Effects of School-Based Physical Activity Program on Students' Moderate-to-Vigorous Physical Activity and Perceptions of Physical Competence

Abstract

Background: The study examined the effects of school-based program on students' self-reported moderate to vigorous physical activity and physical competence, and associated links to gender, grade, body mass index, and physical education assessments.

Methods: Participants were 240 middle school students (143 intervention, 97 control) from 3 small cities in North-East Finland. The intervention group received task-involving climate support in physical education classes and additional physical activities during school days across 1 year.

Results: The intervention group's physical competence increased, whereas the control group's competence remained stable across the period. However, physical activity levels were stable in both groups. The findings also showed that body mass index was negatively associated with physical competence and activity in the intervention group at the follow-up measure. Physical education assessments were positively related with only the baseline scores of physical competence in the intervention group. In contrast, the assessments had positive relationships with physical competence and activity of control group students.

Conclusions: The present program was an effective protocol to increase student's perceptions of physical competence. Since the quantity of school physical education including recess activities cannot be dramatically increased, positive learning experiences should be provided, and thus, support perceptions of physical competence.
