Investigating the effect of exercise on the heart rate and recovery time. There are different factors that affect the heart rate, they are the variables.... I have decided to go for distance run for our variable. I decided that the variables such as fitness and individual involved would be too hard to measure fairly. METHOD As I decided to use distance run as my variable and I am going to use Mark as my 'Guinea Pig', so I am going to make Mark run 20 meters, 40 meters, 60 meters, 80 meters and 100 meters. I am going to change the distance run 5 times. I am going to record his resting heart rate, his heart rate straight after exercise and time how long it takes for him to recover. To make sure that my results are reliable and correct. I am going to take the average of these two sets of results...
