For persons 1-3, as predicted, the heartrate and breathing rate were relatively low with Person 1, respectively, being 74 & 20, Person 2 being 86 & 16 and Person 3 being 73 and 19. The 50m Sprint resulted in having the highest heartrate for persons 1 and 2, 152 and 171 respectively, and the Stairs resulted in being the highest for Person 2 at 130. Strangely, the breaths per minute for persons 1 and 2 were highest, at 40 and 39 respectively, whereas Person 3 experienced their highest breaths at 43 for the 50m Sprint, which coincides with their highest heart rate. These trends show that the hypothesis is correct in the sense that the heart and breathing rate did increase with physical exercise, however, the hypothesised theory that the Sprint …show more content…
When exercise is undertaken more oxygen is used for the necessary organs, therefore resulting in CO2, once a gas exchange has occurred. When put under stress the body responded by increasing the heart rate, by enlarging the arterioles and venules to allow more oxygenated blood to flow to the necessary muscles and decreasing the size of ones that weren’t as important. In order to keep up with the demand for oxygenated blood, the breathing rate increased drastically. The method was relatively effective for recording the necessary data. However, some modifications had to be made such as: the amount of laps on the stairs. This changed to two laps, as once was believed to not provide enough varying data. The method could have been improved by ensuring that, once completed, the person performing was at or very close to their resting heart and breathing rate before commencing the next exercise as this would be one factor in providing inaccurate results. Another improvement is that, rather than running a certain amount of time (stairs), the person would run for a length of time and then test their heart and breathing rate as some people may not finish, and therefore put their body through enough stress, to provide difference within their
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.
Before performing this experiment we hypothesised that breathing exercises would cause the heart to relax, causing a decrease in heart rate and blood pressure. In addition, we predicted that the systolic pressure would decrease and the diastolic pressure would stay similar to the control test. Due to all of the three t-tests exceeding .05 (0.64659, 0.380067, 0.184003) the null hypothesis was accepted. The data didn’t show a significant change from the basal readings to the treatment readings so we failed to reject the null hypothesis.
In this assignment I will be introducing a formal report that is based on an investigation into how the body responds to exercise and which analyses the results from the investigation. The investigation involves myself and other pupils in my class. I will be doing the Harvard step test. the other pupils in my class will be monitoring my heart rate, breathing rate and temperature before and after the test.
In addition a small rise in breathing rate and this is called anticipatory rise, this happens when exercising. The average reading for breaths per minute during exercise is 23-30. This shows that with more blood pumping through the body more oxygen is needed to keep the body at a sustainable rate to help our body create more energy. Our breathing rate will keep increasing until
After the exercise, we then took the measurements of our pulse, breathing rate and temperature too to see the change. Once we had completed this the first time, we then did it 2 other times, so in total 3 time so that the data was reliable and trustworthy. (Stretch, B., & Whitehouse, M. (2007).
The effects of heart rate on differing durations of exercise were studied in this experiment. For people, heart rate tends to increase as they perform physical exercises. The amount of beats per minute gradually increases as people perform physical activities. Heart rates taken before exercise are relatively low, and heart rates taken one minute after exercise increase significantly. Heart rates slowly begin to decrease after they are taken two minutes and three minutes after performing the step test, which is to be expected. The rates of intensity throughout exercise relates with changes in heart rate throughout the step test performed in the experiment (Karvonen 2012). The age of the participants affected the experiment, since the heart rate during physical exercise, in this case the step test, is affected by age (Tulppo 1998).
Furthermore, the results showed a common trend of heart and breathing rates before, during and after physical activity, proving our hypothesis that heart rate and breathing rate increases during exercise, and whilst various external factors may have impacted the results taken, it must be noted that overall
Purpose: The purpose of this experiment is to determine whether athletes or non-athletes will recover faster in a span of 10 minutes from an increased heart rate after running one lap around the track. Extra Research: To determine what a subject’s heart rate should be after exercising, the “target heart rate zone” was discovered through research. The target heart rate zone can be determined by calculating 50% - 85% of the subject’s maximum heart rate, which is their age subtracted from 220 BPM. Hypothesis: If five athletes and five non-athletes run one lap around the high school track, the heart rate of the athletes will recover faster because their heart rate will resemble their resting heart rate more after 10 minutes, in comparison to
The purpose of this experiment is to show how the cardiac and respiratory system react after exercise. Each system differs at rest and after exercise. We observed the respiration rate, the blood pressure (bp), and our pulse during resting and after exercise. Everyone exercised for five minutes. We chose to run a flight of stairs in the same building of our class. After exercise we would check off everything that we listed to see the bp, pulse, and breathing. To check our bp and pulse we used an electronic cuff called the sphygmomanometer to do our counting. Once we completed our exercise we would each have a two-minute break. For that break we would recheck on the new differentness and check how much has changed from before exercising and after
Person X’s heart and ventilation rate was normal before the test because they had not begun exercising and were at a resting rate. The reason their heart and ventilation
The hypothesis was supported, if the exercise is more intense, then there will be more cell respiration because during exercise, ATP is used up more rapidly; at a resting state ATP is produced at a steady rate but when the body uses more energy than what is being produced, the cell needs to respire at a quicker rate to provide energy to the body. In a resting state, the average heart rate was 74 beats per minute, the average breathing rate was 9.5 breaths per minute, and the average carbon dioxide production times was 34.085 seconds. After a period of running, the average heart rate was 124 beats per minute, the average breathing rate was 24 breaths per minute, and the average carbon dioxide production times was 6.0875 seconds. The data shows
For this experiment we strived to answer whether or not the type of exercise affects heart rate? We predicted that heart rate will increase slower when a human test subject is doing sit ups compared to burpee’s. Our null hypothesis stated that the heart rate will not change when a human test subject is doing sit ups compared to burpees. We conclude with all our data that Burpees increase heart rate faster than sit ups do, and that the type of exercise does affect your heart rate. The slope of the burpee best fit line was clearly higher than the sit up one.
Heart rate is expected to increase during exercise. The reason for this is that the muscles in the body are demanding more blood and, essentially, the heart must work harder in order to provide for the muscles’ needs. Athletes, who are more adapted to exercising environments have a lower maximum heart rate than individuals who do not exercise as frequently. In a study done between two groups of individuals – one containing only athletes and the other containing individuals who had performed any type of exercise in the previous 6 months – results showed that athletes had a lower heart rate when they performed exercise than non-athletes (Martinelli 2005). The reason that athletes have a lower maximum heart rate is because the heart can pump blood to the rest of the body more efficiently – in larger amounts – than it would in a non-athlete.
The results of this test show that it provides a valid test to estimate aerobic capacity and shows there is a small measurement of error. A polar heart rate monitor was used to measure the heart rate with a step of 30cm in height with a metronome with a beat at 15 steps, per minute and increased by 5 steps every minute for 5 stages or until 80% of the maximum estimated heart rate was reached. The results demonstrated that the Chester Step technique is a valid predictor of aerobic capacity in males and females from a wide range of ages and fitness levels.
As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.
