- Starting_blocks abstract "Starting blocks are a device used in the sport of track and field by sprint athletes to hold their feet at the start of a race so they don't slip as they push out at the sound of the gun. For most levels of competition, including all high level International competition, starting blocks are now mandatory equipment for the start of sprint races.The invention of starting blocks is credited to Australian Charlie Booth and his father in 1929.Prior to their invention, runners would dig holes in the dirt track. Trowels were provided at the start of races. This was not the most consistent or stable system. It also was destructive to the track surface with the holes having to be filled for subsequent runners. Wood was the first material used, with some tracks having permanently placed wooden starting blocks with golden structures at the start line. Portable blocks were held by long metal spikes that needed to be pounded into the ground. These devices evolved to metal blocks. The common blocks of the 1960s were heavy and adjusted by screws that were frequently broken or became rusted over the years. Lighter weight blocks were made of sheet metal.The rubberized surfaces of new All-weather running tracks that became common starting in the 1970s, made the old blocks even less secure. Original Tartan tracks left long holes to secure the blocks but most tracks required blocks to be held by small spikes similar to the ones used in shoes. Block slippage was common enough, it is an allowable loophole in the rules to recall the start of a race, without calling a "false start" against an athlete. In some amateur settings, such as high school track, since block slippage is much more common due to lower quality track surface material and/or starting blocks' spike quality, it is a commonly accepted practice to allow another person (usually a teammate) to sit on the ground behind the starting block and place their feet behind each block, using their leg power to further reduce the chance for the blocks to slip back upon the runner launching out of them.Modern blocks used for world records now must have sensors that detect the pressure from the athlete and can be used to time their reaction to the starting gun. Athletes who react faster than 100/1000ths of a second (one tenth of a second) can be charged with a false start and the race recalled. Many also carry electronic speakers so the sound of the gun arrives at the ears of the athletes at exactly the same time.".
