Using Video Direct Observation to Assess Children's Physical Activity During Recess

Area of Science:

• Pediatric physical activity research
• Observational methods in child behavior studies
• School recess physical activity analysis

Background:

• Traditional direct observation methods are limited in capturing continuous, individual-level physical activity (PA) data during school recess.
• Understanding children's PA patterns during unstructured time is crucial for public health and intervention strategies.

Purpose of the Study:

• To pilot video direct observation as a method for characterizing children's recess PA.
• To analyze recess PA overall and by sex and weight status.
• To compare PA levels across different recess locations (field, fixed equipment, court).

Main Methods:

• Utilized video direct observation to record 23 children (third to fifth grade) during two recess periods.
• Coded recorded data for PA duration, intensity (light, moderate-to-vigorous), location, and type.
• Employed one- and two-way analysis of variances to assess differences in PA across sex and weight status.

Main Results:

• The field area showed more sedentary behavior (39%) and light PA (17%) compared to fixed equipment (13%, 7%) and court (21%, 7%).
• Moderate-to-vigorous PA was highest on fixed equipment (71%) and court (68%) versus the field (41%).
• Boys exhibited more vigorous PA on the court (35% vs 14%), while girls engaged in more moderate-to-vigorous PA on fixed equipment and the field.

Conclusions:

• Video direct observation is a viable method for capturing comprehensive children's recess PA data, offering valuable contextual insights.
• PA intensity varies significantly by schoolyard location.
• Differences in PA type and intensity exist based on children's sex and weight status, highlighting the need for tailored approaches.
