国际奥委会决定于2014年在南京举办第二届青年奥林匹克运动会。这是一项非常重要的决定。应该抓住这个契机,大力促进我省学校体育、特别是儿童少年体育迈上新台阶。为此,本文提出系列建议。

论球场战斗力

钟文先生在《人民日报》慨叹"三大球的沉沦"。"三大球沉沦"的直接表现是球场战斗力软弱,深层原因是训练思路问题。球队实力并非束缚于固定因素,在一定的客观条件下,训练方法乃竞赛生死之间灵活转换的关键。

试论茅鹏“全周期理论”之“早期端”理论——兼论早期专项化训练

运动训练以生命为载体,生命全周期的存在决定了运动训练全周期的存在。在运动训练全周期中,其早期端对全周期的影响至关重要,甚至决定着全周期的整体性结果,而早期端运作的重要形式是早期专项化训练。本文结合自身实践对此理论进行了再认识,并分析了产生早期专项化训练误区的原因。

Parental perceptions of the effects of exercise on behavior in children and adolescents with ADHD

Background： Anecdotally, parents often report that children with attention deficit hyperactivity disorder （ADHD） who engage in regular physical activity （PA） experience positive behavioral changes. The purpose of this study was to examine this anecdotal relationship to provide preliminary evidence relevant to the potential benefits of PA on ADHD symptoms. Methods： Parents （n = 68） of children diagnosed with ADHD completed an lnternet survey assessing perceptions of how PA influences their child＇s symptoms. Results： A significantly greater percentage of parents reported that regular PA positively impacted symptoms. However, there were no uniform effects for all types of ADHD symptoms. The results indicate that there may be more positive benefits for symptoms of inattention and hyperactivity than for those of impulsivity. Conclusion： This is the first study to empirically document parents＇ perceptions of how PA influences ADHD and suggests that PA can be a viable strategy for reducing symptoms. PA may have greater benefits for specific symptoms of ADHD, providing critical information for developing PA interventions for children and adolescents.

Crohn’s and colitis in children and adolescents

Crohn＇s disease and ulcerative colitis can be grouped as the inflammatory bowel diseases （IBD）. These conditions have become increasingly common in recent years, including in children and young people. Although much is known about aspects of the pathogenesis of these diseases, the precise aetiology is not yet understood, and there remains no cure. Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life, including in infancy. Pain, diarrhoea and weight loss are typical symptoms of paediatric Crohn＇s disease whereas bloody diarrhoea is more typical of colitis in children. However, atypical symptoms may occur in both conditions： these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythma nodosum. Growth and nutrition are commonly compromised at diagnosis in both Crohn＇s disease and colitis. Consideration of possible IBD and completion of appropriate investigations are essential to ensure prompt diagnosis, the- reby avoiding the consequences of diagnostic delay. Patterns of disease including location and progression of IBD in childhood differ substantially from adult- onset disease. Various treatment options are available for children and adolescents with IBD. Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn＇s disease. Medical and surgical therapies need to considered within the context of a growing and developing child. The overall management of these chronic conditions in children should include multi-disciplinary expertise, with focus upon maintaining control of gut inflammation, optimising nutrition, growth and quality of life, whilst preventing disease or treatment-related complications.

