Figure 2.

Distributions of the independent variables (peak magnitudes and durations in (a), and azimuth and elevation angles in (b)) used to generate head impact kinematics (cross: a_lin, circle: a_rot); (c) Illustration of a representative head impact condition (arrows in (a) and (b) identify the variable values used to combine and produce the head impact kinematics); (d) normalized acceleration and velocity temporal profiles. Kinematic variable values for the identified impact are: ${\mathbf{a}}_{\mathit{\text{rot}}}^{\mathit{p}}=4193\text{ rad}/{\mathrm{s}}^2$, Δt_rot=10.2 ms, ${\mathbf{a}}_{\mathit{\text{lin}}}^{\mathit{p}}=72.8\mathrm{g}$, Δt_lin=10.9 ms, θ_rot=153.7 deg, α_rot=33.5 deg, θ_lin=−26.3 deg, and α_lin=37.5 deg.
