1. 儿童青少年运动员应该食用多样化的食物,其中,蛋白质应占膳食总能量的12%-15%,碳水化合物至少占55%,而脂肪至多占30%。日常生活中如何吃才能满足这些要求呢?膳食指南宝塔提供了一条可行之道。2.有些营养素对热爱运动的儿童青少年运动员非常重要,要保证摄入充足,这些营养素是碳水化合物(包括纤维素)、维生素B6、维生素D、铁、钙、镁、锌、铬。科学合理、包罗各类食物的平衡膳食,对青少年运动员最大程度地全面摄取各种营养素,满足生长发育和运动训练的需要,是非常必要的。3.鼓励儿童青少年运动员在运动训练前、中、后进行补液,以避免脱水的发生。4.如果膳食合理平衡,就没必要额外补充营养品。 相似文献

This article explores how the library-student liaison program at Eastern Washington University (EWU) Libraries has evolved into an opportunity for students to develop leadership skills. Originally designed to foster better communication between the EWU Libraries and students enrolled at the university, we recognized that the process of achieving established goals for the program provided a vehicle for students' leadership-skill development. To facilitate the leadership process, librarians employed the Social Change Model. Designed specifically for college students, this model engages the student to develop individual capacities to strengthen group activities that foster positive changes in the community and society. 相似文献

The authors investigated C. E. Watkins's (1994) supervisor complexity model (SCM). The Psychotherapy Supervisor Development Scale (PSDS; C. E. Watkins, L. J. Schneider, J. Haynes, & R. Nieberding, 1995) was used to ascertain development over a 15‐week supervision practicum for 12 doctoral students and to compare their development with 7 doctoral students who had not yet begun their practicums. A set of retrospective interview questions produced responses that were used to investigate the viability of the 4 proposed discrete developmental stages in the SCM. The PSDS findings are congruent with theory. The retrospective interview findings, although interesting, are less definitive. Recommendations for research and training are presented. 相似文献

There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important. 相似文献
