A technical fault in handball refers to a mistake or error committed by a player or team that results in the loss of possession. It is a violation of the game rules or an infraction such as a double dribble, traveling, or stepping into the crease as a goalkeeper. Tagging technical faults during video analysis helps identify areas of weakness or lapses in player execution. By reviewing these instances, coaches and players can address individual or team-specific technical deficiencies, refine playing techniques, and minimize errors during future games.
