Swimming Starting Blocks are visible in most Olympic pools and competitive pools where each individual starts their swim or relay with a dive from these blocks. Backstrokes races, however, don’t need an individual to use the starting blocks. The swimming starting blocks have grips, handles, and slots, with the handle being parallel to the end wall surface. The swimming starting blocks are available in different styles and varieties. The high variety type is fitted on the floor with projecting steps for an athlete to climb to the starting block and the low variety type fixed on the head wall.
