El test de 20 metros ida y vuelta. Revisión sistemática de su aplicación en personas con discapacidad intelectual / The 20 metres shuttle run test. Sistematic review of its application to persons with intelectual disability

Objetivo: El presente estudio realiza una revisión sistemática de la prueba de 20 metros ida y vuelta con el fin de conocer su validez y fiabilidad, y analizar las condiciones de aplicación de la prueba en personas con discapacidad intelectual (DI), con y sin síndrome de Down (SD). Método: Se llevó a cabo una revisión bibliográfica en cuatro bases de datos (Sport Discus, Psycinfo, Pubmed y Medline) utilizando un mismo patrón de búsqueda en cada una de ellas. Se incluyeron estudios desde 1990 hasta 2012, inclusive. Resultados: Un total de ocho artículos reunieron los criterios de inclusión. De los ocho artículos analizados, tres de ellos demostraron la validez de la prueba y cinco de los ocho fueron fiables. Los dos estudios con personas con SD no fueron válidos. En todos los estudios se hace mención a unas determinadas condiciones de uso del test. Conclusiones: Los resultados de esta revisión mostraron que las fórmulas utilizadas hasta el momento para predecir el consumo máximo de oxígeno (VO2max) en personas con SD no son válidas, por lo que se requieren nuevos estudios que analicen la validez de la prueba de 20 metros ida y vuelta en personas SD. Para que el test sea válido en personas con DI en general, requiere de una serie de adaptaciones en el uso del test. La familiarización con la prueba y la inclusión de un asistente es necesario (AU)

Objetive: The current study carries out a systematic review of the 20 metres shuttle run test to know the validity and reliability of the test and analyze the application conditions in persons with intellectual disability (ID) with and without Down syndrome (DS).Method: A bibliographic review has been made using four data bases (Sport Discus, Psycinfo, Pubmed and Medline) with the same search pattern in each one, from 1990 until 2012, both included. Results: A total of eight articles met the inclusion criteria. Three articles were considered valid. Five of the eight studies were reliable. The two studies which tried to analyze validity in Down syndrome showed not to be valid. All studies mentioned specific conditions to perform de test in this collective. Conclusions: Results of the review showed that the equations used to predict maximum oxygen uptake (VO2max) in persons with DS are not valid. Therefore, new studies are required to analyze the validity of the 20 metres shuttle run test in persons with DS. In order to get validity in individuals with ID it is necessary to adapt the test, adding a familiarization process with the test and one assistant performing it together with the participants (AU)

Reliability of the ALPHA health-related fitness test battery in adolescents with Down syndrome.

The Assessing Levels of Physical Activity (ALPHA) health-related fitness test battery is a set of reliable, valid, and feasible tests to assess health-related physical fitness in children and in adolescents. The aim of this study was to examine the reliability of this battery in adolescents with Down syndrome (DS). The extended ALPHA health-related fitness test battery was performed twice within 1 month in 17 apparently healthy adolescents, aged 12-18 years, with DS who had an intelligence quotient ≥ 35. Intraclass correlation coefficient (ICC) was used to determinate test-retest reliability, and nonparametric Wilcoxon signed rank test was used to compare mean differences between measurements. With the exception of subscapular skinfold test, which obtained a moderate agreement (ICC = 0.64), all tests had a very high reliability: the 20-m shuttle-run test (ICC = 0.86), the right handgrip strength test (ICC = 0.86), the left handgrip strength test (ICC = 0.86), the standing broad jump test (ICC = 0.85), body mass index (ICC = 0.95), waist circumference (ICC = 0.98), triceps skinfold (ICC = 0.85), and the 4 × 10-m shuttle-run test (ICC = 0.92). There were no significant differences (all p > 0.05) in any of the tests. The ALPHA health-related fitness battery is reliable for measuring health-related components of fitness in adolescents with DS.
