20 Meter Shuttle Run

Last Updated

Purpose

The 20 Meter Shuttle Run is a fitness test to estimate VO2max

Acronym 20 m SRT

Assessment Type

Performance Measure

Cost

Free

Actual Cost

$0.00

Key Descriptions

  • Participants repeatedly run a 20-meter distance at increasing speeds until they can no longer keep pace. A number of equations are available to predict VO2max from assessment performance.
    Administration instructions: (Léger et al., 1998)
    ? Distance of 20 meters is marked
    ? Subjects will complete the following sequence of runs in stages
    1. The participant will run the 20m, beginning with an audible beep
    2. The audible beep begins at a rate of 8.5km/h
    3. The audible beep is incrementally increased by 0.5km/h every 1 minute
  • The test continues until failure or fatigue occurs on 2 consecutive runs
    Note that variations and modifications to the test exist such as the Yo-Yo Intermittent Recovery Test, PACER test, and the 15m Test

Number of Items

1

Equipment Required

  • Marked distance of 20 meters on a flat, non-slip surface
  • An audio source able to produce an audible beep at an initial rate of 8.5km/h and able to increase 0.5 km/h every minute (● Various resources for audio include online video and audio files and smartphone applications)

Time to Administer

8-12 minutes

Required Training

No Training

Considerations

  • Numerous individuals can be tested concurrently in the same testing session
  • There are several modifications and variations to the test that are population specific such as Yo-Yo Intermittent Recovery Tests for athletes (Bangsbo et al, 2008)
  • Other methods exist to calculate VO2max values such maximal effort treadmill assessments (Aziz et al, 2005; Stickland et al, 2003)
  • This test fills a need for a feasible VO2max test that can be completed in a non-laboratory environment (Stickland et al, 2003)
  • Participant motivation and environmental factors such as ambient temperature, relative humidity and elevation can influence performance (Kim et al, 2011)

Non-Specific Patient Population

back to Populations

Standard Error of Measurement (SEM)

Healthy adults (calculated from Kim et al, 2011; n=119)

  • SEM for males (n=90): 2.0 shuttles
  • SEM for females (n=29): 0.6 shuttles
  • SEM for males and females (n = 119): 1.4 shuttles

Athletes (Aziz et al, 2005; n=12 professional male soccer players; mean age=27.2)

  • SEM: 2.3 shuttles

Military personnel (Calculated from statistics in Aandstad et al, 2011; Home Guard: n= 38; mean age = 38 years)

  • SEM: 1.0 shuttles
  • SEM: 0.1 last half laps completed

Minimal Detectable Change (MDC)

Healthy adults (Kim et al, 2011; n=119)

  • MDC95 for males (n=90): 5.5 shuttles
  • MDC95 for females (n=29): 1.7 shuttles
  • MDC95 for males and females (n = 119): 3.9 shuttles

Athletes (Calculated from statistics in Aziz et al, 2005)

  • MDC95 for entire group (n=12): 6.7 shuttles

Military personnel (Calculated from statistics in Aandstad et al, 2011)

  • MDC95 for entire group (n=38): 2.86 shuttles
  • MDC95 for entire group (n=38): 0.35 last half laps completed

Test/Retest Reliability

Healthy adults

  • Excellent test-retest reliability among males in shuttle counts (r = 0.87) (Kim et al, 2011)
  • Excellent test-retest reliability among females in shuttle counts (r = 0.97) (Kim et al, 2011)
  • Excellent test-retest reliability among males and females in shuttle counts (r = 0.93) (Kim et al, 2011)
  • Excellent test-retest reliability for completed stages (r = 0.95) (Léger et al, 1988; n = 81, age 20-45 years)

Athletes (Aziz et al, 2005)

  • Excellent test-retest reliability in shuttle counts (ICC = 0.97)

Healthy children (Léger et al, 1998; n = 139, age 6-16 years)

  • Excellent test-retest reliability for completed stages  (r = 0.89)

Military personnel (Aandstad et al, 2011)

  • Excellent test-retest reliability in shuttle counts (ICC = 0.96)
  • Excellent test-retest reliability in half laps completed (ICC = 0.95)

Criterion Validity (Predictive/Concurrent)

Concurrent validity:

Healthy males (Stickland et al, 2003)

  • Excellent concurrent validity compared with treadmill V02max in males (r = 0.88)

Healthy females (Stickland et al, 2003)

  • Excellent concurrent validity compared with treadmill V02max in females (r = 0.81

 

Predictive validity:

Healthy adults

  • Excellent predictive VO2max (r = 0.90) with input of speed [km/hr] (Léger et al, 1988; n = 77 men and women 18-50 years old)

Healthy children (Léger et al, 1988; n=188, boys and girls 8-19 years old)

  • Excellent predictive VO2max (r = 0.71) with inputs of speed [km/h] and age [years]

Military personnel (Aandstad et al, 2011)

  • Excellent predictive value for VO2max (ICC = 0.62) using input of last half level completed
    • r=0.80-0.82
