气象,即大气的状态和现象。如冷、热、干、湿、风、雨、霜、雾等各种物理状态和物理现象的统称。它对鱼类的活动与觅食影响极大,主要是:一、气象的变化直接影响气温、水温的变化。二、气象的变化牵连着气压的变化以及空气湿度的变化,从而使水中的溶氧量发生变化。三、气象的变化能改变水体的浑浊度。四、气象的变化往往给水体中带来新水和食物,如下雨或涨水。五、气象的变化可使温差出现明显的改变,如下露、下霜、下雪等现象。总之,气象的变化可以改变鱼类的活动规律和摄食习性,因为鱼类是一种冷血变温动物。所谓变温,是说它的体温不是恒定… 相似文献

初步简要地探讨了体育学与气象学的有机融合,并以北京奥运会的气象保障工作为例进一步说明了气象对于人类活动的重要意义,以及各类大型体育场馆所形成的局地小气象形式对于体育活动的影响。除了某些天气情况对客观体育环境的影响外,进行体育活动的主体也会受到各方面天气的干扰,从而影响运动员的正常发挥,取得好的比赛成绩。尤其以帆船比赛为例,是体育项目中比较依赖于天气环境的。在这类比赛中,气象保障工作显得尤为重要,而本文更是以青岛奥帆赛为例,详细地阐述了气象工作与帆船比赛进行过程的紧密联系。因此,气象学与体育学的有机融合是非常有意义的。 相似文献

对近10年来51场世界著名马拉松赛事的竞赛成绩和同期天气数据进行统计分析。结果表明,气温、海平面压和风速等单气象因子以及有效温度、风冷指数、舒适度等综合气象因素对马拉松成绩都有不同程度的影响,男、女运动员对天气状态反应不同。通过气象成绩分类进一步确定各气象因子在不同类别下对成绩影响的差异,为马拉松训练和比赛提供参考。 相似文献

天气条件对马拉松跑的影响:北京国际马拉松比赛调查分析 总被引：1，自引：0，他引：1
对北京国际马拉松比赛成绩与天气条件的相关性进行了定量分析。发现马拉松比赛成绩与天气因子如:气温、湿球温度、人类生物气象学指标相关显著。例如前十名运动员的平均成绩与气温的相关系数为r=0.8910。据此,将气象条件分为三类:适宜、一般、不适宜马拉松跑,从而确定了马拉松比赛的最佳天气指标。文中还提出“气象成绩”的概念。“气象成绩”占总成绩的一部分,随着天气条件的变化而波动并在某些运动项目(如马拉松跑)中起着重要作用。 相似文献

Athens sits in a basin approximately 450 km2 in area, surrounded by mountains and open sea. Anthropogenic emissions in conjunction with the topographical and meteorological conditions can result in high air pollution within the city. The pollutants of concern for athletes competing in Athens 2004 appear to be nitrogen dioxide (NO2), ozone and particulate (PM10) pollution. Exposure to elevated ozone concentrations has been reported to give rise to symptoms that include cough, chest pain, difficulty in breathing, headache, eye irritation and a decrease in forced expiratory volume in one second. All of these effects are likely to impact upon performance, and several studies of cyclists suggest this to be the case. In contrast, the impact of ambient concentrations of NO2 appears to be negligible on normal activities, but at high exercise intensities the impact remains unclear. The use of currently available information and models to predict the effect of ozone and other pollutants on elite athletes is problematical, since such models are based upon significantly lower ventilation rates than those achieved by some elite athletes. In addition, it is already known that the response to ozone can vary somewhat between individuals. Since the individuals who will be competing in Athens are physiologically very different to the participants in most published studies, it is difficult to predict individual responses. There is some evidence to indicate that adaptation to the adverse health and performance effects of ozone can occur, so that performance is partially recovered on re-exposure. The adaptation is not seen in all studies and appears to be dependent on several factors, including the initial sensitivity of the individual to ozone. Antioxidant supplementation has also been shown in some studies to partially ameliorate the adverse effects of ozone by counteracting the oxidative stress mechanism associated with this pollutant. Whether this transfers to performance enhancement per se remains unclear at present. Additional research is required to gain a sound understanding of the effects of a complex mixed air pollution exposure on the pulmonary function and performance of athletes exercising at high work intensities. 相似文献
