An isometric neck strengthening program does not improve neck strength in elite women's football-code athletes: A randomised controlled trial.

Neck strength is often discussed in football-code sports because of concerns about head and neck injury risk, so researchers wanted to know whether adding targeted isometric neck exercises to an athlete's regular training could actually make the neck stronger. This trial compared elite women's soccer and Australian football players who did their normal strength and conditioning program against a group that also added isometric neck strengthening exercises three times a week for twelve weeks. Both groups got stronger over the twelve weeks in most measures, but the added neck exercises did not produce extra strength gains compared with standard training, except for one specific measure, left-side lateral neck flexion, where a difference was found. The finding is interesting because it challenges the assumption that a simple add-on neck program will meaningfully boost neck strength beyond what athletes already achieve through general training.

The main limitation is the small sample of forty athletes, and the authors note this specific program's results may not apply to other exercise designs or to less elite athletes.

If you're an athlete or someone who follows sports science, you may have heard that stronger neck muscles could help protect against certain injuries in contact sports. This study looked at whether adding a specific neck-strengthening program to elite women footballers' usual training routines would make their necks noticeably stronger. Both the group doing extra neck exercises and the group sticking with standard training got stronger over the twelve-week season, but the extra neck work didn't add any real benefit beyond what standard training already provided, apart from one specific movement direction.

That's a useful but humbling finding: it means simply tacking on isometric neck exercises to an existing program may not be the boost people hope for. It's important to remember this was a small trial with forty athletes, all playing at an elite level, so it doesn't tell us whether a different kind of neck program, or the same program used by less experienced athletes, might work differently.

This trial addresses a specific and practical question for those working with contact-sport athletes: does adding isometric neck strengthening to an already-established strength and conditioning program produce measurable strength gains beyond what general training delivers? Forty elite female footballers, drawn from soccer and Australian football, were randomised to a control group following standard training or an experimental group that also performed isometric neck exercises three times weekly for twelve weeks, with strength assessed via hand-held dynamometer at baseline, week seven, and week thirteen. The decisive result is that no significant group-by-time interaction was found across neck extensor, flexor, lateral flexor, or rotator strength, meaning the added exercises did not outperform standard training over time. All strength variables improved significantly within both groups across the twelve weeks, so gains occurred regardless of the extra intervention, and only one specific measure, left lateral flexion, showed a significant between-group difference. For practice, this suggests that this particular isometric protocol, layered onto an already robust strength and conditioning program in elite athletes, may not add strength benefit, though the abstract does not establish whether sport-specific variations or application in lower-level athletes would differ.

The small sample of forty athletes and single population studied limit how far these findings can be generalised.
