While kinematics describes the inertial response of the brain to impact, they do not fully capture the dynamic brain response. Strain, a measure of the tissue-level response of the brain, may be a better predictor of injury. In this study, kinematic and strain metrics were compared to contact characteristics in youth football. Players on 2 opposing teams were instrumented with head impact sensors to record impact kinematics. Video was collected to identify contact scenarios involving opposing instrumented players (ie,\u00a0paired contact scenarios) and code contact characteristics (eg,\u00a0player role, impact location). A previously validated, high-resolution brain finite element model, the atlas-based brain model, was used to simulate head impacts and calculate strain metrics. Fifty-two paired contact scenarios (n\u2009=\u2009105 impacts) were evaluated. Lighter players tended to have greater biomechanical metrics compared to heavier players. Impacts to the top of the helmet were associated with lower strain metrics. Overall, strain was better correlated with rotational kinematics, suggesting these metrics may be better predictors of the tissue-level brain response than linear kinematics. Understanding the effect of contact characteristics on brain strain will inform future efforts to improve sport safety.<\/jats:p>","DOI":"10.1123\/jab.2021-0098","type":"journal-article","created":{"date-parts":[[2022,4,28]],"date-time":"2022-04-28T12:10:11Z","timestamp":1651147811000},"page":"136-147","source":"Crossref","is-referenced-by-count":6,"title":["Head Impact Kinematics and Brain Deformation in Paired Opposing Youth Football Players"],"prefix":"10.1123","volume":"38","author":[{"given":"Gabriella M.","family":"Milef","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"Department of Biomedical Engineering and Sciences, Virginia Tech\u2013Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Logan E.","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"Department of Biomedical Engineering and Sciences, Virginia Tech\u2013Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniella M.","family":"DiGuglielmo","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"Department of Biomedical Engineering and Sciences, Virginia Tech\u2013Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanner D.","family":"Payne","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanner M.","family":"Filben","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"Department of Biomedical Engineering and Sciences, Virginia Tech\u2013Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jillian E.","family":"Urban","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"Department of Biomedical Engineering and Sciences, Virginia Tech\u2013Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joel D.","family":"Stitzel","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"Department of Biomedical Engineering and Sciences, Virginia Tech\u2013Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"4","key":"r1","series-title":"Ann Biomed Eng","doi-asserted-by":"publisher","first-page":"976","DOI":"10.1007\/s10439-012-0530-7","article-title":"Head impact exposure in youth football","volume":"40","author":"Daniel RW","year":"2012","unstructured":"Daniel RW, Rowson S, Duma SM.
