A single Axel jump.
|Element name:||Axel jump|
|Alternative name:||Axel Paulsen jump|
|Take-off edge:||Forward outside|
|Landing edge:||Back outside|
The axel jump, also called the Axel Paulsen jump for its creator, Norwegian figure skater Axel Paulsen, is an edge jump in the sport of figure skating. It is figure skating's oldest and most difficult jump. It is the only jump that begins with a forward takeoff, which makes it the easiest jump to identify. A double or triple axel is required in both the short programs and free skating programs for junior and senior single skaters in all International Skating Union (ISU) competitions. According to The New York Times, the triple axel "has become more common for male skaters" to perform, although the quadruple axel has not yet been successfully completed in competition. As of 2019, 10 women have successfully completed the triple axel in competition. The axel has half an extra rotation, which, as figure skating expert Hannah Robbins states, makes a triple axel "more a quadruple jump than a triple".
The axel jump, also called the Axel Paulsen jump for its creator, Norwegian figure skater Axel Paulsen, is an edge jump in the sport of figure skating. Figure skating historian James Hines calls the axel "figure skating's most difficult jump". It is the only jump that begins with a forward takeoff, which makes it the easiest jump to identify. Skaters will often perform a triple or quadruple axel, followed by a simpler jump, during combination jumps.
In competitions, the base value of a single axel is 1.10; the base value of a double axel is 3.30; the base value of a triple axel is 8.00; and the base value of a quadruple axel is 12.50. A double or triple axel is required in both the short programs and free skating programs for junior and senior single skaters in all International Skating Union (ISU) competitions. The axel jump is the most studied jump in figure skating.
The first skater to accomplish an axel was its creator, Axel Paulsen, in 1882 at the first international figure skating competition, which was held in Vienna. By the mid-1920s, the axel was the only jump that was not being doubled. Professional German skater Charlotte Oelschlägel, during the early 1900s, was the first woman to include an axel in her programs; Hines reported that she would terminate the axel with her "famous fade-away ending", the Charlotte spiral, a move she invented. In the early 1920s, Sonja Henie from Norway was the first woman skater to perform an axel in competition. Hines also reports that in the 1930s, Austrian skater Felix Kaspar, who was known for his athleticism, performed axels that were four feet high and 20 feet from takeoff to landing; Hines stated that "there is little doubt in the minds of those who saw him that had the technique then been known, he probably could have easily performed triple or even quadruple jumps".
American Dick Button was the first skater to compete a double axel in competition, at the 1948 Winter Olympic Games. American Carol Heiss was the first woman to perform a double axel, in 1953. The first triple axel in competition was performed by Canadian Vern Taylor at the 1978 World Championships. The first male skater to complete a triple axel during the Olympics was Canadian skater Brian Orser in 1984. The first throw triple axel was performed by American pair skaters Rena Inoue and John Baldwin, at the 2006 U.S. National Championships. As of 2018, the quadruple axel has not been successfully completed in competition.
According to The New York Times, the triple axel "has become more common for male skaters" to perform. The first woman skater to complete a triple axel was Japanese skater Midori Ito, at the 1989 World Championships. Only three women have completed the triple axel during the Olympics: Ito in 1992, Japanese skater Mao Asada in 2010 and 2014, and American skater Mirai Nagasu in 2018. Tonya Harding was the first American woman skater to complete the triple axel in competition, at the 1991 U.S. Championships; it was another 10 years before another woman skater attempted it. As of 2019, 10 women have successfully completed the triple axel in competition, three in the 2018-2019 season: Russian skater Elizaveta Tuktamysheva, Japanese skater Rika Kihira, and American skater Alysa Liu.
The axel is an edge jump, which means that the skater must spring into the air from bent knees. It is the oldest but most difficult figure skating jump. The axel has three phases: the entrance phase (which ends with the takeoff, the flight phase, when the skater rotates into the air, and the landing phase, which begins when the skater's blade hits the ice and ends when he or she "is safely skating backwards on the full outside edge with one leg behind in the air". According to researcher Anna Mazurkiewicz and her colleagues, the most important parts of the entrance phase is the transition phase (also called the pre-takeoff phase) and the takeoff itself. It has a forward takeoff, approached with a series of backward crossovers in either the opposite or the same direction to the jump's rotation, followed by a step forward onto the forward outside takeoff edge.
The skater must also approach the jump from the left forward inside edge of his or her skate, enabling the skater to step forward. The skater then kicks through with his or her free leg, helping him or her to jump into the air. The skater must land on the right back inside edge of his or her skate. The change in foot required to complete the axel means that the skater must transfer his or her center of gravity, from the left side of his or her body to the right side, while rotating in the air so that he or she is in the correct position to land. As a result, the axel has half an extra rotation, which, as figure skating expert Hannah Robbins states, "makes a triple axel more a quadruple jump than a triple": the single axel consists of one-and-a-half revolutions, the double axel consists of two-and-half rotations, and the triple axel consists of three-and-a-half rotations.
Sports reporter Nora Princiotti states, about the triple axel, "It takes incredible strength and body control for a skater to get enough height and to get into the jump fast enough to complete all the rotations before landing with a strong enough base to absorb the force generated". According to American skater Mirai Nagusu, "falling on the triple axel is really brutal". It has been shown that the more skilled skaters have greater takeoff velocities and jump lengths. When skaters perform double axels, they exhibit greater rotations during the flight phase, take off in more closed positions, and attain greater rotational velocities than when performing single axels. They also increase their turns not by increasing the time in the air, but by increasing their rotational velocity when performing single, double, and triple axels. According to researcher D.L. King, the key to executing a successful triple axel is "achieving a high rotational velocity by generating angular momentum at take-off and minimising the moment of inertia about the spin axis".
