ABSTRACT


I measured work out times. The goal was to see if three ten minute work out or two fifteen minutes work outs or a solid thirty minute work out is better for you. I measured steps and heart rate, then averaged them to see the difference.

PROCEDURES

  1. Use the same exercise for all work outs (stationary bike)
  2. Measure rotations involved in each exercise set for a full minute every five minutes. Average the results
  3. Multiply the average by the number of minutes in the work out
  4. Measure heart rate half way through the work out and at the end of your work out then average them
  5. Repeat all work outs until the total time for each work out set is the same (Make sure to do each set at least three times, so three thirty minute work out, six fifteen minute work out, and nine ten minute work outs)
  6. Average the heart rate and steps to find the average for each work out set
  7. Graph results

FINDINGS

All three methods will give you the same amount of steps. However the heart rate stays the highest through the longer work out. With a significantly higher heart rate the thirty minute work out is the most effective work out. The fifteen minute work out eged out the ten minute work out the same way. It makes sense though, if you want a oven to cook efficiently you need it to stay on constantly, not turn it on for ten minutes then take a break or it will just have to heat up again. I wish I could have measured the calories, but the calculations were almost impossible and very inaccurate.
