在ＳＤ大鼠运动超负荷和压力超负荷模型上，采用ＲＭ—６０００型多导生理记录仪，ＢＥＣＫＭＡＮ４２型自动生化分析仪对大鼠体重、血压、心率、高密度脂蛋白（ＨＤＬ）和低密度脂蛋白（ＬＤＬ）等指标进行了测定。结果表明，一般运动负荷组体重增加，心率降低、血压恒定，ＬＤＬ显著性降低（ｐ＜０．００１），ＨＤＬ显著性升高（ｐ＜０．０１）；运动超负荷组体重显著性降低，心率增加，血压上升，ＬＤＬ升高，ＨＤＬ显著性降低（ｐ＜０．０１）；压力超负荷组体重、心率增加，血压呈高血压指标，ＬＤＬ升高显著（ｐ＜０．０１），ＨＤＬ降低显著（ｐ＜０．００１）。上述结果表明，一般运动负荷可使机体血压恒定，心率减慢，血脂代谢水平改善，运动超负荷可使机体体重下降，心率、血压升高，血脂代谢水平异常，并与高血压型相似，对维持健康水平不利
The dynamic changes of body weight, blood pressure, heart rate, high density lipoprotein (HDL) and low density (LDL) in rats were observed by using the RM-6000 multi-channel physiology recorder and BECKMAN42 automatic biochemical analyzer. Lipoprotein (LDL) and other indicators were measured. The results showed that body weight increased, heart rate decreased, blood pressure decreased, the LDL decreased significantly (p <0.001) and the HDL increased significantly (p <0.01) in the general exercise load group. The body weight decreased significantly in the exercise overload group, Heart rate, blood pressure, LDL increased, HDL significantly reduced (p <0.01); pressure overload group body weight, heart rate, blood pressure were indicators of hypertension, LDL increased significantly (p <0.01), HDL Reduced significantly (p <0.001). The above results show that the general exercise load can make the body constant blood pressure, heart rate, blood lipid metabolism improved, exercise overload can make the body weight loss, heart rate, blood pressure, blood lipid abnormalities, and similar to the type of hypertension, Maintaining a healthy level is not good
