This study tried to secure the quantitative data through the kinematical analysis for the arm movement during swimming, and to find out the efficient type for each movement of the superior and inferior swimmers.
The conclusion of this study is as follows.
A. Displacement of Fingertips
The superior swimmer has the traces of under-water actions without unnecessary movements and gets into the gliding action as soon as he enters the water, resulting in the minimization of the gliding actions, while the inferior swimmer has too long gliding action or performs too many unnecessary movement in the water.
B. Displacement of Wrists and Elbows
The angles between fore arm and upper arm of the superior and inferior swimmers had large difference even from the gliding action, where the inferior swimmer held and drew the water with smaller angle, while, on the contrary, the superior swimmer drew the water with large angle.
C. velocity of the Fingertips
For the position change of wrist and elbow of the superior and inferior swimmers, the elbow of the superior swimmer had no case that the elbow was drawn back first, while the inferior swimmer drew back the elbow at the same time when he entered the water.
D. Velocity in Angles of the Elbow Joints
The hand tip's velocity of the inferior swimmer was faster than that of the superior swimmer. Since the elbow of the inferior swimmer was drawn back first, he had faster velocity of hand tip than the superior swimmer who raised the elbow did.
E. Velocity Angular Velocity of the Elbow Joints
The variation in angular velocity of the elbow joints of the good swimmers quickly shifted the angular velocity of the forearms and upper arms in the curving part connecting from the gliding actions to the catch actions and in the start of the pulling part.
