Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to examine the effects of a kindergarten-based, parent-involved intervention during the upper kindergarten year (K3) on physical activity and physical fitness in preschool children.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a two-arm cluster randomized controlled trial. Kindergartens will be randomly allocated to two groups: the usual care group and the intervention group. The usual care group will continue with their usual curriculum, which includes 30 minutes of daily physical activity stipulated by the Hong Kong SAR Government's Education Bureau. The intervention group will receive an additional 2.5 hours of physical activity per week in addition to the stipulated 30 minutes of daily physical activity. Outcome measures will be examined at baseline, 10 months (post-intervention), and 16 months (follow-up).
