PURPOSE: The purpose of this study was to compare ankle power, peak plantarflexion moment, and ankle range of motion (ROM) between injured and uninjured Division-I cross-country athletes. METHODS: Six Division-I female cross-country athletes (height 164.7 ± 4.1 cm; weight 52.0 ± 3.1 kg) reported prior to the start of the cross-country season. Upon providing informed consent, athletes completed 5 running trials at a preferred pace over a 15-m runway in a laboratory equipped with ten 3D motion capture infrared cameras. Kinetic data were collected using three embedded force platforms within a 15-m runway. Ankle ROM, peak plantarflexion moment, and average ankle plantarflexion power were calculated. Injury reports were obtained from the team’s certified athletic trainer at the end of the season. These reports allowed for the stratification of athletes into injured and uninjured groups. Data from six athletes were used for the current analysis, thus Hedges’ g measures were used to identify effect size. RESULTS: Three athletes sustained left foot injuries during the season. Injury status had a small effect prospectively on plantarflexor power (g=0.25) and ankle ROM (g=0.25), and a medium effect on peak plantarflexor moment (g=0.68) of the injured ankle. Injured athletes exhibited lower magnitudes of the variables of interest compared to uninjured athletes: average plantarflexor power (274.8 ± 53.5 and 306.1 ± 101.4 Nm/s respectively), less ankle ROM (41.5 ± 4.3 and 44.1 ± 8.3°), and lower peak plantarflexor moments (124.1 ± 12.3 and 140.0 ± 17.8 Nm). CONCLUSIONS: Based on the results of the current study, the measured variables, particularly peak plantarflexion moment, may be of interest when investigating foot injury risk. The athletes in the current study may already be altering their motion to protect the at-risk limb. Longitudinal studies with additional data points and robust sample sizes are necessary to determine changes in running gait which may indicate increased risk of injury. This information has the potential to inform pre-screening gait analyses and subsequent coaching and clinical interventions.
