NASM-CPT Exam Questions

Correct answer: The pressure within the arterial system following cardiac contraction

Systolic pressure, a critical component of blood pressure readings, represents the peak pressure in the arteries occurring immediately after the heart contracts and pumps blood out into the circulation.

This is the maximum pressure exerted against the arterial walls as the heart muscle contracts and forces blood through the circulatory system. Measuring systolic pressure is crucial for assessing the force your heart generates with each beat and is a vital indicator of cardiovascular health.

The pressure in the arterial system when the heart is at rest describes diastolic pressure, not systolic. Diastolic pressure is measured when the heart is in between beats and at rest. It represents the lowest level of arterial pressure during the relaxation phase of the cardiac cycle. In contrast, systolic pressure occurs when the heart is actively contracting, not at rest.

While arterial elasticity can affect blood pressure readings, it does not define what systolic pressure indicates. The elasticity of the arterial walls influences how the arteries respond to the pulse of blood with each heartbeat, but systolic pressure specifically measures the maximum force exerted during the heart's contraction phase.

The pressure in the arterial system when the heart is contracting while filling with blood is confusing and partially inaccurate, as it mixes phases of the cardiac cycle. The heart fills with blood during its relaxation phase (diastole), not during contraction (systole). Systolic pressure is measured when the heart muscle contracts and expels blood, not when it is filling.

Understanding systolic pressure and its measurement is essential for evaluating heart health and the risk of cardiovascular disease. Each incorrect answer misrepresents the conditions under which systolic pressure is assessed or confuses it with other physiological concepts.

Correct answer: Autogenic inhibition 

Self-myofascial release (SMR) is a technique used to help increase flexibility and range of motion. The idea is that when rolling, the individual should try to find tender spots to roll over. When a tender spot is found, then they simply relax the muscle, focus on deep breathing, and sustain pressure on that spot for at least 30 seconds. This will increase the Golgi tendon organ activity and decrease muscle spindle activity, thus triggering the autogenic inhibition response.

Reciprocal inhibition allows movement through the simultaneous contraction of one muscle and the relaxation of its antagonist.

Synergistic dominance occurs when inappropriate muscles take over the function of a weak or prime mover.

Pattern overload describes the repetitive process of the same pattern of motion, which may place abnormal stresses on the body.

Correct answer: Zone 3 uses a high HRmax to build high-end work capacity

Zone 3 is the most intense training zone; the average client will not be assessed with a resting heart rate that indicates the use of Zone 3 at the start of training.

Zone 1 is the baseline training zone, which supports recovery and builds endurance. Zone 2 intensifies endurance training and supports the growth of both aerobic and anaerobic fitness.

Correct answer: Social media

Self-confidence, also known as self-efficacy, supports exercise adherence. Fitness professionals should build their clients' confidence by creating an environment where performance accomplishments, modeling of the exercises, verbal persuasion, and self-imagery are used.

Also, giving praise to clients for their attempts at achieving goals may result in higher self-efficacy and greater levels of physical activity. This kind of positive feedback enhances confidence by focusing on small successes in the process.

Correct answer: "Why didn't you rate yourself lower?"

All the other questions suggest that the client is wrong. This question affirms that they are willing to make a change and puts the scenario in a positive light.

Correct answer: Floor bridge

Hypertension is a common medical disorder in which arterial blood pressure, if not controlled by medication, is high (resting systolic >140 mmHg or resting diastolic >90 mmHg). If sustained at a high enough level, hypertension can induce cardiovascular damage. However, research has shown that exercise can lower blood pressure.

Fitness professionals should monitor the body position of clients with hypertension at all times. Supine or prone positions such as floor bridge and floor prone cobra can increase blood pressure. 

Correct answer: When a muscle relaxes to allow another muscle to contract 

Reciprocal inhibition is a neuromuscular reflex that inhibits opposing muscles during movement. The concurrent contraction of one muscle (agonist) and the relaxation of another muscle (antagonist) allows movement to take place. It would be impossible to move if both an agonist and an antagonist contracted at the same time.

Length–tension relationship is defined as the amount of force that a muscle can produce at its existing length.

Neural activation is the response to stimuli that activates muscle movement.

The force-couple relationship is defined as muscle groups producing movement around a joint by moving simultaneously.

