First, read the English article below.

Running the 100m requires you starting in a certain stance so that you can propel yourself with maximum force and momentum forward. In order to do this, many coaches and professionals recommend and use foot blocks that are designed for your feet and legs to start in the best position to build momentum. When you get your foot blocks, practice your starting stance:  Your front foot will be about two feet from the starting line. Your back foot will be at a toe-to-heel footing in relation to your front foot. Your body will be leaning forward toward the starting line. Your arms will be spread shoulder-width apart from each other. Your hands will be touching the starting line with your index finger and thumb extended onto the line. Fundamentally, your starting stance and starting technique can cause you to win or lose the sprint. Not only is sprinting more intense, it demands the use of more muscle groups than running, and requires technique so that you can harness your energy and power forward on the field. You need to practice your technique, relying on your starting stance, so that you can build the most momentum going into the race. To start the 100m:  Your back leg, which starts off extended, will take the first quick step and come forward. Your front leg will then quickly move forward and propel you forward. Your hips will extend and catapult you upward and ahead.
