Resumen
La mayoría de las lesiones en el Voleibol están asociadas al momento de
aterrizar del salto, produciéndose lesiones por inversión del tobillo. Se ha observado
que luego de programas de entrenamiento neuromuscular para la extremidad inferior
disminuyen los tiempos de activación de la musculatura estabilizadora de tobillo.
El objetivo de este estudio es asociar el efecto de un calentamiento
neuromuscular en el equilibrio dinámico y el tiempo de activación de Tibial Anterior
y Fibular Largo de tobillo dominante en el seleccionado de varones de Voleibol de la
UNAB.
Este es un estudio experimental no controlado de tipo analítico, donde
participaron 7 sujetos sanos, a los cuales se les aplicó un calentamiento
neuromuscular de 4 semanas y se les realizaron mediciones pre y post calentamiento
en EMG y SEBT
Para el estudio del tiempo de activación de la musculatura, no se encontraron
diferencias estadísticamente significativas en los músculos Tibial Anterior y Fibular
Largo luego de la intervención. En cuanto al equilibrio dinámico encontramos
diferencias significativas en 2 de las 3 direcciones evaluadas, dirección Anterior (p=
0.0469 y la diferencia de la mediana=9) y en la dirección Posterolateral derecha
(p=0.0313 y la diferencia de la mediana=5.5).
Luego de un protocolo de 4 semanas de Entrenamiento neuromuscular no
disminuye significativamente el tiempo de activación de la musculatura de tobillo.
Con los resultados obtenidos en el SEBT podemos afirmar que sí existen
cambios significativos en la medición del equilibrio dinámico.
Most of injuries in Volleyball practice are associated to the moment of the landing after a jump, creating injuries due to the inversion of the ankle. It has been observed that after neuromuscular training programs on the lower limbs, the activation time of the ankle’s Stabilizing Muscles was decreased. The aim of this study is to describe the impact generated by neuromuscular warming in the time of the activation of the Tibialis Anterior and Fibularis Longus muscles of the dominant ankle and the dynamic equilibrium of the players of the UNAB Volleyball team. This is an experimental non-controlled analytic type of study in which seven healthy people went through a Neuromuscular warming (program) of 4 weeks and, they were measured before and after the warming with EMG and SEBT In the study about the muscle activation time, it was found that for the Tibialis Anterior and Fibularis Longus muscles there were not significant differences after the intervention. As for the Dynamic equilibrium there were found significant changes in 2 of the 3 evaluated directions, Anterior direction (p= 0.0469 whit media difference=9) and post-lateral direction (p=0.0313 whit media difference=5.5). After a neuromuscular warming protocol, no significant improvement was found in the reduction of time of muscle activation. Nevertheless, an improvement was found in the range of time of the activation of the evaluated muscles. With the results obtained in the SEBT we can state that significant changes do exist in the measuring of Dynamic Equilibrium.
