The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study. To identify the optimal body size and body composition components associated with 100-m backstroke speed performance, we adopted a multiplicative allometric log-linear regression model, which was refined using backward elimination. The multiplicative allometric model exploring the association between 100-m backstroke mean speed performance and the different somatic measurements estimated that biological age, sitting height, leg length for the lower-limbs, and two girths (forearm and arm relaxed girth) are the key predictors. Stature and body mass did not contribute to the model, suggesting that the advantage of longer levers was limb-specific rather than a general whole-body advantage. In fact, it is only by adopting multiplicative allometric models that the abovementioned ratios could have been derived. These findings highlighted the importance of considering somatic characteristics of young backstroke swimmers and can help swimming coaches to classify their swimmers and enable them to suggest what might be the swimmers’ most appropriate stroke (talent identification).  相似文献   

Sex differences in elbow and wrist joint loading during the cartwheel and round off with different hand positions performed by young gymnasts

The aim of the study was to determine if sex differences exist in the key elbow and wrist joint injury risk factors during different cartwheel (CW) and round-off (RO) techniques performed by young male and female artistic gymnasts. Sixteen active young gymnasts (8 males and 8 females) performed 30 successful trials of CW and RO with three different hand positions (parallel (10), T-shape (10) and reverse (10)). Synchronised kinematic and kinetic data were collected for each trial. Two-way repeated measures ANOVA (3 × 2, technique × sex) and effect-sizes (ES) were used for statistical analysis. In conclusion, female gymnasts exhibited greater normalised peak vertical ground reaction forces (VGRF), elbow and wrist compression forces and elbow internal adduction moments during CW and RO skills compared with male gymnasts. In both sexes, the parallel and reverse techniques increased peak VGRF, elbow and wrist compression forces and the elbow internal adduction moment. Increased elbow flexion resulted in decreased peak VGRF, elbow compression forces and elbow internal adduction moment. Injury risk factors including elbow extension and internal adduction moment with axial compression force suggest that a CW and RO in reverse and parallel techniques can be hazardous especially for young female gymnasts.  相似文献   

Gender equality in the Olympic Movement: not a simple question,not a simple answer     

Alexandra Avena Koenigsberger 《体育哲学杂志》2017,44(3):329-341

This article explores the strategies followed by the International Olympic Committee for the achievement of gender equality. It is argued that this international body can go beyond simply adopting an equality of opportunities approach to gender equality. It suggests which other strategies can be incorporated for which it draws on the different ways of understanding gender equality in gender political theory.  相似文献   

‘The Master is the Mistress’: women and fox hunting as sports coaching in Britain     

Erica Munkwitz 《Sport in History》2017,37(4):395-422

This paper explores the relationship between equestrianism and sport coaching at the turn of the twentieth century. Women were avid and admired participants in fox hunting and other mounted field sports by the mid-nineteenth century, and they expanded on this success by attaining positions of leadership in many hunts throughout Britain, specifically as Masters of Hounds. Women thus attained positions of supreme authority over, and therefore equality with, peers of both sexes well before they obtained wartime jobs after 1914 or achieved the vote in 1918. As Masters, women were teachers, trainers, mentors, managers and bosses; they were some of the first female sport coaches, advancing and revolutionising sport in a variety of ways, though such participation has yet to be fully studied or recognised. By examining the position of Master of Hounds and women’s involvement in these leadership roles, we can see how advances in sport shaped changes in social, cultural, and gender perceptions before and after the First World War.  相似文献   

Three-Year Study of Students’ Attitudes Toward Physical Education: Grades 4–8     

Kevin Mercier  Corinne Donovan  Anne Gibbone  Kimberly Rozga 《Research quarterly for exercise and sport》2017,88(3):307-315

Purpose: A relationship exists between attitudes toward physical education and future physical activity. The purpose of this study was to examine changes in attitude toward physical education as students progressed from upper elementary school (Grade 4) through middle school (Grade 8). Method: Three cohorts of students (Cohort 1, Grades 4–6, n = 96; Cohort 2, Grades 5–7, n = 71; and Cohort 3, Grades 6–8, n = 73) were each followed for 3 years to examine changes in attitudes toward physical education. Results: After an initial increase from Grade 4 to Grade 5, a significant decrease was observed from Grades 5 to 8 in students’ positive attitudes toward physical education, with a faster rate of change for girls than boys. Conclusion: This longitudinal study provides further insights regarding the attitudes of students as they progress from Grade 4 to Grade 8 and expands on previous findings identifying decreasing positive attitudes toward physical education as students age, particularly for girls. The results provide evidence to support targeted interventions.  相似文献

You Can Make the Difference: Women in Sport in Taiwan     

Chiung-Tzu Lucetta Tsai 《国际体育史杂志》2017,34(5-6):451-455

Abstract

This article aims to develop a comprehensive understanding of changing cultural norms that have enabled and constrained women’s sport activities. It aims moreover, to analyse the changing nature of women’s sport activities in Taiwan. I want to show that what men can do, what women can do – and what I want to, what I can, and what I will do. I also address how I became interested in sports history and the pursuits I have made in that field.  相似文献   

Modernising gender,civilising sex: perverse imaginary in the state feminist politics of Liu Yu‐hsiu     

Hans Tao‐Ming Huang 《Inter-Asia Cultural Studies》2013,14(4):540-558

Abstract

The gender sexual politics of Liu Yu‐hsiu has been pivotal in the hegemonic ascendancy of Taiwan state feminism in recent years. Through an examination of Liu’s psychoanalytically mediated essays of cultural criticism, this article traces the contour of Liu’s sexual imaginary within the context of 1990s feminist and queer politics. Liu’s modernising project of gender equality, I argue, upholds heterosexual monogamy as a feminist ideal that seeks to purge all the masculine ills, including perversion and promiscuity. Meanwhile, queers and prostitutes come to be figured as the very negativity that must be repressed. Yet, like the Lacanian Real, they impinge on the symbolic order that Liu ordains as they thwart her desire to civilise sex.  相似文献   

Heroes of Their Own Life Stories: Narrating the Female Self in the Feminist Age     

Lynn Abrams 《Cultural and Social History》2013,10(2):205-224

ABSTRACT

This article proposes a triple legacy of the expressive culture of the 1960s and 70s. Late twentieth century feminism, discourses of gender equality and the advent of modern confessional culture liberated women’s women’s voices, producing self-realising narratives and a shift in women’s facility to produce authentic ‘reflexive projects of the self’. Drawing on oral history interviews with women born in the 1940s in the United Kingdom, Australia and North America, a new concept for a distinct genre of women’s oral history narrative is advanced– the feminography – in which we hear women owning their voices and the stories those voices tell.  相似文献   

Desire: A History of European Sexuality. By Anna Clark/Sexuality in World History. By Peter N. Stearns     

《Cultural and Social History》2013,10(3):429-430

ABSTRACT

The present article uses Nell Dunn's Up the Junction (1963) to explore class, gender and the city in the 1960s. It focuses on three elements: the book's representation of post-war, urban working-class identity; the place of gender and sexuality within that representation; and, finally, Nell Dunn's own position as a middle-class observer. It argues for the continuing relevance and dynamism of class as a social referent in post-war, ‘affluent’ Britain. The article also explores the meaning of ‘slumming’ in the context of the mid-twentiethcentury city, against the background of ‘affluence’ and the emergence of the ‘permissive society’. What becomes particularly apparent in both contexts is the importance of femininity and female sexuality in the representation of mid-twentieth-century London, whether in terms of the portrayal of working-class women or the position of the middle-class author.  相似文献
