Whether attacking or defending, agility skill requires the ability to perceive relevantinformation about opponent’s movements and react quickly and accurately. Some agilitytests have been able to isolate the decision-making time from the total agility action. This istypically done by using high-speed video to determine the time from the stimulus (attacker’sinitial change of direction movement) to the tested athlete’s first response [6, 11, 15, 17, 18,19, 23]. In one study [17], the decision time only represented 3.6% of the total agility time,but the correlation between decision time and total agility time was r=0.77. The correlationcoefficient between the responding movement time and total agility time was r=0.59,indicating that the decision-making time was even more influential to agility performancethan the movement that followed. More recently, Scanlon et al. [6] reported that decisiontime was significantly correlated (r=0.577, p<0.05) with an agility test in basketball players,International Journal of Sports Science & Coaching Volume 10 · Number 1 · 2015 161and concluded that cognitive qualities are important to develop agility in basketball.
