Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Float
  • Units: seconds (s)
  • Column Name: total_time (Total Time), time_to_final_stand (Time to Final Stand)
  • Optimal Direction: Lower is better
  • Measurement: Time from the first repetition’s Seat Off to the last analyzed repetition’s Sit (Total Time) or Stand (Time to Final Stand)

Variants

  • Total Time: first Seat Off to the last repetition’s Sit.
  • Time to Final Stand: first Seat Off to the last repetition’s Stand.

Description

Total Time is the overall time to complete the test. Unlike Repetition Time, it includes any time spent seated between repetitions. Timing starts at the first Seat Off, when the person leaves the chair, rather than at a start command. Sit-to-stand protocols differ on whether timing stops when the person reaches the final stand or when they sit back down. Time to Final Stand and Total Time cover both conventions. Total Time is part of QA: captures where Total Time is less than 0.6 seconds or more than 12 seconds per analyzed repetition fail QA.

Use Cases

  • Primary score for timed tests such as the 5xSTS
  • Comparison across sessions or against published reference values that use the same timing convention
