abstract = {The purpose of this study was to measure peak linear and rotational head acceleration in women’s collegiate soccer and explore the variations in acceleration across different strategic scenarios. Game videos from 14 games were used to identify the strategic scenario in which the athlete headed the ball. Strategic scenarios included: bounce, secondary header, punt, throw-in, goal kick, corner kick, and kick. Peak linear and rotational accelerations were measured using the Smart Impact Monitor (Triax Technologies Inc., Norwalk, CT). Goal kick (38.8 ± 19.4 g, p = 0.001, \ss = 8.9; 9.3 ± 3.9 krad/s2, p = 0.004, \ss = 1.9) and punt (36.0 ± 15.1 g, p = 0.055, \ss = 6.3; 10.1 ± 4.8 krad/s2, p = 0.002, \ss = 2.5) impacts resulted in higher linear and rotational head accelerations than the base variable, kick (30.0 ± 19.5 g; 7.5 ± 4.1 krad/s2). This suggests that limiting headers from goal kicks and punts in younger athletes who are still learning proper heading technique may limit cumulative linear and rotational accelerations. © 2016 Informa UK Limited, trading as Taylor \& Francis Group.},

abstract = {Background: Given questions about "lower thresholds" for concussion, as well as possible effects of repetitive concussion and chronic traumatic encephalopathy (CTE), and associated controversy, there is increasing interest in "subconcussive" blows and their potential significance. Objective: A formative review with critical examination of the developing literature on subconcussive blows in athletes with an emphasis on clinical outcomes. Methods: Studies of biomechanical, performance and/or symptom-based, and neuroimaging data were identified via PubMed search and critically reviewed. Five studies of symptom reporting/performance and 4 studies of neuroimaging were included. Results: The relation between biomechanical parameters and diagnosed concussion is not straightforward (ie, it is not the case that greater and more force leads to more severe injury or cognitive/behavioral sequelae). Neuropsychological studies of subconcussive blows within a single athletic season have failed to demonstrate any strong and consistent relations between number and severity of subconcussive events and cognitive change. Recent studies using neuroimaging have demonstrated a potential cumulative effect of subconcussive blows, at least in a subset of individuals. Conclusion: Human studies of the neurological/neuropsychological impact of subconcussive blows are currently quite limited. Subconcussive blows, in the short-term, have not been shown to cause significant clinical effects. To date, findings suggest that any effect of subconcussive blows is likely to be small or nonexistent, perhaps evident in a subset of individuals on select measures, and maybe even beneficial in some cases. Longerterm prospective studies are needed to determine if there is a cumulative dose effect. © 2016 Wolters Kluwer Health, Inc.},
