ABSTRACT

Introduction: The angles study of launching in grenade of the military pentathlon makes it possible to know the forces and accelerations that prevail as part of action field in biomechanics, making it possible to establish the behavior of certain variables that performance influence. Objective: Biomechanical differences between beginner and high performance athletes are studied in the grenade launching test of the Military Pentathlon team of the Ecuadorian Armed Forces. Methods: The athlete population of the Ecuadorian Military Pentathlon team (13 subjects) is studied, dividing the group into beginner and high-performance athletes. We study the three phases in grenade launch, launch time, average speed and acceleration of the wrist joint, and gravity center. Results: The study determined the existence of lower angles in the studied variables in high-performance athletes with respect to beginners, some of them being significant, according to Mann-Whitney U-Test (p= 0.05). Conclusions: The minor angles detected in studied biomechanical variables present in high-performance athletes can be predictive indicators of future performance in initiation athletes.