Height centile curve for child and adolescents in Shaanxi province

Objective: It has been recommended that age-related centile curves of anthropometric indexes(such as height, weight) be used rountinly to evaluate the growth and development statues in children. Presented here is the age-related height centile curves for children aged 0-18 years in Shaanxi, China,1995. Methods: Data of the Shaanxi population were retrieved from The Third Nationwide Growth Survey to construct the age-related height centile curves. The LMS method was used for curve fitting; all analyses were carried out on the basis of different sexes through a special program for LMS(λ-median-coefficient) method which was devised by Cole TJ. Results: Centile curves for boys and girls, showing similar age-related features but girls'puberty coming two years earlier than boys'. The period of puberty growth increment was about 2 years longer for boys. At age 18, boys were taller than girls for about 14 cm. Compared with height standard of NCHS(national center of health statistics), Shaanxi children were taller than American children before 14 years for boys, 12 years for girls, but after 15 years for boys and 13 years for girls, Shaanxi children were shorter than American ones. At age 18, Shaanxi children was 5.6 cm for boys and 4.9 cm for girls shorter than NCHS. Shaanxi children's height increase range from 1958 to 1995 at the same age was 4.9-15.1 cm ,with the mean of 9.59 cm for boys, and 3.7-12.5 cm, with the mean of 8.38 cm for girls. Between 1958-1995, the increasing velocity every ten years were 2.57 cm for boys and 2.26 cm for girls, which indicated that the children have reached the optimum. Conclusion: By means of LMS method, we constructed age-related height centile curves for Shaanxi children aged 0-18 years, these height centile curves are the first one for the Chinese children. It can be used as a reference for assessing growth and development status of Shaanxi children aged 0-18 years.

Children and adolescents with Down syndrome,physical fitness and physical activity

Children(5-12 years) and adolescents(13-19 years) with Down syndrome(DS) possess a set of health,anatomical,physiological, cognitive,and psycho-social attributes predisposing them to limitations on their physical fitness and physical activity(PA) capacities.The paucity of studies and their conflicting findings prevent a clear understanding and/or substantiation of these limitations.The purpose of this article was to review the measurement,determinants and promotion of physical fitness and PA for youth(i.e.,children and adolescents) with DS. The existing body of research indicates that youth with DS:1) have low cardiovascular and muscular fitness/exercise capacity;2) demonstrate a greater prevalence of overweight and obesity;3) a large proportion do not meet the recommended amount of daily aerobic activity;and 4) their PA likely declines through childhood and into adolescence.Future research should focus on:1) strength testing and training protocols;2) methodologies to determine PA levels;and 3) practical interventions to increase PA.

Henriksen and Flora （1999） Revisited A Literature Review on Third-Person Effects and Children/Adolescents＊

In this literature review on TPE （third-person effects） and the behavioral consequences on children, the research questions posed are how the body of knowledge has evolved since the first empirical evidence of TPE among children and what knowledge gaps that remain. The traceable developments are two： （1） Compared to the vast amount of articles on TPE in general, the 5 9 identified on the topic of children are few and two thirds actually focus on adolescents/young adults rather than children. The reason put forward for studying younger children is the urge to prevent risky behavior through media literacy programs or pro-social advertisements; and （2） The studies have not primarily addressed results to support occurrence of TPE among children. Rather they support parental TPE or among the adolescents that TPE and reverse TPE occur due to certain kind of media content. The discussion on knowledge gaps that remain follow three themes： （1） Differentiations between self and others are in psychological studies implied to occur among children between the ages of 3-4 years old, yet no study address how children develop TPE; （2） There is a tendency to follow the more general development within TPE research with the renewed interest in behavioral consequences. But the primary behavioral consequence studied in TPE in general and within studies of TPE and children is support for censorship. Few studies address ＂real＂ behavioral consequences like parental mediation; and （3） There is also a need for more theoretically coherent research on the importance of social distance.

Young people are fit and active——Fact or fiction?

This paper analyses young people's habitual physical activity(HPA) and aerobic fitness(AF) in relation to health and well-being,with reference to previous generations.Data consistently show that more boys than girls experience health-related physical activity(PA) and that both genders experience a decline in HPA during adolescence.The majority of young people(～60%-75%) do not meet the requirements of current health-related PA guidelines but youth HPA appears to have stabilised over the last two decades.Although it does not describe all aspects of AF, peak oxygen uptake(peak VO_2) is recognised as the best single measure of AF.Peak VO_2 is enhanced with age,growth and maturation with increases of～150%and～80%in boys and girls respectively from 8 to 16 years.Boys' values are higher than those of girls throughout childhood and adolescence with the gender difference reaching～35% by age 16 years.There is no compelling evidence to suggest that young people have low levels of peak VO_2 or that they are less aerobically fit than children of previous generations.Despite the relative stability of peak VO_2 there has been a decline of～13%over the last 35 years in young people's ability to perform maximal aerobic exercise which involves the transport of body mass.In their daily lives young people very rarely experience PA of the intensity and duration to enhance AF and peak VO_2 is, at best,only weakly related to current levels of HPA during youth.Low levels of HPA and a marked secular decline in maximal aerobic performance remain major issues in the promotion of youth health and well-being.

