Evaluación de la eficacia de un programa de entrenamiento de velocistas en la mejora de la aceleración y velocidad de esprint en jóvenes futbolistas de la escuela de fútbol Gad Parroquial Javier Loyola

Abstract

This study addressed the knowledge gap on the effects of implementing an acceleration and sprinting program for sprinters in the context of soccer. Therefore, its impact on sprints during training was evaluated. A quantitative quasi-experimental design (no control group) was used with 56 youngsters from the Gad Parroquial Javier Loyola Soccer School. The adapted program was applied for 6 weeks, measuring the variables (5-0-5 agility test and 10x5 speed test) in pretest and posttest. To control possible biases, sports motivation (by means of a psychological survey), average BMI and the percentage of lean mass of the lower body were recorded before the intervention. The analysis evidenced significant changes in acceleration, speed and agility in both genders: 5-0-5 test (female Δ=0.61 s., male Δ=0.42 s.), 10x5 test (female Δ=1.02 s., male Δ=0.69 s.). It is concluded that individualization of training based on gender, physical profile and motivation not only enhances immediate performance, but also establishes bases for sustainable sports development in soccer academies.
