The founding of the Korean Women Taekwondo Federation means the fetal movement of women taekwondo in Korea and it can be said to have been quite significant in that it increased women's confidence in their statuses and activities in the environments of the times when women's social activities were increasing. The development of women taekwondo competitions began in earnest when the first women taekwondo hall in the world was opened as a result of passionate activities of early female taekwondo practitioners and the first taekwondo club was established in Ehwa Woman's University. Women's aspiration towards the challenge to the Olympic Games as well as international competitions is gradually increasing through the expansion of the base of women taekwondo. The status of women taekwondo in Korea that has been enhanced through challenges to various international competitions thus far beginning with the single taekwondo championship of foreigners in Korea in 1968 can be said to have contributed to the enhancement of the status of Korea as the birthplace of taekwondo and it is considered that women taekwondo could have continuously developed through diverse taekwondo championships by age held with women's steady effort and the expansion of the base of women taekwondo instructors.  相似文献

The Medical Library Association (MLA) appointed a Diversity and Inclusion Task Force (DITF) in 2017. Sandra G. Franklin, AHIP, FMLA, chaired the task force and guided initiatives. From 2017 to 2020, the task force completed a review of MLA defining documents—including the mission, vision, values, and code of ethics—resulting in language updates to these documents. As MLA transitioned through the communities process, the DITF contributed to the transition. Other recommended essential changes to MLA profiles to promote awareness included updating pronouns to promote gender inclusivity and suggestions for the Annual Meeting Innovation Task Force. DITF members actively brought diversity and inclusion programming and engagement to MLA members at annual meetings. The task force held a fish bowl conversation, an open forum, and a Diversity Dialogues roundtable discussion; provided interactive discussion boards; and designed an MLA diversity button. Beyond MLA annual meetings, the task force hosted two critical librarianship meetings and a Twitter chat to engage MLA members with diversity and inclusion topics. Task force members promoted diversity and inclusion beyond their task force appointments with presentations at chapter meetings and other non-DITF MLA annual meeting programming. A notable task force accomplishment included completing a survey of MLA members to gather baseline demographic characteristics, including never before collected data about disability, socioeconomics, and caregiver status. This report provides an overview of DITF activities from 2017 to 2020.  相似文献

Physiological requirements of cricket   总被引:1,自引:1,他引:0  
Despite its long history and global appeal, relatively little is known about the physiological and other requirements of cricket. It has been suggested that the physiological demands of cricket are relatively mild, except in fast bowlers during prolonged bowling spells in warm conditions. However, the physiological demands of cricket may be underestimated because of the intermittent nature of the activity and the generally inadequate understanding of the physiological demands of intermittent activity. Here, we review published studies of the physiology of cricket. We propose that no current model used to analyse the nature of exercise fatigue (i.e. the cardiovascular-anaerobic model, the energy supply-energy depletion model, the muscle power-muscle recruitment model) can adequately explain the fatigue experienced during cricket. A study of players in the South African national cricket team competing in the 1999 Cricket World Cup revealed that, in a variety of measures of explosive ('anaerobic') power and aerobic endurance capacity, they were as 'fit' as South African national rugby players competing in the 1999 Rugby World Cup. Yet, outwardly, the physiological demands of rugby would seem to be far greater than those of cricket. This poses the question: 'Why are these international cricketers so fit if the physiological demands of cricket are apparently so mild?' One possibility is that this specific group of athletes are unusually proficient in a variety of sports; many achieved high standards of performance in other sports, including rugby, before choosing to specialize in cricket. Hence their apparently high fitness may simply reflect a superior genetic physical endowment, necessary to achieve success in modern international sports, including cricket. Alternatively, it could be hypothesized that superior power and endurance fitness may be required to cope with the repeated eccentric muscle contractions required in turning and in bowling and which may account for fatigue and risk of injury in cricket. If this is the case, the fitness of cricketers may be increased and their risk of injury reduced by more specific eccentric exercise training programmes.  相似文献

The purpose of this study was to determine whether there are differences between racial groups for body mass, stature and body mass index (BMI) in South African elite U18 rugby players and whether there were significant changes in these measurements between 2002 and 2012. Self-reported body mass and stature were obtained from U18 players (n = 4007) who attended the national tournament during this period. BMI was calculated for each player.White players were 9.8 kg heavier than black players, who were 2.3 kg heavier than coloured players (P < 0.0001). The body mass of all groups increased from 2002 to 2012 (P < 0.0001). White players were 7.0 cm taller than black players who were 0.5 cm taller than coloured players (P < 0.0001). Players’ stature measurements did not change significantly during the study period. The average BMI of white players was 0.9 kg·m?2 greater than black players who were on average 0.7 kg·m?2 greater than coloured players (P < 0.0001). The BMI of all groups changed similarly over the study period. The body mass, stature and BMI of elite under-18 rugby players in South Africa were significantly different between racial groups. This has implications for transforming the game to make it representative of the South African population.  相似文献
