TExES Physical Education EC-12 Practice Exam 2026 – Comprehensive Test Prep

Flexibility is the correct choice for assessing potential musculoskeletal problems because a lack of flexibility can indicate issues with muscle and joint function. Flexibility assessments typically involve measuring the range of motion in various joints, which can highlight areas that may be too tight or imbalanced. This tightness can lead to injuries or musculoskeletal discomfort.

While aerobic performance, muscular strength, and muscular endurance are important aspects of physical fitness, they do not directly assess the functional range of motion and the potential for musculoskeletal problems in the same way flexibility assessments do. Aerobic performance focuses on cardiovascular health, muscular strength examines force generation capabilities, and muscular endurance assesses how well muscles can sustain repeated contractions. None of these evaluate the flexibility of the muscles and joints, which is crucial for healthy movement patterns and injury prevention.