Correct answer: Increased metabolic rate

High-volume training, which involves performing a greater number of exercises, sets, and repetitions, is typically associated with an elevated metabolic rate. This type of training often leads to prolonged muscle exertion and increased energy expenditure, both during and after exercise (known as Excess Post-exercise Oxygen Consumption or EPOC). As the body works to recover from the stress of extended workouts, it continues to consume more oxygen and burn more calories than it would at rest, thereby increasing the overall metabolic rate. This adaptation helps improve the body's efficiency in energy utilization and fat burning, making it particularly beneficial for those looking to improve body composition and endurance.

The increased rate of force production is more closely associated with power training, which involves exercises that aim to maximize force output in the shortest possible time, often through lower volume but higher intensity workouts, such as sprinting or lifting heavy weights explosively. High-volume training typically focuses on endurance and muscle size rather than the quick force generation seen in power-oriented training. Therefore, while force production may improve slightly, it is not the primary adaptation expected from high-volume training.

High-volume training, contrary to reducing the anaerobic threshold, can actually help increase it when combined with appropriate intensity. The anaerobic threshold represents the point during exercise at which the body starts to produce lactic acid more rapidly than it can remove it. Training that involves prolonged or repeated stress on the muscles can lead to adaptations that improve the body’s ability to handle lactic acid, thus potentially raising the anaerobic threshold over time. Reduction in the anaerobic threshold is not a typical adaptation of high-volume training.

Increased motor unit synchronization, which refers to the coordinated activation of motor units to produce smoother and more efficient muscle contractions, is typically associated with skill-specific training or activities that require high levels of coordination and strength, such as Olympic weightlifting. While motor skills and coordination can improve with high-volume training, especially if the movements are complex, the primary adaptation is not as directly linked to motor unit synchronization as it is to metabolic enhancements.

High-volume training predominantly enhances the metabolic rate due to sustained and repeated muscle activity that demands increased energy expenditure. Other adaptations, such as increased force production and motor unit synchronization, are more characteristic of other training types that focus on power, strength, or neuromuscular efficiency.

Correct answer: Estimated maximal heart rate (HRmax) is calculated and then multiplied by the desired intensity percentage

The straight percentage method for calculating a client's Target Heart Rate (THR) involves a straightforward calculation where the estimated maximal Heart Rate (HRmax) is determined first, usually by subtracting the client's age from 220 (a commonly used formula to estimate HRmax). 

The result is then multiplied by the desired intensity percentage (typically ranging from about 50% to 85% depending on the fitness goals and health status of the individual). This method provides a target heart rate that guides the intensity at which the client should exercise to achieve cardiovascular benefits effectively.

The incorrect answers are explained as follows:

• The resting heart rate is subtracted from the maximal heart rate and then multiplied by the desired intensity: This description refers to the Karvonen formula, which is used to calculate the Heart Rate Reserve (HRR) by subtracting the resting heart rate from the maximal heart rate. The HRR is then multiplied by the desired intensity percentage and the resting heart rate is added back to find the THR. This method accounts for the individual's resting heart rate, which the straight percentage method does not, as it solely focuses on the HRmax.
• The maximal heart rate is divided by the desired intensity to establish the target heart rate: This method is incorrect because dividing the maximal heart rate by the desired intensity does not yield a meaningful or practical target heart rate. The division does not adhere to any standard practice in exercise physiology or fitness training. Instead, multiplication by the desired intensity factor (e.g., 0.7 for 70% intensity) is the correct approach to scale the HRmax down to a working target heart rate.
• The maximal heart rate is subtracted by the age of the client and then multiplied by the desired intensity: This answer confuses the initial calculation of HRmax with subsequent adjustments. The HRmax is typically estimated by subtracting the client's age from 220 (or using similar formulas), not by subtracting the age from the HRmax already calculated. Once HRmax is estimated, it should then be multiplied by the desired intensity; subtracting age at this point in the process is not only redundant but also incorrect, as it mixes two different aspects of heart rate calculations.

The straight percentage method relies solely on multiplying the estimated maximal heart rate by the desired intensity percentage to determine the target heart rate, providing a simple yet effective guideline for setting exercise intensity levels without taking into account the individual's resting heart rate. Other methods or misapplications of formulas result in inaccurate calculations not suited for practical fitness guidance.

Correct answer: The coordination of the nervous system and the muscular system with regard to force production and modulation

The nervous system and the muscular system are both responsible for our ability to move. If we lack any element of control over either of these systems, we tend to lose the ability to move with efficiency. When both systems are working at peak performance, we see improved coordination and force production/modulation throughout the body.

Correct answer: They cannot be produced by the body and must be acquired by food

Amino acids are the building blocks of proteins and can be divided into two main groups: essential amino acids and nonessential amino acids. Essential amino acids are those that cannot be made by the body and must be acquired by food; nonessential amino acids are sufficiently produced by the body and do not need to be consumed in dietary sources.

