PURPOSE This study compares the frequency and severity of head impacts sustained by football players on days with and without diagnosed concussion and to identify the sensitivity and specificity of single-impact severity measures to diagnosed injury. METHODS One thousand two hundred eight players from eight collegiate football teams and six high school football teams wore instrumented helmets to measure head impacts during all team sessions, of which 95 players were diagnosed with concussion…

The Effect of Head Impact Location on Day of Diagnosed Concussion in College Football.
TLDR
It may be more difficult to mitigate concussive forces sustained in impacts to the top and sides of the head than the front of theHead, which falls in line with previous research demonstrating that reduced impact magnitudes may lessen concussion risk.
Timing of concussion diagnosis is related to head impact exposure prior to injury.
TLDR
Conussions diagnosed immediately after an impact event are associated with the highest kinematic measures, whereas those characterized by delayed diagnosis are preceded by a higher number of impacts.
Comparison of Head Impact Exposure Between Concussed Football Athletes and Matched Controls: Evidence for a Possible Second Mechanism of Sport-Related Concussion
Studies of football athletes have implicated repetitive head impact exposure in the onset of cognitive and brain structural changes, even in the absence of diagnosed concussion. Those studies imply
Biomechanics of head impacts associated with diagnosed concussion in female collegiate ice hockey players.
Measuring Head Impact Exposure and Mild Traumatic Brain Injury in Humans
Helmeted sports such as football offer a unique opportunity to study head injury biomechanics in live human subjects. Impact reconstruction using game videos and real-time measurements of head
Correlation of Concussion Symptom Profile with Head Impact Biomechanics: A Case for Individual-Specific Injury Tolerance.
TLDR
Investigating the relationship between an array of biomechanical parameters measured for concussive impacts and the presentation and resolution of concussion symptoms found no association between impact location and presence of any individual symptom when ignoring severity grade, and tolerance to head acceleration might be individual-specific, meaning similar biomechanicals inputs can produce different injury presentations between individuals.
Head Impact Biomechanics and Helmet Performance in Youth Football
The research presented in this thesis aims to improve the knowledge of head impact biomechanics in youth football players by analyzing head impact exposure of youth football players and the
Head Impact Density: A Model To Explain the Elusive Concussion Threshold.
TLDR
The data suggest that the biomechanical threshold for concussion fluctuates downwardly with a greater impact magnitude and number with a return to pre-impact levels with time, suggesting physiological vulnerability to repeated head impacts.
Practice type effects on head impact in collegiate football.
TLDR
The findings suggest that regulation of practice equipment could be a fair and effective way to substantially reduce subconcussive head impact in thousands of collegiate football players.
Factors Affecting Head Impact Exposure in College Football Practices: A Multi-Institutional Study
TLDR
Differences between individuals accounted for 48% of the variance in head impact exposure in practice, demonstrating the importance of considering head impact Exposure on a subject-specific basis rather than estimating head impact exposed from aggregate data.

Validation of Concussion Risk Curves for Collegiate Football Players Derived from HITS Data
TLDR
Analysis of data from 37,128 head impacts collected at Virginia Tech during games from 2006 to 2010 demonstrates that simple biomechanical parameters that can be measured by the HIT System possess a high level of power for predicting concussion.
Head impact exposure in collegiate football players.
Frequency and location of head impact exposures in individual collegiate football players.
TLDR
The frequency of head impacts and the location on the helmet where the impacts occur are functions of player position and session type, as well as the possible effects of repeated subconcussive impacts in football.
MEASUREMENT OF HEAD IMPACTS IN COLLEGIATE FOOTBALL PLAYERS: RELATIONSHIP BETWEEN HEAD IMPACT BIOMECHANICS AND ACUTE CLINICAL OUTCOME AFTER CONCUSSION
TLDR
It is suggested that football players are concussed by impacts to the head that occur at a wide range of magnitudes and that clinical measures of acute symptom severity, postural stability, and neuropsychological function all appear to be largely independent of impact magnitude and location.
HEAD IMPACT SEVERITY MEASURES FOR EVALUATING MILD TRAUMATIC BRAIN INJURY RISK EXPOSURE
TLDR
This study is the first to the authors' knowledge to quantify improvements in the sensitivity of a biomechanical measure to incidence of concussion when impact location is considered and develops a novel measure of head impact severity combining these measures into a single score that better predicts the incidence of concussions.
Biomechanical properties of concussions in high school football.
TLDR
A similar threshold to concussion in adolescent athletes compared with their collegiate and professional counterparts suggests an equal concussion risk at all levels of play.
Spectrum of acute clinical characteristics of diagnosed concussions in college athletes wearing instrumented helmets: clinical article.
TLDR
The authors used data gathered as part of a multiinstitutional longitudinal study of the biomechanics of head impacts in helmeted collegiate athletes to characterize what signs, symptoms, and clinical histories were used to designate players as having sustained concussions.
Magnitude of head impact exposures in individual collegiate football players.
TLDR
The findings of this study provide essential data for future investigations that aim to establish the correlations between head impact exposure, acute brain injury, and long-term cognitive deficits.
Epidemiology of Concussion in Collegiate and High School Football Players
TLDR
Players who sustained one concussion in a season were three times more likely to sustain a second concussion in the same season compared with uninjured players, and contact with artificial turf appears to be associated with a more serious concussion than contact with natural grass.
Rotational Head Kinematics in Football Impacts: An Injury Risk Function for Concussion
TLDR
Characterizing the rotational kinematics of the head associated with concussive impacts using a large head acceleration dataset collected from human subjects provides critical insight into injury mechanisms, human tolerance to mechanical stimuli, and injury prevention techniques.
