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。

From the angle of sports training, the concept of traditional competitive swimming discipline puts the emphasis on the advancement of cardiovascular system's function and takes"speed endurance"as supported platform for physical performance; whereas the concept of modern competitive swimming discipline puts the emphasis on skeletal muscle proof receptor inside lactic acid environment , be able to spread retractile ability's discipline and takes"strength stamina"as supported platform for physical performance.
