Here is the rephrased text:
A renowned fitness assessment tool, the FitnessGram(TM) Pacer Test is a multi-stage aerobic capacity evaluation that becomes increasingly demanding as it progresses. The 20-meter pacer test is set to commence in exactly 30 seconds. Please form a line at the designated starting point.
The test begins with a slow jogging pace, which gradually accelerates every minute after the initial signal. This signal is a distinct beep, which serves as a cue for participants to complete a single lap around the course. It is essential to maintain a straight line and continue running for as long as possible.
The test will come to an abrupt halt the moment you fail to complete a lap before the second signal, which is a distinct ding. This signal marks the end of the test. To ensure a smooth and accurate assessment, please note that the test will commence promptly on the word "start." With that, you are now ready to begin. On your mark, get ready, start!
