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.
