dc.description.abstractThe purpose was to evaluate the implications of a proficiency barrier (PB) for physical activity (PA), sedentary time (ST) and weight status (WS) in a two-stage study. In Stage 1, motor quotient (MQ) cut-off values, based on the KTK test, for differentiating overweight/obese from normal weight, and sedentary from non-sedentary were identified in a sample of 734 children (353 girls) of 10 years of age. In Stage 2, the cut-off values were used to define low and high (respectively below and above the PB) MQ groups among 217 youth (118 girls) of 12.9(0.4) years of age. WS, PA and ST in the two MQ groups were compared at baseline and 1.5 years later. Chi-square tests were used to test the independence of low and high MQ classification on MS, moderate-to-vigorous PA, and sedentary time. Odds of being overweight/obese and sedentary according to MQ status at baseline were calculated. MQ of 79 for girls and 75 for boys were defined as the PB. In girls, the PB predicted significantly different classifications of WS, and a combination of WS and moderate-to-vigorous PA. In boys, the PB predicted significantly different classifications based on combined WS and moderate-to-vigorous PA at baseline. Having a MQ below the PB was associated with a 2.78 higher probability of being overweight/obese. In conclusion, the results suggest that a PB that influences PA and WS among youth may exist.pt_PT
dc.description.abstractEl objetivo fue determinar una barrera de competencia motriz (BC) para la actividad física (AF), el tiempo sedentario (TS) y el estado ponderal (EP) en dos etapas. En la Etapa 1, los valores de corte del cociente motor (QM), basados en la prueba KTK, para diferenciar el sobrepeso/obesidad del peso normal y el sedentario del no sedentario se identificaron en 734 participantes (353 niñas) de 10 años. En la Etapa 2, los valores de corte se usaron para definir grupos de QM bajo y alto (respectivamente por debajo y por encima de la BC) entre 217 jóvenes (118 niñas) de 12,9(0,4) años. El EP, la AF y el TS en los dos grupos de QM se compararon al inicio y 1,5 años después. Chi-cuadrado se usó para evaluar la independencia de la clasificación de QM bajo y alto en el EP, AF moderada-vigorosa (AFMV) y TS. Se calcularon los odds-ration de tener sobrepeso/obesidad y sedentarismo según el QM al inicio. Los QM de 79 para niñas y 75 para niños se definieron como la BC. En las niñas, la BC predijo clasificaciones significativamente diferentes del EP y una combinación de EP y AFMV. En los niños, la BC predijo clasificaciones significativamente diferentes en función del EP y AFMV combinados al inicio del estudio. Tener un QM por debajo de la BC se asoció con una probabilidad 2,78 mayor de tener sobrepeso/obesidad. En conclusión, los resultados sugieren que puede existir una BC que influye en la AF y el EP.pt_PT
