Stimulus tempos and the reliability of the successive choice reaction test.

In ball game sports, players demand agility, which is a quick and adequate reaction to various changing stimuli. We developed a "successive choice reaction test" that evaluates such agility. This test requires subjects to be exposed to successive stimuli. Hence, it is very important to select appropriate stimulus tempos. In addition, it is necessary to examine the reliability of a new test. This study examined adequate stimulus tempos and test reliability. Fifteen healthy university students participated in this study. All the subjects conducted a successive choice reaction test with 3 kinds of tempos (1.3, 1.5, and 2.0 seconds). To examine its reliability, the test was conducted again on another day. It was found that any tempo has a high reliability, that their relationships are close, and insignificant time differences exist among the tempos. In conclusion, the successive choice reaction test was judged to be useful with any of the above tempos.
