Os batedores (N=24) pertencentes à Série Nacional de basebol LIX foram escolhidos porque constitui o evento nacional de mais alto nível do basebol cubano. A informação foi registada durante o treino de batedores, enquanto o batedor executava a tarefa de ligar bolas lançadas pelo treinador a partir do lançamento frontal, sobre o braço a uma distância de 30 pés e a uma velocidade inferior a 50 mph. Os resultados do Blast Motion Baseball foram então comparados com as estatísticas oficiais da Série Nacional de Basebol LIX. Foi demonstrado que batedores com maiores velocidades de taco, maiores velocidades de mão superior, e mais potência alcançaram um maior desempenho ofensivo. Portanto, conhecer estas características do balanço em tempo real ajuda a refinar o processo de treino e a prever o desempenho atlético de um batedor.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The introduction of new technologies in baseball has optimized the systems for recording and analyzing information, both in training and in the game, contributing to a more accurate control of a player's performance. In this work, it is applied the Blast Motion Baseball sensor which objective is to identify the variables significantly influencing the performance of batters in Cuban baseball. There were chosen batters (N=24) belonging to the National Baseball Series LIX because it constitutes the national event of higher level in Cuban baseball. The information was recorded during batting practice, while the batter was performing the task of connecting balls thrown by the coach from the front toss, over the arm at a distance of 30 feet and at a speed of less than 50 mph. The results of Blast Motion Baseball were then compared with the official statistics of the LIX National Baseball Series. It was shown that batters with higher bat speed, higher top hand speed and more power achieved greater offensive performance. Therefore, knowing these characteristics of the swing in real time helps to perfect the training process and predict the sports performance of a batter.]]></p></abstract>
