Investigation to see the effect of exercise on pulse rate

Introduction: This experiment tests the effects of exercise on pulse rate.

Pulse rate represents the beating of the heart, specifically the ejection of

blood from the left ventricle to the general circulation of the body.

Before the start of exercise, your pre-exercise heart rate usually rises

above normal, and this is called an anticipatory response. During

exercise, respiration increases based on the amount of activity being

done. When exercise is being completed, there is an increased demand

for gas exchange, due to the circulatory system being under continuous

stress. Oxygen consumption increases rapidly, aswell as carbon dioxide

production.

Regular exercise also produces changes in circulation. The blood flow to working muscles increase, and this means that more oxygen and

energy can be delivered to the muscle cells. Blood volume and the

number of red blood cells also increase with this large flow, and oxygen

levels rise considerably.

In our experiment we have decided to test
