The purpose of this study was to examine athletic training students’ media consumption to advance our understanding of the role the media play in reported incidences of sport-related concussion (SRC) and chronic traumatic encephalopathy (CTE) in American football and how media coverage of those injuries may potentially influence public perception. Participants who consumed more hours of television per day were more likely to disagree with the statements that reporting on SRC has helped to accurately educate the public, H(2) = 11.06, p = .01, and that reporting on CTE has helped to accurately educate the public, H(2) = 8.67, p = .01. Respondents who consumed more hours of Internet per day were more likely to disagree with the statements that accurate terminology is used to report SRC, H(2) = 7.78, p = .02, and that reporting of SRCs has helped to accurately educate the public, H(2) = 8.27, p = .02.

To examine the effects of whole-body periodic acceleration (pGz) on exercise-induced-muscle-damage (EIMD) -related symptoms induced by unaccustomed eccentric arm exercise.
Seventeen active young men (23.4 ± 4.6 y) made 6 visits to the research facility over a 2-wk period. On day 1, subjects performed a 1-repetition-maximum (1RM) elbowflexion test and were randomly assigned to the pGz (n = 8) or control group (n = 9). Criterion measurements were taken on day 2, before and immediately after performance of the eccentric-exercise protocol (10 sets, 10 repetitions using 120% 1RM) and after the recovery period. During subsequent sessions (24, 48, 72, and 96 h) these data were collected before pGz or passive recovery. Measurements included isometric strength (maximal voluntary contraction [MVC]), blood markers (creatine kinase, myoglobin, IL-6, TNF-α, TBARS, PGF2α, protein carbonyls, uric acid, and nitrites), soreness, pain, circumference, and range of motion (ROM).
Significantly higher MVC values were seen for pGz throughout the recovery period. Within-group differences were seen in myoglobin, IL-6, IL-10, protein carbonyls, soreness, pain, circumference, and ROM showing small negative responses and rapid recovery for the pGz condition.
Our results demonstrate that pGz can be an effective tool for the reduction of EIMD and may contribute to the training-adaptation cycle by speeding up the recovery of the body due to its performance-loss-lessening effect.
