Influencia de dos tipos de calentamiento sobre la fuerza explosiva del tren inferior en estudiantes de Educación Física

Abstract

The aim of the present study was to determine the possible influences of two types of warm-up (traditional and specific) on the explosive strength of the lower train. Two tests were carried out (Counter Movement Jump -CMJand 5 meters sprint) in three groups: group not warm-up (GSC), traditional warm-up (GCT) which included articulated mobility, continuous running and static stretching; and specific warm-ups group (GCE) performed a articulated mobility, continuous running, dynamic stretching and plyometric exercises. A pre and post test was performed and ANOVA was used to compare the influence of the type of warm-up on tests and between groups. Subsequently the effect size was calculated through Hedges' g. The results showed statistically significant differences between the pre and post test in the GCT and in the GCE; furthermore, statistically significant differences (p <.05) were found in CMJ test between GSC and GCE, in the posttest. Performing dynamic stretching and plyometric exercises as part of the warm-ups seems to positively influence the ability to jump vertically. The data suggest that teachers of physical education should use warm-ups with dynamic stretching and plyometric exercises to enhance performance in activities that include jump.
