Essay on Step Test Lab 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.

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

A heart rate monitor could have been used instead of the manual method, which would produce a more accurate result of the heart rate measurement. (http://www.topendsports.com/testing/heart-rate-measure.htm).

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

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

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

Being knowledgeable about the heart is very important, especially if one is an athlete. This experiment is significant, because it can tell us how important it is for one to keep their heart healthy. It will also tell us how playing a sport can benefit one’s health and the well being of their heart. Our hypothesis says, if the athleticism of a person increases, then the heart rate recovery time will decrease when heart rate recovery in a function of athleticism. The purpose of this project is to see which type of athlete, or non-athlete has the best heart function.

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 effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

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.

In the chart above it has five rows each row concerning different test. The first row talks about Beats per minute; in that row it ask what my beats per minute was, gives if it is over a hundred then its Tachycardia and if it is below sixty it is bradycardia and then ask if it was normal or not. My beats per minute were a hundred and fifty so it is considered Tachycardia.

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
