Análisis biomecánico de la carrera y el salto en niños de segundo grado de la enseñanza primaria Mariesly Guerra Hernández, José Rodolfo López Alonso Abstract: The research was based on the execution of a two-dimensional (2D) study of the biomechanical characteristics that determine the effectiveness of running and jumping in second-grade children at Eduardo Pérez Sánchez School in Las Tunas province. It follows a qualitative approach supported by analytical methods and videographic techniques using Kinovea 0.9.5 software. The study employed theoretical and empirical methods, including analysis-synthesis, inductive-deductive reasoning, and measurement. The obtained results revealed limitations in the teaching and learning process of these locomotor skills, which contribute to the establishment of incorrect movement patterns. The primary deficiencies were identified in the foot-heel impact during running and pelvic retroversion during vertical jumping. Key...

Optimización del desempeño en combate de Taekwondo mediante el uso de principios geométricos Autores: Idelgradis Batista Osorio, Jorge Paz Rodríguez Revista Pensar y Crecer (Copyright 2024 / ISSN: 2815-6560) ABSTRACT The objective of investigation concretizes in the logical integration of the geometry in the teaching of techniques of the sports of combat taekwondo and his contributions in the school space itself, bearing in mind the linkage of the mathematics with application to the physical activity and sports. The results obtained in the practical observation and of the revision of several bibliographies referred with the aforementioned teaching, metodológicas demonstrate the need to present suggestions that they contribute to a bigger efficiency in learning and the dynamics of combat, that permits that the geometry's foundations constitute fundamental tools that the efficiency in learning and the taekwondo's competition guarantee, held in a sig...

La teoría del caos como fundamento para una educación personalizada Autores: Pedro Menandro Calzado Vargas, María Ángeles Rodríguez Domínguez, María Marcela E. Rodríguez Domínguez Abstract: Chaos theory is a scientific approach that studies complex, dynamic and unpredictable systems. The aim of this article is to argue that chaos theory can help to understand the teaching-learning process as a complex, dynamic and unpredictable system. Based on this premise, a way of understanding and addressing personalized education in students and athletes is proposed. An education that recognizes the complexity of the learning process and that is based on flexibility, adaptation and creativity. Resumen: La teoría del caos es un enfoque científico que estudia los sistemas complejos, dinámicos e impredecibles. El objetivo de este artículo es sostener que la teoría del caos puede ayudar a entender el proceso de enseñanza-aprendizaje como un sistema complejo, dinámico e i...

Email: yaloddeokanire@gmail.com ABSTRACT The objective of this literature review is to evaluate the photochemical effect of the λ = 808 nm laser on the recovery of shoulder connective tissue. An exhaustive search of scientific articles was carried out in electronic databases, where those studies that investigated the effect of the λ = 808 nm laser on the regeneration of connective tissue were selected. The results of the reviewed studies indicate that the laser can promote collagen synthesi...
