CRESPO MADERA, Elio Jesús; COSTA ACOSTA, Jesús  y  VALDEZ LOPEZ PORTILL, Manuel Rafael. Physical foundations of the pitcher's technical gesture. Rev Podium [online]. 2021, vol.16, n.2, pp.332-344.  Epub 01-Ago-2021. ISSN 1996-2452.

The greed to throw hard in baseball, plus the mechanical-energetic ignorance of the contribution and what prevents the correct execution of the phases of the pitcher's technical gesture, turned out to be the main causes of injuries and the reason for an explanatory research, through the application of physical kinematic, dynamic and energetic methods, in the study of the manifestation of physical laws during the non-participatory observation of their performance, when throwing the ball, both in national and international pitchers and testimonies of people with experiences as pitchers. The objective of this article is to propose a physical explanation of how the biomechanics of the pitcher's body works during the technical gestures of pitching to guarantee a fast ball and minimize injuries. With this work, it is also intended to instruct the pitcher on how the biomechanics of his body works during the pitching of the ball, taking advantage of the height of the mound with arguments from the physical science. This contributes to faster, more elegant pitches and to minimize injuries. As a result, a physical explanation by phases was elaborated for the pitcher, in addition, an isolated mass-spring system to experiment biomechanical and energetic movements, which evidenced in their performance manifestations of the physical laws of Newton's classical mechanics, conservation of mechanical energy, kinetic momentum and angular momentum.
