Pulse rate During the practical while at rest the pulse is at a normal speed as the person is not doing any activity which requires lots of energy. This changes when the person starts to exercise as the line on the graph increases‚ this shows that the pulse rate is increasing because the heart is beating faster to make sure enough oxygen reaches the cells‚ this also causes the breathing to increase as the body has to take in more oxygen to supply the body and remove the carbon dioxide.

breathing rate will increase during exercise. It was hypothesised that if the amount of exercise (independent variable) increases‚ then the individual’s heart rate (bpm) and breathing rate (breaths-pm) (dependant variables) will increase when the environment in which the exercise is completed and a consistent and appropriate method of measurement for the dependant variables are kept constant. It was hypothesised that if physical exercise was increased‚ an individual’s heart and breathing rate would increase

A reaction is a chemical process in which substances decomposes‚ or combines with other substances. In this case it is synthesis chemical process which creates new products. However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration

the 1900’s‚ the overall death rate of the population in Britain has decreased. For males‚ the death rate has dropped from 25829 in 1901 to a mere 8477 in 2000.

Heart rate is an extremely important part of many people’s lives. It affects our personal health and how our body works. When the body exercises‚ the heart rate goes up and when the body is inactive or not being active the heart rate goes down. When the pulse is pumping fast‚ then that means work is being done. Having a high heart rate is good for the heart and the body. Obese people can use heart rate and exercise to change their life. Due to the amount of people that are obese‚ a good amount of
