Mitsuo Tsukahara
[1] Tsukahara competed throughout the late 1960s and 1970s, retiring from gymnastics competition in 1978 after the World Championships.[2] Tsukahara's name is one of the most famous in gymnastics due to its association with two widely performed skills.The Men's Gymnastics Code of Points credits Tsukahara for premiering this skill on floor exercise and horizontal bar, and he regularly performed it on these events throughout his career.In fact, in many nations, it is customary to call a full-twisting double salto tumble or dismount a "Tsukahara" on all apparatus, both for men and women.The name "Tsukahara" is so strongly associated with the 1/4-on entry, that it is routinely misapplied to the more commonly used Kasamatsu-style vault, in which the 1/4 turn off the horse "untwists" so that the salto is initiated forwards or sideways.
