Heart And Breathing Rate M/F Before And After Exercise
Science:
Abstract:
This investigation is to show the raspatory and circulatory systems in deeper meaning. It also explains the reasons for why breathing and heart rate becomes higher during physical activity, and if there are any differences between female and males.
This experiment shows the biological principles, and how to record and produce data of a quality standard.
Introduction:
Air goes into the alveoli when we breathe in. This lets the veins around the alveoli drop of their carbon dioxide and pick up oxygen. The oxygenated blood travels around the body and drops of oxygen to cells and picks up carbon dioxide. It travels back through the veins through to the heart and then to the lungs again and repeats the progress. Cells use oxygen and produce carbon dioxide when being more active.
The subjects were moving to make their cells become more active. The reason for this was to find how this effected the heart and breathing rate. The subjects were separated into male and female to look for a difference between the genders breathing and heart rate.
Hypothesis:
1. The rate of heartbeat decreases as physical activity increases.
2. The rate of breathing increases as physical activity increases.
3. Females have a higher rate of heartbeat at rest than males of the same age group.
Materials:
Stop watch
Pencil and paper
24 subjects
Running area with a slope
Method:
1. A heart rate was recorded from all subjects after resting for 5 minutes. The heart rate was taken counting carotid pulse by using two fingers on the subject’s neck where the pulse is for 30 seconds, then multiplied the count by two.
2. The subjects resting breathing rate was recorded by placing two fingers under their nostrils and counted the outward breaths for 30 seconds...
