Neck Training for Military Aviation
The population that produced nearly all the good evidence, because it had the most extreme problem.
Aircrew report neck pain at rates between roughly 19% and 83% a year, which is why air forces funded the most rigorous neck training research in existence. The demand is sustained load with added helmet mass under G, and the trainable outcome that matters operationally is not maximum strength but the proportion of available capacity that holding the head up consumes. Every published protocol uses three sessions a week.
The scale of the problem
| Population | One-year prevalence of neck pain |
|---|---|
| Fighter / high-performance pilots | 18.9% – 83% |
| Helicopter pilots | 43% – 67.3% |
| Helicopter crew | 28% – 45.3% |
| Main battle tank crews | 36.4% |
| Military office personnel | 65% |

Both ends of the fighter pilot range are real studies — 83% among 58 Danish F-16 pilots, 18.9% among 90 Belgian F-16 pilots. The spread reflects airframe, mission profile, and how the question was asked.
Operational readiness depends on aircrew being able to turn their heads. That is why this research got funded, and why it is better than anything the fitness industry has produced on the same subject.
What the job actually does to a neck
Peak lateral neck muscle force in flight: 50% to 257% of maximum voluntary contraction, mean 84.8%. The pilot who reached 257% sustained an acute injury that interrupted the flight. Cervical erector spinae at 4 G with rotation: 28.2% to 189.7% MVC.
The angular thresholds that govern everything on this site come from this literature: joint reaction forces at C7–T1 rise very rapidly beyond roughly 15° of flexion, 30° of extension, and 35° of axial rotation.
“Checking six” — rotating while extended to look up and behind — is named as the highest-risk head movement under load.

And for rotary-wing: UH-60 aviators spend 32.52% of flight time in severe cervical twist — against 0.58% in severe flexion. A third of the sortie in the position with the tightest angular tolerance.
The protocols that have been run
| Study | Population | Frequency | Length | Session | Result |
|---|---|---|---|---|---|
| Murray 2020 | Royal Danish AF helicopter aircrew | 3×/wk | 20 wk | 20 min | Extension MVC up in trained, down in reference (p=0.018) |
| Rausch 2021 | High-performance aircraft personnel | 3×/wk | 12 wk | 60 min | MRI volume +6.6–8.3%; %MVC under helmet significantly reduced |
| Chayrez 2024 | USAF student fighter pilots | 3×/wk | 8 wk | 10–15 min | Cervical endurance hold +33.6% overall, +55.7% at one base |
| Luo 2026 | Aviation cadets | 3×/wk | 12 wk | 25 min | Weighted helmet kept improving to wk 12; bands plateaued at wk 6 |
| AD1149927 | Rotary-wing aircrew | 5×/wk | 6 wk | — | 2 × 10–15 reps, 5 band exercises; CROM up, extension strength up |
Every one of them uses three sessions a week except the band protocol, which used five at a lower per-session dose.

The finding that matters most
Rausch’s group is the only one that measured both maximum strength and operational effort, and the difference is the most useful result in this literature.
Isometric strength gains were real but modest — extension +6.8%, flexion +17.7%, rotation ±22.9%.
The change that mattered operationally was different: after training, the muscle activity required to hold the head up while wearing the helmet fell significantly in the trained group and not in controls (p=0.01, and p<0.01 with night vision goggles added).
That is the mechanism by which neck training helps anyone in a sustained-load role. Not that you can generate more force — that the force your job demands becomes a smaller fraction of what you have.
Programming for aircrew
Three sessions a week. Every protocol converges here.
Rotation deliberately and seriously, given the 32.52% figure and the check-six risk. Almost no equipment loads it; manual resistance does.
Train rotation in neutral, never combined with extension under load. The one position the literature singles out as highest-risk is the one to avoid replicating with added resistance.
Weighted headgear replicates the demand directly and has the best controlled evidence. Half- kilogram increments to a ceiling around 3 kg over twelve weeks.
Bias toward endurance. Sorties are long. The cadet trial’s endurance outcome was the one that separated the modalities.
Bands are an on-ramp, not a destination. Elastic resistance of any grade produces roughly 15% MVC — the equivalent of 1 G. Aircrew routinely operate at three to five times that.
The adherence problem, which is the real one
In the twenty-week Danish trial, only 29% of participants trained regularly — despite supervision, inside working hours, as part of their job, in a population whose careers depend on cervical fitness.
Among those who did comply, cervical extension strength rose 6.0 ± 5.4 Nm against the reference group’s 2.4 Nm decline, with a between-group p of 0.001 — roughly triple the intention-to-treat effect.
The programme worked. Seven in ten people did not do it.
For anyone designing a unit-level intervention, that finding matters more than any programming detail on this page. A ten-minute session that gets done three times a week beats a twenty-five-minute session that does not.
