UTILIZACIÓN DEL VÍDEO PARA LA MEJORA DE LA PERCEPCIÓN SUBJETIVA DE LA EFICACIA COMPETITIVA Y DEL RENDIMIENTO EN JUGADORES DE BALONCESTO.

This study assesses how the application of an intervention program involving the use of video improves basketball players' real perception of their actions when competing and boosts their performance levels. A three-month intervention program was designed and applied that consisted of watching videos of games in which the degree of efficacy of each player's proposed objectives were evaluated. The following were recorded for four months before the intervention program was applied and during its development: a) the outcome of each player's individual objectives and minutes played; b) the subjective perception of the outcome of these objectives and minutes played; and c) the difference between what actually took place and what was perceived, as well as between the minutes played and minutes perceived to have been played. The results indicate an improvement in the players' real perception of their actions in games after the intervention program; in terms of efficacy, the percentage of positive actions rose and the percentage of negative actions fell. These data indicate that watching videos of actions in games improves players' perception of reality, which leads to a better grasp of negative and positive actions, a key aspect of intervening in practice sessions. This, in turn, boosts both individual and collective performance. [ABSTRACT FROM AUTHOR]
