Abstract
Background: The back saver sit and reach (BSSR) test is probably the most frequently quantitative tool used to estimate hamstring flexibility in the school and physical-sporting field due to its simplicity and quickly implementation. However, there is limited scientific evidence to justify its use in colombian girls. Objective: To assess the validity and intra-rater reliability of the BSSR in girls of a school from Bucaramanga. Mathodology: A study of evaluation of diagnostic technology was done in 64 girls (7-8 years), selected by convenience. BSSR test and straight leg raising test (SLRT) were conducted on two consecutive occasions by the same researchers. It was calculed the Pearson (r) or intraclass (ICC) correlation coefficient with their respective confidence intervals (95% CI 95%). Results: The global validity was good (r=0.61 (95% CI 0.43-0.75) – r=0.66 (95% CI 0.49-0.78)), while intra-rater reliability was very good in the left lower limb [ICC= 0.90 (95% CI 0.67 to 0.96)] and right lower limb [ICC = 0.88 (95% CI 0.63 to 0.95)]. Conclusion: BSSR test has good reliability and validity for assessing lower limb flexibility in girls aged 7 to 8 years.

Summary
Validez y reproducibilidad de la prueba Back-Saver Sit and Reach en niñas de 7 y 8 años. Introducción: La prueba de valoración back saver sit and reach BSSR es probablemente una de las herramientas cuantitativa de estimación de la flexibilidad isquiotibial que con mayor frecuencia emplean en el ámbito escolar y físico-deportivo, por su sencillez y rapidez en su proceso de administración. Objetivo: evaluar la validez y reproducibilidad intraevaluador de la prueba BSSR en niñas de una institución educativa de Bucaramanga. Se realizaron las pruebas BSSR y el test de elevación de la pierna recta (TEPR) en dos oportunidades consecutivas por los mismos evaluadores. Conclusión: la prueba BSSR tiene adecuada reproducibilidad y validez para evaluar flexibilidad de miembros inferiores en niñas de 7 y 8 años. Palabras clave: validez de las pruebas; reproducibilidad de resultados; niño; rango del movimiento articular.
