两种大强度间歇训练对优秀公路自行车运动员有氧能力的影响          下载免费PDF全文

屈成刚  唐一丹 《体育科研》2019,(1):64-71

目的：比较两种大强度间歇训练手段对优秀自行车运动员有氧运动能力的影响。方法：将15名备战全国“十三运”的云南省自行车队男子运动员随机分为3组， S组训练方案采用SIT/耐力训练， H组训练方案采用HIIT/耐力训练， C组为对照组，进行传统耐力性训练；训练持续3周。训练前后进行递增负荷测试和有氧运动能力测试，测试指标包括最大摄氧量绝对值（VO2max）、最大摄氧量相对值（VO2max/kg）、每分通气量（VE）、最大心率（HRmax），并通过公式计算每搏输出量（SV），以及测试递增负荷后即刻血乳酸（BLA）、最大有氧功率（P）和40 km个人计时成绩进行了测试。结果：（1）3周训练后，S组运动员VE、HRmax、SV、VO2max、VO2max/kg、P和ITT40km均较训练前有显著性提高（P＜0.05）；H组运动员VE、VO2max/kg、ITT40km较训练前有显著性增加（P＜0.05），BLA有显著性的下降（P＜0.05）。（2）S组运动员ΔVE、ΔHRmax、ΔSV、ΔVO2max、ΔVO2max/kg、ΔBLA、ΔITT40km显著提升（P＜0.05），且优于其余两组；H组仅ΔITT40km存在明显提升（P＜0.05）。结论：间歇训练结合耐力训练对优秀公路自行车运动员的呼吸系统、有氧供能系统可产生积极的影响；而且，SIT结合耐力训练较HIIT结合耐力训练或传统耐力训练更能提高公路自行车运动员的有氧代谢能力和有氧运动能力，训练效果更佳。  相似文献

The Influence of Hygroscopic Materials on the Fluctuation of Relative Humidity in Museums Located in Historical Buildings     

C. Ferreira  V. P. de Freitas 《文物保护研究》2020,65(3):127-141

ABSTRACT

The preservation of artefacts in museum collections is profoundly affected by fluctuations in temperature and, especially, relative humidity (RH). Since the late nineteenth century, many studies have been carried out on the best way to control hygrothermal conditions. In old buildings located in maritime temperate climate zones (such as Portugal) with strong thermal inertia, and which have low ventilation rate (relative to the volume and number of visitors), daily and seasonal hygroscopic inertia may help to assure the maintenance of RH stabilization conditions. The use of expensive active systems may be minimized through the passive behaviour of internal finishing building materials. This work presents the results of an experimental laboratory study conducted in a flow chamber to demonstrate the enormous potential of hygroscopic materials in stabilizing interior relative humidity. Based in these results and in-situ monitoring in a museum housed in a building, located in Porto, with a typical construction of the 1950s (granite masonry and reinforced concrete slabs), a numerical analysis was done to quantify the influence of hygroscopic materials in stabilizing the interior relative humidity.  相似文献   

3-min all-out effort on cycle ergometer is valid to estimate the anaerobic capacity by measurement of blood lactate and excess post-exercise oxygen consumption

The purpose of this study was to investigate the use of a single 3-min all-out maximal effort to estimate anaerobic capacity (AC) through the lactate and excess post-exercise oxygen consumption (EPOC) response methods (AC_{[La^?]+EPOCfast}) on a cycle ergometer. Eleven physically active men (age?=?28.1?±?4.0?yrs, height?=?175.1?±?4.2?cm, body mass?=?74.8?±?11.9?kg and ?O_2max?=?40.7?±?7.3?mL?kg^?1?min^?1), participated in the study and performed: i) five submaximal efforts, ii) a supramaximal effort at 115% of intensity of ?O_2max, and iii) a 3-min all-out maximal effort. Anaerobic capacity was estimated using the supramaximal effort through conventional maximal accumulated oxygen deficit (MAOD) and also through the sum of oxygen equivalents from the glycolytic (fast component of excess post-exercise oxygen consumption) and phosphagen pathways (blood lactate accumulation) (AC_{[La^?]+EPOCfast}), while during the 3-min all-out maximal effort the anaerobic capacity was estimated using the AC_{[La^?]+EPOCfast} procedure. There were no significant differences between the three methods (p?>?0.05). Additionally, the anaerobic capacity estimated during the 3-min all-out effort was significantly correlated with the MAOD (r?=?0.74; p?=?0.009) and AC_{[La^?]+EPOCfast} methods (r?=?0.65; p?=?0.029). Therefore, it is possible to conclude that the 3-min all-out effort is valid to estimate anaerobic capacity in physically active men during a single cycle ergometer effort.  相似文献   

考虑偏差路径的电动汽车充电站选址和定容     

朱书研  杨斌  朱小林 《上海海事大学学报》2019,40(1):44-50

为在电动汽车推广初期提升其在物流配送领域的接受度,缓解途中驾驶人员的"里程焦虑",对电动汽车充电站的选址和定容进行合理规划。不仅考虑驾驶人员为给电动汽车充电而愿意偏离最短路径行驶的偏差路径,还考虑电动汽车进入充电站后的等待时间,提出一个双目标混合整数规划模型。以偏差路径中的车流量来模拟充电需求,以最大化满足路径中需求与最小化平均等待时间两个目标之间的相互平衡作为衡量选址和定容合理性的指标,从而得到充电站的合理规划。结果表明:单次充电行驶里程、偏差距离和服务速率对充电站的选址和定容有重要影响。  相似文献   

Meeting Information Needs through Global Partnerships: A Roadmap to Becoming a Global Health Sciences Library     

Nandita S. Mani  Megan Fratta  Rebecca Carlson  Michelle Cawley 《图书馆管理杂志》2020,60(7):830-851

Abstract

Supporting global health priorities through the development of robust health science librarianship partnerships is of significant importance. Increased demand for synthesizing evidence-based information, collating quality resources, and increasing research productivity to improve human health requires integration of library and information science skills and expertise. The Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill (UNC), exists to be an indispensable partner in health information and knowledge, teaching and learning, and research. As global efforts at UNC expanded, the HSL sought to ensure that our global engagement strategy and integration were aligned with campus priorities and partner needs. The HSL created a global research partnership plan: identify resources that improve efficiency, increase access to information, build in-country capacity and expertise—all while strengthening collaborations across multiple countries. Creating a meaningful and sustainable engagement strategy was central to envisioning our path forward and can be used as a framework for consideration by librarians in similar settings.  相似文献

试论保持党的先进性对提高党的执政能力的作用和意义     

包学文 《江苏经贸职业技术学院学报》2011,(6):42-45

中国共产党作为领导中国人民进行社会主义现代化建设的坚强领导核心,其长期的执政实践经验表明,坚持党的先进性,提高党的执政能力,关乎党的生死存亡,关乎社会主义事业的兴衰成败。因此,必须采取有效措施来保持党的先进性,提高党的执政能力和执政水平,巩固党的执政地位。  相似文献
