Head Impact Exposure and Neurologic Function of Youth Football Players.

TLDR
Whereas youth football players can experience remarkably similar head impact forces as high school players, cumulative subconcussive HIE throughout one youth football season may not be detrimental to short-term clinical measures of neurologic function.

Head Impact Exposure in Youth Football

TLDR
Although less frequent, youth football can produce high head accelerations in the range of concussion causing impacts measured in adults, and youth football practices should be modified to eliminate high impact drills that do not replicate the game situations.

Head impact exposure sustained by football players on days of diagnosed concussion.

TLDR
Players sustained more impacts and impacts of higher severity on days of diagnosed concussion than on days without diagnosed concussion and those associated with peak linear acceleration are the best predictors of immediately diagnosed concussion.

Head Impact Exposure in Junior and Adult Australian Football Players

TLDR
There was a significant increase in the frequency of head impacts for midfielders in both grades once the authors accounted for player position and, by targeting education and prevention strategies, a decrease in the incidence of sports-related concussion may result.

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.

The Ability of American Football Helmets to Manage Linear Acceleration With Repeated High-Energy Impacts.

CONTEXT Football players can receive up to 1400 head impacts per season, averaging 6.3 impacts per practice and 14.3 impacts per game. A decrease in the capacity of a helmet to manage linear

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.

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

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.

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.

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.

Head impacts during high school football: a biomechanical assessment.

TLDR
This is the first to provide a biomechanical characterization of head impacts in an interscholastic football team across a season of play and these high school football athletes appeared to sustain greater accelerations after impact than their older counterparts did.

IN VIVO STUDY OF HEAD IMPACTS IN FOOTBALL: A COMPARISON OF NATIONAL COLLEGIATE ATHLETIC ASSOCIATION DIVISION I VERSUS HIGH SCHOOL IMPACTS

TLDR
Differences in the frequency and magnitude of head acceleration after impact exist between a Division I college team and a high school team, and skill position players typically sustain the highest-level impacts.

Analysis of linear head accelerations from collegiate football impacts

TLDR
This study presents an extremely large data set from human head impacts that provides valuable insight into the lower limits of head acceleration that cause mild traumatic brain injuries.

Characteristics of head impacts sustained by youth ice hockey players

This study aimed to measure the magnitude of head impacts sustained by 14 male, youth (13 years old) ice hockey players wearing instrumented helmets, and to compare impacts across event type

Concussion in Professional Football: Location and Direction of Helmet Impacts—Part 2

TLDR
The location, direction, and severity of helmet impacts causing concussion in the National Football League have been defined from analysis of game video and laboratory reconstruction and define the circumstances in which helmets need to reduce head injury risks in professional football.

TLDR
The primary finding of this study is that the helmet-mounted accelerometer system proved effective at collecting thousands of head impact events and providing contemporaneous head impact parameters that can be integrated with existing clinical evaluation techniques.

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.

Head acceleration is less than 10 percent of helmet acceleration in football impacts.

TLDR
It is shown that the response of the head and the helmet vary greatly and the in-helmet system matches theHead acceleration is less than 10 percent of helmet acceleration in football impacts; moreover, the HIT System is able to accurately measure the head acceleration.
