The aim of this study was an evaluation of the influence of HiLoon aerobic performance and its physical effects. Elite swimmers、 collegestudents major in physical education and rats were exposed to simulatedaltitude in a decompression chamber and the followings were investigated:(1) erythropoiesis and erythropoietin,(2)maximal oxygen uptake,(3)body weight and body composition,(4)serum parameters of metabolism andhormone,(5)erythropoietin gene expression in kidney and vascularendothelium growth factor gene expression in heart.1 Effects of simulated "living high-training low" on aerobic performancein elite swimmersFourteen swimmers (10 men, 4 women) from Shandong swimming team weredivided into two groups: experimental group (living high-training low,n=8,6men,2women),living at a simulated altitude of 2,800m for 13 to 14 hours per day for 3weeks in a decompression chamber and training at sea level; control group(living low-training low, n=6,4 men,2 women),living and training at sea level.

为系统探讨高住低练对机体有氧能力的影响及其机制，本研究利用低压舱来模拟高原气压条件，分别以优秀游泳运动员、体育专业大学生和大鼠为实验对象，从以下几个方面来初步探讨模拟高住低练对机体的影响：(1)红细胞生成和EPO，(2)最大摄氧量和无氧阈，(3)体重和身体成分，(4)血清物质代谢指标及激素水平，(5)大鼠肾脏EPO和心脏VEGF基因表达。1 模拟高住低练对优秀游泳运动员有氧能力的影响 14名山东省游泳队运动员(男10人，女4人)，随机分为两组：实验组(模拟高住低练组，男6，女2)和对照组(低住低练组，男4，女2)。

Methods The distribution of fos-like immunoreactive neurons in telencephalon, diencephalon, midbrain and pons were examined in 10 "behavioral despair" rats and 10 "simple forced swimming" rats, and the distributions of FLI neurons of the two groups were compared by fos-Ab immunohistochemistry methods.

采用不同强度强迫游泳应激造成绝望行为模型和单纯强迫游泳模型大鼠（Wistar 系雄性，体重160～180 g）各10只，在其端脑、间脑、中脑和脑桥切片上各做抗fos蛋白免疫组化染色，40倍光镜下观察和计数各部位内fos蛋白免疫阳性神经元及其数目，并进行两组之间的比较。

Results The behavioral features of the aged learning and memory impaired rats were as follow: 1 There was little change happened to the sample performance. 2 The spatial reference memory had obviously declined. The swimming times of searching the hidden platform in the place discrimination performance, the swimming time in a 40cm annulus at the primary platform place (A40T) and the platform crossings in the probe trial performance were the most suitable indexes for mirroring the spatial reference memory abilities. 3 The spatial working memory had not decreased so clearly.

结果 老年学习记忆损害大鼠的行为学改变特征为：1简单学习记忆任务的学习能力没有明显变化。2空间参考记忆能力明显减退，寻找平台所用的游泳时间，40cm环内游泳时间(A40T)和平台跨越次数是反映老年学习记忆害大鼠空间参考记忆能力的理想指标。3空间工作记忆能力减退不明显。

Sighed Jones,"First, my wife wanted me to drive her to the train station and it took her ten minutes to get ready. Then when we were going to cross the harbor, the drawbridge was out of order and I had to swim across to run to rent a helicopter to take her across. Then I swam back, hopped on a taxi and came here."

我的老婆要我开车送她去火车站搭火车，她要十分钟才能打扮好，但是过海时吊桥坏了，我不想迟到，便游泳过海，跑去租了直升飞机飞回来，载老婆过去了，之后，我再游泳过来，跳上的士赶回来！

In order to strive to make the Chinese women swimming in breaking through and long-term developing road of a short time of 2008 Olympic Games,this text proposes: Set up the training base of national-level scientific research,carry on multi-disciplinary comprehensive research;Establish the advantage events of the woman swims,divide into groups and tackling key problems;Solve "ex-service and early" problem,lengthen sport life-span of topnotch athletic;Strengthen two national team,construction,the strategic hinterland of China of team in a more cost-effective manner,form the colony advantage of the project;Strengthen the work of team's management,study the anti-excitant actively ect.

为力求中国女子游泳在08年奥运会的短期突破和长期发展之路，本文提出：建立国家级科研训练基地，进行多学科的综合研究；确立女子游泳的优势项目，实行分组攻关；解决"早退役"问题，延长优秀选手的运动寿命；大力加强国家队二、三线队伍的建设，形成项目的群体优势；加强队伍管理工作，积极进行反兴奋剂研究等5点攻关对策。

MAIN OUTCOME MEASURES: Spatial learning and memory, mean escape latency, times of passing through the platform point, swimming distance percentage of the first quadrant, and swimming distance percentage of the 20％ marginal area.

主要观察指标：空间学习记忆能力，平均逃避潜伏期，穿过平台次数，第一象限游泳距离百分率，20％边缘区游泳距离百分率。

And the scores of the inner annulusand the first quadrant swimming time the rat fetuses got in Morris water maze test were analyzed with spss 11.0Results: There was significant differences in the scores of the inner annulus(0.1193±0.0810) and the first quadrant swimming time(0.5233± 0.1375 )that got in Morris water maze between the 30 min group and the

统计各组在第一象限的游泳时间及在内环的得分。所得分数用统计软件spss 11.0进行评价。结果超声辐照30min组，成年期大鼠在Morris水迷宫测试中第1象限游泳时间(0.5233±0.1375)及内环所得分数(0.1193±0.0810)与对照
