The construction of the competitive identity of the child that practices under 7 football
The increase in extracurricular activities such as football among schoolchildren has involved new ways of capitalizing on the learning that is promoted, with implications for their self esteem. The purpose of this study is to understand the implications for the young sportsman his participation in this framework, in which he assumes a specific role in the microsystem of the team, on the construction of their identity. An ethnographic case study design is applied through participant observation of 10 under'7 football teams during a school year and semi structured interviews with their teachers. The analysis of qualitative data shows that the role that players assume incipiently in their teams is oriented toward performance and it has implications on their self esteem. The expectations of the adult environment affect the way in which the personal success of each player is assessed according to their role. It is discussed the relevance of rethinking the way in which sports training practices are offered in school sports so that expectations converge with the particular potential of each child. Adult sensitization is indispensable.

The Effect of an Online Concussion Education Program on Knowledge Retention for High School Football Coaches
A quasi experimental repeated measure design was used to investigate the effect of an online concussion education program on the knowledge retention among 37 high school football coaches over a 15 week period and whether any variables can successfully predict knowledge retention. Data were collected immediately following an online concussion education program and post 15 weeks using a valid and reliable concussion assessment tool consisting of three distinct subsections: signs and symptoms recognition, common concussion misconceptions, and scenario based question. A 2 tailed dependent samples t test was conducted to test knowledge retention, while a multiple linear regression analysis was performed to assess which coaching characteristics and school attributes affect knowledge retention. Results indicated that the high school football coaches had significantly lower overall as well as signs and symptoms subsection scores on 15 week follow up assessments compared to post course assessments, but the participants did not have significantly lower misconception or scenario subsection scores. Coaches' age, experience, level of education, school size or access to a full time certified athletic trainer did not significantly influence knowledge retention in this study. This study confirms the need to continue to assess long term outcomes to assure knowledge retention in high school football coaches after online concussion education.

Incidence, Mechanisms, and Severity of Game Related High School Football Injuries Across Artificial Turf Systems of Various Infill Weights
Background: Artificial turf surfaces are developed to duplicate playing characteristics of natural grass. With the newer generations of sand and rubber infill systems, the infill is a common component that varies between fields and is a critical factor that could influence the player surface interaction. Because the influence of infill weight on sport trauma is unknown, this study quantified football trauma in high schools in the United States across artificial turf systems of various infill weights. Hypothesis: Athletes would not experience differences in game related injuries across artificial turf systems of various infill weights. Study Design: Cohort study; Level of evidence, 2. Methods: Artificial turf systems were divided into 4 sand/rubber infill weight groups by pounds per square foot: =9.0, 6.0 8.9, 3.0 5.9, and 0.0 2.9. A total of 57 high schools in 4 states participated over the course of 5 seasons. Outcomes of interest included injury severity, as a function of infill weight, across head, knee, and shoulder traumas; injury category; primary type of injury; tissue type; specific body location of injury; cleat design; environmental factors; and turf age. Data were subject to multivariate analyses of variance (MANOVAs) and Wilks l criteria through use of general linear model procedures. Results: Of 1837 games documented, 528 games were played on infill weights of =9.0 lb/ft2, 521 on 6.0 8.9 lb/ft2, 525 on 3.0 5.9 lb/ft2, and 263 on 0.0 2.9 lb/ft2, with 4655 total injuries reported. MANOVAs indicated significant infill weight effects across injury severity (F 2,4648 5.087; P .0001) with significant main effects also observed by injury category, tissue injured, lower extremity joint and muscle, cleat design, environmental factors, and turf age. Post hoc analyses indicated significantly lower (P .05 to .0001) total and substantial traumas, concussions, shoe surface interaction during contact trauma, surface impacts, muscle tendon overload, cleat design influence, adverse weather trauma, lower extremity injuries, and turf age effect while athletes were competing on the 6.0 to =9.0 lb/ft2 infill weight systems compared with the lighter infill weight systems. Conclusion: As infill surface weight decreased, football trauma significantly increased across numerous playing conditions. Based on findings, high school football fields should minimally contain 6.0 pounds of infill per square foot.

Elevated markers of brain injury as a result of clinically asymptomatic high acceleration head impacts in high school football athletes.
OBJECTIVEThis prospective observational cohort study of high school football athletes was performed to determine if high acceleration head impacts (HHIs) that do not result in clinically diagnosed concussion still lead to increases in serum levels of biomarkers indicating traumatic brain injury (TBI) in asymptomatic athletes and to determine the longitudinal profile of these biomarkers over the course of the football season.METHODSSixteen varsity high school football athletes underwent baseline neurocognitive testing and blood sampling for the biomarkers tau, ubiquitin C terminal hydrolase L1 (UCH L1) neurofilament light protein (NF L) glial fibrillary acidic protein (GFAP) and spectrin breakdown products (SBDPs) All athletes wore helmet based accelerometers to measure and record head impact data during all practices and games. At various time points during the season, 6 of these athletes met the criteria for HHI (linear acceleration 95g and rotational acceleration 3760 rad/sec2) in these athletes a second blood sample was drawn at the end of the athletic event during which the HHI occurred. Five athletes who did not meet the criteria for HHI underwent repeat blood sampling following the final game of the season. In a separate analysis, all athletes who did not receive a diagnosis of concussion during the season (n 12) underwent repeat neurocognitive testing and blood sampling after the end of the season.RESULTSTotal tau levels increased 492.6% 109.8% from baseline to postsession values in athletes who received an HHI, compared with 164% 35% in athletes who did not receive an HHI (p 0.03) Similarly, UCH L1 levels increased 738.2% 163.3% in athletes following an HHI, compared with 237.7% 71.9% in athletes in whom there was no HHI (p 0.03) At the end of the season, researchers found that tau levels had increased 0.6 0.2 pg/ml (p 0.003) and UCH L1 levels had increased 144.3 56 pg/ml (p 0.002) No significant elevations in serum NF L, GFAP, or SBDPs were seen between baseline and end of athletic event or end of season sampling (for all, p 0.05).CONCLUSIONSIn this pilot study on asymptomatic football athletes, an HHI was associated with increased markers of neuronal (UCH L1) and axonal (tau) injury when compared with values in control athletes. These same markers were also increased in nonconcussed athletes following the football season.

White matter alterations over the course of two consecutive high school football seasons and the effect of a jugular compression collar: A preliminary longitudinal diffusion tensor imaging study
The cumulative effects of repetitive subclinical head impacts during sports may result in chronic white matter (WM) changes and possibly, neurodegenerative sequelae. In this pilot study, we investigated the longitudinal WM changes over the course of two consecutive high school football seasons and explored the long term effects of a jugular vein compression collar on these WM alterations. Diffusion tensor imaging data were prospectively collected both pre and postseason in the two consecutive seasons. Participants were assigned into either collar or noncollar groups. Tract based spatial statistics (TBSS) approach and region of interest based approach were used to quantify changes in WM diffusion properties. Despite comparable exposure to repetitive head impacts, significant reductions in mean, axial, and/or radial diffusivity were identified in Season 1 in multiple WM regions in the noncollar group but not in the collar group. After an 8 to 9 month long off season, these changes observed in the noncollar group partially and significantly reversed but also remained significantly different from the baseline. In Season 2, trend level WM alterations in the noncollar group were found but located in spatially different regions than Season 1. Last, the WM integrity in the collar group remained unchanged throughout the four time points. In conclusion, we quantitatively assessed the WM structural changes and partial reversal over the course of two consecutive high school football seasons. In addition, the mitigated WM alterations in athletes in the collar group might indicate potential effect of the collar in ameliorating the changes against repetitive head impacts.
