Conclusions of the activity about breathe/ heartrate and exercise:

During the exercise, the heart must beat faster to eliminate excess carbon dioxide and increase the supply of oxygen in the body. The signalling process stimulates the heart to beat faster during exercise, with inputs coming from many parts of the body.

I think that exercising does affect your pulse and will increase the amount of heartbeats because when you exercise your body has to pump more blood. This is because when you exercise, the cells that are in your muscles need more energy to move. Your muscles get this energy from respiration. This travels in the blood so if your muscles need more oxygen and glucose, they get it from the blood.

Also when you have did a lot of exercise you can feel your pulse rate in your neck beating really fast. I think that my pulse rate will take about 4, 5 or 6 minutes for it to return back to normality.

Make sure that all the experiments you do on measuring your pulse rate are fair (don’t eat before the experiment or do not do exercise).

1.    - First, The time in which you do the experiment should be kept the same.

2.    - Do the same type of exercise each time.

3.    - Wait until your pulse rate returns to normal before doing the exercise again.

4.    - Do you the experiment at the morning when you wake up. This is a whole lot easier than doing it in the afternoon because if you want to do this experiment twice you have to eat and rest the same amount which you did the day before.

Method:

During the morning wake up about 25 minutes earlier then you usually do and measure your pulse rate for one minute. Then do 10 jumping (1 for 6 sec.) in 1 min.  Repeat what you just did again the day after.

 See if your pulse rate is similar to the first test you did and if it is not, try the experiment again the day after because you have obviously not made it a fair test. I will repeat this experiment to make it more accurate.
