In this study, subjects were 90 ball-game players (basketball, rugby, and soccer). The 505 test was conducted to evaluate their agility. The aim of this study was to clarify what the test specifically evaluated, and investigate methods to utilize this test effectively. The time measured to run a course divided into 10 sections, the results of image analysis of running motions, and evaluation of the players by their coach were used as the study methods. Reproducibility was verified in the time to complete the 505 test. A significant correlation was noted in the time for the 505 test and each time for the deceleration, turning, and deceleration sections (P<0.01). In the 505 test, subjects gradually lowered their center of gravity and reduced their running speed in the deceleration section before turning, and, in the acceleration section after turning, they showed a tendency to accelerate by gradually raising their center of gravity. In the basketball and rugby groups, a significant correlation was noted between the time of the 505 test and evaluation by their coach (P<0.01); however, in the soccer group, no correlation was noted. From the above, the 505 test used in this study is considered to be appropriate to evaluate the turning ability and adjustability of the running speed before and after turning in basketball and rugby players.
