Practical, running-based treadmill tests of anaerobic capacity are needed and welcome, as long as they are validated against appropriate running performance. It is fundamentally wrong to validate them against the cycling-based Wingate Anaerobic test regardless of its proven validity and reliability. 相似文献

OBJECTIVE: Most research in child maltreatment within family focuses mainly on the pathological damage caused to the battered child. This study, based on a salutogenic approach, focuses on the resources that may help maltreated children to cope with their state and stay well. METHOD: Resilience was measured by two variables: perceived competence and psychological distress. The moderating or buffering variables that may contribute to better coping were: sense of family coherence, psychological sense of school membership, and social support. Two hundred and twenty-six 8th graders answered an anonymous self-report inventory. Based on the students' answers, they were divided into two groups: those who reported that they had been maltreated (MC) (n = 81) and those who did not (NMC) (n = 145). RESULTS: The study revealed a significantly high percentage of adolescents (35.6%) who reported having been maltreated within their families. A significant difference was found between the MC and the NMC in levels of perceived competence (higher for the NMC) and psychological distress (higher for the MC group). The moderating variables were found to have a differential effect on the dependent variables within the two groups. Sense of family coherence was found to be the main contributor to variance explanation of perceived competence among the MC, while sense of school membership had the main effect among NMC. CONCLUSIONS: The findings support a salutogenic approach in studying maltreated children. Implications on the possible detection of maltreated children in the community and on their coping resources that may contribute to resilience are discussed. 相似文献

Musta?rib is a term that refers to the local Arabic-speaking Jews in Syria, Palestine and Egypt. The article discusses the Musta?rib community of Cairo in the late sixteenth century. Like other Medieval Jewish communities, the Musta?rib of Cairo had an advanced system for support of the needy. It included regular support for the poor, for widows and orphans, and occasional help for foreign travellers, captives, and more. Based on Genizah documents in Judaeo-Arabic, the article discusses the mechanism of welfare in that community and proves the influence of European Jewish immigrants on the construction of this system.The Musta?ribs are romanticised in classic Zionist historiography as deeply rooted farmers. The article argues that the Musta?ribs were first and foremost members of an urban population. It also suggests that contrary to the classic image of them as a fixed and unchanging population, which resided in the same area for successive generations, the Musta?rib society should be viewed as a society in motion. They adjusted to historical changes, were influenced by other Jewish cultures, and applied changes to improve their welfare system. 相似文献

In response to Armstrong’s recent Special Topics review of “Top 10 Research Questions Related to Youth Aerobic Fitness,” this commentary revisits some of the points raised, particularly in relation to the question of whether a child?adult trainability difference does indeed exist. Discussed are the validity of much of the existing pediatric maximal oxygen consumption data upon which trainability conclusions are drawn, why differential trainability is likely a fact rather than a doubt, a reasoned novel approach to explaining the phenomenon, and how that explanation can bear upon and answer several of the other raised questions. The commentary is intended to inspire and encourage fresh thinking not only in relation to pediatric aerobic trainability, but more generally, regarding pediatric exercise physiology and performance and how they differ from those of adults. 相似文献

针对Armstrong最近关于“与青少年有氧能力相关的10个问题”的专题评论,再次对其提出的一些观点进行回顾,特别是儿童——成年人之间可训练差异性是否存在的问题。讨论了许多现有的可得出可训练性结论的儿童VO2max数据的有效性,为什么可训练性差异可能是一个事实而不是疑问,为解释这一现象所提供的一种合理的新方法,以及这种解释可以如何承担和回答其他几个提出的问题。本评论旨在激励并鼓励新的想法并提出建议,把注意力放在儿童的有氧可训练性上,还要更多地关注儿童运动生理学和表现以及他们与成年人的不同之处。 相似文献
