Popular sporting activities such as tennis and many team sports require the athlete to repeatedly perform bouts of near-maximum to maximum efforts, interspersed with periods of recovery. These intense efforts are generally referred to as “sprints” and typically last <10 seconds. Recovery periods are usually brief, lasting <60 seconds. The ability to repeatedly sprint with little recovery is a component of fitness that requires it’s own definition, assessment procedures, and training strategy.
Sprinting Terms
- Sprint exercise that lasts < 10 seconds with recovery periods < 60 seconds is referred to as repeated sprint exercise.1
- The ability to perform RSE is termed repeated sprint ability (RSA) and is an important fitness quality in many team and racket sports.1,2,3,4 As the number of repeated sprints increases, the athlete will fatigue, which results in a decline in sprint speed. A greater loss in sprint speed will result in decreased performance. This reduction in sprint speed is common toward the end of sporting matches.1
- Intermittent sprint exercise is different from RSE as it allows for full to near-full recovery between bouts of sprinting <10 seconds.1 Near to full recovery may take 60-300 seconds.
Relation to Other Fitness Qualities *
From a fitness perspective RSA seems to have a closer relationship with qualities of short sprinting than maximum aerobic capacity (VO₂ Max). In a population of well trained Australian Rules football players, the strongest predictor of RSA was found to be the fastest individual 30-meter sprint time.5
Maximum aerobic capacity plays a role in RSA but it does not seem to be strongly correlated.9 There seems to be a stronger relationship between other markers of aerobic fitness such as velocity at lactate threshold (vLT) and, to a lesser extent, velocity at VO₂ Max (vVO₂ Max).6 This is important to know in order to help structure training.

Testing
There are a number of ways to test RSA. Established tests for certain sports such as soccer (e.g. the Bangsbo Soccer Sprint Test) exist, but testing can be customized as the athlete/coach sees fit.
Repeated Sprint Ability Test
- Warm-up for 10 minutes performing low-intensity running dynamic and static stretches as well as 30-meter acceleration efforts. Ensure the warm-up is the same each time the athlete is tested.
- Perform 6 x 30 m repeated sprints
- Rest/walk for 20 seconds between sprints
- Each sprint is to be timed
This is a sample test procedure. Factors such as distance of sprints and rest intervals can be manipulated.
Sprint Decrement Calculation
The following calculation provides the athlete with data on how sprint speed decreases over subsequent sprinting efforts. It provides the athlete with a measure of their RSA. This can be used as a test-retest tool to determine the effectiveness of training or used to compare with other athletes.
Sprint Decrement Score (%) = {(Sprint 1 + Sprint 2 + . . . +Sprint 6) / (Best Sprint X 6) – 1}
Training
What types of training may be valuable to the athlete who wishes to improve repeat sprint ability?
Repeat Sprint Exercise- Actually performing repeat sprint exercise or interval training may help develop RSA. An example would be:
- 3 sets of 4-second sprints, with 20 seconds of recovery between sprints. Recovery between sets would be 4.5 minutes.
Sprint Training- Improving single best sprint performance may help improve RSA. This is based on the notion that faster short sprint speed performance seems to be associated with better RSA.7
Lactate Threshold Training- Training at or above the lactate threshold may be beneficial as there is a relationship between vLT and RSA. For the athlete involved in team sports, small-sided games may help as this often requires the athlete to perform at or above the lactate threshold.
Strength Training- Strength training seems to be beneficial for improving RSA particularly when shorter rest periods are utilized (e.g. 20 seconds as opposed to 80 seconds).10
Bottom Line
Repeated sprint ability is an important component of many racquet and team sports. Although there is not abundant evidence on the best ways to train RSA, it can be assessed and improved.
