The main purpose of this study was the creation and validation of a system of assessment of the functional asymmetry of the lower limbs in Football game situation (SAFALL-FOOT). The evaluation develops throughout a 5x5 game situation, twenty minutes long, allowing the coding of the technical actions performed by each player into the 6 categories and 32 subcategories that compose the SAFALL-FOOT, and the calculation of an index of utilization of the preferred and non-preferred feet.

The content validity of the observation categories was established by a panel of experts composed of highly experienced coaches, former professional players, and university experts in the areas of Football and Motor Learning. The face validity was established by the evaluation of the players and coaches of the teams submitted to the test. The ecological validity resulted from the recognition of the congruence between Football game situation and the tasks of the test. The reliability of the instrument was ensured by the test-retest method, involving 80 players divided into teams of under-11 to under-19 (intraclass correlation coefficient: .97 for the preferred foot and .95 for the non-preferred foot). The intra-observer reliability attained high values of Kappa coefficient (>.80) in all the categories of the instrument. In summary, the results suggest that SAFALL-FOOT is a valid, reliable and appropriate system to assess the functional asymmetry of the lower limbs in Football game situation. KEY WORDS: Football.

Validation. 79-RPCD 12 (3) 04 INTRODUÇÃO O Futebol é uma modalidade em que o contexto de prática se estabelece num ambiente em permanente mudança, exigindo dos seus jogadores elevados níveis de adaptação que decorrem da interrelação de três tipos de capacidades: a cognitiva, a percetiva e a motora (6) . A capacidade cognitiva está relacionada com a competência que os jogadores evidenciam para perceber e compreender o que se passa no jogo (57, 58) . Isto é, num contexto em permanente mudança, o jogador, para tomar decisões ajustadas, necessita de ter em conta vários tipos de informação, relacionados com a sua posição no campo, com a localização da bola, com o posicionamento dos seus colegas e dos adversários, com as ideias da equipa e com as suas competências técnicas (57) . A capacidade percetiva, segundo Williams (57) , é uma das características que diferen-
