黄柳菇多糖对运动大鼠部分抗氧化指标的影响

目的：研究黄柳菇多糖对大强度耐力训练大鼠血清、骨骼肌抗氧化能力的影响.方法：建立大强度耐力训练动物模型,测试运动后血液与骨骼肌组织中SOD、GSH-PX、MDA和T-AOC等指标,并观察其变化.结果：与安静组相比,大强度耐力训练组大鼠各项抗氧化酶活性明显下降,MDA含量显著增加;训练服药组相对于大强度耐力训练组大鼠的各项抗氧化酶活性有良好改善,MDA含量变化显著,显示骨骼肌组织损伤有良好改善.结论：黄柳菇多糖可以改善大强度耐力训练大鼠的氧化应激水平,使组织中抗氧化酶活性增强,有利于保护骨骼肌组织结构和功能的完整性,可作为天然抗氧化剂和微生态制剂进一步研究和开发.     

中学生排球运动员赛前情绪与比赛表现的相关研究

用《赛前情绪量表-T》和《集体项目运动员比赛表现自我评价表》,对209名中学生排球运动员进行了调查.通过T检验、方差分析和相关分析,结果发现:(1)中学生排球运动员的赛前情绪在其性别、年级、是否主力队员、运动等级及训练年限等方面存在显著差异;(2)个体失败焦虑、自信、社会期待焦虑和躯体焦虑与比赛表现自我评价均存在显著相关,运动员比赛表现自我评价与比赛胜负结果存在显著负相关.     

运动训练对大学生龙舟运动员体成分及心率变异性的影响

目的探讨运动训练对大学生龙舟运动员体成分及心率变异性的影响,旨在为认识龙舟训练对大学生运动员身体机能的影响提供一定的实验依据和理论基础。方法随机选取中山大学大学生龙舟运动员12名男生,在运动训练前后测试受试者的体重、BF%等体成分指标,并测试受试者极限负荷运动前后的短时程(5 min)HRV。结果 1.运动训练后,体成分各指标均下降;2.运动训练前和后,单次力竭运动后除HRp外RRp、RRm、RRn、SD、MSD、P50较安静时结果比较,均呈现下降;运动训练后安静时与运动训练前的对应时刻比较,各时域指标均呈现显著性升高;3.运动训练前,与安静时比较,力竭运动后LF、LF/HF呈显著性升高(P<0.05),而HF呈现极显著性下降(P<0.01);运动训练后,安静时的T.S.、HF与运动训练前的对应时刻结果比较,呈现显著性升高(P<0.05或P<0.01),而LF/HF呈现显著性下降(P<0.05);4.运动训练前仅有BMI与HRV指标之间存在相关,而运动训练后BMI、BF%、WHR均与HRV指标之间存在相关。结论运动训练后,大学生龙舟运动员改善了其体成分,提高了HRV,改善了自主神经中迷走神经和交感神经的平衡状态,出现机能节省化。     

大强度间歇训练对高中体育特长生800米成绩的影响

本文探讨了大强度间歇训练对体育特长生"800米跑"成绩的影响。方法:对20名(10男,10女)高中体育特长生进行"8wk"大强度间歇训练(以90%HRRmax强度运动2.5min,以50%HRRmax运动2min,每3次为1组,共2组,2组之间有3min休息),训练前与训练后对受试者进行800米跑成绩对比。结论:8周大强度间歇训练可以有效提高体育特长生800米跑成绩。     

省、市级专业运动员运动成就动机与训练态度及赛前情绪的相关研究

本文应用文献资料法、问卷调查法、数据分析法等多种方法,对省、市级专业运动员运动成就动机与训练态度及赛前情绪的关系作出了相关分析.结果表明,被调查运动员在运动成就动机方面不存在显著社会取向;两种取向运动成就动机、不同等级的运动员在训练态度上没有显著差异;对现有相关文献综述后得出,社会取向运动成就动机是影响赛前个体失败焦虑...     

大强度耐力训练抗氧化运动补剂研究进展

抗氧化运动补剂的研究已成为体育科学领域的研究热点,本文分析了大强度耐力训练中补充抗氧化运动补剂的必要性、综述了几种大强度耐力训练抗氧化运动补剂,并进一步对大强度耐力训练抗氧化运动补剂的研究进行了展望,为今后大强度耐力训练抗氧化运动补剂的研究深入发展提供理论依据.     

辅酶Q10对大强度耐力训练大鼠血液生化指标的影响

为探讨辅酶Q10对大强度耐力训练大鼠运动能力及疲劳恢复的影响,选用SD雄性健康大鼠32只,按完全随机原则分配到安静组、安静力竭组、运动力竭组和运动加药力竭组,每组各8只;建立大鼠大强度耐力跑台训练模型,检测大鼠血清Hb,Glu,Bla,LDH,CK和BUN等指标．结果表明：CoQ10能有效抑制运动训练后大鼠Hb含量下降;显著降低大强度耐力训练后大鼠血清LDH,CK等血清酶活性的升高和运动训练后BUN和Bla含量的升高．     

高校大学生运动训练疲劳应对分析——以广西第十二届民运会广西民族大学参赛学生为例

竞技体育快速发展,运动员为了取得优异的比赛成绩要长期承受大运动量、高负荷的训练。运动员训练过程中产生的疲劳现象主要与成就感的降低、情绪/体力耗竭和对运动的负评价程度相关。改善运动员心理承受能力和应变能力,减轻心理负担,根据个体运动潜力进行针对性训练,科学安排训练量、训练强度和训练时间等可以提高训练效率。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
