Abstract

The title of this trial is Physiology of Exercise Laboratory and it is in the physiological systems of the human body section. The purpose of this experiment was to verify our predictions about how the body systems would respond to increased physical activity. This
test is the source to understand clearly how each of the systems work together in order to make our body function properly and effectively. The procedures involved testing three levels of exercise by having a volunteer accomplish the activities. Ten minutes of complete rest, of light walking and of a harder jogging were evaluated. The data observed was the pulse, the respiration rate, systolic blood pressure, the diastolic blood pressure and the internal and external temperature. The volunteer which achieved the task was an average size teenager with no health of physical problems. Only a normal teenager was evaluated because an average result was required. The results were examined several times during the exercise to see how the data increased and how much time it took. The more demanding activity had the highest results and all the student's body metabolic mechanisms reacted to the change of action level. The experimentation worked out well because the activities were took seriously and with effort. The data concluded that our body systems do respond to increased physical motion because the the results changed right when the level of exercise attempt was more demanding than the previous actions.

Introduction

"Metabolism is the set of chemical reactions that occur in living organisms in order to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments. This experiment measures basic body metabolic parameters:

* pulse *

* respiration rate *

* blood pressure *

* temperature and sweat *


The objective of this lab is to measure body metabolic mechanisms in response to different levels of exercise: pulse, respiration rate, blood pressure, temperature (internal and external) and sweat.
.
.

Procedures

The three different conditions of activity consisted:

* Having a student volunteer laying down at complete rest for ten minutes.

* Having a student volunteer to do a light activity for five minutes.

* Having a student volunteer to do an intense activity for five minutes.

After each activity the metabolic rates were measured as quickly as possible using: oral thermometer, ordinary thermometer, sphygmomanometer (blood pressure gauge), piece of microscope tissue (for sweat), stethoscope.

- The oral thermometer should use cover slips and/or be disinfected with mouth wash before
each use.

Materials

* A flat surface *
* A large area to move around in *
* Arm type automatic digital blood pressure monitor *
* Stethoscope *
* Mouth thermometer *
* Small pieces of thin paper *
* Plastic piece to cover thermometer *
* Other material to help the volunteer relax (blankets, pillow, ear plugs, etc.) *
* Pencil and paper to record results *

Hypothesis

● ● ● ●

The hypothesis would be that the faster the subject's pulse and respiration returns to normal, the better is the subject's cardiovascular and pulmonary systems.

Another supposition concerning this experiment would be that the subjects inhaling oxygen would return to their normal pulse and respiration rates faster than subjects who were not provided with oxygen.
