Lab Analysis

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.

1. During exercise: TV will increase. 2. During exercise: IRV will decrease. 3. During exercise: ERV will increase. 4. During exercise: VC will not change. 5. During exercise: TLC will not change.

Two intervals did show a significant shorting post exercise. Besides the RR interval, the other recorded interval which contained a marked shortening after exercise was the TP interval. To understand why the TP interval is shortened when the heart rate increases and lengthened when the heart rate slows, one must first understand what the TP interval is. The TP interval, which is the the interval between the end of the

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

The authors then share their analysis on the changes of heart rate and GSR at the many different points throughout their study.

4) Compare and contrast oscillations in heart rate observed at rest (Activity 1), during exercise and recovery exercise (Activity 2). Is the relative magnitude of the oscillations the same? Provide a physiological explanation in your answer.

P6- follows guidelines to interpret collected data for heart rate, breathing rate and temperature before and after a standard period of exercise

The average heart rates of both groups were then arranged in a comparative bar graph as shown in Figure 3. Conclusively, the average heart rate

This lab has helped me to understand that when you change a factor such as the heart rate what will happen to the other variables. The part that I found challenging was in active 2 was when I had to change the heart rate after 5 seconds. To me to be hard because I tried to time it correctly. The part that I found inserting about this lab was in the begining where you could change the stoke factor. I never fully understood how stokes where caused.

Before we began the physical activity, we measured the tests subjects heart rates after ten minutes of rest, sitting on the floor. Judging that a pulse of 60 to 100 beats per minute is seen as average (allowing room for age and physical condition to factor in), we can see that the test subjects all have what is deemed to be a normal heart rate, Tests One and Two having pulse rates in early 80s whilst Test Three have a pulse in the high 90s. This means the average pulse rate for our subjects was 87 beats per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute, showing that Test One has a breathing rate higher than expected, Test Two being only slightly higher and Test Three showing the optimum breathing rate

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

In conclusion, most of the hypotheses were supported by the data collected during this lab experiment. The heart rate was hypothesized to increase during exercise and return close to normal values during the recovery phase. Figure 1 shows that both subject 1 and 2 support the initial hypothesis. The heart rate should increase during exercise because the muscles will need a greater supply of oxygenated blood for respiration, so cardiac output must also increase. The medulla stimulates the heart to increase the rate of contraction while the heart is able to increase stroke volume.

The aim of this investigation is to observe the effects of heart rate on a vertical jump. A group of participants will run on a treadmill and once their heart rate reaches a designated point they will proceed to the vertical jump.

The purpose of this experiment was to become familiar with the electrocardiograph to help us determine the heart electrical activity. As well as, to observe how exercise and different body positions(conditions) can affect the activity of the heart.

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.
