were engaged, with frequencies of normal and abnormal Signal-averaged ECG being recorded for each group. As, weight lifters and the control group undergo Signal-averaged ECG analysis at rest and following an acute bout of exercise to overall exhaustion. Signal-averaged ECGs were analyzed using a 40 Hz filter and were averaged over 200 beats. Outcomes point toward a non-significant trend for increased incidence of abnormal Signal-averaged ECG measures at rest in AS (P= 0.55). However, AS demonstrated a significantly higher incidence of abnormalities of Signal-averaged ECG following exercise than the control group or weight lifters (P\0.05).…
