Technical perfection of the deep free return in swimmers between 11-12 years

Abstract

Introduction: Empowering models or technical standards integrally allows maximum efficiencies that influence athletic performance. Objective: To apply specific exercises to improve the technique of deep return for freestyle, correlated if the improvement of mentioned technique influences the displacement speed in water. Methods: The swimming population of the ESNAN Swimming Club (20 male subjects between 11-12 years old) is studied. A group of selected exercises was applied during six months (June-November 2017), applying an observational technical test evaluating six technical indicators before and after the exercises were implemented, as well as an evaluation of the time used to complete a 100 meters freestyle test in each month studied. Results: The score that evaluates the sports technique studied (Pretest: 1.5, Postest: 2.7) in the final test was increased, being significantly different (p=0.000), significantly decreasing the time used to complete the speed test in 100 meters of free swimming (p=0.000). Pearson's r moment corroborated a significant negative influence between the score obtained in the deep lap technique with the time used by the swimmers to complete the swim speed test in 100 meters freestyle (r = -0.806419105), which it increases as the score obtained in the deep return technique increases (Posttest: 2.7) to r = -0.888494065. Conclusions: The strategy significantly improved the speed of displacement in the water of the swimmer under study. On the other hand, an observational improvement was demonstrated in the deep return technique for freestyle, there being a significant inverse correlation between the score obtained to improve the technical movement and the time used to complete the 100 meters test, inferring that perfecting the deep lap technique decreases the time taken to complete the 100 meters test.
