介绍了利用二元回归方程求体育课平均脉率的方法。此法只需测课前安静脉率和课结束整理活动后即刻脉 率二项指标。从而简化了传统点算法和面积计算法繁琐的测试程序,避免了由于检测脉搏对学生上课造成的影响。 同时可使教师更专心于课上教学。为广大体育教师合理调控体育课的运动负荷提供了简便的科学方法。 The method of using bivariate regression equation to find the average pulse rate of physical education class is introduced. This method only need to measure the calm pulse rate before class and finishing the pulse rate immediately after finishing class two indicators. Thus simplifying the traditional point algorithm and area calculation method tedious test procedures, to avoid the pulse due to the impact of class students. At the same time can make teachers more focused on class teaching. For the majority of physical education teachers reasonable regulation sports load provides a simple and scientific method.
