PLIOMETRIC EXERCICES FOR THE DEVELOPMENT OF EXPLOSIVE FORCE IN JUMPERS OF LONGITUDE

Abstract

The purpose of this investigation was to apply of |pliométrico| drills; concretely leaps in |contramovimiento| proposed by Verkhoshansky (1999), in three (3) jumping of longitude of the category 14-15 years in the sport of athletics of the school of sport initiation escolar EIDE “Pedro Diaz Coello†of Holguín. The of drills had a duration of sixteen (6) weeks of the stage of physical special preparation in which it is executed a series of |pliometricos| leaps. carried out a pre, test by means of a methodology proposed by Bosco (1994), composite for a shoe shop of four it tastes (Squat Jump, Counter Movement Jump, Abalakow and Drop Jump), these itself it is executed in a platform of contact called AxonJump, the who served to value and compare with a post, test, by registering the following parameters: explosive force, elastic manifestation – explosive of the muscles, elasticity index, index of use of hands, reflex manifestation explosive knit undershirt, quality coefficient and reactive capacitance. The results of the same thing permitted, that the system of |pliometricos| drills of leaps in the test of |contramovimiento| contributes to improve these manifestations of the force.
Key words. Exercises Pliometricos for jumps in against movements
