Proposal for an Enhanced Physical Education Program in the Primary School: Evaluation of Feasibility and Effectiveness in Improving Physical Skills and Fitness

摘要

A large proportion of children do not reach the recommended levels of physical activity for health. A quasi experimental study with nonrandom assignment was performed to evaluate the effectiveness and feasibility of a school-based physical education intervention aimed at increasing the levels of moderate-to-vigorous physical activity (MVPA). Methods: Ten classes from 4 primary schools, including 241 children aged 8 to 10 years, were recruited. The experimental group (n = 97) received 4 additional sessions/week of 60 minutes of MVPA for 8 months. The control group (n = 135) continued their standard program (2 sessions of 50 minutes/week). Motor abilities (standing long jump, handgrip strength, Harre circuit, sit and reach), physical fitness (Yo-Yo Intermittent Recovery Level-1), anthropometric measures (body mass index, waist to height ratio), and self-efficacy (Perceived Physical Ability Scale for Children) were evaluated at baseline and after the intervention. Results: The experimental group significantly improved in the Harre circuit both in males (P<.001) and females (P<.01), whereas physical fitness test improved only in males (P<.001). Males in the experimental group improved the perception of self-efficacy in coordinative abilities (P=.017). Conclusions: The proposed school-based MVPA program showed effectiveness and feasibility. The differences observed by gender highlight the need. to use different strategies to increase the involvement of all the participants.
