Carbon Dioxide and Respiratory Rate
Transcript of Carbon Dioxide and Respiratory Rate
-If our hypothesis is correct, then by doing exercises, the subjects will not be able to hold their breath as long as they could prior to doing exercise.
-Because men have a greater lung capacity than women, the male subjects will have greater duration times than the female subjects regardless of athleticism.
1. Each subject will take 2 normal breaths before holding their breath.
2. Each subject will take 2 normal breaths and complete 25 jumping jacks. Next, they will take 2 normal breaths and then hold their breath.
-Subjects will hold their breath at rest.
Does an increase of carbon dioxide levels in one’s body affect his or her respiratory rate?
Carbon Dioxide and Respiratory Rate

During the summer, people are more active. Activities such as exercising, canoeing, biking, and swimming, are just few actions we oftentimes execute in addition to our busy, day to day schedules. Exhausting so much energy can potentially yield negative effects if we do not judge our physical states carefully. The more our bodies refrain from being at rest, the greater the buildup of carbon dioxide becomes within our bodies. Too much carbon dioxide and not enough oxygen can affect our respiratory rate, ultimately causing difficulty in breathing.The following experiment tests the ability of an athletic and nonathletic adult male and female to hold their breath at rest and after exercise. The addition of exercise assisted in understanding the correlation between CO2 buildup and respiratory rate.
-Subjects will hold their breath after exercising.
The duration in which each subject can hold his or her breath will be measured.
subjects were tested in this experiment; two males and two females.
None of the subjects involved have a history of tobacco use, asthma, or any other upper respiratory conditions.
Two of the subjects are athletic (one male, one female) and two are nonathletic (one male, one female).
This protocol was done once by each subject. However, this experiment is repeatable.
The increase in the CO2 level decreased the amount of time each subject could hold their breath.
Despite men having a higher lung capacity than women, the duration times for each female subject were greater than each male subject's.
Can we make the experiment better?
Yes, there can be a change in the controlled variables that were used. Each subject should be required to stand upright in one position with both hands at their sides.
The protocol could have been repeated to attain more accurate data.
The temperature of the space in which the subjects participated in this experiment was very cold. Also, the jumping jacks exercise can be substituted with running.
Another way in which this experiment can be done is by having two subjects do jumping jacks for one minute while the other two subjects run for one minute and then compare the data between the two exercises.
The noise levels around the subjects can be controlled more efficiently. There were moments in which the subjects had the urge to laugh which may have affected the duration of them holding their breath.
Overall, carbon dioxide levels have an effect on one's respiration rate. Based on the experiment and the data recorded, subjects had a greater urge to breathe after completing the 25 jumping jacks.
The males were tested first in this experiment.
During the experiment, each female subject stood upright in a solitary position with both hands at their sides when holding their breath.
Neither male subject stood in a solitary, upright position when holding their breath.
The athletic male subject leaned against the wall at one point and he also leaned over at one moment.
There is a probability that both females had greater times because their technique was more structured than the males.
