ANÁLISIS MATEMÁTICO Y BIOMECÁNICO DE LA FIGURA FRONT LEVER EN STREET WORKOUT

Abstract

This study focuses on the biomechanical analysis and calculation of forces involved in the front lever figure, an advanced posture in Street Workout, which requires significant control of isometric strength and body alignment. Through a rigid body model, the forces and torques required to maintain the horizontal position of the body were evaluated, determining the importance of the center of mass, moment of inertia and reaction force in the hands. The analysis showed that maintaining the front lever involves a torque of 588.6 N and a force of 1051 N applied by the arms, which underlines the isometric force demands to counteract gravity and stabilize the posture. The results provide information on specific muscle activation and load management in advanced isometric exercises, which may have implications for the optimization of training programs and injury prevention in disciplines that require high levels of muscle control. These findings may also contribute to the development of formal regulations and evaluation criteria in competitions, providing a basis for objective assessments in Street Workout and other isometric strength sports.
