Comparing Pulse Rate between Athletes and Non-athletes Before and After Physical Exercise

Introduction

The circulatory and respiratory systems (called together as the respiratory system) act together in one to enable moderate to severe exercise possible (Ganong, 2005). The capacity of adjusting by the system to exercise is called as cardio-respiratory fitness. This endurance can be measured using difference methods that have been designed and test by early researchers.

The state of the cardio-respiratory system determine the tolerance of individual to exercise. Among the measurements that are to be done to determine the godlessness of this system is the measuring of heart rate (Brehm, 2007). Heart rate is normally increases during exercise.

Heart rate definition is the number of beats that the heart is making in one minute. Generally, the normal heart rate of an adult is said be around 60 to 100 beats per minute (Guyton, 2006). Studies has shown that the resting heart rate of trained athlete is low than that of an untrained grown up with the same age. The trained athletes compensate for lower heart rate by having an increase in the strength of the beats. For this reason athletes tend to have big hearts. A lower heart rate is good indicator of tolerance of exercise of person.

Heart rate is measured by locating an area in body where it is clear. Usually this area is found outside of the wrist when palm is put to face up wards. To feel it two fingers are placed over the artery at these places. The pulse is felt when the artery is pressed on the bone (Ganong, 2005). After location of it the beats found in minute are counted and recorded. Some people likes to take it for 15 seconds and multiply the results by 4. To increase accurateness it can be taken two times and then doing average of the two results got.

Measuring cardiovascular fitness using heart rate requires the subject to take part in aerobic exercise. Athletes normally, have quick recovery than their untrained counterpart. An athlete should get a smaller increase in heart rate than the untrained person.

In order to perform this test with easiness, the step test is used. In this test the subject of the test is asked to step on a raised platform and step down at a particular rate which is already known and made. The hypothesis of the experiment sought to test whether there was a noticeable difference in the effect of aerobic exercises between the pulse rates of athletes and non-athletes.

Method and Material

The students were worked in six groups. Each group was having four members. One student was an athlete and one was non-athlete. The other two students were to take pulse rate measurements of the two test subject.

The experiment was done by first taking the resting pulse rates of two test subjects who got identified. Pulse was located at wrist and timing was done for 15 seconds and the result got multiplied by 4 to get the pulse rates in a minute. A stopwatch was used for this timing.

After resting pulse rate has been measured, the two test subjects were asked to do a three minutes step test. The subjects were asked to climb up and come down the platform for three minutes using rate of 30 steps per minute. After the step test, pulse rate located. The rate per minute was calculated from the figure for 15 seconds of timing.
