The objective of this study was to compare the capacity of vinyl nitrile and expanded polypropylene, two materials commonly used in ice hockey helmets, to reduce the peak linear acceleration, peak angular acceleration, and head injury criterion values during a direct impact to a hybrid III headform. Six different ice hockey helmets were tested using a pneumatic linear impactor at velocities similar to those in hockey. The results showed that helmets using expanded polypropylene foam liners are…

Protective capacity of an ice hockey goaltender helmet for three events associated with concussion
The results demonstrated the tested ice hockey goaltender helmet was well designed to manage fall and puck impacts but does not consistently protect against shoulder collisions and an opportunity may exist to improve helmet designs to better protect goaltenders from shoulder collisions.
Ten years later: Ice hockey helmet impact mechanics change with age
This longitudinal 10-year study investigated the effects of inventory aging on ice hockey helmets’ impact attenuation characteristics. Three unused helmet models with different foam padding materials
Protective Capacity of Ice Hockey Helmets against Different Impact Events
The results suggest that the ice hockey helmet tested is unable to reduce engineering parameters below reported ranges of concussion and TBI for impact conditions which do not represent a drop against a rigid surface.
The application of brain tissue deformation values in assessing the safety performance of ice hockey helmets
This research was undertaken to examine a new method for assessing the performance of ice hockey helmets. It has been proposed that the current centric impact standards for ice hockey helmets,
Mitigation of Linear Accelerations and Shear Forces During Drop Head Simulated Falls
The danger and risk associated with ice hockey has led to the development of new helmet technologies and testing protocols to minimize the risk of traumatic brain injuries or concussions. Researchers
Examination of the relationship between peak linear and angular accelerations to brain deformation metrics in hockey helmet impacts
The results indicated that when the helmet is examined using peak resultant linear acceleration alone, they are similar and protective, but when a 3D brain deformation response is used to examine the helmets, there are risks of brain injury with lower linear accelerations which would pass standard certifications for safety.
Comparison of Ice Hockey Goaltender Helmets for Concussion Type Impacts
A clear opportunity exists to design new goaltender helmets which can better protect ice hockey goaltenders from collisions, and current ice hockey goaltender helmets can be optimized for protection against falls and puck impacts.
Comparative analysis of helmeted impact response of Hybrid III and National Operating Committee on Standards for Athletic Equipment headforms
As advanced helmet testing methodologies are developed, the effect headform selection may have on the biomechanical impact response must be considered. This study sought to assess response
Influence of VN foam liner density on impact attenuation of an ice hockey helmet
The current Canadian Standards Association ice hockey helmet testing methodology utilizes a monorail drop to simulate falls (CSA, 2015). Linear acceleration is used as a performance criterion, which
Dynamic Head Response and Maximum Principal Tissue Strain for Helmeted (American Football) and Non-helmeted Impacts
The football helmet is credited with reducing the incidence of traumatic brain injury by protecting against linear impacts. Despite this, concussion rates remain high. It is proposed that linear


Survival by design: Head protection
Protection of the head in collisions can be achieved in two ways - by padding the head (helmet) or by padding everything the head can come in contact with during a collision. But it would probably be
Influence of impact direction on the human head in prediction of subdural hematoma.
It was found that the influence of impact direction had a substantial effect on the intracranial response and it is suggested that an evaluation of the synergistic terms is necessary to further improve the injury prediction.
An epidemiological study of high school ice hockey injuries
Increased risks of injury were associated with multiple health-care provision variables and equipment utilized and potential strategies are identified as a result of these findings.
Human Head Tolerance to Sagittal Impact Reliable Estimation Deduced from Experimental Head Injury Using Subhuman Primates and Human Cadaver Skulls
The results indicate that the occurrence and severity of concussion, cerebral contusion, and skull fracture in the monkeys depended on translational vs. rotational impact, contact area size, amplitude and direction of the resultant head acceleration, and frontal vs. occipital impact direction.
Head Injury in Athletes
The historical developments in the recognition and care of athletes with head injuries, the current theory of the pathophysiology and biomechanics of these insults, and the recommended management strategy, including return-to-play criteria are reviewed.

The risk of injury in men's collegiate ice hockey is much greater during games than during practices, and Concussions are a main cause for time lost and remain an area of major concern.
Analysis and Evolution of Head Injury in Football
Significant declines in both the incidence and severity of head injury have been observed and the enhanced safety records in football can be attributed to the application of more stringent tackling regulations as well as the evolving football helmet.
