The Periodic Table of Elements is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter test will begin in 30 seconds; line up at the start. The running speed starts slowly, but gets faster each minute after you hear this signal. ⭐ A single lap should be completed after you hear this sound. ✨ Remember to run in a straight line, and run as long as possible. The second time you fail to complete a lap before the sound, the test is over. The test will begin on the word start. On your mark, get ready, start.
