A INVESTIGATION ON PULSE RATE

Aim: - To investigate the effect of exercise on the heart rate.

Hypothesis: I think that when the length of exercise increases, the number of beats per minute will rise. The number of beats per minute will rises steadily because the amount of exercise will gradually increase causing the heart to bear faster. Aerobic respiration is the release of energy from glucose in the presence of Oxygen. Aerobic means in air, but it is the Oxygen in the air that is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. This has a major part of your pulse rate rising during exercise because your heart starts to pump more blood faster so that energy can be delivered to the working muscles as quickly as possible.

Method: -
