| Summary: | 碩士 === 國立體育大學 === 運動保健學系 === 106 === Background: Agility is a very important component in team sports. However, cognitive factor was easily overlooked in previous researches. Reactive agility tests (RAT) was developed and used to measure cognitive abilities with great test-retest reliability. Although RAT has been widely used as an agility test incorporating cognitive factors, the feasibility as a field test is still unclear. Purpose: The purpose of this study was to identify whether the acceleration of center of mass combined with decision time can represent the cognitive ability in RAT. Methods: Ten female subjects with 1-2 years of basketball training experience were recruited. Height and weight, decision time (DT), second decision time (SDT), movement time (MT), three-axes average acceleration of DT, SDT, MT, and defensive results were then assessed for each subject. According to the defensive results, data were divided into high and low performance group. Independent t-test was used to analyze the difference in performance, defensive results, DT and acceleration of three-axes. The Pearson correlation coefficient test was used to compare the correlation between DT, SDT, MT, and acceleration of three-axes. The significant level of this study was set at α = .05. Result: The RAT data were divided into two situations: non-feint and feint. In the non-feint, there is significant difference in DT between different performances. In the defensive results, there was only significant difference in DT and mediolateral axis mean acceleration. In the feint group, there is significant difference in average acceleration of three-axes in MT between different performances and in the defensive results there was only significant difference in DT. In the non-feint, DT was significantly correlated with average acceleration of three-axes. In the feint, there was a significant correlation between the SDT and the MT and SDT accelerations of three-axes, and there was a significant correlation between the MT and MT vertical acceleration. Conclusion: In the non-feint, mediolateral axis mean accelerations in DT and DT can be used for assessing RAT cognitive performance. In the feint group, DT, SDT, MT and three-axes average acceleration in DT, SDT, MT cannot be used for assessing RAT cognitive performance.
