Détermination Des Indicateurs Technico-tactiques De Performance Dans Le Football Algérien : Etude Portant Sur La Ligue De Football Professionnel 1 Et L’équipe Nationale

Résumé: The aim of the present study was to identify performance indicators that may discriminate between winning, drawing and losing in Algerian football. The sample comprised of sixty-four games in the Professional Football League 1 (LFP1) played during the 2015/16 season and eleven games of the national team (NT) in the same season. The study focuses on fourteen technical elements, nine of them are related to attacking play: possession, pass, shot, cross, corner, free kick, touch, 6 meters and goal; and 5 are related to the defence: foul committed, ball recovery, duel won, second ball and yellow card. The analysis was carried out by the DARTFISH 5.5 Pro software. The comparison revealed that when winning, the national team records a higher number of passes (P< ;0.05) with a significant participation of the central defender (P<0.01), a lower number of crosses (P<;0.05) and fouls committed (P<0.05), a higher percentage of successful shots (P<0.05) and a lower shot/goal ratio. On the other hand, success in LFP1 is characterised by, a higher number of fouls committed (P<0.05) and duels won (P<0.05), a lower number of unsuccessful shots (P<0.05), free kicks obtained (P<0.05) and throw in (P<0.05) especially in the middle area (L4) (P<0.01) and a lower shot/goal ratio. The study of the interaction between elements revealed that success in LFP1 is characterised by a strong positive correlation between: unsuccessful passes and ball recoveries (R=0.76; P<0.001); total shots and successful shots (R=0.67; P<0.001). Otherwise, failure in LFP1 is characterised by a positive correlation between the number of crosses and four elements: possession (R-0.67; free kicks (R=0.64; P<0.01), corners (R=0.65; P<0.01) and total shots (R=0.54; P<0.01). Logistical regression has led to a model for predicting success. Probability of winning in LFP1 (%) =1 / (1 + Exp [(-12,299) + (0.686 * crosses) - (0,222 * free kicks) - (0,648 * shots + (0,022 * total passes) - (38,288 * Possession) + (0,115 * Duels) + (1.594 * successful shots)] Probability of winning for NT (%) =1 / (1 + Exp (37.434 - ((-84.32 * Possession) + (93.92 * % Successful passes) + (0.53 * shots))) In conclusion, the failure in LFP1 is linked to the inability to create situations that lead to effective shooting; frequent interruption times preventing continuous game construction. While failure for the NT is linked to the inability to develop a game based on collective possession originatedfrom the line of defence.
