The Game Is Won in the Gaps
Team sport is a string of repeated efforts. A sprint, a contest, a few seconds to reset, then go again.
Most athletes spend those seconds bent over, mouth open, gasping. What you do with your breath in that window shapes how ready you are for the next effort.
Here is what the research shows about recovering between efforts, including the parts that do not work as well as the internet claims.
Posture First: Hands on Knees Beats Hands on Head
Coaches have told athletes for years to stand tall with hands on head to open the chest. The data says otherwise.
Michaelson and colleagues (2019) tested 20 female varsity soccer players running four 4 minute efforts at 90 to 95% of maximum heart rate, with 3 minutes of passive recovery between each.
In the first 60 seconds of recovery, heart rate dropped by 53 beats per minute with hands on knees, compared with 31 beats per minute with hands on head. Tidal volume, the size of each breath, was also greater with hands on knees.
These were trained athletes doing genuinely hard intervals, which makes the result directly relevant to team sport conditioning.
The authors suggested that leaning forward on the knees may be more beneficial than the commonly taught upright posture as an immediate recovery position.
Simple, free and backed by data. Hands on knees, then get the breathing under control.
Slow Breathing Beats Box Breathing Straight After Hard Work
Kasap and Aydin (2025) compared three recovery breathing strategies after high intensity interval sessions on a spin bike in 40 physically active sports science students.
The options were normal spontaneous breathing, box breathing with four second inhale, hold, exhale and hold, and slow breathing at six breaths per minute with five seconds in and five seconds out.
Heart rate after the session was lowest with six breaths per minute, 154.8 beats per minute, compared with 164.7 with box breathing and 159.1 with spontaneous breathing. Perceived exertion was highest with box breathing.
Time for heart rate to return to baseline was not significantly different between the three methods. This was also a single session study in young, healthy students, so it shows acute effects only.
The practical message: straight after a maximal effort, do not force breath holds into the recovery. Slow, controlled breathing with a full exhale is the better choice, and box breathing added stress in this study.
Where Slow Breathing Did Not Help
This is the study most breathing coaches will not mention.
Raidl and colleagues (2026) put 34 participants through four weeks of supervised sprint interval training. Participants were randomised to a control group or an intervention group that added slow paced breathing after every session and every evening before bed.
Both groups improved. Sprint training reduced maximal power decrement and increased total work. But the slow breathing group gained nothing extra in performance, and their night time heart rate was slightly higher, by about 3 beats per minute.
The authors concluded that 10 minute slow breathing sessions after training offered limited value for performance or recovery.
We think that finding deserves respect. Slow breathing reliably raises vagally mediated heart rate variability during and after a session, as Laborde and colleagues (2022) showed across 223 studies. But a better HRV reading in the moment is not the same as better adaptation to training.
Building Recovery Capacity Into Training
Breathing in the gaps helps you reset. The bigger lever is training your body to tolerate repeated efforts in the first place.
That is where breath hold sprint training, voluntary hypoventilation at low lung volume, has the most relevant evidence.
Lapointe and colleagues (2020) had basketball players do eight repeated sprint sessions over four weeks, either with breath holds at low lung volume or with normal breathing. The breath hold group reduced their sprint decrement, the drop off across repeated sprints. It fell by 24.5% in the nine players training with breath holds, compared with 5.9% in the eight players breathing normally. Their fastest single sprint did not clearly change.
That is the pattern across this research. Breath hold sprint training improves fatigue resistance across repeated efforts, not top speed.
Safety: never practise breath holds in or near water, never while driving, stop if you feel dizzy, never train holds alone, and get medical clearance first if you are pregnant or have a heart, lung or blood pressure condition.
What This Means for Coaches
Put the pieces together and a clear picture forms. Posture and slow breathing help you reset in the moment. Breath holds forced straight after a maximal effort did not help in the research we found, and box breathing increased perceived exertion.
Slow breathing tacked onto the end of a session did not improve how athletes adapted to sprint training. So do not sell it to your playing group as a recovery shortcut.
The capacity to back up effort after effort is built in the training itself, and breath hold sprint training is one of the few breathing methods with controlled trials showing that in team sport athletes.
The Between Effort Protocol
Hands on knees. Lean forward, hands on knees, as soon as the effort ends.
Long exhale. Let the out breath run longer than the in breath. No forced holds straight after maximal work.
Slow it down. Move towards around six breaths per minute as heart rate allows.
Back to the nose. Return to nasal breathing as early as possible. It is a visible sign you are regaining control.
Train the capacity separately. Use breath hold sprint sessions in the program to build repeated sprint ability, not as a recovery tool.
FOR ELITE ATHLETES, THIS CAN HELP YOU
✔ Drop heart rate faster in the first minute of recovery with a hands on knees posture
✔ Recover with slow, six breaths per minute breathing instead of box breathing after maximal work
✔ Build fatigue resistance across repeated sprints with breath hold sprint training
✔ Save time by not relying on post session slow breathing to improve training adaptation
Performance takeawayRecovery between efforts is a skill. Posture and a slow exhale win the first minute.
Fatigue resistance is built in training, not found in the gaps.
