El análisis de la influencia del tiempo de juego y la puntuación parcial sobre el comportamiento táctico en el ataque en balonmano, utilizando la técnica de coordenadas polares

Abstract

<p><span style="font-size: medium;">Different studies have referred that the playing time and partial score, as well as the interaction between these two influences the behaviors of players and teams. With this study we intended to realize the complex reality of tactical behavior in the attack in Men´s European Cup, by detecting behavior patterns and linking them to playing time and partial score.</span></p><p><span style="font-size: medium;">We used the observational methodology and for data analysis we used the polar coordinates. An instrument of observation has been constructed <em>ad hoc</em> and validated. The tool optimization included the quality data control, using the analysis of intra and inter observer reliability by Cohen's Kappa index (range between .85 and 1), beyond the application of generalizability analysis (G indexes are suitable for all models estimated) confirming the instrument reliability. The sample contained all of 2<em>vs</em>2 situations that occurred during the organized offensive process in numerical equality 6<em>vs</em>6, in sixteen games (n = 390). </span></p><p><span style="font-size: medium;">As main results we can refer that the playing time influenced the decision-making in relation to the tactical means used, excepting the last ten minutes, where no patterns were found. The results also show that there are fewer behavior patterns when the score is a draw.</span></p>
