Application Research of Physical Activity Measurement Tool Compared with Traditional Observation Method in Exercise Density of Physical Education Class

Abstract

This paper takes the cricket course of Tsinghua University as an example to study how to quantitatively monitor the exercise density of physical education class through the three-axis accelerometer physical activity measurement tool, and obtain the calculation formula of effective exercise density in physical education class. Compare physical activity objective measurement method with physical education teachers’ traditional subjective observation method to find out the differences between these two measurement methods of exercise density in physical education classes. It will provide a reference for the exercise density evaluation in physical education classes and the physical activity monitoring of the students.
