History
Rolling hoops or krikoi were a popular form of recreation at ancient Greek gymnasiums. Participants used chest-high hoops and tried to keep them rolling using a 12-inch stick called an "elater". Children also used hoops for tumbling and dance similar to rhythmic gymnastics. Prominent Greek physician Hippocrates endorsed rolling hoops as a healthy form of exercise.
Hoop Construction
Hoops were made of wood, bronze, iron or copper. Hoop makers would form a narrow, flat strip into a large ring in various sizes to suit the height of the player.
How to Play
Bowling or trundling hoops has entertained children in many cultures for hours who compete to keep their hoops upright and in motion the longest. Children would set the hoop rolling and run after it, attempting to drive it by striking the flat edge with the elater stick. Successful driving technique includes striking wooden hoops with the center of the stick or guiding metal hoops with a metal hook attached to the stick. Starting on a slight incline helps beginners to get the knack of maintaining the hoop's forward motion.
Races
Players would often hold hoop rolling races. Set up a straight or winding course on a flat surface, depending on the skill level of the participants. Variations for more advanced players include jumping through the hoop as it rolls or having a partner throw small rocks or bean bags through the rolling hoop. If the hoop falls, the player is disqualified. The first person or team to cross the finish line with a rolling hoop wins.
