To examine the utility of neuropsychological tests in assessing college athletes prior to and following a sports-related mild Traumatic Brain Injury (mTBI). ⋯ Neuropsychological tests are useful in the detection of cognitive impairment following mTBI. The test data appear to be more effective than subjective report of symptoms in differentiating between injured and noninjured athletes at 48 hours postinjury. Although significant individual variability existed, most injured athletes recovered within 1 week of injury. A battery of tests, rather than any single test, is necessary to capture the variability that exists among injured athletes.

There have been no large studies of middle school students to assess the association between team sports participation and risk-taking behaviors, despite evidence in high school and collegiate athletes. Our study evaluated whether team sports participation is associated with specific risk-taking behaviors among a biracial middle school population. ⋯ Among a biracial middle school population, sports participants were more likely to demonstrate certain risk-taking behaviors when compared with non-sports participants. Further research is necessary to understand the relationships between risk-taking behaviors and team sports participation.

Randomized Controlled Trial Comparative Study Clinical Trial
The efficacy of Farabloc, an electromagnetic shield, in attenuating delayed-onset muscle soreness.
To assess the hypothesis that Farabloc, a fabric with electromagnetic shielding properties, would attenuate the symptoms, signs, and muscular strength deficit secondary to delayed-onset muscle soreness (DOMS) induced by two exposures to eccentric exercise in humans. ⋯ The data indicate that double layers of Farabloc fabric wrapped around the thigh reduces pain and strength loss and serum levels of malondialdehyde, creatine phosphokinase, myoglobin, leukocytes, and neutrophils when untrained human subjects are exposed to eccentric exercise to produce DOMS in the quadriceps. Farabloc shields high-frequency electromagnetic fields, although the results do not indicate how these changes are mediated. Further research is needed to determine the mechanism.

To examine the incidence and characteristics of concussions for one season in the Canadian Football League (CFL). ⋯ Many players experienced a concussion during the 1997 CFL season, but the majority of these players may not have recognized that fact. Players need to be better informed about the symptoms and effects of concussions.
