# How Much of an Affect Does Exercise Have On Our Pulse Rate?

Extracts from this document...

Introduction

Biology investigation: How much of an affect does exercise have on our Pulse rate? Aim: To find out if exercise affects pulse rate. Prediction: I think that as I increase the amount of exercise, my pulse rate will also increase, until my heart reaches its optimum amount of beats and cannot increase anymore. My pulse rate will still remain high but it will level out. Explanation of prediction: As the amount of exercise I do increases, my muscles will require more energy, therefore my body will have to respire at a faster rate than normal to keep up the demand. Respiration is oxidation of glucose and oxygen to release energy. ...read more.

The increase in heart rate enables the carbon dioxide to be transported by your blood to the lungs where it is breathed out. The water which is created during the process is sent to the perspirary glands where it is excreted in the for of perspire or sweat. Fair testing: For this experiment to be fair we need to: * Use the same person for all of the exercises. * Do all the exercises on the same day so that the temperature of the room is exactly the same, and the person's diet is the same. * Use the same type of exercise e.g. ...read more.

Conclusion

2.) I will then do step-ups on a PE bench for 1 minute, then immediately after, take my pulse rate. (BPM) 3.) I will then rest until my pulse rate has recovered. I will then repeat step 1 to find my average 'pulse rate at rest'. 4.) I will then repeat step 2, but this time I will exercise for 2 min. 5.) I will repeat this procedure of exercising, recording my pulse rate, then resting. I will exercise for periods of time of: 1 min, 2 min, 3 min, 4 min, 5 min and 6 min, recording my pulse rate before and after exercise. I will use a stop clock for accurate timing, and I will wear training shoes to prevent accidents while exercising. ...read more.

plasma in the blood which carries glucose and the red blood cells which carry oxygen around the body as oxyhaemoglobin), so it will complete more bpm. However, the body cannot keep doing this for ever so I think that at some point your body's oxygen supply will reach the oxygen demand.

connective tissue and in part because of the contraction of muscles in the arterial walls. This return to normal is imporatnt in maintaining a continuous flow of blood through the capillaries during the period while the heart is at rest.

1. ## How does Exercise affect the pulse rate

The heart fills up fuller, when it relaxes. This stretches the heart like elastic so it contracts more strongly and pumps out more blood at each beat. The contracting muscles squeeze on the veins squirting the blood faster back to the heart. The blood carries the glucose and sugar which the muscles need to carry out their work.

2. ## How exercise affects the pulse rate

Rapid movement of limbs stimulates receptors in the skeletal muscles and tendons. These transmit impulses to the heart, leading to a further increase in the heart rate. The overall equation for respiration is: C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP Glucose + oxygen = carbon dioxide + water + energy (adenosine triphosphate)

If the pulse rate is higher that means your heart is pumping very fast to get all energy and oxygen to its place. Here is a picture from which I have found on Encarta below- Blood Blood is a fluid that acts as a conveyor belt, which carries oxygen to all living cells in your body.

So the lactic acid has to be replaced and repaid with oxygen, this is known as the o2 debt. The oxygen is carried around in our red blood cells. The blood is pumped all around our body constantly. The haemoglobins in the red blood cells is what carries the oxygen in the blood.
