"北风那个吹,雪花那个飘。"严寒的冬天来了,汤汁鼎沸的火锅让人心动,馋涎欲滴。火锅虽说一年四季都有,但吃火锅最佳的季节还是在冬季。窗外北风呼啸,大雪纷飞,一家人或亲朋好友围坐在火锅旁,新鲜的原料,丰富的品种,古朴的吃法,亲切的交谈,热闹的气氛,真是人间仙境。火锅,成为冬季人气最旺的美食。冬天吃火锅御寒又开胃,排除毒素祛风湿。色香味型麻辣鲜,款式多样营养全。微量元素易吸收,大众消费最实惠。简单方便宴亲朋,天伦之乐又美味。这首打油诗尽说的是冬天吃火锅的好处,其实,任何事情有利有弊,吃火锅虽然好处多,但也不像打油诗中所说的十全十美。如果吃法不科学、吃火锅也能给身体健康带来不利的因素,有的还能诱发出疾病。所以说吃火锅也要讲究科学,才能吃出营养和健康。 相似文献

1984年的初秋,芝加哥71街区的室外篮球场上,两个黑人高中生正在单挑。本基,你就让我赢一次吧,你现在简直和‘魔术师'一样厉害了。不对,你是会跳投的‘魔术师',如果你现在进入NBA,一定不会比那个叫迈克尔·乔丹的球员差。不行。尼克,你必须靠自己的能力战胜我。叫本基的少年左手一扬,又命中一记投篮,微笑着碎步后退。那好,我们再来……尼克边说边扑了上去。四年之后,尼克实现了NBA之梦,而本基,却早已经撒手人寰。尼克的全名是尼克·安德森,在NBA,这个名字是反派和愚蠢的代名词。1995年季后赛,安德森在短短一个月的时间里经历了从天堂到地狱,而他的职业生涯也在那时被定格。很少有人知道,安德森的人生并不平凡…… 相似文献

自然界中,一年分为春夏秋冬四季。在一个游泳爱好者看来,一年只有三季。一,冬泳。冬泳除了锻炼身体,更大的功能在于锻炼意志。如果说有兴趣和乐趣,那也是很少很少的。最多不过是心中有些自豪:我能冬泳,我很神气。二,夏泳。夏泳当然也锻炼身体,但它的成分里含有"沐浴、消暑、嬉戏"。炎炎夏日,静而有汗,泡在水里特别舒服。有那年轻的带了儿女,年老的带了孙孙,老少同游一江水,其乐无比。三,秋泳。更确切地说是下漂或横奔。古时西汉水,今日嘉陵江。名虽曰江,其实已蜕变为一条溪——水量太少。这河宽处不过百多米,窄处仅只三十米。稍微会两把水的,过河根本不 相似文献

采用文献资料法,从体育、运动和休闲等视角,对台湾地区休闲运动的概念表达和使用状况进行研究.发现:台湾地区的体育、运动和休闲概念的标识和使用经历着变化发展的过程.在今后的台湾地区相关概念使用中将延续如下发展趋势:行政机构和中小学用体育涵盖运动休闲;大学和学术研究中将运动、休闲和体育进行区分;新闻媒体和产业则偏向用休闲、运动取代体育. 相似文献

围绕高校武术教学的现状和改革,对河南省18所高校的1 336名学生和25名武术教师分别进行了问卷和走访调查。结果显示,武术是高校学生很感兴趣的教学项目,我们对此并没有重视,存在教学器材匮乏、教学内容陈旧等问题。其改革应从转变观念、改善课程结构、精选教材等方面进行。 相似文献

