In competitive sports of an open-skill system, rapid information-processing ability and adequate movement ability corresponding to rapidly changing information and stimuli are demanded athletes. This study examined the agility characteristics of athletes by using a successive choice reaction test. The subjects included 80 male university athletes, with 10 athletes randomly selected per competitive event for a total of eight competitive events. A successive choice-reaction test comprising five step patterns was used. A cell placement similar to step sheet placement was presented to the subjects on a personal computer display. The cell (sheet) for the athletes to step into was continuously and randomly indicated. The athletes quickly stepped onto eight sheets that corresponded to each cell shown on the display in each pattern. The entire process for achieving each pattern required eight steps (between stimulation presentation and step landing). From among the five patterns, the patterns with the minimum and maximum times were excluded. A mean of the total time for three patterns was used as an evaluation variable. Results of the statistical analysis including a one-way ANOVA indicated that the reaction time was significantly shorter in open-skill sports athletes than in closed-skill sports athletes. In conclusion, athletes in open-skill sports have superior successive choice reaction ability when compared with the athletes in closed-skill sports.
