Investigating the Effect of Exercise on Pulse Rate

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 predict that there will

be a gradual increase in both the smoker and non-smokers pulse rate as

the body begins to work harder the heartbeat is forced to increase,

therefore the heart rate will increase.

There are several factors as to why I predict that the heartbeat will

increase in a smoker and a non-smoker. Due to the toxic...