Correct answer: 30 or above

According to the body mass index (BMI) scale, a measurement within the range of 18.6–24.99 is considered normal. An individual with a BMI measurement of 30 or above is considered obese. BMI is not an indicator of health but is used as a general guideline for weight in relation to height.

Correct answer: Fat tissue is less conductive than muscle tissue

BIA operates on the principles of conductivity. Because fat tissue contains less water than muscle tissue, electrical impulses travel more slowly through fat than they do through muscle. This allows the BIA machine to estimate a person's body fat percentage. 

Correct answer: 3 to 5 repetitions 

While both the bench press and the squat test should be performed to failure in 2 to 10 repetitions, the most accurate prediction of one-repetition max strength comes from achieving failure between 3 and 5 repetitions.

For example, if a client fails at 3 repetitions, a much more accurate prediction from using a one-rep maximum estimation chart can be calculated.

Correct answer: Asthma

Asthma is not a cause of restrictive lung disease but rather an example of an obstructive lung disease. 

Obstructive lung diseases are characterized by a difficulty in expelling air from the lungs, leading to an obstruction of airflow. Asthma involves inflammation and narrowing of the airways, which restricts airflow during exhalation but does not necessarily affect the lung's ability to expand, which is a hallmark of restrictive lung diseases.

Restrictive lung diseases, on the other hand, are primarily characterized by a reduced lung volume or limited lung expansion, often due to changes in the lung tissue itself or due to external pressure or restrictions. 

Here's why the other listed options are indeed causes of restrictive lung disease:

• Obesity: Obesity can cause restrictive lung disease through a mechanical compression of the lungs and chest cavity. Excessive body fat, especially around the abdomen and chest, can limit the expansion of the lungs and diaphragm, thereby reducing lung capacity. This external restriction makes it difficult for individuals to fully inflate their lungs, fitting the definition of restrictive lung disease.
• Fractured ribs: Fractured ribs can severely impact lung function by causing pain during breathing, which often leads individuals to take shallow breaths to avoid discomfort. The limitation in lung expansion due to pain and mechanical restriction from the broken bones directly contributes to a restrictive lung pattern.
• A neuromuscular disease: Neuromuscular diseases, such as Amyotrophic Lateral Sclerosis (ALS) or muscular dystrophy, can lead to restrictive lung disease because they weaken the muscles involved in breathing. This muscle weakness impairs the ability of the respiratory system to expand and contract normally, thereby reducing lung capacity and restricting lung function.

Asthma is incorrectly grouped with causes of restrictive lung disease because its primary effect is obstructive, not restrictive. The other conditions listed—obesity, fractured ribs, and neuromuscular disease—directly impact the lung’s ability to expand, making them accurate examples of factors that can lead to restrictive lung disease.

Correct answer: A client's occupation indicates their movement patterns and alterations to posture, including extended periods of sitting, repetitive motions, and shoe/clothing requirements that restrict natural movement

Occupational demands and work history also provide valuable insight into potential conditions and concerns. Fitness professionals should inquire about these aspects of their client's work:

• Nature of the occupation
• Whether the job requires extended periods of sitting, repetitive motions, and shoe/clothing requirements that restrict natural movement
• Workspace environment

Occupation has no direct bearing on maximum fitness ability, chronic disease, or commitment to health improvement.

Correct answer: A system of promotion, transaction, and delivery of a product or service

Marketing encompasses much more than advertisement. It includes the development of solutions for the problems of clients and making those solutions accessible.

It is the process of promoting a service for the purpose of communicating the features, advantages, and benefits of personal training to potential clients.

Correct answer: Pre-contemplation

The Transtheoretical Model of Behavioral Change, also known as the Stages of Change Model, outlines a sequence of stages individuals typically progress through when changing a behavior. In the context of initiating physical activity, the individual described—exhibiting a complete lack of interest and acknowledgment of not considering exercise in their foreseeable future—most accurately falls into the pre-contemplation stage of this model.

In the pre-contemplation stage, individuals do not recognize any problem with their current behavior. They have no intention of changing this behavior in the near future (defined as within the next six months). People in this stage are often described as unaware or in denial about their need for change. For the scenario in question, the individual's total disinterest in initiating exercise and their explicit acknowledgment of not planning to start exercising align perfectly with the characteristics of the pre-contemplation stage.

