Study on the percentage of information accumulated by visual memory during a handball game and the necessity of observation sheets

Abstract

The aim of this study is to highlight the complexity and multitude of the information that comes to light, from the coaches’ capacity to memorise, on the one hand, and, on the other, from the notes on the observation sheets, regarding the game stages and the tactical individual and collective actions of an official handball game.
Regarding the capacity of memorising and of storage of the visual information during the competitions, there is the idea that this should be substituted by the use of observation sheets, fact that will ensure a correct and efficient analysis of the game.
