Pasco Exercise Report

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.

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.

The beep test is the subject received a score 13.5, this meant that the subject covered a distance of 2460 metres and ran for a period of 13 minutes and 2 seconds. Their starting heart rate was 110 and they reached a maximum of 197. Lastly their final rate of perceived exertion (RPE) was 9 meaning they found themselves working ‘really, really hard’ and at maximum intensity at the completion of the test.

The range of normal resting systolic BP for the subjects in this experiment is 115-125 mmHg. Did systolic BP increase, decrease, or not change with exercise?

Using the lab activity, observe and record the physiologic changes that occur during exercising using the following chart:

The heart rates of participants was tested before the step test, one minute, two minutes, and three minutes after the step test was performed in this experiment. Since heart rate increases while someone is performing physical activity, it was expected that heart rates of the students would be higher than before the step

Once the thirty seconds was up, the person counting stopped and the heart rate (beats per second) was recorded. The same process was done again, but the counter counted the hearts beats for 1 minute. Again, after the 1-minute was up the heart rate was recorded for 1 minute. The same process was done again for 2 minutes, afterwards being recorded.

The controlled variable included the exercise bike and heart rate monitor. There are several limitations, systematic and random errors that should be considered when interpreting these results. (4) The controlled variables were not tested before this experiment to see if they were working and reliable. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor. A systematic error could include the fitness of the participants. One of the test subjects is an endurance athlete and the other does not compete in any sport. This would affect the results because for the endurance-trained athlete, from their training they increase their cardiac output results from a substantial increase in maximal stroke volume. In untrained persons, cardiac output increases in response to exercise primarily by an increase in heart rate. The endurance-trained athlete does so mainly by an increase in stroke volume. Simply meaning that although both participants are doing the same cadence and length the endurance athletes skewers the results by already having an increased rate in stroke volume. Another systematic error may include the rate of perceived effort. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at.

I will have two groups both containing 5 people, in total 10 people all are males, one group contains people who practice an aerobic exercise on a daily-basis (soccer and basketball), while the other group contains people who do not practice an

Aims - This study is to ascertain, if there is an effect on heart rate after exercise. This is being done to see, if there is a difference between resting heart rate and heart rate after performing exercise.

= * The results will then be recorded of the resting pulse rate and placed into my results table. * One-minute star jump exercise will begin.

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.