The other stages are explained as follows:

• Contemplation: In the contemplation stage, individuals acknowledge that they have a problem and begin to think seriously about solving it. They intend to start the healthy behavior within the foreseeable future (within the next six months). However, they might be ambivalent toward change, weighing the pros and cons. In the given scenario, since the individual has not yet begun to consider exercise as a viable activity for their lifestyle, they have not reached this stage of considering change.
• Preparation: The preparation stage involves individuals who are ready to take action within the immediate future (typically the next month). They often start taking small steps toward the behavior change, such as researching gyms or buying exercise equipment. Since the described individual has not shown any interest in planning or preparing for physical activity, this stage does not apply.
• Action: In the action stage, individuals have recently changed their behavior (within the last six months) and intend to keep moving forward with that behavior change. Action is visible and requires considerable commitment and effort. The scenario presented does not fit this stage, as the individual has not initiated any form of exercise or indicated a move toward such action.

The described individual's stance on physical activity, marked by a lack of interest and absence of intention to engage in exercise, places them squarely in the pre-contemplation stage of the Transtheoretical Model of Behavioral Change. This stage precedes contemplation, preparation, and action, as it represents the very beginning of one's journey toward behavioral change, where the individual has yet to recognize the need or to develop the motivation to change.

Correct answer: Informational support

Informational support refers to the provision of advice, guidance, or knowledge to help someone understand and manage specific issues. In this scenario, the client is overwhelmed by conflicting information about weight loss. By explaining the scientific theories and evidence-based practices behind weight loss, the trainer is providing informational support, helping the client to sort through the misinformation and develop a clearer understanding of effective and healthy weight loss strategies.

Here’s why the other types of support, although potentially applicable in other aspects of personal training, are incorrect for this specific scenario:

• Emotional Support: This type of support involves offering empathy, concern, encouragement, and reassurance to help someone cope with stress or emotional challenges. While the trainer might naturally provide some level of emotional support simply by listening to the client's frustrations, the specific action of explaining weight loss theories does not constitute emotional support. The focus here is on providing factual information rather than addressing emotional needs.
• Motivational Support: Motivational support is aimed at boosting someone's motivation and encouragement to meet their goals. This could involve pep talks, setting incentives, or helping to establish achievable objectives. In this situation, while helping the client understand weight loss better could indirectly motivate them, the primary support being provided is educational or informational, rather than directly aimed at enhancing motivation.
• Behavioral support: Behavioral support focuses on helping someone change or manage their behaviors to achieve better outcomes, such as setting routines, monitoring progress, or providing feedback on actions. Although understanding the principles of weight loss might influence the client's behavior indirectly, the direct support described in the question is about transferring knowledge and understanding, not about managing or modifying behavior directly.

Informational support is the most accurate description of the trainer's assistance in this scenario, as it directly addresses the client's need for reliable and clear information to navigate the complexities of weight loss advice found online.

Correct answer: Degrees

Degrees are traditionally used to quantify a person's range of motion because they measure the angle through which a joint can move between its position of full extension and full flexion. This unit of measure allows health professionals, fitness trainers, and researchers to accurately gauge and compare the flexibility and joint health of individuals. Using degrees provides a clear and standardized way to document the arc or range through which each joint can move, which is crucial for assessing mobility, designing rehabilitation programs, and tracking progress over time.

Newtons are a unit of force in the International System of Units (SI). They measure the force exerted on an object, not the movement or flexibility of joints. Newtons would be relevant in contexts where the physical force applied by or on a part of the body is being measured, such as in biomechanics to assess muscle strength or in physical therapy when applying resistance training. They do not provide information about the extent of joint movement, which is what range of motion measurements aim to capture.

Millimeters are a unit of length used to measure distance but are not appropriate for quantifying range of motion. While millimeters or centimeters might be used to measure the displacement or movement of a limb along a straight path (like how far a knee can rise or an arm can stretch), they cannot adequately describe the angular movement around a joint. Range of motion is about angles and rotational movement, which is best expressed in degrees.

Revolutions Per Minute (RPMs) measure the number of complete rotations or cycles completed by a rotating object per minute and are commonly used in the context of rotational speeds, such as in engines or other machinery. In the context of human joints and range of motion, RPMs would be irrelevant because human joint movements in a clinical or fitness setting are not rotational in nature like machinery. Instead, they involve angles of joint opening and closing that are static per movement, not cyclical or continuous rotations per minute.

Degrees are the most appropriate and traditional unit for quantifying a person's range of motion, as they accurately reflect the angular nature of joint movements. Units like Newtons, millimeters, and RPMs do not align with the measurement needs of joint flexibility and mobility since they pertain to force, linear distance, and rotational speed, respectively.
