Resumen
AVILA AVILA, Rafael M.; FREYRE VAZQUEZ, Francisco y WILSON WILLIAM, Luis. Post-Impact Bat Speed in Holguin Baseball Team. Ciencia y Deporte [online]. 2023, vol.8, n.3, pp. 459-474. Epub 11-Sep-2023. ISSN 2223-1773. http://dx.doi.org/10.34982/2223.1773.2023.v8.no3.011.
Introduction:
Post-impact ball speed is one of the most important metrics in baseball; however, in Cuba, the women's baseball has not conducted studies in this area. In the training of the first-category women baseball players in Holguin, for the Eastern Tournament, 2021, this issue was examined.
Aim:
To determine the relation between swing power and post-impact speed and between them and the batting average recorded in training matches.
Materials and methods:
Speed measurements and swing time were performed using a batting tee and a Sony speed gun.
Results:
Two simple physical-mathematical models were used to estimate the trajectory of the ball hit and swing power, and a set of weight exercises was designed to increase explosive strength.
Conclusions:
The regression and correlation methods permitted the estimation of the adjustment of a functional-linear ratio, the existence of a positive correlation between swing power and exit speed, and a much stronger linear correlation of the same sign between the batting average and the exit speed and batting average, and swing power, following the implementation of the exercise set.
