Further study is required to understand what types of subconcussive impacts might prove detrimental to cognition. We studied cadets at the US Air Force Academy engaged in boxing and physical development, measuring head impact motions during exercise with accelerometers. These head impact measures were compared with post-exercise memory performance. Investigators explored multiple techniques for characterizing the magnitude of head impacts. Boxers received more head impacts and achieved lower performance in post-exercise memory than non-boxers. For several measures of impact motion, impact intensity appeared to set an upper bound on post-exercise memory performance \u2013 stronger impacts led to lower expected memory performance. This trend was most significant when impact intensity was measured through a novel technique, applying principal component analysis to boxer motion. Principal component analysis measures also captured more distinct impact information than seven traditional impact measures also tested.<\/jats:p>","DOI":"10.1093\/milmed\/usy415","type":"journal-article","created":{"date-parts":[[2019,3,22]],"date-time":"2019-03-22T16:10:41Z","timestamp":1553271041000},"page":"206-217","source":"Crossref","is-referenced-by-count":8,"title":["Predictive Power of Head Impact Intensity Measures for Recognition Memory Performance"],"prefix":"10.1093","volume":"184","author":[{"given":"Daniel D","family":"Leeds","sequence":"first","affiliation":[{"name":"Computer and Information Sciences Department, Fordham University, John Mulcahy Hall \u2013 Room 340, 441 East Fordham Road, Bronx, NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"D\u2019Lauro","sequence":"additional","affiliation":[{"name":"United States Air Force Academy, Department of Behavioral Science and Leadership, 2354 Fairchild Drive, Suite 5L60, USAF Academy, CO"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian R","family":"Johnson","sequence":"additional","affiliation":[{"name":"Walter Reed Army Institute of Research, Center for Military Psychiatry and Neuroscience, 503 Robert Grant Ave, Silver Spring, MD"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2019,3,21]]},"reference":[{"issue":"5","key":"2019122605175599100_usy415C1","doi-asserted-by":"crossref","first-page":"375","DOI":"10.1097\/00001199-200609000-00001","article-title":"The epidemiology and impact of traumatic brain injury: a brief overview","volume":"21","author":"Langlois","year":"2006","journal-title":"J Head Trauma Rehabil"},{"issue":"3","key":"2019122605175599100_usy415C2","doi-asserted-by":"crossref","first-page":"159","DOI":"10.1097\/HTR.0000000000000138","article-title":"Subconcussive blows to the head: a formative review of short-term clinical outcomes","volume":"31","author":"Belanger","year":"2016","journal-title":"J Head Trauma Rehabil"},{"issue":"1","key":"2019122605175599100_usy415C3","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1016\/j.csm.2010.09.007","article-title":"Chronic traumatic encephalopathy: a potential late effect of sport-related concussive and subconcussive head trauma","volume":"30","author":"Gavett","year":"2011","journal-title":"Clin Sports Med"},{"issue":"5","key":"2019122605175599100_usy415C4","doi-asserted-by":"crossref","first-page":"1233","DOI":"10.3171\/2013.7.JNS121822","article-title":"Role of subconcussion in repetitive mild traumatic brain injury: a review","volume":"119","author":"Bailes","year":"2013","journal-title":"J Neurosurg"},{"issue":"22","key":"2019122605175599100_usy415C5","doi-asserted-by":"crossref","first-page":"1777","DOI":"10.1212\/WNL.0b013e3182582fe7","article-title":"Cognitive effects of one season of head impacts in a cohort of collegiate contact sport athletes","volume":"78","author":"McAllister","year":"2012","journal-title":"Neurology"},{"issue":"2","key":"2019122605175599100_usy415C6","doi-asserted-by":"crossref","first-page":"e57364","DOI":"10.1371\/journal.pone.0057364","article-title":"Evidence of cognitive dysfunction after soccer playing with ball heading using a novel tablet-based approach","volume":"8","author":"Zhang","year":"2013","journal-title":"PLoS One"},{"key":"2019122605175599100_usy415C7","doi-asserted-by":"crossref","first-page":"66","DOI":"10.1016\/j.ebiom.2016.10.029","article-title":"Evidence for acute electrophysiological and cognitive changes following routine soccer heading","volume":"13","author":"Di Virgilio","year":"2016","journal-title":"EBioMedicine"},{"issue":"1","key":"2019122605175599100_usy415C8","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s10439-011-0392-4","article-title":"Rotational head kinematics in football impacts: an injury risk function for concussion","volume":"40","author":"Rowson","year":"2012","journal-title":"Ann Biomed Eng"},{"issue":"3","key":"2019122605175599100_usy415C9","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1136\/bjsm.28.3.187","article-title":"Neuropsychological investigation of amateur boxers","volume":"28","author":"Butler","year":"1994","journal-title":"Br J Sports Med"},{"issue":"1","key":"2019122605175599100_usy415C10","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1177\/036354659302100117","article-title":"Does amateur boxing lead to chronic brain damage?
