What does a ‘spot’ mean during a resistance exercise?
A position in the ROM
How to lift
Assistance with an exercise
The grip
Where to lift
Assistance with an exercise: is correct because this includes aiding the lifter when they cannot complete the repetition.
Note: Spotting is another responsibility of the trainer when a client is performing resistance exercises.
Note: A trainer should know how to properly spot a client to prevent any injuries.
Where to lift: is incorrect because it does not refer to assisting the lifter during the exercise.
How to lift: is incorrect because this is referred to an instruction of demonstration.
A position in ROM: is incorrect because this is not involved with assisting an exercise.
The grip: is incorrect because this is part of the technique.
A strain is an injury to which of the following structures of the body?
Bone
Heart
Blood vessel
Ligament
Muscle or tendon
Muscle or tendon: is correct because this involves the stretching or tearing of one or both of these structures.
Note: strains are often caused by an over-stretching of the muscle or tendon and is characterized by local stiffness, discoloration and bruising.
Note: a strain is also known as a pulled muscle.
Ligament: is incorrect because a similar injury to this structure is known as a strain.
Bone: is incorrect because an injury to this structure is known as a fracture or break.
Blood vessel: is incorrect because an injury to this structure is a contustion or hematoma.
Heart: is incorrect because an injury to this structure is much more serious than a strain.
Which of the following is shortened during a concentric muscle contraction?
Length of myosin filaments
Lenth of the tendon
Myosin-actin cross-bridge
Length of sarcomere
Length of actin filaments
The sliding filament theory discribes how the thick [myosin] and thin [actin] filaments pull across one another in order to shorten the muscle. The functional units of a muscle are sarcomeres, which are separated by Z lines, upon which actin filaments are attached. During concentric contractions the Z lines move together, thus decreasing the length of the sarcomere.
The length of actin filaments remain constant throughout any muscle contraction. Therefore this answer is incorrect.
Length of myosin filaments: is incorrect. This is not altered during any muscle contraction.
The myosin-actin cross-bridge: is active and pulls actin and myosin and actin across each other during a concentric contraction. However, it does not shorten and is incorrect.
The length of the tendon: is incorrect. A tendon is a connective tissue that does not chage shape during any muscle contraction.
What is the ideal maximum number, in millimeters, for systolic blood pressure?
80
120
150
160
200
120: is correct because pressure exceeding this systolic range run the risk of hypertention.
Note: Systolic blood pressure represents the pressure exerted on the arterial wall during the ventricles’ contraction phase.
Note: A normal distolic [blood pressure during ventricle relaxation] is 80 mm Hg.
150: is incorrect because this would indicate hypertension.
160: is incorrect because this is much too high.
200: is incorrect because this number would typically only be seen during maximal exertion.
80: is incorrect because this is too low and represents a normal distolic blood pressure.
Which of the following movements occurs in the transverse plane?
Extension
Flexion
Horizontal abduction
Abduction
Adduction
Horizontal abduction: is correct. The transverse plane separates the body into upper and lower halves. Movement in this plane will occur around a vertical, or longitudinal, axis and are rotational.
Note: examples of transverse plane movements include horizontal abduction, horizontal adduction, internal rotation and external rotation.
Flexion and extension are incorrect as these movements occur in the sagittal plane.
Abduction and adduction: are incorrect because these movements occur in the frontal plane.
A client discovers that they have a nutrient and mineral deficiency, which situation most likely lead to this?
Low caloric intake
Eating a variety of foods
Eating a vegetarian diet
Not enough fruit consumption
Not consuming any dairy product
Low caloric intake: is correct because the average individual consuming an average diet will not have any nutrient deficiencies. When caloric intake is too low, the consumption of the vitamins and minerals will be too low.
Note: this is a major reason why clients must be cautious when consuming a low calorie diet.
Eating a variety of foods: is incorrect because this is more likely to lead to an abundance of vitamins and minerals.
Not enough fruit consumption: is incorrect because vitamins and minerals can be obtained from other sources.
Eating a vegetarian diet: is incorrect because this diet can obtain all needed vitamins and minerals.
Not consuming any dairy products: is incorrect because this diet does not necessarily lead to any deficiencies.
Which two nutrients aid in maintaining the fluid balance of the body?
Protein and fat
Fat and carbohydrate
Water and carbohydrate
Water and fat
Water and protein
Water and protein: is correct because water provides the body with fluid and protein helps control the fluid balance between the blood and surrounding tissues.
Note: protein is also involved in the growth and maintenance of all the body’s tissues and cells.
Note: water also aids in temperature regulation.
Water and carbohydrate: is incorrect because carbohydrate is not involved in fluid balance.
Protein and fat: is incorrect because fat is not involved in fluid balance.
Fat and carbohydrate: is incorrect because neither nutrient aids in body fluid balance.
Water and fat: is incorrect because body fluid balance is not maintained by fat.
A decrease in exercise performance can occur with a loss of how much fluid?
4% of body weight
2% of body weight
1% of body weight
8% of body weight
6% of body weight
2% of body weight: is correct because research has shown this amount to decrease and adversely affect circulatory function.
