Acti Graph GT3X Assessment Physical Education Activity Intensity Applied To The Junior High School Physical Education

Physical Education Activity Intensity refers to a series of physical burden borne by the students in Physical Education,Activity Intensity is an important indicator of the completion of Physical Education teaching objectives.China's Physical Education Activity Intensity measurement method is generally measured heart rate,"Acti Graph GT3X" is used as a new type of wearable device that objectively measures physical strength and energy consumption,and is used less in the Physical Education Activity Intensity measurement and evaluation.Therefore,it is interesting to use the "ActiGraph GT3X" to measure the Physical Education Activity Intensity.This study aims to analyze the physical education Activity Intensity,analyze the actual situation of Junior High School Physical Education in Lin Fen City,and provide scientific basis for "improving physical education and improving teaching level".The object of this experiment is Physical Education Activity Intensity,which mainly analyzes the actual situation of Physical Education Activity Intensity by using literature,test,educational observation and mathematical statistics.In the experiment,274 middle school students aged 11-15 were selected,including 100 in the first grade,82 in the second grade and 92 in the third grade.There were 27 classes in the ball class,track and field course and gymnastics class.814 people.The result show that:(1)the average sports load of junior high school physical education is 3.8MET,which belongs to medium-intensity exercise;(2)junior high school physical education sports load is higher than that of female;(3)junior high school physical education junior high school sports load the lowest,About 3.6MET,junior high school sports load the highest grade,about 4MET.(4)junior high school physical education class physical education class sports load is 3.4MET,ball sports class sports load is about 3.8MET,track and field class sports class sports class sports load is 3.4MET,ball sports class sports load is about 3.8MET,track and field class Physical exercise load is about 4.0MET.Physical exercise part of the exercise load is the highest class of gymnastics class,the basic part of the sports load is the highest track and field class,the end part of the gymnastics class sports load the lowest.
