Abstract

The purposes of this study was, 1)to clarify the factorial structure of agility; and 2)to establish an agility test battery. Twelve test variables, which were selected from the viewpoint of three composite elements of agility, 1)speed of repetitive movement, 2)quickness of reaction, 3)quicknees in completing a given motion, were administered to 47 basketball players. Oblique multiple group factor solution was applied to the correlation matrix which were calculated with twelve test variables in order to clarify the factorial structure of agility. Therefore, the following four factors were extracted: 1)quickness of repeated motion; 2)quickness / of simple reaction; 3)quickness of multi-choice reaction; and 4)quickness of motion. In order to establish the agility test battery, four test variables, consisted of criss-cross jump (x_1), RT in the jumping reaction time test (x_2), RT in the multi-choice reaction time test (x_3), and MT in the multi-choice reaction time test (x_4), were selected from each factor taking account of the factorial validity and also of the practicability of tests. The formula (BPAS) for estimating the agility score of basketball players was deviced as follows: BPAS=0.013x_1-4.303x_2-3.759x_3-1.744x_4+3.454 The validity of BPAS was tested to be high from the two standpoints: 1)whether skilled basketball players could be discriminated from novice basketball players by BPAS; and 2)whether the significant differences between BPAS average of skilled basketball players and that of novice ones could be found.
