The NCAA Injury Surveillance System (ISS) was used to evaluate head and neck injuries in twelve intercollegiate sports for 3–6 years through the 1990 season. Sports were categorized as those with and without mandated head protection. Prevalence of head and neck injuries were expressed as both a percentage of all reported injuries in a specific sport (%) as well as an injury rate (IR). In addition the primary injury mechanism was noted. Concussions were also listed as a percentage of all reported injuries in a sport and as an injury rate. Of the sports with no head protection, field hockey, men's soccer and women's soccer had the highest prevalence of head injuries and concussions expressed as both % or IR. Ice hockey and football had the highest head injury values of the sports with head protection. Wrestling and football showed the highest % and IR for neck injury.

ASTM International grants to the Subscriber and Authorized Users at the Subscriber's Authorized Site, online access to ASTM's journal for which the Subscriber maintains a current subscription to the print or online version.

To do so, ASTM will engage an independent consultant, subject to a confidentiality agreement, to review your use of ASTM Documents. You agree to permit access to your information and computer systems for this purpose. Verification will take place upon no less than 15 days notice, during normal business hours and in a manner that does not interfere unreasonably with your operations.

Definitions. For purposes of this License, an Authorized Site is a localized site (one geographical location) that is under a single administration at a single location. For a Subscriber with locations in more than one city, each city is considered to be a different site. For a Subscriber with multiple locations in the same city, each location is considered to be a different site. (If you are seeking online access for multiple sites, please contact Kathe Hooper, ASTM International, at email@example.com or phone: 610-832-9634). Authorized User means only the employees, faculty, staff, and students officially affiliated with the Subscriber at the Authorized Site, and persons with legal access to the library's collections and facilities at the Authorized Site, using an IP address within the range identified in the subscription. Authorized Users may be persons remote from the Subscriber's physical location whose access is administered from the Authorized Site, but not persons at remote sites or campuses with separate administrations. For example, an employee of the Subscriber may be considered to be an Authorized User when accessing the Subscriber's network from home or while traveling to another city; however, employees of a branch campus or facility in another city are not considered to be Authorized Users. Subscriber is the person or entity which has subscribed to the ASTM journal and agreed to the terms of this limited license.
