Plyometric Work Together With the Use of Ballast Weight in Lower Limbs in the Improvement of Performance in Jumpers

"Jump Drop Jump, dropping the subject from a height of 30cm and then make a vertical jump.~Long jumps asking the athletes to take momentum and make a leap forward trying to reach the greatest possible distance.~Jump Countermovement jump unilaterally, alternating the lower extremities. Jumps 180º with the athletes maintaining a semi-squat position. Jump Countermovement jump repeatedly starting from an upright position and the upper extremities in both hips.~All the exercises will be done through 8 repetitions per session during the first two weeks, increasing two repetitions every two weeks (until reaching 12 repetitions at the end of the intervention).~For the realization of each one of the exercises, the ballasted weight will be used (Powerinstep® model)."
