Question: 1 / 415

What does muscular flexibility refer to?

The maximum amount of force exerted by muscles

The range of motion at a joint without injury

Muscular flexibility specifically refers to the range of motion at a joint or group of joints, which is achieved without causing injury. This concept is crucial in physical fitness, as it influences overall mobility, functional movement, and the ability to perform exercises effectively and safely. Flexibility can enhance athletic performance, reduce the risk of injuries, and improve posture and balance.

Considering the other options, muscular strength relates to the maximum force exerted by muscles, endurance refers to the ability to sustain prolonged physical activity, and the size of muscle fibers pertains to muscle mass rather than flexibility. Therefore, option B accurately captures the essence of what muscular flexibility entails.
