Heart Rate Lab

1a. The scatter plot graph is showing the average heart rate change over time for the class data. From the graph, we can observe that for the control data it is mostly a steady line. Then for the test data, we can see that it starts up high then decreases, and then up again, down, and finally back up.

1b. The bar graph indicates that after the activity was performed there was an increase in all the group’s test heart rate except for 1. That one group had a decrease in heart rate because they performed a breathing exercise which caused a decrease in heart rate. For all the other groups you can see that the test heart rate bar is always higher than the control heart rate. We can conclude that any stress on the body activities causes an increase in heart rate, we see this in the exercise that did 15 jumping jacks had an average control heart rate of 77.3 and an average test heart rate of 94, which is an increase of 16. 67 beats per minute.

2. The graph above depicts the average change in heart rate in accordance with the action. From the data, we can indicate that all the groups had an increase in heart rate after the action performed except 1 group. Everyone’s exercises except one group included adrenaline rushing activities like 15 jumps, scary movie scenes, sit-ups, and EDM songs. The other group was different because their data showed a decrease in heart rate and their activity was holding their breath for 15 seconds. After looking at the graph you can notice that the heart rates are scattered far away from each other which can mean that this isn't the most accurate experiment because everyone’s health is different meaning different heart rates.

3. The question that my class and I observed was how is heart rate changed after an action? After thinking about the question we came up with a hypothesis, which stated if one performs sit-ups then one’s heart rate will increase because they’re taking part in an action which increases the amount of oxygen needed to perform that activity wrestling in an increase in heart rate. For my group’s experiment, we chose to do sit-ups. This activity caused an increase in heart rate from all group members. Other groups choices varied from scary movie scenes, EDM songs, holding your breath for 15 seconds, and finally doing 15 jumping jacks. The one activity that caused the largest difference in heart rate was performing the 15 jumping jacks. The average control heart rate was 77.33 and the average test heart rate was 94, which was an increase of 16.67 beats per minute. This increase in heart rate can be explained, when your heart can’t

Anthony Parafati Lab Questions pump enough blood to the rest of your body causing a need for more oxygen which increases your heart rate. There was one group where their activity caused little change in heart rate. The activity that they did was watching scary movies and had an average control heart rate of 72.33 and an average test heart rate of 73.92, which is an average change of 1.59 beats per minute. I believe the group got a little change in heart rate because the scary movie scenes might not have really scared the participants. They might have known what happened already in the scene or might have just not been scared by these scenes. My group’s data showed an increase in heart rate change by all members. The average control heart rate was 70.17 and the average test heart rate was 89.92, which is an increase in heart rate of 12.58 beats per minute. Our hypothesis was correct because the data states that there was an increase in heart rate after the sit-ups were performed. In conclusion, the data we came up with states that performing sit-ups will increase your heart rate because your body needs more oxygen and an increase in the heart to perform the activity, resulting in an increase in one’s heart rate....
