A "starting block" is a device used in track and field events, particularly in sprinting. It consists of a frame with adjustable footrests that athletes use to push off at the beginning of a race. The starting block helps runners achieve better acceleration by providing a stable base for their feet. Typically made of metal or plastic, starting blocks are placed on the track before a race begins. Athletes secure their feet in the blocks and, upon hearing the starting signal, they push off with force to gain speed. This equipment is essential for competitive events like the 100 meters and 200 meters sprints.
