How It Works

Beep Test to VO2max Conversion

The multi-stage fitness test (beep test) involves running 20-meter shuttles at progressively faster speeds. The level reached correlates strongly with maximal oxygen uptake.

Ramsbottom Equation

VO2max = 3.46 x Level (decimal) + 12.2 mL/kg/min

The decimal level combines the level number with shuttles (e.g., Level 9 shuttle 6 = 9.6). This equation provides a reasonable estimate for adult populations.

Worked Example

An athlete reaches Level 9, shuttle 6 on the beep test.

level = 9shuttles = 6
  1. 01Decimal level = 9 + 6/10 = 9.6
  2. 02VO2max = 3.46 x 9.6 + 12.2 = 33.216 + 12.2 = 45.4 mL/kg/min

Frequently Asked Questions

What is a good beep test level?

Average adult: Level 6-7. Good fitness: Level 8-10. Very fit: Level 11-13. Elite athletes: Level 13+. Some professional soccer players reach Level 15+.

How does the beep test work?

You run 20 meters back and forth (shuttles) in time with audio beeps. The beeps get faster each level. You stop when you can no longer reach the line before the beep twice in a row.

Is the beep test accurate for VO2max?

It correlates at r = 0.80-0.92 with laboratory VO2max tests. Motivation and running economy affect results, so it is an estimate rather than a precise measurement.
