For fighter pilots, Special Operations personnel, and ground combat forces operating under head-supported mass, the physics of the cervical spine matters.
Add night-vision goggles, communications equipment, and other mission-essential systems to a ballistic helmet, and the neck must repeatedly stabilize and move that mass—often under fatigue, acceleration, and non-neutral positions.
The question is not simply how much weight is present. It is where that weight is positioned, head angle, acceleration, and repetition.
A 2026 Military Medicine study of 284 Special Operations combat soldiers documented 1,090 cervical spine injuries. 91% occurred while wearing head-supported mass during military activities, and 88% reported operationally related cervical pain in the prior 12 months (Sell TC, et al. Military Medicine. 2026.). Newman et al. also found that increasing helmet mass and aircraft acceleration increases cervical spine loading during operational fast-jet head movements (Newman P, et al. J Sci Med Sport. 2022;25:855–860.).
So how should those responsible for warfighter readiness prepare the neck for those demands? Not by simply asking, “How much weight can we put on the head?” The better question: How do we progressively develop cervical strength, endurance, neuromuscular control, and tolerance while controlling mechanical load?
In a 2024 Military Medicine study, F-16 student pilots at Luke AFB and F-35 student pilots at Eglin AFB completed an 8-week standardized Spine Training Program. At Eglin, external resistance was introduced only after full range of motion and adequate neuromuscular control were demonstrated, using CerviFit®. Male F-35 student pilots improved Cervical Endurance Hold performance by 55.7% (P
