What name is given to the agility test that involves changing directions and accelerating multiple times?

The agility test that specifically involves changing directions and accelerating multiple times is commonly known as the Pro Agility Test. This test measures an athlete's ability to accelerate, decelerate, and change directions quickly, which is critical in many sports. The Standard Pro Agility Test involves a series of sprints and lateral movements over a defined distance, typically focusing on quick transitions between forward and lateral movement.

The 3-5-7 test, while it may sound similar and also involves agility, does not capture the full essence of changing directions and acceleration in the same way that the Pro Agility Test does. Instead, this test typically focuses on running a specific pattern, but it isn't as widely recognized as the Pro Agility Test for assessing agility in athletes.

In summary, the Pro Agility Test is the most appropriate descriptor for an agility test that involves multiple direction changes and accelerations, showcasing an athlete's overall agility and quickness in movement.
