Investigating the Effect of Exercise on Pulse Rate

Aim: To see what happens to the pulse rate during exercise.

Prediction: I predict that the pulse rate will increase in order to take more oxygen for respiration. The heartbeat will increase and become stronger to transport oxygen and carbon dioxide to and from the muscle cells. The breathing rate will increase in order to get rid of the extra waste such as Carbon dioxide. Respiration is the release of energy. Anaerobic respiration occurs during prolonged exercise as our heart and muscle use up a lot of oxygen, this prevents oxygen from being transported to the lungs quick enough. The word equation for this is Glucose---- Lactic acid and energy. I

The tar, which is found in the cigarette smoke, irritates the air passage and Carbon dioxide then reduces the ability of blood to carry oxygen through the bloodstream. I predict that the non-smokers heart rate should be smaller during exercise as they have a healthier more effective heart. Oxygen is easily pumped around the body this reduces the amount of work that the heart has to do therefore decreasing the pulse rate.

Plan: =====

*The resting pulse rate will be taken and recorded for both the smoker and non-smoker. The heartbeat will be taken by placing your two middle fingers on your wrist were your artery crosses with the bone. You must ensure that you do not use your own thumb as this contains a pulse itself. ======================================================================

* The results will then be recorded of the resting pulse rate and placed into

my results table.

* One-minute star jump exercise will begin.

* When the star jump exercise is complete I will then record the heart rate every minute using a stopwatch, until it returns to it's original resting pulse rate.

Key Factors: In order to make my experiment a safe one we had to follow many obvious rules by making sure that the area we used was open and away from other people to avoid injury to others. We made sure that proper
