In PE teaching and training, it is very important to measure the exercise amount and intensity rationally and accurately.Currently, there are many methods to measure such as testing heart rate, blood pressure, hemoglobin, urinary protein and determination of lactic acid in blood, etc. Widely used in sports training class, or test heart rate, which is also used by the majority of primary and secondary physical education teachers.Generally speaking, we use the highest point of heart rate and the lowest point of time, to illustrate the rationale for a class of exercise arrangements ; Using the highest pulse value, the duration, and the average number of pulses (ie, measured throughout the lesson
