Research Abstract	(1) The present study sought to perform a three-dimensional analysis of the "Tenchi-nage", a typical aikido technique. The elbow joint among the advanced trainee was rotating in the first half of the throw, and the elbow progressed greatly in the latter half of the throw. (2) The intensity of Aiki-do practice evaluated by Carvonen-way was 50% maximal oxygen intake practicing relative practice within peer with equal skill level and 60%VO2 practicing 20 times individual behind-fallings (Ushiro-ukemi). (3) The longitudinal changes of the measurements of physical fitness and motor ability tests among high school students who have been practicing aikido for 0.5 or 2.5 years were analyzed. Among the aikido male students, every measurement was developing in 2.5 years of school life or aikido life.
