Descriptive Title
In a human body, exercises significantly affect the heart rate. When exercising by climbing and descending in a staircase, the heart rate seems to change, and breathing is affected. This experiment is used to make an analysis on the ups and downs on the staircase.
Introduction
Aerobic exercise that includes the ups and down on the staircase, is an extended activity-involving key group of muscles and increased heart and respiratory rate. Stair case climbing involves some muscles such as the calf muscles and Quadriceps in the legs. It is an exercise that requires few materials and hence becomes the best heart rate experiment. With increased blood circulation in the body while exercising, we expect increased heart rate.
It extremely crucial to stretch before exercise in order to increase blood flow in the body, and in turn, it will increase the heart rate. When exercising, the rate of blood flow will increase but at a lower and steadier manner. A stopwatch, 12 or more step staircase, heart rate monitor, and a participant were used for this experiment.
The main variables for the experiment included female participants with athletic ability of 50%, one cup a day caffeine consumption, and a normal 8 hours sleep level. A lot of caution was exercised, and multiple were made during when the participant felt some pain in her muscles (Hales, 2009).
Methods
The participant’s heart rate was first measured using a heart rate monitor and the readings recorded. This was done by placing a finger on the participant’s carotid artery, which is on the neck or either on the wrist where there is the radial artery. The participant was required to count her heartbeat for about 15 seconds. The result was multiplied four times to get the heart rate per minute.
The participant was then asked to climb and descend the staircase in a quick manner and without missing any steps. The number of time ascended and descended was carefully counted and tallied down. The stopwatch was used to determine the duration of the exercise, which was to last for two minutes. The heart rate was determined three to four times upon completion of the exercise and results tabulated down.
The experiment was carried out before and after the participant stretched. Different ages were used in the experiments.
Results of experiment
1c: Exercise Data Averages for 17-year-old Participant
Discussion
The experiment was successful as the effects of the ups and down on the staircases was determined. The heart rate experiment covered participants from different ages and their result tabulated.
It has been discovered that the heart rate for adults was higher comparing to the youth and the child. This is mainly because of the heart size where it is bigger in adults and smaller in children.
