摘要：Match analysis is of great importance for the study of performance at an individual or collective level. In this context,the notational analysis represents an element of self-evaluation to verify what is done in the field by the players in a team sport like football. Several studies have dealt with evaluating: goal scoring,influence 1st victory goal,losing teams winning losses,types of offensive actions. This study aims to assess the ways in which a U16 team has scored goals and how these have evolved over the course of a championship (2017/2018).The matches were resumed and subsequently analysed. The elements taken into consideration were: timing of the goal,type of possession,number of passes,duration of the action,and area of commencement of the action. By category of possession,3 main categories have been identified: Fast Action (AV,maximum 3 passes),Open Action (AM,at least 4 passes),Set-piece Football (CP). For the area where the possession of the ball began,the areas were divided as follows: Zone 1 defensive,Zone 2 pre-defensive,Zone 3 pre-offensive,Zone 4 offensive.The results showed 19 goals from AV,13 from AM and 4 from CP;2 goals from Zone 1,12 from Zone 2,13 from Zone 3,5 from Zone 4. The following differences were detected between the outward and return journeys: average passes decreased from 4.69 to 3.21,average duration of the action decreased from 13.14 to 11.37;7 more goals from AV the round of return;from Zone 3,3 goals more in the Round of Return and 6 goals from AV against 1 goal from AM;+4 goals scored,-5 goals conceded,+1 point. All these elements combine to highlight the characteristics of the team and the players,the effectiveness of the training course and the evolution of the variables examined.
