The present investigation was carried out to examine the incidence and pattern of injuries in adolescent multisport athletes from youth sports academy. Injury data were prospectively collected from 166 athletes during the seasons from 2009 to 2014. A total of 643 injuries were identified, 559 (87.0%) were time-loss injuries. The overall injury incidence was 5.5 (95% confidence interval CI: 5.1–6.0), the incidence of time-loss injuries was 4.8 (95% CI: 4.4–5.2), the incidence of growth conditions was 1.2 (95% CI: 1.0–1.4) and incidence of serious injuries was 0.6 (95% CI: 0.5–0.8) per 1000?h of exposure. The prevalence of overuse injuries was 50.3%. Growth conditions represented 20.0%. Most of the injuries (67.0%) involved the lower extremities, and both foot and ankle were the most predominant injured body parts (22.0%). Knee injuries were mostly from overuse (50 vs. 23, p?=?.02), whereas foot and ankle injuries resulted from an acute mechanism (94 vs. 31, p?<?.0001). Minor and moderate injuries accounted for 87.0%. Muscle, tendon and osteochondrosis injuries accounted for 52.0% of all injuries. Comparing groups, squash sport was having the highest injury incidence (8.5 injuries per athlete). Higher exposure was associated with greater overuse relative risk (RR?=?1.03, 95% CI: 1.01–1.014, p?<?.001). In conclusion, the results of this study identified a high incidence of injuries in this youth sports population. Striking was the prevalence of overuse injuries of 50%, which suggests the need for injury prevention protocols for adolescent highly trained athletes.  相似文献   

Symptoms of common mental disorders and related stressors in Danish professional football and handball     

Özgür Kilic  Haruhito Aoki  Rasmus Haagensen  Claus Jensen  Urban Johnson  Gino M. M. J. Kerkhoffs 《European Journal of Sport Science》2017,17(10):1328-1334

The aim of the study was twofold, namely (i) to determine the prevalence of symptoms of common mental disorders (CMDs) among current and retired professional football and handball players and (ii) to explore the relationship of psychosocial stressors with the outcome measures under study. A total of 1155 players were enrolled in an observational study based on a cross-sectional design. Questionnaires based on validated scales were set up and distributed among current and retired professional football and handball players by the Danish football and handball players’ union. In professional football, the highest prevalence (4 weeks) of symptoms of CMDs was 18% and 19% for anxiety/depression among current and retired players, respectively. In professional handball, the highest prevalence (4 weeks) of symptoms of CMDs was 26% and 16% for anxiety/depression among current and retired players, respectively. For both the current and retired professional football and handball players, a higher number of severe injuries and recent adverse life events (LE) were related to the presence of symptoms of CMD. Players exposed to severe injuries and/or recent adverse LE were 20–50% times more likely to report symptoms of CMD. The results suggest that it is possible to recognize the population of professional athletes that are more likely to develop symptoms of CMD. This could create the opportunity to intervene preventively on athletes that suffered from severe injury and/or recent adverse LE that could lead to a faster and safer recovery and psychological readiness to return to play.  相似文献   

Hot-Heads,Gentlemen and the Liberties of Tradesmen     

Daniel Johnson 《Cultural and Social History》2013,10(3):343-364

Abstract

Over the summer and autumn of 1739 Philadelphia’s two newspapers published competing versions of a hearing in the Pennsylvania assembly that was described as the ‘Affair of the Tanners’. What began as a minor property dispute in the colonial assembly became, with the aid of the local press, a citywide paper war for the support of the urban populace. This article argues the affair provides unique evidence for competing conceptions of the common good in the eighteenth-century colonial city, and was an expression of conflict with deep roots in Philadelphia’s history. The affair also shows how the medium of print could reflect both transatlantic cultural processes as well as distinctly local grievances, as a group of prosperous city artisans and their opponents utilized the city’s newspapers to articulate competing commonwealth ideologies.  相似文献   

Towards a Cultural Understanding of the Disability and Deaf Experience: A Content Analysis of Introductory Multicultural Education Textbooks     

John R. Johnson  Jesús Nieto 《Multicultural Perspectives》2013,15(3):33-43

This paper reports the findings of a simple normative content analysis of 11 multicultural education textbooks to determine the extent to which disability and deaf culture are represented. In addition, this study examines multicultural education textbooks to assess the extent to which perspectives of members of the disability and deaf communities are represented in the discourse about disabled and deaf persons. Results indicate that on average less than 1% of the total pages of text reviewed addressed or mentioned disability or deaf culture. Of these, it was found that on average about 6% of the pages addressed disability or deaf culture. In addition, inaccurate information was presented and perspectives were often not informed by a substantial body of literature that has emerged in the field of disability studies. It was found that multicultural education textbooks rely heavily on information about persons with disabilities from Special Education that may not be widely accepted by disabled or deaf persons. A follow-up paper examines the implications of the exclusion of disabled and deaf persons and their perspectives from the discourse about the shared and collective disability and deaf experience in favor of a dominant perspective widely held by the nondisabled professional community. Questions are raised about whether this is consistent with the values and goals of multicultural education and teaching. A rationale and recommendations are proposed for engaging disabled and deaf persons about their shared and collective experience and for promoting cultural competence and proficiency with respect to the disability and Deaf experience in multicultural education.  相似文献   

Facilitating Intercultural Communication in Parent–Teacher Conferences: Lessons From Child Translators     

Inmaculada M. García–Sánchez  Marjorie Faulstich Orellana  Megan Hopkins 《Multicultural Perspectives》2013,15(3):148-154

In this article Abraham Lincoln is considered as an alternative to the usual type of patriot's hero. He reminds us of our great historical failings. He remains a figure of controversy, a national hero in only some corners of society. He is the heroic President who serves as the first compassionate defender of the downtrodden, and he is a hero in those subcultures as well. Lincoln's treatment in the movies is discussed, focusing particularly on the recent movie Lincoln. Lincoln is seen as a match for the usual movie hero. His famous immunity to casual treatment in popular culture is discussed as well.  相似文献
