The aim of the current study  was to identify the  head  impact kinematics and exposure  not  associated  with  purposeful  heading  of  the  ball  in  male  youth  soccer. Headband-mounted sensors were used to monitor the head kinematics of male junior varsity and middle school teams during games. Video analysis of sensor-recorded events was used to code impact mechanism, surface and site. Junior varsity players had non-header impact rates of 0.28 per athlete-exposure (AE) and 0.37 per player-hour (PH), whereas middle school players had relatively lower non-header impact rates of 0.16 per AE and 0.25 per PH. Such impact rates fell within the large range of values  reported  by  previous  studies,  which  is  likely  affected  by sensor type  and  recording  trigger  threshold.  The  most common  non-header  impact  mechanism  in junior  varsity  soccer  was  player  contact,  whereas  ball-to-head  was  the  most common non-header impact mechanism in middle school soccer. Non-header impacts for junior varsity players had median peak kinematics of 31.0 g and 17.4 rad\/s. Non-header impacts for middle school players had median peak kinematics of 40.6 g and 16.2 rad\/s. For non-header impacts, ball impacts to the rear of the head the highest peak kinematics recorded by the sensor. Such data provide targets for future efforts in injury prevention, such as officiating efforts to control player-to-player contact.<\/jats:p>","DOI":"10.34107\/yhpn9422.04106","type":"journal-article","created":{"date-parts":[[2021,9,16]],"date-time":"2021-09-16T21:40:47Z","timestamp":1631828447000},"page":"106-113","source":"Crossref","is-referenced-by-count":3,"title":["NON-HEADER IMPACT EXPOSURE AND KINEMATICS OF MALE YOUTH SOCCER PLAYERS"],"prefix":"10.34107","volume":"57","author":[{"name":"Center for Injury Research and Prevention, Children\u2019s Hospital of Philadelphia, Philadelphia, PA, USA","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Declan A.","family":"Patton","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colin M.","family":"Huber","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Center for Injury Research and Prevention, Children\u2019s Hospital of Philadelphia, Philadelphia, PA, USA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Department of Bioengineering, University of Pennsylvania, Philadelphia, PA, USA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susan S.","family":"Margulies","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"Wallace H.
