The neural bases of vitality forms     

Giuseppe Di Cesare  Marzio Gerbella  Giacomo Rizzolatti 《国家科学评论(英文版)》2020,7(1):202

Unlike emotions, which are short-lasting events accompanied by viscero-motor responses, vitality forms are continuous internal states that modulate the motor behaviors of individuals and are devoid of the autonomic modifications that characterize real emotions. Despite the importance of vitality forms in social life, only recently have neurophysiological studies been devoted to this issue. The first part of this review describes fMRI experiments, showing that the dorso-central insula is activated during the execution, the perception and the imagination of arm actions endowed with different vitality forms as well as during the hearing and the production of speech conveying vitality forms. In the second part, we address the means by which the dorso-central insula modulates the networks for controlling action execution and how the sensory and interoceptive information is conveyed to this insular sector. Finally, we present behavioral data showing the importance of vitality forms in social interactions.  相似文献   

"亚住高训"交替训练在中长跑运动员运动实践中的应用     

王迪  张小从  钱钰  谭泽芹  殷劲 《成都体育学院学报》2017,43(3)

通过"亚住高训"交替训练实验,对12分钟极限跑运动中动态心率、血氧饱和度、"极点"等指标进行研究,探讨"亚住高训"模式对"极点"等指标的影响及其提高中长跑运动员有氧工作能力及运动成绩的新途径.方法:对8名大学生中长跑运动员进行6周"亚住高训"实验研究.测试实验前、中、后期的12分钟极限跑、运动中心率、运动中血氧饱和度等指标,并根据运动生理学原理划分12分钟极限跑中机能变化相对应的"极点"等指标及其持续时间.结果:(1)"亚住高训"交替训练前、中、后,12分钟极限跑成绩、最大摄氧量、运动中心率及血氧饱和度等指标变化,呈现有利于有氧工作能力提高的趋势,部分指标存在显著性差异(P<0.05).(2)"亚住高训"实验后,运动员赛前训练12分钟极限跑的"极点"及其持续时间明显缩短、"第二次呼吸"时间延长、"终点冲刺"时间增加,部分指标存在显著性差异(P<0.05).结论:(1)"亚住高训"交替训练能有效提高运动员12分钟极限跑成绩,对运动员有氧工作能力有积极影响.(2)运动中通过心率、血氧饱和度实时检测,能够反映运动中"极点""第二次呼吸""终点冲刺"等指标的变化规律.(3)"亚住高训"交替训练能对12分钟极限跑过程中"极点""第二次呼吸""终点冲刺"及其持续时间的分配进行干预,有助于中长跑运动成绩的提高.  相似文献   

从美学角度浅析《枫桥夜泊》的英译     

樊迪 《海外英语》2013,(9)

随着跨文化交流的日益加深，大批的中内外学者展开了唐诗英译这一项工作。唐诗翻译不仅要建立在两种语言以及两种文化的对等关系上，更要在这种对等关系中寻求一种美的结合点，使得译文形神兼备。旨在从美学角度出发，浅析张继的《枫桥夜泊》的两个译本。  相似文献

Integrated reflectography and thermography for wooden paintings diagnostics     

Dario Ambrosini  Claudia Daffara  Roberta Di Biase  Domenica Paoletti  Luca Pezzati  Roberto Bellucci  Francesca Bettini 《Journal of Cultural Heritage》2010,11(2):196-204

The need of inspecting a masterpiece of fine art without affecting it led to develop non destructive methods of investigation. In the field of art conservation, several diagnostic techniques are being widely used to inspect works of art, giving different but complementary results. The present work deals with two of these methods, reflectography and thermography, both techniques examining objects in the infrared spectrum but in different wavelength bands. Their integrated data potentially provide a powerful tool for mapping hidden features and alterations of artworks. This was confirmed during the inspections of a 13th century panel painting under restoration at the Opificio delle Pietre Dure laboratories (Florence, Italy). A graphical user interface was also designed to aid operators in the field of conservation dealing with the results of the two IR methods. Many options such as image adjustment, comparison, overlaying and transparency variation, in addition to thermographic elaborations, have been made available to users. Imaging data integration provides a multi-layered and multi-spectral representation of the painting that yields a comprehensive diagnosis confirms the anomalies individuation and reduces the ambiguities of information coming from a single diagnostic method.  相似文献   

主导与主体的结合是当前体育教改的特点之一   总被引：1，自引：0，他引：1  

俞秀娣 《体育科研》1996,(3)

教师的主导作用与学生的主体作用是“教”与“学”的两个主要方面,教学过程中,教师在充分发挥主导作用的同时,应该考虑并积极引导学生“主体”作用的最大发挥,使“主导”促与“主体”紧密结合,才能有利于学生的身心发展与提高教学效果。  相似文献

Nutrition for the young athlete     

Meyer F  O'Connor H  Shirreffs SM;International Association of Athletics Federations 《Journal of sports sciences》2007,25(Z1):S73-S82

Athletics is a popular sport among young people. To maintain health and optimize growth and athletic performance, young athletes need to consume an appropriate diet. Unfortunately, the dietary intake of many young athletes follows population trends rather than public health or sports nutrition recommendations. To optimize performance in some disciplines, young athletes may strive to achieve a lower body weight or body fat content and this may increase their risk for delayed growth and maturation, amenorrhoea, reduced bone density, and eating disorders. Although many of the sports nutrition principles identified for adults are similar to those for young athletes, there are some important differences. These include a higher metabolic cost of locomotion and preferential fat oxidation in young athletes during exercise. Young athletes, particularity children, are at a thermoregulatory disadvantage due to a higher surface area to weight ratio, a slower acclimatization, and lower sweating rate. An appropriate dietary intake rather than use of supplements (except when clinically indicated) is recommended to ensure young athletes participate fully and safely in athletics.  相似文献
