This dataset, Stepping_df, is a data frame containing heart rate measurements of subjects performing stepping exercises at different heights and frequencies. Each subject's resting heart rate was measured before a trial (HRInit) and after stepping (HRFinal). Step heights include 5.75 inches (Low) and 11.5 inches (High), and stepping frequencies include 14 steps/min (Slow), 21 steps/min (Medium), and 28 steps/min (Fast), resulting in six possible height/frequency combinations. Each trial lasted three minutes, with subjects kept on pace by an electric metronome and heart rate counted by an experimenter.
Usage
data(Stepping_df)Format
A data frame with 30 observations and 6 variables:
- Order
Numeric vector indicating the order of the measurement.
- Block
Numeric vector indicating the block or session number.
- Height
Factor with 2 levels indicating step height (1 = Low, 2 = High).
- Freq
Factor with 3 levels indicating stepping frequency (1 = Slow, 2 = Medium, 3 = Fast).
- HRInit
Numeric vector indicating the subject's heart rate before the trial (beats per minute).
- HRFinal
Numeric vector indicating the subject's heart rate after the trial (beats per minute).
Details
