what did it do? This experiment showed how long it takes your heart rate to go back to normal after you exercise.


We set the experiment up this way because we thought it was the best way to compare.


Hypothesis: Doing jumping jacks for one minute will increase the heart rate more than push ups for one minute.


Independent variable: work out


Dependent variable: heart rate


Control: heart rate standing


Constant: time work out (s) and person




step 1

first, the heart rate was recorded for 30 seconds 3 times before exercising (standing)

step 2

jumping jacks were done for one minute and then the heart rate was taken, this was done three times to find an accurate solution of how jumping jacks effects the heart rate.

Step 3

next, push ups were done and then took the heart rate was taken, this was done three times to find an accurate solution of how push ups effects the heart rate.

step 4

finally the average was recorded of each exercise by taking the three trials and adding them up and diving by three. This shows a more accurate number for the heart rate.

conclusion

Jumping jacks will increase your heart rate more than push ups for one minute. This was true because the average of jumping jacks was higher than the average of push ups. Average of jumping jacks for MK: 103, Average of push ups for Chris: 110.6

Average of push ups for MK: 83, Average of push ups for Chris: 75.3

The treason the jumping jacks made a higher heart rate was because it took more energy from the body as to push ups that didn't require as much muscle movement or energy.
