The Fourth Quarter Belongs To The Player Who Can Still Breathe
Basketball is a game of repeated bursts. Sprint back in transition, close out, box out, cut, then do it again 20 seconds later.
Simon Kerle spent 18 years as a professional basketballer in the NBL and Europe and captained the Brisbane Bullets in 2001. He knows the moment your legs go: late in the fourth, defending a big who still has gas.
Breath hold sprint training is built for that moment. Control your breath. Control the result.
Why Breathing Limits Repeat Efforts
Breathing is not free. In a laboratory study during maximal exercise, Harms and colleagues (1997) showed that the work of the breathing muscles can compromise blood flow to the working legs.
Think of a guard picking up full court after back to back transition possessions. It is a useful reminder that breathing and leg fatigue are linked when intensity is at its highest.
To be clear, that study did not test breath hold training. It explains why breathing matters at high intensity. It does not show that breath holds fix it.
What The Basketball Study Found
Unlike most sports, basketball has a direct study. Lapointe and colleagues (2020) worked with 17 national level basketball players, men and women.
Over four weeks, both groups added eight sessions of repeated sprint training, mixing straight line and change of direction sprints. One group used voluntary hypoventilation at low lung volume, known as VHL: breathe out normally, hold at the bottom of the exhale, then perform the effort. The other breathed normally.
Players were tested on 12 sprints of 30 metres with 25 seconds of rest between them.
Best sprint time did not clearly change. This method did not make anyone faster over a single sprint.
Sprint decrement fell sharply. The drop off across the 12 sprints reduced by 24.5% in the VHL group, compared with 5.9% in the normal breathing group. Put simply, the VHL players held their speed much better from first sprint to last.
The researchers also measured faster muscle reoxygenation during the recovery periods and changes in muscle activation and blood potassium that fit with reduced fatigue.
One more honest detail. Both groups improved on the 30 15 Intermittent Fitness Test by a similar amount, 6.9% and 7.5%. The extra benefit of VHL showed up in repeated sprints, not in that broader fitness test.
It is one study with 17 players. It is promising, and it needs replication.
Supporting Evidence From Other Team Sports
Woorons and colleagues (2020) trained 20 team sport athletes on a bike, six sessions of short hard efforts over three weeks. Only the VHL group improved Yo Yo Intermittent Recovery Level 1 distance, from 1,111 to 1,468 metres, and its fatigue index in a repeated sprint test fell.
For a basketball program, that opens a low impact option. Bigs with sore knees or players in a heavy game week can get the stimulus without more court pounding.
A 2025 meta analysis by Précart and colleagues, which included the basketball study, found the benefits of VHL repeated sprint training sit mainly in fatigue resistance and repeated sprint ability. Not top speed. Not VO2max.
What This Will Not Do
The research does not show higher top speed or a higher VO2max. Anyone selling breath holds as a speed or aerobic capacity fix is overselling it.
It is also not a replacement for conditioning. In every study above, the breath hold group and the comparison group did the same sprint work. Only the breathing changed. The sprints still have to be run.
Composure At The Line: What We Can And Cannot Say
Slow breathing is a separate method from breath hold training, so we keep the evidence separate too.
A 2022 meta analysis by Laborde and colleagues found voluntary slow breathing increases vagally mediated heart rate variability, a marker linked to the calming branch of the nervous system.
Many players use a slow nasal breath to settle before a free throw. That is reasonable. But no study we found has shown slow breathing improves free throw percentage, so we will not claim it does.
How We Program It For A Basketball Team
Nasal breathing in warm ups and shootarounds. Light, slow nasal breathing builds the base and gets players used to working with less air.
Breath holds after a normal exhale. Short static holds at low lung volume. Full recovery, no straining. Players learn how their body responds before adding sprints.
VHL court sprints. Two sessions a week for four weeks, as in the basketball study. Exhale, hold, sprint baseline to baseline or through a change of direction pattern, breathe on recovery.
Bike option. Short hard efforts on the bike with VHL when court load needs to come down.
Coaching Cues That Work
Exhale, do not empty. Breathe out a normal, relaxed breath. Forcing all the air out is not the target and makes the hold harder to control.
Hold, then go. Start the effort straight after the exhale and keep it short. The hold ends when the effort ends, or earlier.
Recover through the nose where possible. Take the first breath calmly, then settle back into light nasal breathing before the next rep.
Quality over volume. If technique falls apart on the court, the set is over. This is a fatigue resistance drill, not a test of willpower.
Expect discomfort, not distress. Strong air hunger is normal. Dizziness, tingling or confusion are not. Stop immediately.
Test it. Run a 12 x 30 metre repeated sprint test before and after the block and track the decrement, not just the fastest time.
Safety: never do breath holds in or near water, never while driving and never alone. Stop if you feel dizzy. Get medical clearance first if you are pregnant or have a heart, lung or blood pressure condition.
This is not wellness. This is your competitive edge.
FOR ELITE ATHLETES, THIS CAN HELP YOU
✔ Hold your sprint speed across repeated efforts, with less drop off
✔ Recover between bursts with faster muscle reoxygenation
✔ Train repeated sprint ability on a bike when court load needs managing
✔ Build a slow breathing routine that shifts heart rate variability toward calm
Performance takeawayThis will not add a step to your first sprint. The evidence says it helps you keep that step on the tenth.
In a close game, the team that holds its speed late wins the possessions that matter.
