Objective: To verify the validity and reliability of the scale of self-perception of physical aptitude EAF and to propose references 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 calculated. 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 generated 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 <0.001). Cronbach’s alpha showed values greater than 0.75. The percentiles proposed were P15, p50, p85.

Conclusion: The AAF scale is valid and reliable for university students. The percentiles are an alternative to identify, classify and categorize levels of physical fitness.
