Name: Heart Rate and Stepping

 

Abstract:  An experiment was conducted by students at The Ohio State University in the fall of 1993 to explore the nature of the relationship between a person's heart rate and the frequency at which that person stepped up and down on steps of various heights.  Each subject performed the activity for three minutes.  Subjects were kept on pace by the beat of an electric metronome.  One experimenter counted the subject's pulse for 20 seconds before and after each trial.  The subject always rested between trials until her or his heart rate returned to close to the beginning rate.  Another experimenter kept track of the time spent stepping.  Each subject was always measured and timed by the same pair of experimenters to reduce variability in the experiment.  Each pair of experimenters was treated as a block.  There were thirty cases.

 

Variables (column):

  1. Order (the overall performance order of the trial)
  2. Block (the subject and experimenters' block number)
  3. Height (height of the step, 0=low 5.75", 1=high 11.5")
  4. Frequency (the rate of stepping, 1=slow 14 steps/min, 2=medium 21 steps/min, 3=high 28 steps/min)
  5. RestHR (the resting heart rate of the subject before a trial, in beats per minute)
  6. FinalHR (the final heart rate of the subject after a trial, in beats per minute)

Possible Uses:  Matched Pairs T Test, Independent Sample T Test, Regression, Correlation
