The Effects of Exercise on Recovery Time

The Effects of Exercise on Recovery Time

Aims

====

I am going to test how long it takes a persons heart rate to return to

their resting hear rate after different periods of exercise. I will

vary the time spent exercising each time and I will keep the intensity

of the exercise constant.

Preliminary Work

================

During my preliminary work I tested how my heart rate reacted to

different periods of exercise. I measured my resting heart rate at 77

bmp. Unfortunately the school does not own heart monitors so I had to

take my pulse manually so this may not be accurate. Firstly I did

step-ups for one minute at a set intensity, my heart rate was 117 bpm.

Then I did step-ups for two minutes and measured my hear rate, it was

126 bpm. When I did the same exercise and intensity for five minutes

my heart rate was 250 bpm. Because I thought that there was enough

difference between my bpms I decided to use minutes for my exercise

times. I will use one minute, two minutes, three minutes etc up to

five minutes. I used a stop clock to measure my bpm. I measured how

long it took my body to recover when I exercised for one minute and

when I exercised for five minutes. For five minutes of exercise it

took my bpm about three minutes to recover and when I exercised for

one minute it took my bpm about one minute. I think that these

recovery times are far enough apart to use minutes for my experiment.

Equipment

· Stop clock

· Heart monitor

· Stepping block

Fair test Factors

· I will take five repeats of the experiment and average the results

to get a better end result.

· I will use the same person throughout the experiment because some

people will recover faster than others, i.e. people that do a lot of

exercise regularly will have a faster recovery rate because their

heart and lungs will be fitter and healthier than a person who doesn't
