Abstract:
Objective:To evaluate the effectiveness of the SHARP intervention model for increasing students’ moderate to vigorous physical activity (MVPA) levels,and to provide a reference for physical activity enriching intervention among middle schools students’.
Methods:One-year interventional teaching was carried out in 6 schools selected in the terms of scale and demographics from Nanjing City, Jiangsu Province. Data were collected during physical education (intervention group 105, control group 113; pre-intervention 119, post-intervention 99) data for 218 students. MVPA was assessed at baseline and post-intervention using the Observed Health and Coaching Time System(SOFIT). Interviews with 19 teachers were conducted with intervention schools to explore teachers’ views on interventions.
Results:The two-way analysis of variance showed that the intervention of the SHARP model had a significant impact on MVPA, VPA, and motor skills of middle school students. Proportion of the average MVPA class time of the intervention school students(62.80±9.11), and the average proportion of the VPA class time of the intervention school(24.33±12.55), the average class time for intervention in the school’s mastery of skills(32.34±11.78)(t=-7.46, -4.82, -12.08, P<0.01). The MVPA of students in control school remained relatively constant while the VPA decreased. Classroom teaching capability improved significantly in intervention schools, which was further confirmed by teacher interviews.
Conclusion:The SHARP intervention model can effectively increase the MVPA level of middle school students.
