Athletic trainers, team physicians, and surgeons responsible for managing athletes with cerebral concussion must be equipped to properly identify, classify, and manage the injury. This seemingly simple task can create one of the greatest challenges facing sports medicine clinicians. Sport-related concussion has received significant attention in both the lay media and medical literature. Media attention surrounding multiple injuries to several high-profile athletes, some of whom were forced into retirement because of repeated concussion, has helped created a welcome awareness among sports medicine personnel and the public. As a result, clinicians, coaches, parents, and athletes at all levels of competition are becoming educated regarding the necessity to treat concussion seriously. In time, this will help create a safer playing environment for athletes at all levels of competition.

Sport related concussion has received considerable attention in both the lay media and medical literature in recent years. As a result, clinicians, coaches, parents, and athletes at all levels of competition are becoming educated about the necessity to treat concussions seriously. In time, this will help to create a safer playing environment for athletes at all levels of competition. Despite an array of complexities associated with studying sport related concussion, new scientific research and clinically based literature have provided sports medicine professions with a wealth of updated information on the treatment of sport related concussion.

There is an absence of literature pertaining to the reliability of core muscular endurance tests. The purpose of this study was to assess the test-retest and interrater reliability of four core muscular endurance tests. Participants were physically active, college students. Data were gathered during three trials for each core test. Participants were timed by two test administrators (raters) until the participant could no longer hold the test position. Test-retest reliability values ranged from 0.57–0.85 for all three trials, and from 0.80–0.89 for the latter two trials. Interrater reliability values ranged from 0.99–1.00 for all three trials of all four tests. Although the participants were not athletes, we were able to demonstrate good test-retest and interrater reliability for the core muscular endurance tests assessed.
