Official title

Combating Physical Inactivity Pandemic by Promoting Physical Fitness Education and Physical Activity-Embedded Curriculum in Kindergartens

Overview

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

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).

Interventions

  • Other Usual Care Control
    30 minutes of physical activity on each school day.
  • Behavioral Physical Activity Enhanced Curriculum
    Additional 2.5 hours of physical activity per week in addition to the stipulated 30 minutes of daily physical activity.

Primary outcome measures

  • Change in Physical Activity [Time frame: Baseline and 10 months]
  • Change in Cardiorespiratory Fitness [Time frame: Baseline and 10 months]
Secondary outcome measures (12)

  • Change in Flexibility [Time frame: Baseline, 10 months, and 16 months]
  • Change in Agility [Time frame: Baseline, 10 months, and 16 months]
  • Change in Balance Ability [Time frame: Baseline, 10 months, and 16 months]
  • Change in Muscle Power [Time frame: Baseline, 10 months, and 16 months]
  • Change in Body Mass Index [Time frame: Baseline, 10 months, and 16 months]
  • Change in Waist Circumference [Time frame: Baseline, 10 months, and 16 months]
  • Change in Body Fat [Time frame: Baseline, 10 months, and 16 months]
  • Change in Fat-Free Mass [Time frame: Baseline, 10 months, and 16 months]
  • Change in Sedentary Behavior and Screen Time [Time frame: Baseline, 10 months, and 16 months]
