The Last Sprint Is The One That Counts
Every coach has seen it. The game is tight, the clock is running down, and one team still has legs while the other is a step late to everything.
That gap is not luck. It is repeated sprint ability, and it is one of the most trainable qualities in team sport.
This is not about who is fastest on a fresh set of legs. It is about who can produce close to their best effort again and again, with almost no rest, deep into the fourth quarter.
What Repeated Sprint Ability Actually Is
Repeated sprint ability is the capacity to recover and reproduce sprint performance across a series of efforts.
Girard, Mendez Villanueva and Bishop (2011) reviewed the research and noted that sprints of under 10 seconds separated by recoveries of under 60 seconds are common in team and racket sports. That is the pattern of basketball, rugby league, AFL, netball and football.
In running, fatigue shows up as slower maximal or mean sprint speed across the set. In cycling tests, it shows up as falling peak power or total work.
Their review identified the main limiters inside the muscle: the supply of energy from phosphocreatine, anaerobic glycolysis and oxidative metabolism, plus the build up of metabolic by products such as hydrogen ions. Neural factors, including incomplete muscle activation, also play a role.
Why It Decides Games
The physical drop off late in matches is well documented.
Mohr, Krustrup and Bangsbo (2003) tracked high standard soccer players and found high intensity running was 35 to 45% lower in the last 15 minutes than in the first 15 minutes, regardless of playing position or competitive level.
They also found that after the most intense five minute period of a match, performance in the next five minutes fell 12% below the game average. Fatigue is not just an end of game problem. It hits straight after the hardest passages of play.
So does a lab test of repeated sprints tell you anything about the game? Rampinini and colleagues (2007) tested 18 top level professional soccer players and compared their results with match tracking data.
Mean time on a repeated sprint test was significantly related to very high intensity running and sprint distance in matches. Players who held their speed across the test covered more of the work that matters on game day.
That is the case for training it directly. The team that holds its sprint quality longest gets to the loose ball, makes the cover tackle and finishes the fast break.
Training It With Breath Holds
One method with growing evidence in team sport is repeated sprint training with voluntary hypoventilation at low lung volume, known as VHL.
The athlete exhales normally, holds the breath at the bottom of that exhale, and sprints. Holding at low lung volume drops blood oxygen during the effort, which adds a hypoxic stress to normal sprint training at sea level.
Fornasier Santos, Millet and Woorons (2018) ran this with 21 highly trained rugby players. Over four weeks, the VHL group did seven sessions of repeated 40 metre sprints.
In a repeated sprint test to exhaustion, the VHL group went from 9.1 to 14.9 sprints before task failure, an increase of 64%. The group doing the same sprints with normal breathing showed no significant change, moving from 9.8 to 10.4.
Basketball shows a similar pattern. Lapointe and colleagues (2020) gave 17 basketball players eight repeated sprint sessions over four weeks, with or without VHL.
The VHL group improved their sprint decrement by about 24.5%, compared with about 5.9% in the control group. Their fastest single sprint did not clearly change.
What The Evidence Does Not Say
Sports scientists will rightly ask about the limits, so here they are.
These are small studies, with 21 and 17 athletes. They measured repeated sprint outcomes over four weeks, not match results across a season.
The benefit shows up as fatigue resistance: more sprints before failure and a smaller drop off from sprint to sprint. In the basketball study, top speed did not clearly improve. Breath hold sprint training is a tool for holding speed, not for raising it.
That distinction matters for programming. VHL sits alongside your speed, strength and conditioning work. It does not replace it.
How We Apply It
In Vincere Protocol, VHL sprints are introduced progressively, after athletes have learned to hold calmly after a normal exhale while at rest and at low intensity.
Sessions are short, sprint distances match the sport, and recovery is controlled through the nose. The aim is quality under fatigue, not suffering for its own sake.
For a basketball squad, that might mean court length efforts with defensive slides built in. For rugby league or AFL, longer efforts that mirror the distances players actually cover in a passage of play.
We place these sessions where they will not compromise speed work. Maximal speed and acceleration training needs fresh legs and full recovery. Breath hold sprint work targets a different quality, so it sits later in the week or later in the session.
Coaches should also track the right numbers. A stopwatch on the first sprint tells you little. Track the drop off across the set, the number of quality efforts before times fall away, and how quickly heart rate and breathing settle between reps.
Questions Coaches Should Ask
Before adding any repeated sprint method, ask three questions.
First, what does the drop off look like for this athlete now? Test it before you train it, so you have a baseline that means something.
Second, where does this fit in the weekly load? Repeated sprint work is demanding. It has to be programmed around games, contact sessions and recovery, not stacked on top of them.
Third, is the athlete ready for breath hold work? Athletes who cannot yet hold calmly after a normal exhale at rest are not ready to do it at sprint intensity. Build the base first.
Safety: breath hold training is done on land only. Never in or near water, never while driving, never alone. Stop if you feel dizzy. Seek medical clearance first if you are pregnant or have a heart, lung or blood pressure condition.
FOR ELITE ATHLETES, THIS CAN HELP YOU
✔ Understand why late game sprint quality falls and what drives it
✔ Train fatigue resistance across repeated sprints, as shown in rugby and basketball studies
✔ Complete more sprints before task failure, as seen in highly trained rugby players
✔ Reduce sprint decrement across a repeated sprint set
✔ Add a hypoxic stress to sprint sessions without leaving sea level
Performance takeawayGames are won by the athletes who can still sprint when everyone else is fading.
