Which of the following activities requires approximately 3.5 mL of oxygen per kg of body weight per minute?
Rest
Moderate resistance squats
Light bike riding
Plyometric exercises
Max intensity sprints
Rest:
is the correct answer as the body requires a VO2 of 3.5 ml/kg/min to maintain resting metabolism.
A metabolic equipment, or MET is simple method of expressing exercise intensity relative to rest.
One MET is equal to resting metabolic:
[3.5 ml/kg/min].
Light bike riding: is incorrect. Any activity that is higher intensity than rest wil require a greater oxygen consumption.
Therefore the VO2 of light bike riding is greater than 3.5 ml/kg/min.
Moderate resistance squats: is incorrect. It is a higher intensity than rest and requires more than 1 MET.
Max intensity sprints: is incorrect. Greater than 3.5 ml/kg/min of VO2 is required to perform activity.
Plyometric exercises are incorrect. They are a high intensity activity requiring greater than one MET of VO2.
Which theory of behavior change puts an emphasis on the client’s thoughts and feelings?
Theory of planned behavior
Health belief model
Transtheoretical model
Social cognitive theory
Behavior choice model
Social cognitive theory:
is correct because this model focuses on how clients shape their lives by thinking, feeling, reflecting and observing themselves.
Social cognitive theory states that outcome expectations and self-efficacy are the most important factors in behavior change.
These factors each have environmental and personal aspects.
Theory of planned behavior: is incorrect because this focuses on client’s attitude.
Health belief model: is incorrect because this focuses on the consequences of health and disease.
Transtheoretical model: is incorrect because this focuses on client’s readiness to change.
Behavior choice model: is incorrect because this is not a real model.
Which of the following is not a factor in the relative contribution of aerobic and anaerobic metabolism during exercise?
Stroke volume
Muscle capillary density
Ventilation
None of these
Intensity of activity
None of these:
is incorrect. The ability to utilize oxygen depends on it’s delivery [cardiac output, hemoglobin concentration], exchange at the lungs [ventilation], and extraction and utilitzation at the working muscles [capillary, myoglobin and mitochondrial density].
These factors must also be able to meet the energy demands [intensity] of the activity.
Stroke volume: isincorrect. This is the amount of blood pumped per heart beat and play a direct relationship with the amount of oxygen, that is carried in the blood, that can be delivered to the working tissues and allow the contribution of aerobic metabolism to increase.
Intensity of activity: is incorrect. This determines the amount of energy that is required, and if greater than what can be provided by aerobic metabolism will determine the amount of anaerobic metabolism that is required.
Ventilation: is incorrect. This factors into the amount of oxygen that can be deliverd via the bloodstream to be made available for aerobic metabolism.
Muscle capillary density: is incorrect. This factor is related to how much oxygen can be exchange between the blood vessels and the working muscle.
What nutrient plays a significant role in satiety control
Fat
Iron
Water
Vitamin D
Carbohydrate
Fat:
is correct because fat stays in the stomach longer than other nutrients.
This allows people to feel fuller for longer.
This makes fat an important nutrient to consider when working with weight loss clients.
Vitamin D: is incorrect because this nutrient improve bone health.
Carbs: is incorrect because this is the main energy source.
Water: is incorrect because this nutrient controls fluid balance and temperature.
Iron: is incorrect because this nutrient aids oxygen carrying capacity.
What is the main function of carbs in the body?
Provides energy for the body
Aids in absorption of various nutrients in the body
Provides building blocks for various tissues of the body
Provides enzymes for the various functions of the body
Aids in digestion of various nutrients in the body
Provides energy for the body:
is correct because carbs can easily be broken down to use in multiple energy systems.
Carbs are compounds that contain carbon, hydrogen and oxygen.
They are classified as simple [sugars], complex [starches] and fibers.
Provides building blocks for various tissues of the body and Provides enzymes for the various functions of the body: is incorrect because this is the main function of protein.
Aids in absorption of various nutrients in the body: is incorrect because this is a function of another nutrient.
Aids in digestion of various nutrients in the body: is incorrect because this is a function of fat.
Which strategy of designing training programs involves systematic variation of the training parameters in order to maximize their effect?
Variable planning
Cyclization
Qualitative planning
Periodization
Linearalization
Periodization:
is correct because this is the planned distribution or variation in training means and methods on a periodic or cyclic basis.
The variables manipulated at each level of planning include exercise [or work] intervals, exercise order, exercise/relief, frequency, intensity, relief or recovery [or rest] interval, repetition, series, set and volume.
Periodization is largely based on Selye’s work on the manner in which the human body reacts to stress, which he describes as the General Adaptation Syndrome [GAS].
Cyclization: is incorrect because this is the incorrect term.
Variable planning: is incorrect because this does not denote a systematic variation in training parameters.
Qualitative planning: is incorrect because there is a quantitative aspect to training programs as well.
Linearalization: is incorrect because not all periodization is linear in nature.
The study of motion and the causes of motion on the human body is known as which of the following areas of knowledge?
Anatomy
Physiology
Exercise science
Biomechanics
Kinesiology
Biomechanics:
is correct because this field of knowledge helps provide insight on bodily motion and the causes behind these motions.
Biomechanics is important to promote safe and effective exercise technique and to decrease risk by increasing injury prevention.