Note: hydration of the body is important for body temperature regulation, transporting nutrients and waste to and from cells and lubrication.
4% of body weight: is incorrect because this much loss would result in severe complications.
1% of body weight: is incorrect because this amount is too low.
6% of body weight: is incorrect because this is considered almost fatal dehydration.
8% of body weight: is incorrect because this amount of fluid loss is likely to result in death.
Which of the following muscles is not involved in respiration during high intensity exercise?
Internal obliques
Diaphram
External intercostals
Pectoralis major
Rectus abdominis
The correct answer is pectoralis major.
During respiration (at rest), the diaphram is the only muscle needed for inspiration, and expiration can occur through relaxing this muscle.
During forceful respiration, like during high intensity exercise, the external intercostals** aid in inspiration, and the internal intercostals and abdominal muscles [**rectus abdominis**, **internal obliques** and **external intercostals and transverse abdominis] aid in exhalation.
Diaphram is incorrect. This is the only muscle needed to breathe at rest and is only involved with forceful breathing during high intensity exercise.
Rectus abdominis is incorrect. This abdominal muscle aids expiration during high intensity exercise.
External intercostals incorrect. Forceful inspiration during exercise is aided by this muscle.
Internal obliques is incorrect. This abdominal muscles aids forceful expiration.
Which factor related to adherence involves the planning, organizing, and tracking of physical activity?
Self-regulation
Self-worth
Social support
Sef-efficacy
Motivation
Self-regulation: because this tasks that the surrounding physical activity will aid in maintaining a regime.
As a personal trainer, a large portion of the job is to equip clients with the skills necessary to adhere to exercise.
Note: adherence is important because approximately 50% of people who begin an exercise program drop out within the first six months.
Social support: is incorrect because this factor involves the desire to perform physical activity.
Social support: is incorrect because this factor involves exchange of aid or assistance among individuals or groups.
Self-worth: is incorrect because this is the satisfaction an individual has with themselves.
Self-efficacy: is incorrect because this involves an individual’s confidence.
Exercise self-regulation includes all of these for a client except which of the following strategies?
Encourage excluding distracting friends from exercise
Manage schedule to exercise
Provide exercise back-up plans
Identify a variety a ways to exercise
Plan workouts before exercise
Encourage excluding distracting friends from exercise: is correct because this is the opposite strategy a personal trainer would use to improve a client’s exercise self-regulation.
Note: exercise self-regulation strategies include planning exercise, setting exercise related goals, self-monitoring exercise behavior and avoiding relapse.
Note: all of these increase exercise adherence.
Which is lacking in a client’s goal of “eating more daily vegetables for the next month?”
Not attainable
Not specific enough
Not measurable
Not realistic
Not timely
Not specific enough: is correct because it lacks a detailed description of what is to be accomplished.
The most effective goals follow the SMART principle.
Note: the goals are specific, measurable, attainable, realistic, and timely.
e.g. “eating five servings of vegetables daily for the next month.”
Not measurable: is incorrect because this goal can be measured.
Not timely: is incorrect because the time frame is given.
Not realistic: is incorrect because this goal can be accomplished.
Not attainable: is incorrect because this goal can be achieved.
Which of the following is not necessary to make a good impression with a perspective client?
Smile
Appear neat, clean and well dressed
Make eye contact
Call the client “sir” or “ma’am”
Use the client’s name
Call the client “sir” or “ma’am”: is correct because this may be too formal for the relationship a personal trainer is looking to develop with a client.
Note: developing rapport with a client is of the up most importance, and making a good impression is a part of that.
Make eye contact: is incorrect because this is an excellent way to make a good first impression.
Smile: is incorrect because this is important for developing rapport.
Use the client’s name: is incorrect because this is important for making a good first impression.
What is the best type, that is recommended by ACSM, of behavioral goal to set to achieve results?
GOAL
SACSM
SMART
TRAMS
SAMCRO
SMART: is correct because these goals set targets for reasonable and traceable behaviours and provide a path and time line for achievement.
SMART: specific, measurable, attainable, realistic and timely.
Note: this is ACSM’s system for setting appropriate behavioral goals that clients can accomplish.
SAMCRO: is incorrect because this is a fictional motorcycle club in a fictional televison show.
SACSM: is incorrect because it is a study and action course in staff management.
TRAMS: is incorrect because this is the pleural of a streetcar.
GOAL: is incorrect because this is a target that is trying to be achieved.
Why is it important to know a client’s exercise history?
To determine if they are worth your time
To determine if the client has any cardiovascular disease risk factors
To recycle their old training program
None of these
To assess their laziness
None of these: is correct because the correct answer isn’t given as an option.
A client’s exercise history is important because it shows what they have been able to do, whether they can move on to advanced exercises, and what their attitude is toward exercise is in general.
Note:
this is an important piece to determining risk for the client.
To assess theit laziness:
is incorrect because this has no bearing on client safety.
To recycle their old training program:
is incorrect because this is not what should occur.
To determine if they are worth your time:
is incorrect because every client is worth your time.
To determine if the client has any cardiovascular disease risk factors:
is incorrect because this information could not be obtained from an exercise history.
