What is a critical quality described by agility?

Agility is characterized by the ability to change body direction quickly and effectively. This quality is essential in various physical activities and sports, as it allows individuals to respond rapidly to changing conditions and dynamics, whether in games like soccer or basketball or in activities that require quick movement and reflexes. Agility combines speed, coordination, and balance to enable performers to navigate their environment efficiently and effectively.

The other options describe different physical attributes: endurance relates to aerobic ability, balance involves stability during steady movements, and strength pertains to lifting capabilities. While all these qualities are important in fitness and athletic performance, they do not encompass the essence of agility, which is specifically about rapid directional change.
