Abstract:

Methods:117 healthy adolescents (57 girls and 60 boys) were recruited from 6 high schools in Xicheng District of Beijing (2 high schools of type 1, 2 of type 2, and 2 of type 3), and each 10 students were randomly selected from grade 1 and 2 in the high school. Polar Team 2 was used to measure physiological load in martial arts, throwing, jumping and basketball, and 639 persontime eligible data were collected.
Result:In martial arts and high jump class, duration of heart rate response (HRmax) below 60% in the new classes were significantly longer, while duration of moderatetovigorous physical activity (MVPA) was shorter than comprehensive courses and review courses(P<0.05). Students spent about an average of 24.6 (9-34) minutes in activities of HRmax below 60% in P.E.class, accounting for 54.7% of P.E. class time, an average of 17.3 (7-26) minutes in activities of HRmax between 60%-80%, accounting for 38.4% of P.E. class time, and an average of 3.5 (0-20) minutes in activities of HRmax higher than 80%, accounting for 6.9% of P. E. class time.
Conclusion:This physical load cannot achieve the goal of improving adolescents’ physical fitness. Government should strengthen the continuing education of PE teachers and update their knowledge constantly, in order to maximize the physical education benefit for adolescents.
