Ethnic identity and the daily psychological well-being of adolescents from Mexican and Chinese backgrounds

Protective effects of ethnic identity on daily psychological well-being were examined in a sample of 415 ninth graders from Mexican and Chinese backgrounds. Utilizing daily diary assessments and multilevel modeling, adolescents with a greater regard for their ethnic group exhibited greater levels of daily happiness and less daily anxiety averaged over the 2-week study period. Ethnic regard moderated the daily association between normative stressful demands and happiness, and between stressful demands and happiness experienced 1 day after stressors occurred. Moderating effects were significant even after controlling for self-esteem. Although no buffering effects of ethnic centrality were found, the results point to the positive influence of ethnic regard in the daily lives of adolescents from ethnic minority backgrounds.     

The influence of hydration on anaerobic performance: a review

This review examines the influence of dehydration on muscular strength and endurance and on single and repeated anaerobic sprint bouts. Describing hydration effects on anaerobic performance is difficult because various exercise modes are dominated by anaerobic energy pathways, but still contain inherent physiological differences. The critical level of water deficit (approximately 3-4%; mode dependent) affecting anaerobic performance is larger than the deficit (approximately 2%) impairing endurance performance. A critical performance-duration component (> 30 s) may also exist. Moderate dehydration (approximately 3% body weight; precise threshold depends on work/recovery ratio) impairs repeated anaerobic bouts, which place an increased demand on aerobic metabolism. Interactions between dehydration level, dehydration mode, testing mode, performance duration, and work/recovery ratio during repeated bouts make the dehydration threshold influencing anaerobic performance mode dependent.     

我寻回了梦想的翅膀

我数月前结婚了,但我的丈夫——格鲁吉亚小镇的一位英姿魁梧的空军飞行员——并不知道我们怎么就相遇了。而且。他也不知道我是怎么接近他的。在他单膝下跪。拿着订婚戒指的那一刻。我还担心。告知生命中的挚爱,我们走在一起并不是命运。而是源自于我在全国寻找一个飞行员的结果。是否为时已晚。     

Altitude training in endurance running: perceptions of elite athletes and support staff

This study sought to establish perceptions of elite endurance athletes on the role and worth of altitude training. Elite British endurance runners were surveyed to identify the altitude and hypoxic training methods utilised, along with reasons for use, and any situational, cultural and behaviour factors influencing these. Prior to the 2012 Olympics Games, 39 athletes and 20 support staff (coaches/practitioners) completed an internet-based survey to establish differences between current practices and the accepted “best-practice”. Almost all of the athletes (98%) and support staff (95%) surveyed had utilised altitude and hypoxic training, or had advised it to athletes. 75% of athletes believed altitude and hypoxia to be a “very important” factor in their training regime, with 50% of support staff believing the same. Athletes and support staff were in agreement of the methods of altitude training utilised (i.e. 'hypoxic dose’ and strategy), with camps lasting 3–4 weeks at 1,500–2,500 m being the most popular. Athletes and support staff are utilising altitude and hypoxic training methods in a manner agreeing with research-based suggestions. The survey identified a number of specific challenges and priorities, which could provide scope to optimise future altitude training methods for endurance performance in these elite groups.     

Primary Teachers’ Recommendations for the Development of a Teacher-Oriented Movement Assessment Tool for 4–7 Years Children

To inform the development of a teacher-oriented movement assessment tool, this study aimed to explore primary school teachers’ perceptions of assessing fundamental movement skills (FMS) within Physical Education (PE) lessons. Thirty-nine primary school teachers of PE, located in the United Kingdom, participated in an individual or group in-depth interview. Findings signify that teachers perceive a need for a movement assessment tool that is simple for them to use, quick to administer and provides valuable feedback to guide future teaching and learning. This is vital as teachers indicated a lack of appropriate resources and a shortage of curriculum time restricts their use of assessment within PE. A movement assessment tool that was integrated on a digital technology platform could increase teachers’ understanding of assessing FMS and enhance children’s learning of FMS.
