Participants included 14 youth female soccer athletes across 2 club-level teams at different age levels (team 1, ages 12\u201313\u00a0y; team 2, ages 14\u201315\u00a0y). Head impact and time-synchronized video data were collected for 66 practices and games. Video data were reviewed to characterize the type and frequency of contact experienced by each athlete. A total of 2216 contact scenarios were observed; heading the ball (n\u2009=\u2009681, 30.7%) was most common. Other observed contact scenarios included collisions, dives, falls, and unintentional ball contact. Team 1 experienced a higher rate of headers per player per hour of play than team 2, while team 2 experienced a higher rate of collisions and dives. A total of 935 video-verified contact scenarios were concurrent with recorded head kinematics. While headers resulted in a maximum linear acceleration of 56.1<jats:italic>g<\/jats:italic>, the less frequent head-to-head collisions (n\u2009=\u20096) resulted in a maximum of 113.5<jats:italic>g<\/jats:italic>. The results of this study improve the understanding of head impact exposure in youth female soccer players and inform head impact exposure reduction in youth soccer.<\/jats:p>","DOI":"10.1123\/jab.2020-0071","type":"journal-article","created":{"date-parts":[[2020,11,3]],"date-time":"2020-11-03T13:46:12Z","timestamp":1604411172000},"page":"36-42","source":"Crossref","is-referenced-by-count":25,"title":["Characterization of On-Field Head Impact Exposure in Youth Soccer"],"prefix":"10.1123","volume":"37","author":[{"given":"Brian T.","family":"Tomblin","sequence":"first","affiliation":[{"name":"1Wake Forest School of Medicine"},{"name":"2Virginia-Tech-Wake Forest University School of Biomedical Engineering & Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.
