Autopercepción de la aptitud física y propuesta de percentiles para su valoración en universitarios

espanolObjetivo : Verificar la validez y confiabilidad de la escala de auto-percepcion de la aptitud fisica EAF y proponer referencias por medio de percentiles en funcion del rango de edad y sexo Metodos : Se estudiaron 1569 jovenes (875 hombres y 694 mujeres) de una universidad del Peru. Se evaluo peso y estatura y se calculo el indice de Masa Corporal (IMC). La aptitud fisica se evaluo mediante la escala EAF. La validacion se efectuo por medio de Analisis Factorial Confirmatorio (A-FC). La confiabilidad se verifico por medio de Alpha de Cronbach y se generaron percentiles para la categorizacion. Resultados : La escala evidencio saturaciones superiores a 0,41 para 18 preguntas, el porcentaje de explicacion de la varianza fue del 52%, el KMO fue de 0,911 (X2 = 15578.883, gl= 435, p Conclusion : La escala de AAF es valida y confiable para jovenes universitarios. Los percentiles son una alternativa para identificar, clasificar y categorizar los niveles de aptitud fisica EnglishObjective: To verify the validity and reliability of the scale of self-perception of physical aptitude EAF and to propose ref - erences by means of percentiles in function of the rank of age and sex Methods: 1569 young people (875 men and 694 women) from a university in Peru were studied. Weight and height were assessed and the Body Mass Index (BMI) was calcu - lated. The physical aptitude was evaluated using the AAF scale. The validation was carried out by means of Confirmatory Factorial Analysis (A-FC). Reliability was verified by means of Cronbach’s Alpha and percentiles were gener - ated for categorization. Results: The scale showed saturations greater than 0.41 for 18 questions, the percentage explanation of the variance was 52%, the KMO was 0.911 (X2 = 15578.883, gl = 435, p The percentiles proposed were P15, p50, p85. Conclusion: The AAF scale is valid and reliable for univer - sity students. The percentiles are an alternative to identify, classify and categorize levels of physical fitness
