The Illinois Agility Test is used to evaluate which physical quality?

• A. Flexibility
• B. Agility
• C. Endurance
• D. Balance

Answer: (B)

Agility is the ability to move quickly and change direction with control. The Illinois Agility Test is built to measure exactly that: how fast a person can complete a course that forces rapid accelerations, decelerations, and changes of direction around a set of cones. The overall time reflects how efficiently the neuromuscular system coordinates sprinting speed with abrupt direction shifts, plus balance and leg strength needed to execute those moves smoothly. While flexibility, endurance, and static balance play a role in performance, they aren’t the primary determinant of the score here—the test focuses on change-of-direction speed and control, which is the essence of agility.