An important goal of the athlete's everyday diet is to provide the muscle with substrates to fuel the training programme that will achieve optimal adaptation for performance enhancements. In reviewing the scientific literature on post-exercise glycogen storage since 1991, the following guidelines for the training diet are proposed. Athletes should aim to achieve carbohydrate intakes to meet the fuel requirements of their training programme and to optimize restoration of muscle glycogen stores between workouts. General recommendations can be provided, preferably in terms of grams of carbohydrate per kilogram of the athlete's body mass, but should be fine-tuned with individual consideration of total energy needs, specific training needs and feedback from training performance. It is valuable to choose nutrient-rich carbohydrate foods and to add other foods to recovery meals and snacks to provide a good source of protein and other nutrients. These nutrients may assist in other recovery processes and, in the case of protein, may promote additional glycogen recovery when carbohydrate intake is suboptimal or when frequent snacking is not possible. When the period between exercise sessions is <8?h, the athlete should begin carbohydrate intake as soon as practical after the first workout to maximize the effective recovery time between sessions. There may be some advantages in meeting carbohydrate intake targets as a series of snacks during the early recovery phase, but during longer recovery periods (24?h) the athlete should organize the pattern and timing of carbohydrate-rich meals and snacks according to what is practical and comfortable for their individual situation. Carbohydrate-rich foods with a moderate to high glycaemic index provide a readily available source of carbohydrate for muscle glycogen synthesis, and should be the major carbohydrate choices in recovery meals. Although there is new interest in the recovery of intramuscular triglyceride stores between training sessions, there is no evidence that diets which are high in fat and restricted in carbohydrate enhance training. 相似文献

AbstractThe aim of the current inquiry was to identify the national origin of scholars who lead the work in the area of Sport and Exercise Psychology, and to examine whether their research output is connected to the Olympic success of their national athletes. Consequently, the two specialised journals with the highest impact factors in this field were examined for the origin of publications throughout 11 years for authors' national affiliations. Subsequently, the link between national research output and Olympic medals was examined. The results revealed that over 50% of the publications originate from Canada, the UK and the USA. National research output in Sport and Exercise Psychology was correlated with the number of Olympic medals; the proportion of shared variance was 42% and 57%, respectively, in the two journals. Nevertheless, it is posited that the observed link is primarily due to other factors that ought to be examined in future research. 相似文献

肌肉减少症又称肌少症(sarcopenia),是一种近来备受关注的老年综合征,泛指随着年龄的增长,人体出现肌量减少和肌力下降等改变。肌少症的特点是骨骼肌肌量减低并且肌肉内脂肪堆积,导致肌肉力量减低和肌肉功能下降,进而导致躯体残疾、生活质量降低,甚至死亡等。抗阻运动或称力量训练(strength training),是指肌肉主动收缩对抗阻力的一种运动形式,在通常情况下,这种运动的负荷远高于肌肉在有氧状态下的能力,具有强度大、持续时间短、力竭性等特征。肌肉是产生人体自主运动的动力源泉,而肌肉运动,特别是抗阻运动可使肌肉产生很多生理生化的变化。文章回顾了近年来不同学者和临床工作者针对抗阻运动改善肌肉减少症的数据,论述了抗阻运动防治肌肉减少症的机理,强调了抗阻运动和有针对性的营养调理对肌肉减少症的有效改善,对未来肌少症的治疗研究提供更清晰的方向。 相似文献

For a person undertaking regular exercise, any fluid deficit that is incurred during one exercise session can potentially compromise the next exercise session if adequate fluid replacement does not occur. Fluid replacement after exercise can, therefore, frequently be thought of as hydration before the next exercise bout. The importance of ensuring euhydration before exercise and the potential benefits of temporary hyperhydration with sodium salts or glycerol solutions are also important issues. Post-exercise restoration of fluid balance after sweat-induced dehydration avoids the detrimental effects of a body water deficit on physiological function and subsequent exercise performance. For effective restoration of fluid balance, the consumption of a volume of fluid in excess of the sweat loss and replacement of electrolyte, particularly sodium, losses are essential. Intravenous fluid replacement after exercise has been investigated to a lesser extent and its role for fluid replacement in the dehydrated but otherwise well athlete remains equivocal. 相似文献
