Which of the following actions is not considered flagrant misconduct?

Flagrant misconduct refers to actions that display a blatant disregard for the rules or sportsmanship in wrestling, which typically includes aggressive or unsportsmanlike behavior. Among the listed options, the choice regarding failure to keep shoulder straps up is not considered flagrant misconduct because it pertains to a minor equipment issue rather than an intentional action that disrupts the match or poses a safety threat to others.

In contrast, physical aggression towards an opponent can be classified as flagrant misconduct because it shows a willingness to harm or excessively intimidate an opponent. Using illegal holds also falls under this category as it violates the rules of the sport, potentially leading to injury and undermining fair competition. Similarly, persistent stalling calls reflect an unwillingness to engage in the match appropriately, which can be seen as a strategy that undermines the spirit of the competition. Each of these actions directly impacts the integrity of the match and the safety of participants, distinguishing them from the more passive violation of equipment regulation indicated in the correct answer.
