Combined Training of Plyometric-Speed for Enhancing Home First-Base Race of Baseball Players, Junior Category

Abstract

In the last seasons the junior baseball teams of Matanzas have shown poor effectiveness in the run of the bases, having speed a determining factor in the game and therefore essential to achieve success in a baseball game. The objective of this research is to design a combined plyometric-speed training to enhance the run to first base home in baseball junior category players. To do this, a training program is applied based on the combination of plyometric and speed exercises dosed in three stages: first, general strength and low intense plyometric exercises, then, the introduction of moderate intensity plyometrics, and finally, the combined work of plyometrics of moderate-high and high intensity with speed exercises. The sample studied was composed of ten junior players, who participated in the XLVI Cuban Baseball National Championship. Three measurements were taken: first, at the end of the anatomical adaptation phase, then at the end of the muscular hypertrophy phase and the beginning of the intramuscular coordination-maximal strength combined with explosive strength and finally in the special preparation stage. To analyze the effectiveness of the exercises proposed in the time of the first home base race and in the reaction time, analysis of variance is applied, with a level of significance equal to 0.05. It is shown that there are significant differences in the time taken in the test that included the home first base racing, between each of the moments of preparation that were made, with a decrease of 4.40%. Meanwhile, in the first base home test hitting the hand with which the player batted and the moments in which controls were made influenced in the home first base time, showing a decrease of 3.38% in the effectiveness of the first base home race between the controls and a 3, 31% in the left-handed players in relation to the right-handers. On the other hand, in the test with a medical ball of 3kg with rotational movement and homefirst base race, a decrease in the time of effectiveness of 6.33% is reflected In the study, it is confirmed that there is a decrease in times with medical ball throwing (3kg) with rotational movement and home first base with a decrease in the effectiveness of 3.19% between the initial and final control.

“…Suspensión o denominado TRX (Total-body Resistance Exercise), según (Bompa & Buzzichelli citado por García-Ponce- de-León, et al 2019). expresan "se orienta al accionar de los músculos sin utilización de carga adicional, se favorece el ejercicio con el volumen corporal".…”
