NCCPT Exercise Technique and Instruction Questions and Answers — Questions and Answers
Question 1: A trainer is spotting a client during a barbell back squat. The client begins to fail midway through the concentric (upward) phase of the lift. What is the most appropriate action for the trainer to take?
- Grab the bar from behind and assist in re-racking it.
- Stand in front of the client and pull them up by their arms.
- Assist the client by placing hands under their torso/hips and guiding them upward. (Correct answer)
- Encourage the client to drop the weight behind them.
Correct answer: Assist the client by placing hands under their torso/hips and guiding them upward.
The correct procedure for spotting a back squat is to stand behind the lifter and follow their movement. If they fail, the spotter should secure their arms around the client's torso, under their armpits, and use their own legs to help guide the lifter up to a standing position where the bar can be safely re-racked. Grabbing the bar is dangerous as it can disrupt the lifter's balance.
Question 2: During a conventional barbell deadlift, which of the following represents the MOST critical form error that significantly increases shear forces on the lumbar spine?
- Flexion of the lumbar spine during the initial pull from the floor. (Correct answer)
- Failing to achieve full hip extension at the top of the movement.
- Looking straight ahead instead of keeping a neutral cervical spine.
- Performing the movement too quickly.
Correct answer: Flexion of the lumbar spine during the initial pull from the floor.
Lumbar flexion, or rounding of the lower back, under a heavy load is the primary mechanism for disc-related injuries in the deadlift. Maintaining a neutral spine throughout the lift is crucial for distributing the force safely across the vertebral column.
Question 3: A trainer observes a client's knees caving inward (knee valgus) during a bodyweight squat. To correct this, the trainer says, "Imagine you are spreading the floor apart with your feet." This is an example of what type of cue?
- Internal
- Tactile
- Kinesthetic
- External (Correct answer)
Correct answer: External
An external cue directs the client's focus to the outcome of their movement on the environment (e.g., "spreading the floor"). Research suggests this is often more effective for motor learning than an internal cue, which focuses on a specific body part (e.g., "push your knees out").
Question 4: An experienced client is preparing to perform a one-repetition maximum (1RM) attempt on the bench press. The trainer advises them to take a deep breath, hold it while lowering the bar, and begin forcefully exhaling past the most difficult point of the lift. This technique is known as what?
- Diaphragmatic Pacing
- The Valsalva Maneuver (Correct answer)
- Anatomical Breathing
- Hypopressive Breathing
Correct answer: The Valsalva Maneuver
The Valsalva maneuver is the process of expiring against a closed glottis, which increases intra-abdominal and intrathoracic pressure. This creates a rigid torso, stabilizing the spine and improving force production during maximal effort lifts.
Question 5: A new client is unable to perform a standard push-up with proper form, exhibiting significant lumbar sagging. Which of the following is the MOST appropriate regression for this exercise?
- Performing the push-up on their fists instead of flat palms.
- Placing a resistance band around their hips, anchored from above.
- Elevating their hands on a stable box or bench. (Correct answer)
- Increasing the speed of the repetitions.
Correct answer: Elevating their hands on a stable box or bench.
Elevating the hands on a stable surface, such as a box or bench, reduces the percentage of body weight the client must lift. This makes the exercise easier, allowing them to focus on maintaining a neutral spine and proper core engagement before progressing to a full push-up.
Question 6: When instructing a client on a lat pulldown, the trainer explains that switching from a wide, pronated (overhand) grip to a narrow, supinated (underhand) grip will result in what change in muscle involvement?
- Increased involvement of the biceps brachii and a different angle of pull on the latissimus dorsi. (Correct answer)
- Decreased involvement of the latissimus dorsi and increased involvement of the trapezius.
- A complete shift of the workload from the back muscles to the chest muscles.
- Increased activation of the rhomboids and decreased activation of the biceps brachii.
Correct answer: Increased involvement of the biceps brachii and a different angle of pull on the latissimus dorsi.
A supinated (underhand) grip places the biceps brachii in a more biomechanically advantageous position for pulling, thus increasing its contribution to the movement. While the latissimus dorsi is still the primary mover, the narrower grip and supinated hand position alter the angle of pull, often emphasizing the lower fibers of the lats.
