The technical rules of swimming are designed to provide fair and equitable conditions of competition and to promote uniformity in the sport. Each swimming stroke has specific rules designed to ensure that no swimmer gets an unfair competitive advantage.
Start of the Race
At the commencement of each heat, the referee signals to the swimmers to get ready with a short series of whistles, followed by a long whistle, which indicates they should take their positions on the starting blocks.
When everyone is ready, the referee signals with an outstretched arm to the starter that the swimmers are ready.
The starter will issue the command “take your mark” and the swimmers will immediately assume their starting position. When all swimmers are stationary, the starter will give the starting signal.
A swimmer that starts before the starting signal will be disqualified. When that occurs, swimmers remaining on the starting blocks will be able to leave their starting positions when the “Stand up” command is issued.
If the starting signal has been given before the disqualification is declared, the race will continue without stopping. If both the referee and starter observe the violation, the swimmer or swimmers involved will be disqualified once the race is finished.
In preliminaries and finals meet, a swimmer may compete in no more than three individual events per day.
In a timed finals meet, a swimmer may compete in no more than six events per day.
