Nuevas perspectivas metodológicas en validación de acelerómetros para estimar la Actividad Física de adultos en actividades cotidianas

Abstract

Actualmente el acelerómetro es la herramienta más práctica y fiable para cuantificar la actividad física. El problema es que los modelos de estimación obtenidos hasta el momento no han tenido en cuenta la inclusión de los minutos de transición entre actividades, el desfase entre las aceleraciones y METs, y las variables del dominio temporal, frecuencial y de la estructura temporal de la señal. El objetivo de este estudio descriptivo transversal fue comprobar estos factores para la obtención de un modelo de estimación. Para ello, se reclutaron 30 sujetos con 55,5 (9,42) años, 73,03 (11,84) kg y 1,70 (0,08) m. Estos realizaron una serie actividades cuotidianas equipados con un acelerómetro Actigraph GT3X y un analizador de gases. Mediante el análisis de estos factores se obtuvo un modelo lineal múltiple más fiable que los modelos lineales obtenidos previamente para el acelerómetro Actigraph GT3X. Estos resultados mostraron la necesidad de incluir en los modelos lineales múltiples los minutos de transición entre actividades y las variables temporales, frecuenciales y aquellas que informan sobre la estructura temporal de la señal. En cambio, el desfase entre las aceleraciones y los METs disminuyó la exactitud de los modelos.
