Which of the following is a benefit of agility training for tactical athletes?

Agility training is particularly beneficial for tactical athletes because it enhances coordination and quickness. These attributes are crucial in scenarios that require rapid movements and the ability to change directions efficiently, which are common in various tactical operations. Improved coordination allows athletes to effectively manage their body movements in response to dynamic environments or unexpected situations, while quickness aids in rapid responses to threats. These qualities contribute to overall performance and safety in tactical settings, making agility training an essential component of their conditioning programs.

The other options do not align with the primary benefits associated with agility training. For example, increasing muscle mass is typically achieved through resistance training rather than agility drills, while aerobic capacity is improved through endurance-specific training rather than agility work. Lastly, reduction of flexibility is not a goal or benefit of agility training; rather, flexibility is generally maintained or improved through a balanced training program that incorporates stretching.
