Resumen
Objetivo: El objetivo del estudio es identificar y analizar la influencia de la composición corporal y la tasa metabólica basal sobre el comportamiento de los parámetros temporales de las fuerzas reactivas del suelo durante la marcha postmenopáusica.
Métodos: El estudio experimental se realizó con 52 mujeres (± 59,8 años). La masa grasa, la adiposidad visceral abdominal, la masa muscular esquelética, la masa sin grasa y la tasa metabólica basal se han evaluado mediante bioimpedancia octopolar. Los datos de las fuerzas reactivas al suelo se recogieron a través de la plataforma de fuerza.
Resultados: En términos relativos, la masa grasa mostró influencia en la fase final de soporte, provocando una disminución en este parámetro. La adiposidad visceral abdominal también ejerció una influencia inversa sobre la carga vertical (r = -0,31) y la descarga (r = -0,35). La masa muscular esquelética (r = -0,45, r = -0,46; p <0,01) y la tasa metabólica basal (r = -0,44, r = -0,46; p <0,01) influyeron en la tasa de carga vertical y la relación entre las tasas verticales significativamente.
Conclusión: El estudio sugiere que el aumento de la masa grasa y la adiposidad abdominal visceral, influyen en el tiempo de soporte y las tasas verticales. Con un sistema de músculo esquelético más robusto, las mujeres posmenopáusicas exhiben las fases del ciclo de la marcha menos acentuadas, señalando menos tensión en las articulaciones.
