体育课的生理负荷是指课中学生从事运动动作练习的量和强度对机体的刺激程度。生理符合包括内部数据与外部数据两个层面。外部数据是学生练习的次数、总时间、总距离、练习密度、强度;内部数据是从事体育时机体在心律、血压等方面的变化。两者具有因果关系,外部数据是因,内部数据是果,一般成正比关系,即外部数据越大,内部数据也越大。生理负荷曲线反映体育课上各种练习对机体的刺激的大小,是生理负荷过程形象的反映。 Physiological load of physical education refers to the amount and intensity of physical activity that students in the class practice. Physiological compliance includes both internal data and external data. External data is the number of student practice, total time, total distance, practice density, intensity; internal data is engaged in sports when the body in the heart rate, blood pressure and other changes. The two have a causal relationship, the external data is due to the internal data is the result of a general positive relationship, that is, the greater the external data, the greater the internal data. Physiological load curve reflects the various physical exercises on the body to stimulate the size of the body, is a reflection of the process of physiological load image.
