Improving the technical performance of junior discus throwers during the delivery phase

Abstract:

Introduction: Sport technique implies the teaching-learning of specific observationally and biomechanically studied models or patterns which operate integrally in each sport gesture. Eminently technical training may improve sport performance in the short and medium terms. Objective: Evaluate the effects of the implementation of exercises aimed at the technical improvement of the delivery phase among junior discus throwers. Methods: Fifteen junior (16-17 year-old) female discus throwers were selected by intentional non-probabilistic sampling. Preliminary diagnosis essentially detected 12 basic technical movement errors in the delivery phase, leading to implementation of a training macrocycle (2017-2018) of exercises focusing on the nine discus throw phases. A discus throw test was applied at two moments along the training. Results: The highest average or mean was achieved as part of the post-test (30.33 m), with a throw distance increase of over 6 m in comparison with pre-test data (23.73 m), and significant differences (p= 0.000) when comparing the data obtained in the two diagnostic evaluations conducted. Conclusions: Sport training based on a mainly technical approach leads to sport preparation improvement by strengthening discus throw skills among junior throwers. The strategy implemented, based on specialized technical exercises applied during the study macrocycle (2017-2018), proved significantly useful to improve the technical performance of junior discus throwers during the delivery phase.
