Eleven male and female participants aged 13-18 years completed 10 frontal or oblique soccer headers. Linear acceleration and angular velocity of the head were captured using the Prevent Biometrics boil-and-bite Impact Monitoring Mouthguard (IMM). Head kinematics time series were applied to the Brain Simulation Research Platform (BSRP) FE head model. Frontal headers resulted in significantly (p<0.001) higher mean peak linear acceleration (17.5±0.5 g) but significantly (p<0.001) lower mean peak angular acceleration (1142±45 rad/s2) than oblique headers (12.3±0.4 g, 1431±66 rad/s2). Frontal headers had similar peak MPS95 values compared to oblique headers (4.8±1.1% vs. 4.5±1.2%, p=0.128). Using equivalent loading conditions, frontal and oblique headers did not differ in peak MPS95 despite oblique headers having significantly higher angular kinematics, which is associated with brain tissue strains. Comparisons with previous results from a validated FE head model suggest that the BSRP FE head model has potential for simulating on-field head impact sensor data, especially considering the reduced computational time, but estimations of strain and model comparisons with more severe on-field sporting impacts are needed.","PeriodicalId":91010,"journal":{"name":"Conference proceedings.

Two BMI (Body Mass Index) groups (non-obese and obese) with a maximum abbreviated injury scale (MAIS) in the spine region of ≥2 (MAIS_6S 2+) were categorised and compared. The fracture types were assessed based on AIS for each occupant. Univariate analyses were conducted to investigate the association between analytic morphomics measures and thoracolumbar spine fracture. The results indicate that MAIS 2+ injury occurred mainly in severe crashes with high delta-V and large intrusion. Transverse process fractures were the most common AIS 2+ fractures, followed by minor compression type fractures (≤ 20% anterior height). Compared to the non-obese occupants, the majority of obese occupants sustained transverse process fractures at lumbar vertebra with a higher incidence ratio. A statistical analysis was conducted, using vehicle, demographic, and morphomic variables, to explain the difference between transverse process fractures and vertebra body compression fractures. Transverse process fractures were related to BMI and vehicle factors (intrusion) in the obese group. In addition, morphomics related to fat distribution, muscle area, and cortical bone density are the major difference between non-obese and obese occupants.","PeriodicalId":91010,"journal":{"name":"Conference proceedings.

The objective of this study was to pair estimated impact velocities with linear acceleration data collected from on-field head impacts in youth football to inform youth-specific helmet testing methods. A total of 49 youth football players received helmets instrumented with accelerometer arrays to measure head acceleration throughout the season. Using video recordings of games from a single camera, impact velocities were estimated for impacts with known acceleration magnitudes. On-field accelerations ranged from 40 to 85 g, while impact velocities ranged from 0.5 to 5.5 m/s. The average error associated with these velocity estimates was below 10%, and a zoomed-in camera view provided results more consistent with true velocity. Velocities estimated from direct helmet-to-helmet impacts matched more closely with linear acceleration than other kinds of impacts. These findings may be used to inform testing methods/conditions that are more representative of impacts experienced by youth football players.","PeriodicalId":91010,"journal":{"name":"Conference proceedings.
