Background: Ankle inversion injuries are one of the most common and burdensome
injuries in athletic populations. Research that prospectively identifies characteristics
associated with this injury is lacking. This prospective study compared baseline
anthropometric and biomechanical gait characteristics of military recruits who sustained
an ankle inversion injury during training, with those who remained injury-free.
Methods: Bilateral plantar pressure and three-dimensional lower limb kinematics were
recorded in 1065 male, injury-free military recruits, during barefoot running. Injuries that
occurred during the 32-week recruit training programme were subsequently recorded.
Data were compared between recruits who sustained an ankle inversion injury during
training (n=27) and a sample (n=120) of those who completed training injury-free. A
logistic regression analysis was used to identify risk factors for this injury.
Findings: A narrower bimalleolar width and an earlier peak pressure under the fifth
metatarsal were predictors of ankle inversion injury. Those who sustained an ankle
inversion injury also had a lower body mass, body mass index, and a smaller calf girth
than those who completed training injury-free.
Interpretation: Anthropometric and dynamic gait characteristics have been identified
that may predispose recruits to an ankle inversion injury during Royal Marine recruit
training, allowing identification of recruits at higher risk at the start of training.
