In swimming, "DQ" stands for "disqualification." This term refers to the removal of a swimmer from competition due to violations of the rules, such as false starts, improper stroke techniques, or illegal turns. A disqualification can have significant consequences for an athlete and their team, as it may result in lost points or rankings. To avoid DQ, swimmers must adhere to strict guidelines throughout their events, highlighting the importance of precision and adherence to the sport’s regulations.
