Which statement best describes the first stage of the sales process?
Identifying a customer’s needs.
Which of the following structures is important for muscle contractions by providing a binding site?
Troponin
Which component contributes the most to total energy expenditure?
Resting metabolism
Which heart chamber receives oxygenated blood and pumps it to the body?
Left ventricle
Which lower-body stretch is considered controversial and may be a risk for injury?
Assisted supine hamstring stretch
Which muscles are typically underactive with knee valgus during the single-leg squat?
Gluteus maximus and medius
Most bodyweight exercises are considered which type of movement?
Closed-chain exercise
What measurement is dependent upon the length of the lever arm and the angle between the force application and the lever arm?
Torque
Researchers have found that myofascial rolling can decrease the effects of what condition after strenuous exercise?
Delayed-onset muscle soreness
What is the recommended frequency for cardiorespiratory training if participating in moderate-intensity exercise like brisk walking?
5 times a week
What are the end products of the electron transport chain?
ATP and water (NAD+, FAD, and protons)
How should an eccentric muscle action be described?
The development of muscle tension during lengthening of the contractile tissue.
What is the function of the neuromuscular junction?
Why is avoiding all sources of fat a detrimental dietary strategy?
Some fats are essential and required in the diet for important physiological processes. Avoiding all fats might lead to deficiencies.
You have a client seeking weight loss. What range of sets is most appropriate for SAQ drills?
3 or 4 sets.
Which heart chamber gathers oxygenated blood coming to the heart from the lungs?
Left atrium
What phase of the OPT model aims to increase maximal strength and rate of force production?
Power Training
What structure in the heart transfers the electrical signal from the sinoatrial (SA) node to the atrioventricular (AV) node?
Internodal pathway
What depth is suggested for the overhead squat assessment?
Femur parallel to ground
When progressing a client to more-dynamic plyometric exercises, what is the first element that should be increased?
Stabilization, form, and mechanics during landing
Which component of SAQ involves the ability to react to a stimulus (i.e., reaction time) and appropriately change the motion of the body in response to that stimulus (such as hitting a baseball)?
Quickness
The development of muscular endurance of the legs requires light weight and high repetitions when performing leg-related exercises. What is this an example of?
Mechanical specificity.
Flexibility training can reduce the risk of what three conditions?
Muscle imbalances, joint dysfunctions, and overuse injuries.
What is adaptive thermogenesis?
Metabolic adaptations and changes in energy expenditure due to changes in energy intake
