Additionally, soccer players are frequently exposed to nonconcussive impacts from intentionally heading the ball, a fundamental component of the sport. There have been many studies on head impact exposure in soccer, but few focus on soccer practices or practice activities. This study aimed to characterize the frequency and magnitude of head impacts in National Collegiate Athletic Association Division I female soccer practice activities using a custom-fit instrumented mouthpiece. Sixteen players were instrumented over the course of 54 practice sessions. Video analysis was performed to verify all mouthpiece-recorded events and classify practice activities. Category groupings of practice activities include technical training, team interaction, set pieces, position-specific, and other. Differences in head impact rates and peak resultant kinematics were observed across activity types and category groupings. Technical training had the highest impact rate compared to other category groupings. Impacts occurring during set piece activities had the highest mean kinematic values. Understanding drill exposure can help inform coaches on training plans aimed to reduce head impact exposure for their athletes.<\/jats:p>","DOI":"10.1123\/jab.2022-0134","type":"journal-article","created":{"date-parts":[[2023,5,20]],"date-time":"2023-05-20T17:12:54Z","timestamp":1684602774000},"page":"209-216","source":"Crossref","is-referenced-by-count":3,"title":["Head Impact Exposure in Female Collegiate Soccer by Activity Type"],"prefix":"10.1123","volume":"39","author":[{"given":"Mary Frances","family":"Segars","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"School of Biomedical Engineering and Sciences, Virginia Tech\u2014Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2572-0093","authenticated-orcid":true,"given":"Tanner M.","family":"Filben","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Wake Forest School of Medicine, Winston-Salem, NC, USA"},{"name":"School of Biomedical Engineering and Sciences, Virginia Tech\u2014Wake Forest University, Winston-Salem, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2603-0841","authenticated-orcid":true,"given":"N.
