If, in the judgment of the starter or recallers, he does so any earlier, it is considered a false start. It is deemed a false start if, in the judgment of the starter an athlete fails to comply with the commands "on your marks" or "set" as appropriate after a reasonable time; or an athlete after the command "on your marks" disturbs other athletes in the race through sound or otherwise. If the runner is in the "set" position and moves, then the runner is also disqualified. , any athlete making a false start is disqualified.
