Influence of physical speed capacity on jumping power in volleyball, school category/Influencia de la capacidad física de velocidad en la potencia de salto del voleibol escolar

Abstract

Integrated training demonstrates the need to implement various components of preparation to achieve higher performance. The importance of the plyometric method to enhance jumping ability is known, but other capacity such as speed could have a direct or indirect influence. In this sense, the objective is to determine whether the physical capacity for speed influences the jumping power of the school-class volleyball player. Quasi-experimental research of a correlative order that study the population of volleyball players from the "La Salle" Educational Unit, (Experimental Group 1: 26 students) and the "Oswaldo Lombeyda" Educational Unit (Control Group 2: 25 students), male gender, category 13-14 years. The groups underwent the same training, except that in the experimental group it was implemented a work strategy with physical stimuli, prioritizing speed loads for lower limbs. The means in jumping ability were significantly increased for the related samples (p = 0.000) in both groups (Group 1: 4.38cm to 6.23cm; Group 2: 4.40cm to 6.04cm) as part of posttest, there were no differences between independent groups (Pretest: k = 0.894; Posttest: k = 0.605), while the speed capacity for related groups increased significantly (p = 0.000) in posttest favor, there were no pretest differences (k = 0.183), with differences in the posttest in favor of the experimental group (k = 0.009). It is demonstrated a potentiation of the school volleyball player's jump, given the application of the plyometric method, repetition method and performance assessment test.
