Plan & Aim

The plan and aim of this project is to select a group of six people and record their blood pressure, temperature, pulse and respiration whilst at rest. When they return from a brisk walk I will then record the same observations and analyse, evaluate the results. With this information I will then draw my conclusions and make recommendations.

Topics under Investigation

The effects of exercise and the change in the vital signs:

Aerobic exercise gets the heart working to pump blood through the heart more quickly and with more force than normal. As blood is pumped faster, it must be oxygenated more quickly, which quickens respiration. Aerobic exercise strengthens the heart.

Arteries carry oxygenated blood away from the heart to the tissues of the body; veins carry blood depleted of oxygen from the same tissues back to the heart. The arteries are the vessels with the "pulse", a rhythmic pushing of the blood in the heart followed by a refilling of the heart chamber. Low impact aerobics include walking and swimming. Running, tennis and squash are high impact aerobics.

Vital Signs

The Vital signs are: the blood pressure, temperature, the pulse and the respiratory rate.

The measurements known as the vital signs together give a very helpful picture of the person¡¯s physical condition.

The Blood pressure:

Equipment needed:Sphygmomanometer and a stethoscope.

The purpose of checking blood pressure is to obtain information on the body¡¯s physical condit...

...I took note during the exercise that a respiration rate below 12 per minute or above 26 per minute was abnormal. In the chart below I show how the respirations increase after exercise. The respirations increased during the exercise before slowly returning to its natural resting rate after the exercise. .

Conclusion

Although I believe that my experiment produced fairly valid results, an actual 'pulse-meter' might have helped the experiment to be more accurate and I could have checked the pulse rate during the exercise. I believe that this would produce a more accurate pulse rate. I would recommend to the smokers to give it up as this will increase the blood pressure. The samples of people that I used in this experiment all seem to be reasonably fit and their results show this. It would do no harm if sample 2 gave up smoking as it would reduce her blood pressure.
