高原耐力训练中抗高原反应能力关系研究     

姚明义 《科技通报》2015,(2):22-24

目的:研究通过高原耐力训练,生成体内血胰岛素,并建立起与抗高原反应能力关系模型,评估人体在高原等恶劣环境下训练的生理机能。方法:研究对象为本校篮球队在青藏高原驻训的23名篮球队员,采用SPSS 13.0统计软件,测得运动员体内产生的血胰岛素聚合物Pluronic-b-PCL(Entry 0)和Pluronic-b-P(CL-co-BCL)的显著差异性,从而分析与抗高原反应能力的关系。引入有助于提高抗高原反应的半乳糖分子,通过DLS测试粒子表面的zeta电位值,分析受测运动员的调节纤维激酶值。结果:在阳离子型嵌段共聚物P(PEGMEMA16-co-PEGMA7)-b-PDMAEMA53中N/P比分别为0.3,0.6,0.8,1.5,2.5,3.0,8.0,受测运动员的生成的P(PEGMEMA-co-PEGMA)-b-PDMAEMA为2.155 g,0.1 mmol,PMDETA(104μL,0.5 mmol),Cu Cl(0.0258 g,0.25 mmol),在运动后24 h,血胰岛素与抗高原反应能力相关系数有所增大,运动后48 h,血胰岛素生成与抗高原反应能力相关系数有所较小,同时BP与调节纤维激酶相关系数增大,抗高原反应能力显著提高(P0.05)。结论:通过高原耐力训练,逐步增加红细胞和血红蛋白的生成,促进血胰岛素生成,改善血液输送氧的能力,使新进入高原的人发挥他正常的生理效能,指导高原训练和高原反应病症的治疗和预防。  相似文献   

Pacing profiles and pack running at the IAAF World Half Marathon Championships     

Brian Hanley 《Journal of sports sciences》2015,33(11):1189-1195

The aim of this study was to describe the pacing profiles and packing behaviour of athletes competing in the IAAF World Half Marathon Championships. Finishing and split times were collated for 491 men and 347 women across six championships. The mean speeds for each intermediate 5 km and end 1.1 km segments were calculated, and athletes grouped according to finishing time. The best men and women largely maintained their split speeds between 5 km and 15 km, whereas slower athletes had decreased speeds from 5 km onwards. Athletes were also classified by the type of packing behaviour in which they engaged. Those who ran in packs throughout the race had smaller decreases in pace than those who did not, or who managed to do so only to 5 km. While some athletes’ reduced speeds from 15 to 20 km might have been caused by fatigue, it was also possibly a tactic to aid a fast finish that was particularly beneficial to medallists. Those athletes who ran with the same competitors throughout sped up most during the finish. Athletes are advised to identify rivals likely to have similar abilities and ambitions and run with them as part of their pre-race strategy.  相似文献   

The Role of Endurance Contests in the Construction of Authority and Social Order in Rural China: Cases in the Qing Dynasty and the Republic of China     

Guohua Zheng 《国际体育史杂志》2015,32(8):1057-1070

By investigating four cases from the Qing Dynasty (1622–1911) and from the Republic of China (1911–1949), it was found that inter-village disputes normally arose because of uneven distribution of public resources in China's rural society. To settle the disputes, villagers tended to apply civil mediation, normally conducting endurance contests, rather than seek governmental arbitration. The authority and social order was thereby based on endurance contests. Conducting such contests was certainly advantageous to larger villages in their quest for more public resources. However, it simultaneously restricted their privatization of public resources, as the smaller villagers were able to equally raise their voices to resist them and to obtain their own public resources by proposing and participating in endurance contests. Although originally it was an unfair way of settling the disputes over uneven distribution of public resources in rural China, it gave hope to the disadvantaged to protect their own rights and interests at a time when governmental arbitration could not be relied upon.  相似文献   

运动员稀氧区域训练对肌肉纤维耐久力的影响     

王刚  吴波 《科技通报》2014,(9)

目的:研究运动员稀氧区域训练对肌肉纤维耐久力的影响。方法:分析18名运动员在常氧和高原低氧(模拟海拔4500 m递增负荷运动时,低氧通气反应速率、最大摄氧量以及最大耐力持续时间三个肌肉纤维耐久力评估指标的变化情况。结果:高原低氧训练时运动员低氧通气速率和最大耐力持续时间显著高于常氧对应值,高原低氧训练时,运动员最大摄氧量低于常氧对照组。高原低氧训练组,运动员在4个不同功率等级低氧通气速率,均高于常氧对应值,低氧通气速率在50%、75%以及100%最大功率时显著高于常氧对应值,最大摄氧量在各相对功率等级中,无显著性差异。运动员的低氧通气反应速率在高原低氧训练组至75%最大功率阶段降低,在75%至100%最大功率阶段基本保持平稳上升,不同相对强度下低氧训练组运动员最大摄氧量较常氧对应值显著降低。结论:高原运动训练下运动员肌肉纤维耐久力增强,疲劳时间降低,可提高运动员的运动能力。  相似文献

张海信  葛士顺 《科教文汇》2014,(26):68-69

建立大鼠大强度耐力训练模型,研究羊肚菌对大强度耐力训练大鼠自由基代谢和运动能力的影响。测定了大鼠骨骼肌组织中SOD、GSH-Px、CAT三种抗氧化酶活性和脂质过氧化产物MDA含量,也测定了大强度耐力训练大鼠的力竭时间。结果表明：同运动对照组相比较,运动加药组大鼠骨骼肌抗氧化酶SOD、GSH-Px、CAT活性有显著性或极显著性上升,MDA含量有显著性下降,同时运动加药组大鼠力竭时间与运动对照组相比显著延长,表明在大强度耐力训练大鼠骨骼肌自由基代谢当中,补充羊肚菌发挥着良好的清除自由基和抗氧化效果。  相似文献
