According to NASM progressions, which sequence correctly describes advancing balance training difficulty?
Answer: Stable to unstable, slow to fast, eyes open to eyes closed
Balance training progresses from stable to unstable surfaces, slow to fast speeds, and eyes open to eyes closed to systematically increase sensorimotor demand.
Reciprocal inhibition refers to:
Answer: Relaxation of the antagonist when the agonist contracts
Reciprocal inhibition is the automatic neural inhibition of the antagonist muscle when the agonist fires, allowing smooth, unimpeded joint movement.
Which of the following exercise choices best reflects the Activate phase goal of neuromuscular re-education?
Answer: Single-leg calf raises on a balance pad
Performing calf raises on an unstable surface targets isolated activation of the targeted muscle while simultaneously challenging proprioceptive and neuromuscular control.
Synergistic dominance is best described as:
Answer: A synergist muscle compensating for an underactive prime mover
Synergistic dominance occurs when a synergist takes on the role of an inhibited prime mover, producing altered movement mechanics and increasing injury risk.
Lower crossed syndrome involves which pattern of muscle imbalance?
Answer: Overactive hip flexors/erector spinae and underactive glutes/deep abdominals
Lower crossed syndrome is characterized by tight/overactive hip flexors and erector spinae crossing with weak/underactive gluteus maximus and deep abdominal stabilizers.
During single-leg balance exercises, which muscle group is most critical for preventing medial knee collapse (valgus)?
Answer: Hip abductors and external rotators
The hip abductors (especially gluteus medius) and external rotators control femoral position, preventing adduction and internal rotation that causes the knee to cave medially.
The stretch-shortening cycle (SSC) is best described as:
Answer: Eccentric loading immediately followed by a concentric contraction
The SSC involves an eccentric pre-load that stores elastic energy in muscle-tendon units, immediately followed by concentric contraction that releases that stored energy for greater power output.
