Heart Rate Lab

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

Controls- The control in this experiment was very important because if it was not contained, then the data would have been faulty. It was very difficult to keep

Once the patient was correctly hooked up to the EKG the BIOPAC Student Lab Program was started. Lesson five is the one we used for this experiment and once it had been chosen we label it and started the experiment. There were four conditions we needed to measure; the first being lying down. The subject was lying down relaxing on the cot. We clicked record and let it run for 20 seconds. The data resembled the chart below. If it did not we would have had to repeat the steps until it did.

The experiment was conducted by a number of individuals to see how the effects of a substance would have an effect on a Daphnia. The Daphnia’s were placed in multiple different substances environment to see the effect it would have on their heart rates. When doing the experiment the first step was to take the Daphnia and put it a Water solution to observe the heart rate of the Daphnia and record the heart rate. Recording of the heart rate were taken for when the Daphnia were in the Water solution that way they could compare with the next solution which was Caffeine.

Hypothesis: If the body moves back to normal position from squatting position while the time limit and squat angle are all relevant in all three trials, then the heart rate will balance in 10 seconds because the baroreceptors will start the feedback mechanism and will quickly rebalance the heart rate?

8) The treatment was compared and the effect of each treatment on the heart rate was explained.

This paper explores and explains the findings of the heart rate experiment conducted by the students of Grand Canyon University for the Anatomy and Physiology 202 Laboratory course. Over a two week time span, students were asked to record their heart rate, before, during, and after activities as instructed by the professor. Specifically, this paper focuses on the female students, comparing the heart rates of individuals who reported that they drink coffee versus those females who reported that they do not drink coffee. The effects of caffeine contained in the coffee were examined and it was noted that those who drink coffee have lower heart rates before, during, and after times of examination. These findings suggested that the hypothesis proposed prior to research, Females Who Drink Coffee Have a Higher Heart Rate Prior to Exams, was an incorrect statement.

8) Make a graph of heart rate and breathing rate (please put both sets of data on the same graph) versus time after exercise. (from lab paper)

This experience consisted of 20 subjects from Woden plaza varying of age and gender. It also included one student who was going to conduct the experiment.

The ACh was a stimulant. The five-hour energy was a stimulant. The aspirin was a depressant. The diet pill was a stimulant. The substance with the strongest effect was the Adrenaline. The group’s predictions were all accurate according to the data we obtained in this lab. Doing this lab was a great way to learn what these substances do to your heart and your body. These results could always be from a human error but the group was confident with the labs result. The group was confident that the lab was done correctly and efficient. One of the issues the group could have had is the amount of time we had to do the lab and it was hard to keep up with the Daphnia’s heartbeat. Another human error could be that we put too much of the substance on the Daphne and didn’t keep a close eye on the stopwatch. For further research we could always test different stimulants and

In conclusion, this experiment was successful. The purpose of the experiment was to observe the change in heartbeats per minute before and after a physical activity, in this case, ten jumping jacks. As predicted, the data proved that the hypothesis was correct because you can clearly see in the graph that the heart rate after exercise was higher. One point that I noticed from the data was that the ten jumping jacks affected the subjects differently. Subject two’s heart rate after exercise was significantly higher than subject one’s. Subject one’s heart rate increased only slightly; whereas subject two’s heart rate increased significantly. This experiment is a good basis for additional testing involving heart rates and exercise. If this investigation

For example, Test Three commented that they were feeling nervous and stressed about an event occurring around the time of the investigation being carried out, and that they in particular moderated and controlled their breathing during their exercise to prevent an asthma attack. It is true that due to the uncontrollability of many factors, many of the controlled variables that could have impacted the experiment may have had an effect on the final results. These factors include varying levels physical fitness capability, existing medical conditions (e.g. hay fever or asthma, which both Test One and Three suffer from) and the different time of day and weather conditions (Test One and Two performed the experiment in the midst of a hot afternoon, whilst Test Three had to conduct the experiment in the late morning when the weather conditions would have been cooler, less sunny). Taking these into consideration, whilst the results still prove the hypothesis, the validity and reliability of the results must be questioned, as these results will ultimately have an impact on the heart rate and breathing rate of each individual, as all would understandably react to the different conditions in different ways. We do believe that though these factors would have had some level of effect on the test patients as they each react differently to these exhibiting factors from external and uncontrollable variables, they would not have had such a significant influence on the recorded results to deem this investigation faulty or invalid.

At the beginning of the experiment, all rats will be restricted to a condition of no exercise for 4 days, where their baseline reactions and levels of stress hormones will be recorded. After that initial period, rats will be subject to their specific levels of daily exercise and the results of tests performed will be compared to the baseline that was recorded previously for that specific rat. This will help account for individual differences in each rat, as some may have naturally higher or lower levels of stress. A select group of rats will also continue to have no exercise, just like at the start of the experiment. This will help give an idea as to what level of change observed is just caused by time spent in the lab and the controlled environmental conditions that all rats will be subject to. All rats, regardless of their experimental condition will individually be housed in the same type of cage, and receive the same type and amount of food and water. Again, this is to help control for any confounding variables that may affect the stress levels of the

This experiment and many others that follow within its footsteps can be used to help those who

The part of the method went really well was that we made steps for recovering time.. The recovering time was very important for our experiment, and it took the most part of the experiment.
