“…In defensive terms, it was still possible to find Tpatterns related to the goal exit (Berto and Magalhães, 2017;Lapresa Ajamil et al, 2018), with the technical execution of 1×1 shot, 1×1 frontal attack, and 1×1 divided. The literature points out that these types of actions of the GKs are more evident in high-level teams (Szwarc et al, 2010;Filho et al, 2018), since the last defensive line plays very high, and the action of the GK is fundamental for depth control.…”

Nowadays, football goalkeepers (GKs) play an important role in the team's organization, namely, considering the offensive and defensive processes. The purpose of our investigation focuses on the notational and T-pattern analysis of the offensive and defensive actions of elite young football GKs. The participating GKs (n = 3, mean age of 16.6 years) presented 8 years of experience in the specific position, were internationally selected for the national team of Portugal, and competed in the national U-17 championship of Portugal. Thirty football matches were observed. The observational sample consisted of defensive actions (n = 225) and offensive actions (n = 296). Two observational instruments were used to codify the actions: the observation system of defensive technical-tactical actions of GKs and the observation system of offensive technical-tactical actions of GKs. Both instruments underwent a validation process, and inter- and intra-observer reliability was tested. The codification of the actions was performed with the LINCE program, and later the data were exported to Microsoft Excel and THEME 5.0. The notational data were analyzed in SPSS, and T-pattern detection analysis was performed in THEME 5.0. The predominant actions of young observed GKs were fundamentally goal defense and participation in the team's offensive process construction through actions performed with the foot and hand. The analysis of T-patterns allowed to identify T-pattern actions in the defensive actions of goal defense and exit of the goal, as well as related to the defensive set pieces. In the offensive process, the analysis of T-patterns reinforced the participation of the GK in the team's first phase of construction and in the execution of goal kicks and actions that start as a result of the actions of the opponent. The GK's defensive actions are mostly focused on the objective of goal defense and offensive actions with the hands and feet are important for their participation in positional attack construction. Our study contributes to a better knowledge of the GK's actions in the competition and is relevant to be considered by the specific position coaches in the training process organization.

El portero tiene un papel importante en el proceso ofensivo y defensivo de un equipo de fútbol. El objetivo del estudio era analizar las acciones ofensivas y defensivas de los GR U-17 del fútbol, utilizando la metodología observacional. GR Sub-17 (n=4) fue analizado en Se analizaron treinta partidos del campeonato del distrito de AF Lisboa. La muestra observacional consistió en 286 acciones defensivas y 790 acciones ofensivas. Utilizamos los sistemas de observación de las acciones técnico-tácticas ofensivas y defensivas de los porteros. Las acciones observadas fueron codificadas utilizando el programa informático LINCE versión 1.3. El procesamiento de datos se realizó a través de análisis descriptivos, de la prueba U-Mann Whitney para comparar las acciones en la condición de local y visitante y estadísticas gráficas. Verificamos en las acciones defensivas un mayor número de ocurrencias en forma de intervención fuera de gol (n=140; 4.66±2.57), acción como la última defensa (n=102; 3.4±2.34), forma de ejecución técnica con ambas manos (n= 205; 6,83±3,32) y zona final de la acción técnica 1 (n=155; 5,16±3,19). En las acciones ofensivas registramos más ocurrencias para la forma en que la pelota llegó al portero a través del retardo (n=263; 8.76±3.89), inicio de la acción en la zona 1(n=205; 13,30±4,72), patada de objetivo corto de acción técnica (n=191; 6,36±3,99), ataque posicional de decisión táctica (n=498; 16.60±5.87), fin de la acción de mantenimiento de la posesión (n=593; 19,76±5,81) y zona final de la acción 5 (n=131; 4,36±3,47). En el proceso defensivo, la acción del portero tiene una enorme preponderancia como la última defensa y defensa de la portería. En el proceso ofensivo, las acciones técnicas con los pies son relevantes en la participación en la construcción del ataque posicional. La acción de los porteros está influenciada por la condición del visitante. The goalkeeper (GK) has a major role in the offensive and defensive process of a soccer team. The aim of the study focused on the analysis of the offensive and defensive actions of the U-17 soccer GK, using observational methodology. U-17 GK (n=4) was analyzed in thirty Lisbon FA U-17 championship games. The observational sample consisted of 286 defensive actions and 790 offensive actions. We used the observational systems of the offensive and defensive technical-tactical GK’ actions. The actions observed were codified using the LINCE version 1.3 computer program. Data processing was performed through descriptive analysis, of the U-Mann Whitney test to compare actions in home and away condition and graphical statistics. We verified in the defensive actions a higher number of occurrences in the intervention form come off from goal (n=140; 4.66±2.57), action as last defender (n=102; 3.4±2,34), technical execution form with two hands (n= 205; 6.83±3.32) and final zone of technical action 1 (n=155; 5.16±3,19). In the offensive actions we recorded more occurrences for ball arrives the GK through back pass (n=263; 8.76±3.89), start of the action in zone 1 (n=205; 13.30±4.72), technical action short goal kick (n=191; 6.36±3.99), tactical decision positional attack (n=498; 16.60±5.87), final action maintenance of ball possession (n=593; 19.76±5.81) and final zone of action 5 (n=131; 4.36±3.47). In the defensive process, the action of the GKs has enormous preponderance in the action as the last defense and goal defense. In the offensive process, technical actions with the feet are relevant in the positional attack construction participation. The GK’ action is influenced by the condition of home game or visitor. O guarda-redes (GR) tem uma ação preponderante no processo ofensivo e defensivo de uma equipa de futebol. O objetivo do estudo centrou-se na análise das ações ofensivas e defensivas do GR sub-17 de futebol, recorrendo à metodologia observacional. Foram analisados GR Sub-17 (n=4) em 30 jogos do campeonato distrital da AF Lisboa. A amostra observacional foi de 286 ações defensivas e 790 ações ofensivas. Utilizámos os sistemas de observação das ações técnico-táticas ofensivas e defensivas dos GR. As ações observadas foram codificadas recorrendo ao software informático LINCE versão 1.3. O tratamento de dados foi realizado através da análise descritiva, do teste U-Mann Whitney para comparar as ações na condição de casa e fora e estatística gráfica. Verificámos nas ações defensivas maior número de ocorrências na forma de intervenção saída da baliza (n=140; 4.66±2.57), ação como último defesa (n=102; 3.4±2.34), forma de execução técnica com as duas mãos (n= 205; 6.83±3.32) e zona final da ação técnica 1 (n=155; 5.16±3.19). Nas ações ofensivas registámos mais ocorrências para forma de chegada da bola ao GR através de atraso (n=263; 8.76±3.89), início da ação na zona 1 (n=205; 13.30±4.72), ação técnica pontapé de baliza curto (n=191; 6.36±3.99), decisão tática ataque posicional (n=498; 16.60±5.87), final da ação manutenção da posse de bola (n=593; 19.76±5.81) e zona final da ação 5 (n=131; 4.36±3.47). No processo defensivo, a ação dos GR tem enorme preponderância como último defesa e defesa da baliza. No processo ofensivo as ações técnicas com os pés são relevantes na participação na construção do ataque posicional. A ação dos GR é influenciada pela condição de visitado ou visitante.
