Play an AI-generated podcast conversation about this lesson

What is the definition of balance in the context of posture and movement?

The ability to maintain the line of gravity within the base of support with minimal postural sway (correct)

The ability to maintain a stable posture with minimal muscle activation

The ability to generate maximum force in a specific direction

The ability to change direction quickly and efficiently

What is the result of equilibrium in a system?

Decreased stability

Increased muscle activation

Increased postural sway

All acting forces are cancelled by each other resulting in a stable balanced system (correct)

What is the effect of a wider base of support on balance?

Decreased balance

Increased balance (correct)
