高强度间歇训练(HIIT)是以≥无氧阈或最大乳酸稳态的负荷强度进行多次持续时间为几秒到几分钟的练习,并且每 2.次练习之间安排不足以使练习者完全恢复的静息或低强度练习的训练方法。进入2 1.世纪以来,HIIT受到了训练科学与实践领域的密切关注,越来越多的教练员在训练实践中开始采用HIIT来提升运动员的竞技表现。然而,HIIT不只是“高强度”和“间歇”这么简单,其效果和价值的发挥需要考虑诸多因素。本文基于《高强度间歇训练的科学与应用:训练安排的解决方案》一书内容,分别从形式和目标类型、应用的整体框架、应用情境、同期化训练、关键指标 5.个方面对HIIT进行了论述,旨在为教练员和科研人员在训练实践当中应用HIIT并发挥HIIT的价值提供参考 相似文献

The visual-motor integration of preschool children who varied in terms of race, sex, and socioeconomic status was assessed using the Beery-Buktenica Test of Visual-Motor Integration (VMI). An analysis of covariance revealed that there were significant main effects for race, sex, and socioeconomic status. Since, at the three- and four-year level, the VMI was normed only on white suburban children, the results of this study seemed to indicate the need for norms for black children at the preschool level. Thus, the second part of this paper reports normative data for black preschool children on the VMI. 相似文献

ABSTRACT Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school. 相似文献

Finding the common ground: Teachers' and employers' representations of English in an assessment context

There has been a long‐standing debate about how ‘English’ can be defined. Educational policy changes have typically been driven by differing representations of the subject, and have ranged from broad ‘aesthetic’ definitions to more narrow ‘functional’ views. The present study aims to analyse areas of consensus and contention in stakeholders' discourse regarding English. A questionnaire‐based survey and focus groups were used to explore how teachers and employers viewed English as a subject. Their views were conceptualised into three themes: the importance of functional English; English as atomistic versus holistic study; and English as critical thought. These themes are discussed in relation to historical definitions of ‘English’, and their implications for the future reform of English qualifications. 相似文献
