30-15 Intermittent Fitness Test (30-15 IFT)

30-15 Intermittent Fitness Test (30-15 IFT) is an intermittent fitness test created by Martin Buchheit (2008), to more closely replicate the demands of intermittent sports compared to the standard beep test. Unlike in the beep test, where athletes run continuously with increasing speed every minute, this test involves 30 seconds of running alternated with 15 seconds of walking. There is a similar test, the Interval Shuttle Run Test (ISRT) with the same work/rest intervals but with different running speeds and over a 20m course. The Yo-Yo intermittent tests is another intermittent type beep test.

VO2max (ml.kg-1.min-1) = 28.3 – (2.15 x G) – (0.741 x A) – (0.0357 x W) + (0.0586 x A x VIFT) + (1.03 x VIFT)
