Correlates of health in adolescent elite athletes and adolescents: A cross-sectional study of 1016 adolescents     

Philip von Rosen  Oskar Olofsson  Sebastian Väsbom  Annette Heijne 《European Journal of Sport Science》2019,19(5):707-716

The primary aim of this cross-sectional study was to compare subjective correlates of health, such as nutrition, self-esteem, sleep and stress, between adolescent elite athletes (n?=?625) and a reference group of adolescents (n?=?391) not involved in elite sports. A secondary aim was to study predictors for self-perceived stress. A questionnaire was e-mailed to all participants containing valid questions about competence-based self-esteem, nutrition, self-perceived stress and sleep. Our results show that adolescent elite athletes reported significantly (p?p?相似文献   

Actors who can’t play in the sports film: exploring the cinematic construction of sports performance     

Sebastian Byrne 《Sport in Society》2017,20(11):1565-1579

The sports film often focuses upon character psychology and narrative in the cinematic capturing and construction of sport and sports performance. However, the limited attention given to the role of the actor’s body threatens to compromise this seamless dramatic structure of the narrative, not to mention viewer identification with the protagonist, thus leading to inadequate sporting technique that fails to achieve verisimilitude. This paper looks to address the limitations in the actor’s bodily performance, by rethinking the relationship between the actor’s physical portrayal and their cinematic construction. I argue that cinematic techniques should function as an extension of the actor’s body, thus creating a more seamless fusion between the two. Adopting such a method would facilitate a more heightened representation of sports performance, while contributing to the unfolding of the plot through the bodily interactions between the actors during the spectacle of sports sequences.  相似文献   

Sport activities differentiating match-play improvement in elite youth footballers – a 2-year longitudinal study     

Arne Güllich  Peter Kovar  Sebastian Zart  Ansgar Reimann 《Journal of sports sciences》2017,35(3):207-215

This study examined contributions of different types of sport activities to the development of elite youth soccer performance. Match-play performance of 44 German male players was assessed by expert coaches twice, 24 months apart (age 11.1–13.1 years), based on videotaped 5v5 matches. Player pairs were matched by identical age and initial performance at t₁. Each player was assigned to a group of either “Strong” or “Weak Responders” based on a higher or lower subsequent performance improvement at t₂ within each pair (mean Δperformance 29% vs. 7%). A questionnaire recorded current and earlier amounts of organised practice/training and non-organised sporting play, in soccer and other sports, respectively. Group comparison revealed that “Strong Responders” accumulated more non-organised soccer play and organised practice/training in other sports, but not more organised soccer practice/training. Subsequent multivariate analyses (multiple linear regression analyses (MLR)) highlighted that higher resultant match-play performance at t₂ was accounted for R²_adj = 0.65 by performance at t₁, together with more non-organised soccer play and organised engagement in other sports, respectively, and greater current, but less earlier volume of organised soccer. The findings suggest that variable early sporting experience facilitates subsequent soccer performance development in German elite youth footballers.  相似文献

Dr. Howard A. Kelly's The Stereo Clinic: health science pedagogy and the egalitarian future of 3D clinical visualization     

Sebastian C. Galbo  Keith C. Mages 《Journal of the Medical Library Association》2022,110(2):258

This article situates emerging three-dimensional (3D) visualization technologies in the health sciences within the broader historical context of the stereoscope. Although 3D visualization technologies enhance pedagogy and deepen student engagement, they are generally cost-prohibitive and therefore inaccessible for many institutions. In light of this issue, the authors consider the work of American gynecologist and founding member of The Johns Hopkins Hospital in Baltimore, Maryland, Dr. Howard Atwood Kelly (1858–1943). A monumental work, Kelly''s The Stereo Clinic is a multivolume publication whose focal point was the stereoscope, an image-viewing device that can be seen as a prototype for present-day 3D technologies. Each installment presents a step-by-step overview of a specific surgical procedure using a didactic narrative and corresponding stereoscopic images that illustrate the clinical practices. Significantly, Kelly understood The Stereo Clinic as an egalitarian project that provided high-quality educational resources to students and practicing physicians who did not have access to world-class clinical suites and teaching institutions. Furthermore, he viewed The Stereo Clinic as a remedy to the commonplace frustrations of medical education, such as crowded surgical suites, and the hazards of in-person observation. The Stereo Clinic is an important case study because it reveals a medical profession at the turn of the twentieth century preoccupied with 3D visualization. Inventive clinicians such as Kelly did not only advocate for this technology on the strength of its pedagogical value; they also articulated the equalitarian nature of this medium and produced 3D technology accessible to a wide audience.  相似文献

The role of schools in bridging within-school achievement gaps based on socioeconomic status: a cross-national comparative study     

Haigen Huang  James Sebastian 《Compare》2015,45(4):501-525

Since the publication of the Coleman report in 1966, research on the role of schools in influencing student achievement relative to the role of family background has generated considerable interest and controversy. A large volume of international and comparative research has also been devoted to studying school effects on student achievement. Relatively few studies have examined international differences in the importance of schools in bridging achievement gaps based on socioeconomic status (SES). Using PISA 2012 data, this study examines the role of schools in bridging within-school SES gaps in achievement and compares findings across 61 countries. Contrary to prior research, we find that schools may have limited ability in bridging SES gaps that exist within schools. We also find that across all countries included in the study, specific factors such as the school’s learning environment and school context are not systematically associated with within-school SES gaps.  相似文献
