Explosive-Strength in Sub-12 Soccer. Theoretical Influence on Distance and Effectiveness in Throw-ins

Abstract

Introduction: Explosive-strength training is usually a determining indicator in many sports. Various researches that highlight the importance of the work of the different manifestations of force, and its impact on physical and technical-tactical performance. Objective: To theoretically validate, through consultation with specialists, an explosive-strength training plan for the upper body oriented to effectiveness and distance of the throw-ins of sub-12 soccer players. Methods: Descriptive-analytical research of a correlative order, applying a questionnaire to 15 national specialists in two moments of the intervention proposal with explosive-strength exercises. Accordingly, the research go through three phases (Preliminary Diagnosis, Preparation and Proposal Theoretical Evaluation). Results: Averages were established in the post-test with qualitative values between “Regular” and “Good” (Ob: 3.1; Or: 3.2; A: 3.1; P: 2.3; V: 2.5; I: 2.3; E: 2.3 & EP: 2), increasing all means as part of the post-test with a rating between “Good” and “Very Good” (Ob: 3.9; Or: 4.1; A: 4.1; P: 3.3; V: 3.6; I: 3.5; E: 3.3 & EP: 3), with significant differences in all comparisons (Ob: p=0.016; Or: p=0.000; A: p=0.000; P: p=0.001; V: p=0.000: 2.3; E: p=0.000 & EP: p=0.000). Conclusions: The second moment of designing the intervention proposal with explosive-strength exercises for upper limbs applied to soccer in the sub-12 category, obtained higher qualifications, theoretically validating the intervention proposal in the eight indicators studied.
