Pilates, Electromiografía, Ejercicios de Estiramiento MuscularResumen
El objetivo de este estudio fue evaluar el efecto del
cambio de la constante de la muelle en la actividad electromiográfica
(EMG) de los músculos del powerhouse y del hombro durante
el ejercicio de long stretch. En el estudio participaron quince
practicantes de pilates que realizaron el ejercicio long stretch en el
reformer con tres constantes elásticas: (1) k=0,19kg/cm, representado
por 1 muelle roja; (2) k=0,27kg/cm, representado por 1 muelle roja
y 1 muelle amarilla; y (3) k=0,38kg/cm, representado por 2 muelles
rojas. Se evaluaron las actividades EMG de los músculos recto
abdominal (RA), oblicuo externo (OE), oblicuo interno/transverso
(OI/TS), multífidos (MU), iliocostal (IC), longuissimus (LG), deltoides
anterior (DA) y trapecio inferior (TI). Se pudo observar que a medida
que aumenta la constante elástica de la muelle, los músculos RA,
OE, OI/TS disminuyen su actividad EMG, mientras que los músculos
DA, TI y LG aumentan su actividad EMG. Los músculos MU e IC no
fueron influenciados en sus actividades EMG. Se puede concluir
que hubo influencia del cambio en la constante elástica de la muelle
sobre la actividad EMG de los músculos RA, OE, OI/TS, LG, DA y TI
durante el long stretch, pero no hubo influencia en las actividades
EMG de los músculos MU e IC
