Abstract
Analyzing magnitude and frequency of head impacts in relation to impact location in collegiate soccer athletes
Context: Studying the location of head impacts may provide insight on potential preventative efforts. Objective:To explore the relationship between magnitude and frequency of head impact locations in soccer athletes. Design: Descriptive epidemiology study. Setting: Collegiate soccer fields. Patients or Other Participants: 9 men’s (age=18.67±1 yr, height=183.57±5.39 cm, mass=80.32±13.50 kg) and 19 women’s (age=19.42±1.43 yr, height=166.17±5.24 cm, mass=64.15±7.23 kg) soccer athletes. Interventions: Impact location (back, front, side, top) was used as the independent variable. Participants wore xPatch sensors for all games and practices. Each event was video recorded to verify impacts. Main Outcome Measure(s): Sensors collected linear (g) and rotational (deg/s2) acceleration. We calculated incidence rates (IRs) per 1000 exposures and incidence rate ratios (IRRs) with corresponding 95% confidence intervals (CIs). Results: Division III soccer athletes are likely to experience 2 head impacts every 10 exposures (IR=214.49, Cl=186.65-242.33). Participants were 2.33 times more likely to get hit on the side of the head (IR=113.83, Cl=93.55-134.11) than the front of the head (IR=48.92, Cl=35.62-62.21; IRR=2.33, CI=1.68-3.22). The effect of the location on linear (�23=34.23, P<.001) and rotational (�23=47.31, P<.001) acceleration were both significant. Further analysis showed that both linear (F3,227=12.52, P<.001, n2=.14) and rotational (F3,227=17.2, P<.001, n2=.19) acceleration were significantly altered by impact location. Conclusions: Our results may influence an increase in coaching emphasis, behavior modifications, and education in an effort to reduce head impacts, especially to the side of the head.
