Accelerometer-Based Physical Activity Levels Differ between Week and Weekend Days in British Preschool Children

Area of Science:

• Pediatrics
• Public Health
• Sports Science

Background:

• Physical activity (PA) is crucial for children's long-term health.
• Limited research exists on weekday vs. weekend PA patterns in UK preschoolers.
• Objective measurement of PA is needed to accurately assess children's activity levels.

Purpose of the Study:

• To compare physical activity (PA) levels between weekdays and weekend days in UK preschool children.
• To objectively measure PA using accelerometers in preschool-aged children.
• To determine if preschool children meet recommended daily PA guidelines.

Main Methods:

• 185 preschool children (4-5 years) from central England wore triaxial accelerometers (GENEActiv) for 4 days.
• Activity data was analyzed using specific cut-points for light, moderate, and vigorous PA (MVPA).
• Time spent in sedentary behavior and MVPA was calculated for weekdays and weekend days.

Main Results:

• No children met the UK recommendation of 180+ minutes of daily PA.
• Preschool children spent 91.9% of weekdays and 96.9% of weekend days in sedentary behavior.
• Moderate-to-vigorous physical activity (MVPA) comprised 6.3% of weekdays and only 2.0% of weekend days.

Conclusions:

• British preschool children exhibit high levels of sedentary behavior, particularly on weekends.
• Weekend days show significantly lower moderate-to-vigorous physical activity (MVPA) compared to weekdays.
• Weekday PA engagement offers crucial opportunities for activity that may be missed on weekend days.
