To calculate your predicted VO_2max from your 20 meter shuttle run test result, enter your level and number of shuttles for that level in the boxes below, and then click the "calculate" button. For a listing of the number of shuttles for each level, go here.

For example, if you scored 8-5 on the beep test, you would enter 8 in the first box, and 5 in the second.

But what does this mean?

• The above caluclator gives you a fitness rating based on your VO_2max score, from these tables: VO_2max norms for different ages.
• You can also compare it to the table of Beep Test Norms — ratings for beep test scores for all ages.

Calculations

• The above calculator was developed by Topend Sports from the published tables in Ramsbottom et al. (1988) "A progressive shuttle run test to estimate maximal oxygen uptake." British Journal of Sports Medicine 22: 141-5. The calculator appears to be accurate to within 0.1 ml/kg/min of the published values.
• There is another calculation to determine VO_2max using the following equation by Ahmaidi et al. (1992), where velocity is determined using the distance covered in 30 seconds during the last stage of the test.

VO_2max = 31.025 + (3.238 × velocity) - (3.248 × age ) + (0.1536 × age × velocity)

• There is another published calculation to determine VO_2max from the beep test, using the following equation by St Clair Gibson et al. (1998), where vel equals the maximum speed achieved.

  predicted VO_2max  = (6.0 × vel) - 24.4

Reference: St Clair Gibson A, Broomhead S, Lambert MI and Hawley JA (1998) Prediction of maximal oxygen uptake from a 20 m shuttle run as measured directly in runners and squash players. Journal of Sports Sciences 16:331-335.

• The prediction equation from Flouris et al. (2005) where vel equals the maximal attained speed.

  VO_2max = (vel × 6.65 - 35.8) × 0.95 + 0.182
