INTRODUCTION: Blood protein analysis of total tau (t-tau) may be a practical screening biomarker for chronic traumatic encephalopathy (CTE), a neurodegenerative tauopathy associated with repetitive head impact (RHI) exposure. We examined plasma t-tau in symptomatic former National Football League (NFL) players compared with controls and the relationship between RHI exposure and later-life plasma t-tau. METHODS: Ninety-six former NFL players (age 40-69) and 25 same-age controls underwent blood draw to determine plasma t-tau levels...

The authors present the development and laboratory system-level testing of an impact monitoring "Intelligent Mouthguard" intended to help with identification of potentially concussive head impacts and cumulative head impact dosage. The goal of Intelligent Mouthguard is to provide an indicator of potential concussion risk, and help caregiver identify athletes needing sideline concussion protocol testing. Intelligent Mouthguard may also help identify individuals who are at higher risk based on historical dosage...

BACKGROUND AND PURPOSE: Shoulder instability, a common issue among athletes who engage in contact sports, may lead to recurrent subluxations, or partial dislocations of the shoulder. Young athletic patients generally respond poorly to the nonsurgical treatments for shoulder instability that are commonly utilized. The purpose of this case report is to describe the effects of the treatment guided by the Mulligan Concept (MC) coupled with reflex neuromuscular stabilization (RNS) also known as reactive neuromuscular training (RNT), on an adolescent football player with glenohumeral joint (GHJ) instability who sustained a traumatic anterior subluxation...

OBJECTIVES: Researchers have argued that leadership is one of the most important determinants of team effectiveness. The present study examined the extent to which the perceived quality of athlete leadership was related to the effectiveness of elite sports teams. DESIGN: Three professional football teams (N=135) participated in our study during the preparation phase for the Australian 2016 season. METHODS: Players and coaching staff were asked to assess players' leadership quality in four leadership roles (as task, motivational, social, and external leader) via an online survey...

BACKGROUND: Lower extremity muscle injuries are common in professional football. Although less common than hamstring or quadriceps injuries in National Football League (NFL) athletes, calf injuries occur with relative frequency and have not previously been studied. PURPOSE: To evaluate gastrocnemius-soleus complex muscle injuries over the past 13 years from a single NFL team to determine the incidence of such injuries, their imaging characteristics, and return to play after such injuries and any correlation between imaging findings and prolonged return to play...

Objective This paper identifies general properties of language style in social media to help identify areas of need in disasters. Background In the search for metrics of need in social media data, much of the existing literature ignores processes of language usage. Psychological concepts, such as narrative breach, Gricean maxims, and lexical marking in cognition, may assist the recovery of disaster-relevant metrics from altered patterns of word prevalence. Method We analyzed several hundred thousand location-specific microblogs from Twitter for Hurricane Sandy, Oklahoma tornadoes, and the Boston Marathon bombing along with a fantasy football control corpus, examining the relative frequency of words in 36 antonym pairs...

BACKGROUND: A body of epidemiological studies has examined football injuries and associated risk factors among collegiate athletes. However, few existing studies specifically analyzed injury risk in terms of initial or subsequent injuries. PURPOSE: To determine athlete-exposures (AEs) and rates of initial and subsequent injury among collegiate football athletes. STUDY DESIGN: Descriptive epidemiological study. METHODS: Injury and exposure data collected from collegiate football players from two Division I universities (2007-2011) were analyzed...

PURPOSE: The determinants of areal bone mineral density (aBMD) and hip geometry estimates in adolescent athletes are poorly understood. This study aimed to identify the determinants of aBMD and hip geometry estimates in adolescent male athletes. METHODS: One hundred twenty one males (13.1±0.1 years) were measured: 41 swimmers, 37 footballers, 29 cyclists and 14 controls. Dual energy X-ray absorptiometry (DXA) measured aBMD at lumbar spine, femoral neck (FN) and total body...

BACKGROUND: Variations in ankle injury rates and distributions among competition levels are unclear, but such data may help inform strategies to prevent ankle sprains during American football. PURPOSE: To describe the epidemiological patterns of ankle sprains in youth, high school (HS), and collegiate American football. STUDY DESIGN: Descriptive epidemiological study. METHODS: Data regarding youth, HS, and college football athletes were collected from 3 injury surveillance programs: (1) the Youth Football Safety Study (YFSS), (2) the National Athletic Treatment, Injury and Outcomes Network (NATION), and (3) the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP)...

BACKGROUND: Previous research has described general injury patterns in community-level rugby union, but specific information on time-loss head injuries has not been reported. PURPOSE: To establish the incidence and nature of significant time-loss head injuries in English community rugby match play, and to identify the injury risk for specific contact events. STUDY DESIGN: Descriptive epidemiology study. METHODS: Over 6 seasons, injury information was collected from 46 (2009-2010), 67 (2010-2011), 76 (2011-2012), 50 (2012-2013), 67 (2013-2014), and 58 (2014-2015) English community rugby clubs (Rugby Football Union levels 3-9) over a total of 175,940 hours of player match exposure...

We develop and apply several novel methods quantifying dynamic multi-agent team interactions. These interactions are detected information-theoretically and captured in two ways: via (i) directed networks (interaction diagrams) representing significant coupled dynamics between pairs of agents, and (ii) state-space plots (coherence diagrams) showing coherent structures in Shannon information dynamics. This model-free analysis relates, on the one hand, the information transfer to responsiveness of the agents and the team, and, on the other hand, the information storage within the team to the team's rigidity and lack of tactical flexibility...

OBJECTIVES: To establish the position and duration-specific running demands of Australian Football (AF) competition for the prescription and monitoring of specific training drills. DESIGN: An observational time-motion analysis was performed on 40 professional AF players during 30 games throughout the 2014-15 competitive seasons. METHODS: Player movements were collected and peak values were calculated for moving averages of between 1-10min in duration for relative distance (mmin(-1)), high-speed relative distance (HSmmin(-1)), average acceleration/deceleration (ms(2)) and metabolic power (Pmet)...

Allergic rhinoconjunctivitis (AR/C), has been shown to impact upon athletic performance. The championships of the unique, amateur Irish sports of hurling and Gaelic football (collectively known as GAA) take place during the prime pollen months of summer. Elite GAA players must perform optimally when most exposed to pollen. Elite GAA subjects (n=254) underwent skin prick testing to 6 aeroallergens and completed a validated questionnaire (AQUA), producing a score indicating likelihood of having allergy. The prevalence of allergy (positive to at least one aeroallergen on SPT and positive AQUA score) was 27...

CONTEXT: Health care practitioners face increasing expectations to provide patient-centered care. Communication skills, specifically empathy, are critical in the provision of patient-centered care. Past work correlates empathy with improved patient satisfaction, compliance and treatment outcomes. In particular, a predictive relationship exists between clients' ratings of their clinician's empathy and treatment outcomes. There is a dearth of studies examining empathy using qualitative methodology and factors of empathy in athletic training...

CONTEXT: Injury risk factors and relevant assessments have been identified in women's soccer athletes. Other tests assess fitness, e.g. the Gauntlet Test (GT). However, little empirical support exists for the utility of the GT to predict time loss injury.
