Summary: | <p align="justify">The purpose of this study was to determine the effectiveness of four traditional motor games (&ldquo;the tunnel&rdquo;, &ldquo;the chicken battle&rdquo;, &ldquo;the drunk&rdquo; and &ldquo;the wheelbarrow race&rdquo;) for strengthening the abdominal muscles. Electromyography (EMG) was collected from rectus abdominis (RA), external oblique (EO), and internal oblique (IO) from twelve healthy volunteers during the performance of the games and the trunk curl-up exercise. The EMG amplitude was averaged and normalized using maximal voluntary isometric contractions. A two-way ANOVA (muscle / task) was used to compare the level of contraction activity and the way the abdominal muscles co-activated during the different tasks. For EO and IO, the EMG amplitudes during the games were equal or greater than the EMG amplitudes of the curl up. The wheelbarrow race produced the highest intensity of contraction for all muscles. The curl up principally activated RA and IO. On the other hand, the games activated the oblique muscles with higher intensity than RA. On the basis of these results, the motor games are effective for abdominal conditioning. <br />KEY WORDS: motor<strong> </strong>games, exercises, training, abdominal muscles, electromyography.</p><br><p>&nbsp;</p><p class="resumenyabstract">El objetivo de este estudio fue determinar la eficacia de cuatro juegos motores (&ldquo;el t&uacute;nel&rdquo;, &ldquo;la pelea de gallinas&rdquo;, &ldquo;el tentetieso&rdquo; y &ldquo;la carretilla&rdquo;) para el fortalecimiento de los m&uacute;sculos del abdomen. Para ello, se registr&oacute; la electromiograf&iacute;a de los m&uacute;sculos rectus (RA), obliquus externus (OE) y obliquus internus abdominis (OI) de 12 voluntarios sanos durante la ejecuci&oacute;n de los juegos y del ejercicio de encorvamiento del tronco. La amplitud electromiogr&aacute;fica fue promediada y normalizada respecto a la contracci&oacute;n voluntaria isom&eacute;trica m&aacute;xima. Posteriormente, se realiz&oacute; un ANOVA de dos factores (m&uacute;sculo / tarea) para comparar la intensidad de la activaci&oacute;n muscular y la coactivaci&oacute;n de los m&uacute;sculos del abdomen entre las diferentes tareas. Los juegos motores produjeron niveles de actividad el&eacute;ctrica iguales o superiores a los obtenidos por el encorvamiento del tronco en los m&uacute;sculos OE y OI. La carretilla fue la tarea que gener&oacute; las intensidades de contracci&oacute;n m&aacute;s elevadas en todos los m&uacute;sculos analizados. El encorvamiento del tronco activ&oacute; principalmente los m&uacute;sculos RA y OI. Por el contrario, los juegos activaron con mayor intensidad los m&uacute;sculos oblicuos. Seg&uacute;n estos resultados, los juegos referidos son tareas eficaces para el acondicionamiento de la musculatura abdominal.<br />PALABRAS CLAVE: juegos motores, ejercicios, entrenamiento, m&uacute;sculos abdominales, electromiograf&iacute;a.</p> |
