Which agility test involves rapid changes of direction?

The T-Test is specifically designed to measure agility, which is the ability to change direction quickly while maintaining control. In this test, the participant runs forward, then makes a series of lateral and backward movements to complete a zigzag pattern around cones. This sequence of movements requires not only speed but also the ability to rapidly change direction, which is a key component of agility.

In contrast, the Vertical Jump Test focuses on explosive leg power and does not assess directional movement. The 40-Yard Dash primarily measures straight-line speed without assessing agility or the ability to change directions. The Stair Climb Test is more about endurance and strength rather than the quick directional changes that characterize agility. Therefore, the T-Test is the most appropriate choice when it comes to assessing rapid changes of direction.
