Introduction. Physical activity (PA) plays a crucial role in childhood and adolescent development, influencing motor competence and overall health. Despite extensive research on PA benefits, inconsistencies remain regarding its impact on specific motor skills among adolescents in different socioeconomic contexts. This study aims to examine the differences in motor abilities between physically active and less active students aged 12-13 in the Mekong Delta, Vietnam.
Material and Methods. A total of 125 students (68 males, 57 females) participated in this cross-sectional study. PA levels were assessed using the Physical Activity Questionnaire for Children (PAQ-C), classifying students into active (PAQ-C ≥ 2.73) and less active (PAQ-C < 2.73) groups. Anthropometric measurements, including height, body mass, and BMI, were recorded. Motor competence was evaluated using a modified EUROFIT test battery, assessing abdominal, lower back, upper limb, and lower limb strength, as well as explosive leg power. Data were analyzed using the Student’s t-test (p < 0.05).
Results. Physically active students exhibited significantly higher body mass, BMI, and superior performance in abdominal strength (p < 0.001), upper limb strength (p < 0.001), and standing long jump (p < 0.001). No significant differences were observed in lower back (p = 0.252) and lower limb strength (p = 0.098).
Conclusions. Higher PA levels correlate with improved motor competence, particularly in core strength and explosive power. These findings highlight the need for targeted PA interventions in school curricula to enhance students’ physical development.
