"Freestyle roller skating dates back to the early twentieth century, when roller skaters began adapting movements from ice skaters in the 1930s and 1940s. During this same time, roller skaters began creating their own movements. In the 1940s, after completing the required figure skating movements during competition, a roller skater could then execute their own fancy figures or trick skating to reveal their skill as a skater. In 1949, freestyle separated from figures, resulting in its own competition. New movements were often named for the skater who first performed them during a freestyle event. Freestyle skating involves interpreting the tempo and mood of the music during the routine and each skater is judged by his or her speed, height of jumps, sureness of spins, and connective footwork."
