True or False: Knee flexion focuses on the muscles responsible for bending the knee, while knee extension focuses on the muscles responsible for straightening the knee.

The statement is true because knee flexion does indeed involve the muscles that are responsible for bending the knee, primarily the hamstrings, while knee extension involves the muscles that are responsible for straightening the knee, primarily the quadriceps.

Understanding these movements is crucial for designing effective training programs, particularly for seniors, as maintaining strength and flexibility in these muscle groups can enhance mobility, balance, and overall functional performance. The distinction between flexion and extension is fundamental in rehabilitation and fitness training, especially for older adults who may be recovering from injuries or managing age-related changes in muscle strength. Thus, recognizing the roles of flexion and extension in knee movement is essential for safe and effective exercise programming.
