Q1Which type of stretching relies on reciprocal inhibition to facilitate muscle lengthening?
✓ Correct answer: D. Active stretching
Active stretching relies on reciprocal inhibition, a neurophysiological principle where the antagonist muscle relaxes when the agonist contracts. This allows for more effective lengthening of the target muscle.
Q2In the NASM Corrective Exercise Continuum, which technique should immediately precede lengthening techniques?
✓ Correct answer: C. Inhibitory techniques
In the NASM Corrective Exercise Continuum, inhibitory techniques (like self-myofascial release) should immediately precede lengthening techniques to reduce muscular tension before attempting to increase range of motion.
Q3What is the recommended duration for a static stretch when applying lengthening techniques to overactive muscles?
✓ Correct answer: B. 30 seconds
According to NASM's corrective exercise protocols, static stretches should be held for 30 seconds to achieve optimal lengthening of overactive muscles.
Q4Which of the following is a key principle when applying static stretching in a corrective exercise program?
✓ Correct answer: A. Focus on stretching muscles identified as overactive during assessment
Static stretching should specifically target muscles identified as overactive during the assessment process to address specific muscle imbalances, rather than general stretching of all muscle groups.
Q5What neurophysiological mechanism primarily explains the effectiveness of PNF stretching techniques?
✓ Correct answer: D. Autogenic inhibition
PNF (Proprioceptive Neuromuscular Facilitation) techniques primarily work through autogenic inhibition, where the Golgi tendon organs respond to tension by causing the muscle to relax, allowing for greater range of motion.
Q6Which stretching technique involves actively contracting the muscle opposite to the one being stretched?
✓ Correct answer: C. Active stretching
Active stretching involves contracting the antagonist muscle (the one opposite to the muscle being stretched) to create reciprocal inhibition, allowing for greater lengthening of the target muscle.
Q7What is a primary contraindication for applying aggressive lengthening techniques?
✓ Correct answer: B. Acute inflammation in the target area
Acute inflammation indicates tissue damage and ongoing healing processes; applying aggressive lengthening techniques could further damage tissues and impair the healing process.
Q8When implementing dynamic stretching in a corrective exercise program, when is it most appropriately applied?
✓ Correct answer: A. During the integration phase
Dynamic stretching is most appropriate during the integration phase of corrective exercise as it involves movement-based stretching that prepares the body for the integrated movements to follow.
Q9Which of the following best describes the contract-relax PNF stretching technique?
✓ Correct answer: D. Isometric contraction of the target muscle followed by relaxation and increased stretch
The contract-relax PNF technique involves actively contracting the target muscle isometrically for 5-6 seconds, followed by a brief relaxation period, and then moving into a deeper stretch.
Q10What physiological adaptation occurs with consistent application of lengthening techniques over time?
✓ Correct answer: C. Increased sarcomere number in series
Regular application of lengthening techniques increases sarcomere number in series, a process called sarcomerogenesis, which allows the muscle to maintain force production over a greater functional range.
