Abstract

The present research analyses the effect of the shout as a psychological ergogenic resource in the strength of people`s legs who practice Kung Fu using the long-distance jump test without impulse and the other called “Sargent” or high jump. Two groups were formed with n=8 eighteen and twenty -eight year old subjects each. The subjects from Group A or Control had to carry out the practices without shouting while the others from Group B or Experimental group had to shout as loud as possible during the practices. An Anova 2x3 and an analysis of simple effects for groups and measurements were applied to the results during the practices as well as a Tukey analysis. In this analysis a significant difference in the result of the long-distance jump without impulse with shout was found in comparison to the results obtained by group A or control that didn`t shout. In the high jump practice no significant difference was found between the obtained data (information) from groups B and A. However, a little improvement was shown in group B. This study, shows that the use of the shout as a psychological ergogenic resource might affect the strength of legs positively, mainly if it is used in the exact moment that a specific skill of this variable of performance is being carried out, that is “the jumps”.
