Repeat-sprint ability test
Almost every field and court sport is decided by repeat efforts, not by a single sprint. The RSA test measures the thing that actually runs out in the last quarter: your ability to keep producing the same sprint.
Repeat-sprint ability is scored as how many maximal sprints you complete before dropping more than 5% off your first effort — typically 6 × 30m on 30 seconds. The information is in reps four, five and six, not the first one.
Protocols vary enough between clubs that cross-comparison is rarely meaningful. Track your own drop-off across a pre-season.
The point of the test
Fatigue resistance in maximal sprinting. The output is not your fastest sprint — it is how many you can hold within 5% of it.
Why it is in the Train Smart battery: How long your speed lasts, which decides last quarters.
How to run it
6 × 30m sprints on 30s. Record how many you complete before you drop more than 5% off your first time.
- What you need
- 30m of flat surface · A stopwatch or gates · A partner to time and count
What is a good score?
We are not going to publish a precise-looking table for this test. Reported ranges vary too much with protocol, equipment, level, age and sex for a single table to be honest, and most of the tables in circulation for it are uncited copies of each other.
The comparison that actually changes your training is against your own last score. That is not a consolation prize — it is what the monitoring literature supports, and it is what Train Smart does: re-test every eight weeks under the same conditions and let the trend, not the percentile, drive the program. The papers behind that are here.
What people get wrong
Most of the variation between two tests is protocol, not fitness. These are the faults that make one score incomparable to the last.
- Focusing on the first rep.
- The first sprint is a speed test you have already done. The information here is in reps four, five and six.
- Pacing the set.
- Deliberately running the early reps at 90% to "last longer" produces a great drop-off percentage and a useless result. Every rep is maximal.
- Letting the recovery drift.
- 30 seconds means 30 seconds from the start of one rep to the start of the next. A recovery that stretches to 45 seconds turns it into a different test.
How to actually move the number
RSA has an aerobic engine underneath it — the recovery between sprints is aerobic work — and a speed ceiling above it. Both matter, and the limiter is usually the engine.
- Raise the ceiling: pure speed work, fresh, full recovery, low volume. A faster maximum means 95% of it is faster too.
- Raise the floor: aerobic base work. This is what clears the fatigue between reps and it is the half most athletes skip because it is boring.
- Train the specific quality: short maximal efforts on short, incomplete recovery — but sparingly. This session is very costly and does not need to be done weekly all year.