Kinesiology: is incorrect because although it includes biomechanics, it also takes into consideration the neural and cardiovascular aspects as well.
Physiology: is incorrect because this is the function of a living organism and its parts.
Exercise science: is incorrect because this includes not only biomechanics but physiology, motor control and other aspects as well.
Anatomy: is incorrect because this is the study of the structure and location of the organs, tissues and cells of the body.
Training that emulates movements during one’s everyday life is called which of the following?
Anaerobic training
Functiinal training
Plyometrics
Flexibility training
Core training
Functional training:
is correct because this includes exercises that mimic everyday activities.
It is designed to help train individuals to better perform their everyday tasks and movements.
Trainers would focus on exercises that would help improve job-related functions such as lifting heavy objects from the floor, or improve daily chores such as carrying laundry baskets.
Anaerobic training: is incorrect because this training focuses solely on high intensity activities.
Plyometrics: is incorrect because this is designed to improve power and speed.
Core training: is incorrect because this training focuses on one area of the body.
Flexibility training: is incorrect because this is designed to increase elasticity and length of the muscular system.
In addition to hand position, what other factor is important in determining grip?
Reducing hand moisture prior to the exercise
Maintaining max grip strength
All of these
Unsing a hook grip
Placing the hands at the appropriated distance from each other
Placing the hands at the appropriated distance from each other:
is correct because hand position should result in a balanced, even bar.
Grip width refers to the distance of each hand to the other and can be either common, wide and narrow.
For most exercises, correct placement is approximately shoulder-width apart.
Reducing hand moisture prior to the exercise: is incorrect because this may not always be needed.
Maintaining max grip strength: is incorrect because this may useless if the hands are placed inappropriately on a bar.
Unsing a hook grip: is incorrect because this grip is only appropriate for certain exercises.
Which of the following is not a benefit of eating many, small meals for a client whose goal is fat loss?
Increased lipid burning enzymes
Controlled hunger
Minimized blood sugar fluctuations
Decreased stress hormone production
Increased energy levels throughout the day
Increased lipid burning enzymes:
is correct because this is not achieved by eating smaller, more frequent meals.
Benefits of this regime include metabolic rate maintenance, increased glucose tolerance, fewer blood sugar fluctuations, increased muscle mass maintenance, increased daily performance and energy levels and better ability to control hunger.
All other options offered are incorrect because they are benefits of eating many small meals throughout the day.
Which of the following is the most accurate method for a client to measure their training stress?
Work-load
Workload tolerance
Volume-load
Repetition volume
Energy cost
Volume load:
is correct because this includes both amount of stress and the intensity of the stress.
There will be a lower end, the stimulus threshold necessary to trigger the desired effects and an upper end, the point of diminishing returns.
Beyond that latter point, further application will not serve a beneficial purpose and may in fact be harmful.
Work-load: is incorrect because this doesn’t include volume and intensity.
Workload tolerance: is incorrect because this is not a calculation of applied stress.
Energy cost: is incorrect because this is only measuring the amount of stress, not how that stress is applied.
Repetition volume: is incorrect because this doesn’t account for the intensity of the stress.
What is the purpose of a waiver or release of liability document for a personal trainer?
To protect the liability of the trainer in case of injury in transit to facility
To protect the liability of the trainer in case lack of results
None of these
To protect the liability of the trainer in case of equipment failure
To protect the liability of the trainer in case of negligence
To protect the liability of the trainer in case of negligence:
is correct because a waiver or release of liability document is designed for the client to knowingly waive or release the personal trainer of liability from any acts of negligence.
The type of documentation needed is dependent on the state of practice, and consultation with and attorney may be warranted to ensure protection.
The other options are incorrect because they don’t fall on they responsibility of a personal trainer. [In the case of equipment failure: only if trainer neglected to maintain the equipment].
What should a trainer do before offerng to spot their client?
Properly set up equipment
All of these
Demonstrate the exercise to be performed
Ask if they can touch the client
All of these:
is correct because they all relate to establishing trust, communication and a safe environment with a client.
A trainer should always ask the client if it is acceptable to touch during a spot.
Additionally, a trainer must ensure that the machine is accurately set up fo the client and that the client has been properly informed how to perform the exercise.
All other options offered are incorrect because individually, they are only a part of the whole answer.
Which of the following is not a method of reducing risk when using weight machines for exercise?
Documenting the weight, number of sets and number of repetitons for the client
Give the client proper instructions and supervision
Perform regular maintenance on the equipment
Progressing the intensity every exercise session
Inspect the equipment before use
Progressing the intensity every exercise session:
is correct because this is a common cause of injury.
Progression should occur through following a conservative plan to increase intensity in communication with the client.
Weight machines carry a reduced risk of injury because the client’s body is more stable and movement is more restricted than with free weights.
All other options offered are incorrect because they either reduce risk and decrease incidence of injury.
Which of the following terms describes a trainer who owns their own company but still works as a PT fo a 3rd party?
Independent contractor
Sole proprietor
Business partner
Full-time employee
Fitness manager
Independent contractor:
is correct because this indicates that this PT is not a full-fledged employee of the company, despite performing some work for them.
As a trainer, there are several different models for starting your own business.
You can be the sole owner of your training company but work as an independent contractor for a gym that sets your schedule and decides how frequently you work.
The other options are incorrect because they either, don’t own their own company, are a full-time employee or working for a 3rd party company.
