Area of Science:

  • Sports Medicine
  • Biomechanics
  • Injury Prevention

Background:

  • Head impacts in football pose a significant risk of injury.
  • Current protective equipment may not fully mitigate head impact exposure.
  • Novel interventions are needed to reduce head trauma in athletes.

Purpose of the Study:

  • To evaluate the efficacy of a helmetless-tackling behavioral intervention.
  • To reduce head impacts among National Collegiate Athletic Association Division I football players.

Main Methods:

  • A randomized controlled clinical trial was conducted on 50 collegiate football players.
  • The intervention group practiced tackling without helmets and pads; the control group performed noncontact drills.
  • Head impacts were measured using impact sensors for each athlete-exposure (AE).

Main Results:

  • The intervention group experienced 30% fewer head impacts per AE compared to the control group by the end of the season.
  • Mean head impacts per AE were 9.99 ± 6.10 for the intervention group versus 13.84 ± 7.27 for the control group.
  • Statistical analysis confirmed a significant reduction in head impacts for the intervention group.

Conclusions:

  • Helmetless-tackling training is an effective intervention for reducing head impacts in collegiate football.
  • This behavioral approach offers a promising strategy for mitigating head trauma in athletes.
  • Further research can explore long-term effects and broader implementation.
