Abstract

The purpose of this research was to evaluate a reactive agility test by determining the relationships between the total time recorded for the test and various components. A tester used side-step movements to provide a stimulus for the athlete to change direction. By using electronic timing and high speed video analysis of the test, three times were recorded. These were the time taken for the tester to display the stimulus to change direction (tester time), the time taken by the participant to respond to the stimulus (decision time), and the time taken by the participant to change direction and sprint to the left or right (response movement time). Thirty-one semi-professional Australian Rules football players were assessed by analysing the mean of eight trials of the reactive agility test. The greatest correlation with total time was r=0.77 for decision time (p=0.00), with movement time and tester time producing coefficients of 0.59 (p=0.00) and 0.37 (p=0.04), respectively. The coefficient of variation for the mean tester time was 5.1%. It was concluded that perceptual skill as measured by decision time is an important component of the reactive agility test and the tester time should be controlled by using high speed video recordings to isolate its influence.
