Synchronized swimming trains swimmers on advanced water skills, and requires great strength, flexibility, precise timing as well as exceptional breath control especially when upside down of water. A great sport for kids to start at young age!
A little history on synchronized swimming:
In 1907, Australian Annette Kellerman was noted as the first underwater ballerina at the New York Hippodrome when she performed in a glass water tank and attracted national attention. After experimenting with various different diving actions and stunts in the water, Katherine Curtis starts one of the first water ballet clubs at the University of Chicago, where the team began executing strokes, 'tricks,' and floating formations. On May 27, 1939, the first U.S. synchronized swimming competition took place at Wright Junior College between Wright and the Chicago Teacher's College.
