A Study On Exercise Load Intensity And Exercise Density Of Qinhuangdao Harbor District

According to the heart rate and exercise density index as the basis of scientific basis, through tracking video recording, Qinhuangdao harbor area 18 primary school part of the level of two of the 36 classes of three classes of teaching,(3 boys and 3 girls in each grade) in 108 middle school students and 108 middle school students in the fourth grade.

The results showed that Qinhuangdao harbor area level two physical education teaching content single, with track and field teaching as the main school, followed by the ball class, again is the martial arts class and gymnastics class. Qinhuangdao harbor area level two physical education average heart rate only girls in the standard range, the average heart rate of the boys are higher than the standard value; the average heart rate appears in the class 30 minutes, exercise load arrangement more rationalization. The average heart rate of the four categories of teaching items from low to high order followed by gymnastics, martial arts, ball, track and field class; Broadcasting, aerobics, sports dance and other exercises teaching content of the student exercise load, exercise intensity is lower than The Range of Appropriate Exercise Load Heart Rate in Primary. The average heart rate of female students was lower than that of male students, and the average heart rate of the whole students were within the effective heart rate range.The third and fourth grade are relatively reasonable; the third, fourth grade of the preparatory part, the basic part and the end of the fourth grade are in line with the rationalization of teaching time allocation, only three years to the end of the second year of physical education in Qinhuangdao City harbor level two physical education time arrangement, the third grade unreasonable, Time is higher than the reasonable allocation of time, Qinhuangdao harbor area level two physical education time allocation preparation part and the end part of the longer, the basic part of the distribution time is more reasonable. Qinhuangdao harbor area level two physical education, athletics, basketball, football, martial arts, for the level of teaching content of two physical exercises in the low density; to broadcast gymnastics, aerobics, sports and other physical exercises The density is smaller. Qinhuangdao harbor area level two physical education, Jianguo Road Primary School and Tiexinli Primary School physical education exercise density is the best, followed by cross-built primary school, the rest of the school practice density all show the practice of low density phenomenon.