The Theory and Practice of Multicultural Education for Young Children by Means of Art Teaching Within the Artistic Education Classes

Due to the fast development of the Internet and other modern communication, people now interact easier than ever beyond the national boundaries and live in a global village. In the era of globalization, multicultural education has been important for all people around the world ever since their early childhood. Art is a necessary approach for young children to learn the world and expand their vision. It is also a good path for young children to learn different cultures, to foster respect for them, to enjoy cultures different from themselves, and to improve their skills for interacting with people from other cultural backgrounds. The main purposes of this article are to discuss the reason why art can be a potential approach to learning multi-cultural education and how an art approach can nourish young children＇s multi-cultural equipment. To reach these two purposes, literature review and case study analysis are adopted. There are five sections in this article. The first section introduces the background of this study. The second section explores the relation between art and multi-culture. The third section discusses how to use art in an antibias way and respect different cultures for young children. The fourth section analyzes two cases in order to know how to design curriculum, practice teaching and evaluate the efforts of multicultural education. The finally section is about the conclusion and some suggestions.

The Lifeline for Suicide Prevention of Children and Teenagers in Bucharest, Romania

Suicide is one of the leading causes of teenagers＇ deaths. Even whether it is preventable, most of the time, there are still very few projects or actions of the local authorities and/or organisations in Romania, due to the lack of information and resources. The suicide prevention line for children and teenagers in Bucharest is presented and evaluated after five years of activity. It may be considered as one example of good practice, since it managed to put together local knowledge, human resources, and social actors. The suicide prevention line for children and teenagers in Bucharest has been established in 2009 by the General Directorate of Social Welfare of Bucharest Municipality, in partnership with the Psychiatric Hospital ＂Prof. dr. Alexandru Obregia＂. The finances are provided by the Welfare Department, the location belongs to the Psychiatric Hospital, and the mental health services are coordinated by a neuro-psychiatrist. There are about 30 volunteers taking the phone calls 24/7. Since 2011, they established the Association of Suicidology.

Dopamine receptor D2 polymorphism is associated with alleviation of obesity after 8-year follow-up: a retrospective cohort study in obese Chinese children and adolescents

Objective： The aim of this study was to explore the association of dopamine receptor D2 （DRD2） polymorphism and alleviation of obesity in children and adolescents after 8-year follow-up. Methods： This retrospective cohort study included obese children and adolescents with a follow-up period of 8 years. Baseline clinical character- istics and DRD2 polymorphisms （including rs1076562, rs2075654, and rs4586205） were extracted from medical records. A follow-up visit was performed in May 2017 to collect related data including height, weight, diet compliance, and exercise compliance. Results： One hundred and nine obese children and adolescents were included in the current study. Among three DRD2 single nucleotide polymorphisms, only rs2075654 had a statistically significant association with alleviation of obesity, as the alleviation rate for minor allele carders （68.6% for TC＋TT） was higher compared to the major allele homozygote （43.3% for CC）. After adjusting for all related factors, the hazard ratio of rs2075654 minor allele carders for the alleviation of obesity was 3.34 （95% confidence interval （CI）： 1.30-8.58）. Conclusions： The rs2075654 ~olvmomhism of DRD2 is related to Ionq-term obesity alleviation in obese Chinese children and adolescents.
