Where does your squad stand?

Compare any cohort against real 30-15 IFT data. Pick the test version, filter by sport, level, age and position, and see the percentiles your athletes need to beat.

The 30-15 IFT has been downloaded by over 100,000 users worldwide. This database holds 3,000+ results, combining individual records and cohorts reconstructed from published aggregate statistics. Help us grow it →

Step 1 — Choose your test version

Results from different versions cannot be compared. Pick the one your squad performed.

Shuttle

40 m or 28 m shuttle. Football, handball, basketball, hockey, netball, racquet — most team and court sports.

Ice hockey

On-ice adaptation.

Straight 400 m

Track, no change of direction. Runners.

Note on pooling: The 40 m and 28 m shuttle versions are combined here. Haydar et al. (2011) showed that shuttle length, change of direction, and starting speed (8 or 10 km/h) do not meaningfully affect VIFT results. See Haydar et al., 2011.

Help build the benchmarks

The 30-15 IFT has been downloaded by over 100,000 users worldwide, but most of that data never leaves the building. If everyone shared even a small amount, the public benchmarks would be the best in sport science.

One form covers everything: share your test data, ask a question, report a bug, or just tell us how you use the test. Takes 2 minutes.

About the 30-15 IFT and these benchmarks

What is the 30-15 IFT?

The 30-15 Intermittent Fitness Test is a shuttle run protocol developed by Martin Buchheit in 2001 to assess maximal aerobic speed in team and court sports. The test alternates 30-second shuttle runs at progressive speeds with 15-second passive recoveries. The final running velocity reached, called VIFT, is used to design individualised high-intensity interval training, prescribe small-sided games intensity, and evaluate aerobic fitness in sports that involve repeated changes of direction.

What does this database show?

This open-access tool lets coaches and sport scientists compare their athletes against real 30-15 IFT results from clubs, federations and academies around the world. Filter by sport, competition level, age category, sex and playing position to find the cohort that matches your athletes, then see how their VIFT scores rank within it.

Where does the data come from?

Two sources. Most rows are individual test results shared by coaches and contributors over many years. A smaller portion are cohorts reconstructed from published aggregate statistics in Science and Application of High-Intensity Interval Training (Laursen and Buchheit, Human Kinetics 2018). Reconstructed rows are clearly labelled when they appear in a filtered cohort. The 40 m and 28 m shuttle versions are pooled because Haydar et al. (2011) showed they produce equivalent results.

Who is this for?

Coaches, strength and conditioning practitioners, sport scientists, physical educators, and researchers who use the 30-15 IFT and need to put individual results into context. The dataset is free to use and grows whenever contributors share their data.
