Laterality training in the technical and offensive fundamentals of U-12 soccer players. Theoretical validation/El entrenamiento de la lateralidad en los fundamentos técnicos-ofensivos de futbolistas sub-12. Validación teórica

Abstract

Laterality is considered as the functional domain of one side in the body over the other to carry out specific activities. In sport laterality is systematically enhanced, since the improvement of all body parts infers competitive advantages of high technical-tactical value. The objective of this research is to theoretically validate, through national and international experts, a proposal of laterality indicators to be taken into account in the training of the technical-offensive foundations of U-12 soccer players, evidencing the importance of each indicators in each group of independent experts. This is a theoretical-descriptive research of correlational order and qualitative analysis, intentionally selected 10 national experts (Ecuador) and 10 international experts (Spain and Italy) for the quantitative and qualitative determination of indicators that evaluate laterality. There are significant differences in indicator Visual Laterality (p = 0.000), Shoulder Laterality (p = 0.000), Waist Laterality (p = 0.000), Static Leg (p = 0.000), Director Foot (p = 0.043) and Non-director Foot (p = 0.000), while in the Dynamic Leg indicator there were no significant differences (p = 1.000) between independent groups. International experts comprehensively assess all the laterality indicators studied, providing a higher total score. Consequently, the need to carry out methodological work in national experts in order to improve understanding of laterality training importance in all its manifestations is evident.
