Resumen
El objetivo de este trabajo investigativo fue explicar y describir el efecto que tiene
un protocolo de entrenamiento pliométrico sobre la flexibilidad isquiosural, el
perímetro de muslo y el rendimiento en grupo experimental v/s grupo de control en
una prueba de medio fondo estilo crol en cadetes de la Escuela Naval de la región
de Valparaíso. Para ello, participaron 20 sujetos de género masculino, 12 de ellos
formaron parte del grupo experimental que realizó un protocolo de entrenamiento
pliométrico sumado a su entrenamiento de base, mientras que los 8 restantes
formaron parte del grupo control que realizó únicamente su entrenamiento de
base. Sin embargo, 2 participantes del grupo experimental no terminaron el
protocolo de entrenamiento por motivos de salud ajenos al estudio. El protocolo se
ejecutó durante 6 semanas con 2 entrenamientos semanales, en el cual se
realizaba el calentamiento, ejercicios pliométricos y la vuelta a la calma, todo
enfocado a miembro inferior. Los ejercicios abarcaban series de drop jumps,
desde cajones con alturas que aumentaban progresivamente cada 2 semanas y
saltos longitudinales.
El grupo experimental y el grupo control fueron elegidos por conveniencia. Ambos
grupos fueron sometidos a evaluaciones de flexibilidad isquiosural, perímetro de
muslo y rendimiento al principio y al final de la investigación. Concluyendo en base
a los resultados estadísticos, efectivamente existen cambios significativos post
entrenamiento pliométrico para la variable de flexibilidad en el grupo experimental
(P es igual a 0,0005). Para el perímetro de muslo, no existen cambios
significativos en ninguna de las comparaciones ya que todos los resultados de P
son mayores que 0.05. Finalmente, existen diferencias significativas post
entrenamiento para la variable de rendimiento en el grupo experimental. (P es
igual a 0,0206). Por lo tanto, los mayores cambios se encontraron en relación a la
variable de flexibilidad isquiosural y rendimiento en el grupo experimental tras ser
sometidos al entrenamiento pliométrico en adición al entrenamiento de base.
The objective of this research work was to explain and describe the effect of plyometric training protocol on hamstring flexibility, muscle circumference and performance in experimental group v/s a control group in a middle distance race in front crawl cadets from the Naval Academy in the region of Valparaíso. To do this, they involved 20 male subjects, 12 of them were part of the experimental group performed a protocol plyometric training added to their training base, while the remaining 8 were part of the control performed only his basic training group. However, 2 experimental group participants did not complete the training protocol due to health reasons unrelated to study. The protocol was run for 6 weeks with 2 weekly trainings, in which warm-ups, stretching, and plyometric exercises were conducted focusing on the lower limbs. The latter spanned longitudinal series of jumps and drop jumps from heights drawers progressively increased every 2 weeks. The experimental group and the control group were chosen by convenience. Both groups were assessed with hamstring flexibility, thigh girth and performance at the beginning and end of the investigation. In conclusion based on the statistical results, there are significant changes before and after to the plyometric training for flexibility variable in the experimental group (P equals 0.0005). For thigh circumference, there were no significant changes in either comparison results since all of P is greater than 0.05. Finally, there are significant differences for the variable performance before and after to the training base + plyometric training protocol for the experimental group (P equals 0.0206). Therefore, major changes were found in relation to the variable of hamstring flexibility and performance in the experimental group after being subjected to plyometric training in addition to the training base.
