Hamstrings are parallel to the floor or lower. D. Knees caving inward (knee valgus). 13. A key benefit of performing the **air squat** before progressing to weighted variations is: A. Maximizing muscle hypertrophy. B. Building a strong foundation by focusing on form, mobility, and stability. C. Placing maximum force on the gluteus maximus. D. Avoiding the need for any core engagement. 14. What is **Knee Valgus**? A. The knees bowing outward during the squat descent. B. The knees caving inward toward each other during the squat descent. C. Maintaining proper knee alignment over the toes. D. Excessive knee extension at the top of the squat. 15. Which of the following is a potential cause of **Knee Valgus** during squatting? A. Weak gluteus medius muscle. B. Strong quadriceps muscles. C. Excellent ankle dorsiflexion. D. Toes pointed excessively outward. 16. When squatting, what is the importance of maintaining an even weight distribution on the **foot tripod**? A. To increase the load on the toes for a faster ascent. B. To ensure a sturdy base, prevent foot rolling, and improve stability for a heavier squat. C. To maximize hip flexion and trunk lean. D. To intentionally shift weight to the heels for all squat variations. 17. In the context of squatting with long limbs, why is the **low bar position** often preferred? A. It increases the demand for knee flexion. B. It allows for a more upright torso and reduces forward lean, improving balance. C. It targets the quadriceps exclusively. D. It is required for Olympic weightlifting. 18. What is the main effect of restricted ankle mobility during a squat? A. Causes excessive hip extension. B. Requires a greater degree of knee valgus. C. May cause the heels to rise, leading to compensatory techniques and increased injury risk. D. Maximizes gastrocnemius muscle activation. 19. Which adjustment to the stance can help compensate for limb length disparities (e.g., long femurs)? A. Narrower stance with toes pointing straight ahead. B. Wider stance and moving the toes outward. C. Eliminating the hip hinge movement. D. Increasing the squat depth beyond comfort. 20. What is the consequence of a *smaller* femoral neck angle on squat mechanics? A. Allows for a more upright torso and greater hip range of motion. B. Can result in a forward-leaning torso and a challenge to achieve full depth. C. Forces the knees to move outward (valgus). D. Shifts the load primarily onto the glutes and hamstrings. 21. The tibiofemoral joint in the knee flexes within what approximate sagittal range during dynamic movement? A. 0 to 45 degrees B. 90 to 120 degrees C. 0 to 160 degrees D. 120 to 180 degrees 22. What is a key purpose of incorporating **elevated heels** during a squat? A. To increase the load on the lower back. B. To intentionally increase knee valgus. C. To improve ankle dorsiflexion and permit a more upright torso position. D. To shift the primary muscle focus entirely to the hamstrings. 23. How should the knees track relative to the toes during the squat descent? A. The knees should collapse inward, in front of the toes. B. The knees should track over the toes, without collapsing inward. C. The knees should remain stationary behind the toes. D. The knees should track far outside the toes. 24. The overhead squat is often used as a diagnostic tool to identify what throughout the entire body? A. Absolute maximum strength. B. Areas of weakness or limitation in mobility, stability, and strength. C. The ratio of Type I to Type II muscle fibers. D. The effect of varying bar paths on joint torques. 25. The gluteus maximus, medius, and minimus are primarily accountable for which two hip movements? A. Hip Flexion and Internal Rotation B. Hip Adduction and Hip Abduction C. Hip Extension and External Rotation D. Spinal Extension and Pelvic Tilt 26. What common squatting error can result from poor core stability or limited hip/ankle/thoracic spine mobility? A. Hip Abduction B. Hip Flexion C. A rounded back during squats D. Knee Plantarflexion 27. What is the typical recommendation for toe-out angle and stance width when setting up for a squat? A. Feet narrow, toes pointed straight forward. B. Feet shoulder-width or slightly wider, toes pointed slightly outward (15-30 degrees). C. Feet wide, toes pointed straight forward. D. Feet together, toes pointed sharply inward. 28. The Sumo Squat variation primarily focuses on which lower body muscles? A. Calves and Hamstrings. B. Quadriceps, Glutes, and Inner Thighs. C.
