对中方10名竞走运动员(世居海拔2260m)和日方10名竞走运动员(居住平原,10m)在青海多巴高原的训练基地(海拔2366m)和平原(海拔10m)训练期间进行了4min递增负荷实验的血乳酸,心率的测试。结果表明:高原训练初期与后期相比,中日双方运动员的无氧阈速度ATV分别由3.of士0.42m/s、2.78±0.52m/s升至3.22±0.25m/s、3.30±0.34m/s,血乳酸一速度曲线右移程度较大。中日运动员高原训练后期和初期的同级负荷运动心率相比均有所降低。同时从ATV与比赛平均速度的相关系数看(男子运动员r=0.85,P<0.01;女子运动员r=0.65,P<0.05)它们之间存在较高度的相关。  相似文献

调查了辽宁省柔道队运动员(男9,人,女11人)的膳食及血脂水平,从摄取的食品组成中发现动物性食品比重较大,热能与营养素的摄取基本满足需要,所摄入的氨基酸模式符合理想模式。但存在胆固醇摄入量过高(男队员为1045.6±481.7mg,女队员为898.6±486.0mg),脂肪酸中饱和脂肪酸比重大,P/S比男女队分别是0.66±0.18和0.92±0.19等现象。  相似文献

力竭运动对大鼠微循环的影响   总被引:4,自引:0,他引:4  
本文观察了10只大鼠安静时、力竭运动后即刻、力竭运动后24小时耳廓微循环的动态变化。观察结果表明:力竭运动后即刻大鼠微循环发生明显障碍(P<0.01)。休息24小时后微循环障碍得以明显改善(P<0.01及P<0.02).但是,与安静时比较,血管形态积分值和总积分值仍有显著性差异(P<0.02),而流态积分值和管周状态积分值已无显著性差异(P>0.05)。  相似文献

Wingate测试法的代谢研究   总被引:28,自引:2,他引:26  
初步研究30sWingate测试的做功与体成分、能量代谢的相关,以及运动后血乳酸恢复特点与个体无氧阈(IAT)的关系。结果显示:30sWingate运动测试中最高功率(PP)与去脂体重、10s测试平均功率有显著相关,相关系数(r)分别为0.962(P<0.01)和0.866(P<0.02);30s运动后30min内各时段的血乳酸恢复百分数与IAT值相关显著(0.80≤r≤0.951,P<0.05),分别建立了用去脂体重推导PP值和用第15min血乳酸恢复百分数推导IAT值的回归方程。经过与国内外有关研究结果的比较、分析认为,通过体成份、30sWingate测试及运动后第15min血乳酸恢复百分数的连续测定,有可能实现有氧、无氧两种代谢能力的一次性测试和评定。  相似文献

分析了太阳特大高度的船位圆在墨卡托海图上的投影、曲率半径和曲率中心,并且由此得到如下结论。(1)求特大高度船位线的方法可推广至太阳高度h⊙≥87°36′。在墨卡托海图上以(φA,t⊙G)点为中心,真顶距为半径所作的船位线的误差不超过0.1nmile.(2)当以太阳地理位置为中心,真顶距为半径作船位线时,一般情况下其误差小于0.5nmile。只有在太阳赤纬δ⊙≥14°,且h⊙→88°时,船位线误差可达0.5~0.9nmile;h⊙=87°36′~88°时,船位线误差可达0.5~1.5nmile.  相似文献

温针灸和穴位注射影响运动员血清CK,SOD活性的研究   总被引:7,自引:0,他引:7  
本实验将20名男运动员随机分为对照和实验两组。实验组每日温针灸和穴位注射一次,连续五日;第五天进行5000米跑。分别测定运动前及运动后1小时、16小时、24小时血清CK、SOD活性。实验结果表明:1.对照组CK在运动后24小时内持续增高;SOD在运动后下降明显P<0.05。2.实验组CK恢复提前;SOD在运动后保持相对恒定,相应时刻与对照组相比差异显著(P<0.01,P<0.001)  相似文献

Since the late 1960s,culture has been considered tighter with communication.Culture IS based on the community of communication.Communication involves people and their environment.Thus culture is an important factor in communication.Today with modem economic and technological development,intercultural communication is mole important than ever before. When people from different cultural background communicate with each other,their social stereotype pattern of behavior, their habits of language and thought differ from one another,because these are the possible factors that affect intercultural communications.Culture norms also change,culture may be transferred as signs but we have to study and understand the above carefially.  相似文献

The thesis mainly discusses the character of the heroine in Charlotte Brontes famous novel "Jane Eyre". There are three major parts-introduction,analysis which is the main body of the thesis,and conclusion.Jane Eyre,the heroine,is a new woman image who requires independence equality and freedom.The thesis just analyzes Janes these rebellious characters through four peroods of her experiences.First,in her childhood,she has shown her rebellious spirit.As an orphan,Jane suffers a lot of misery.Not only her aunt treats her cruelly,her cousins despise her,but also do servants have a prejudice against her.In Janes immature heart, she is unwilling to bear ill treatment.She rebels them bravely.Second,when she studies at Lowood,her rebellious spirit is exposed furtherly.Her view doest stay in Mrs Reeds,instead turns to the whole society.She makes hypocrisy of so-called charity to be discovered completely.At the same time,she declares her independent,equal rebellious thought to her friend-Helldn who endures oppression willingly.Third,she,as a governess in Thornfield Hall falls in love with Rochester-her master.During this period,her thought grows into maturity.Thought she loves him passionately,she never loses her dignity and independence for him.When she knows his mad wife still lives,she makes up her mind to leave him.For she doesnt want to become his mistress.Fourth,her refusal of St Johns proposal of marriage depicts Janes character.She knows John does not love her at all and his purpose of marriage is only to perform his great task missionary.Jane does want to become a sacrifice.She breaks traditional morality,then she goes back to Rochester.  相似文献

The context of a word consists of the other words surrounding it and the situation in which it is used.When we come across a new word in our reading,instead of looking it up in a dictionary for its definition,we can guess its meaning from its context.  相似文献

"Midnight"is a poem written by Archibald·Lampman,a Canadian poet,who loved nature very much,but his poor health prevents him from being very active in the outdoor life.So he is often the quite,thoughtful observer of nature in his poems.This article mainly talks about how to appreciate the poem in the following aspects:word selecting,rhyme,sentence structure and atmosphere.After reading this poem,we cannot get rid of the air of horror and mystery."Midnight" reveals another aspect of the nature:wild,rough and unknown.There is something else in the nature that can awe human beings even though we don't know what it is.  相似文献

当代中国武术经历了时代的沧桑和变迁,在历经了文化和历史的发展与洗礼之后,依然发展、繁衍至今。在这样一个漫长的过程中,伴随着以社会环境和社会人群价值取向为主的变迁与变化,当代中国武术的发展与当代社会的发展正逐渐的呈现出某些相背离和不和谐的表象。通过研究,我们发觉中国武术中原本一些内在的东西正在不断的被遗忘,正在不断的流逝。本文试从中国武术在当代发展中的问题境域入手,解读中国武术在当今世界和社会中存在的一些问题,希望能够从中找到中国武术发展的"合法性"或"合时性"的内在依据,以挺立中国武术的脊梁。  相似文献
