Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Float
  • Units: seconds (s); percent (%) for Change
  • Column Name: rise_time, mean_rise_time, rise_time_change
  • Optimal Direction: Lower is better
  • Measurement: Time from Seat Off to Stand of the same repetition

Variants

  • Rise Time (rise_time) (per repetition): time from Seat Off to Stand.
  • Mean Rise Time (mean_rise_time) (summary): average Rise Time across all analyzed repetitions.
  • Rise Time Change (rise_time_change) (summary): percent change from the first to the last valid repetition, 100 × (last − first) / first. Positive values mean the rise got slower. Requires at least two valid repetitions.

Description

Rise Time is the duration of the standing-up portion of each repetition. A shorter Rise Time reflects a faster, more powerful rise. Rise Time Change compares only valid repetitions, so a final partial stand does not distort the trend.

Use Cases

  • Speed of the rise, separate from the descent
  • Fatigue across repetitions
  • Comparison with Descent Time to assess movement control
