Ice-skating jumps are a type of figure skating element that involve the skater launching into the air and rotating multiple times before landing on the ice. The three most common jumps are the Salchow, Axel, and Lutz. The Salchow is named after its inventor, Ulrich Salchow, and involves the skater taking off from the back inside edge of one foot and landing on the back outside edge of the other foot. The Axel is named after its inventor, Axel Paulson, and involves the skater taking off from the forward outside edge of one foot and landing on the same backward outside edge of the other foot. The Lutz is named after its inventor, Alois Lutz, and involves the skater taking off from the back outside edge of one foot and landing on the back outside edge of the other foot.
