Effect of soccer heading ball speed on S100B, sideline concussion assessments and head impact kinematics
Abstract Objective : To examine the effect of soccer heading ball speed on S-100B serum concentration , concussion sideline assessment s and linear head impact acceleration . Methods : Sixteen division I soccer players participated in this pre-test post-test design study . Athletes performed five st and ing headers over a 10 minute period at 30 ( n = 5 ) , 40 ( n = 5 ) or 50 ( n = 6 ) miles per hour ( mph ) ( r and omized ) . S-100B serum concentration ( ng mL−1 ) and sideline concussion assessment s were measured prior to and post-heading . Peak result ant linear head acceleration ( gravitational units ; g ) was measured during soccer heading . Results : No statistically significant interaction effects were identified between ball velocity groups over time on S100B ( effect sizes ranged from 0.03–0.23 ) or concussion assessment s tests . There was a non-significant increase ( p = 0.06 ) in head impact acceleration from the 30 ( 30.6 ; SD = 6.2 g ) to 50 mph ( 50.7 ; SD = 7.7 g ) ball speed . Conclusions : In this controlled setting , an acute bout of soccer heading across various ball velocities did not affect S100B or concussion assessment test scores . These findings are preliminary , as the small sample size in each group may have played a role in the lack of significant findings
