226 - 250 Flashcards
In the very late stages of a marathon when speed is increased to finish, which macronutrient usage is enhanced to become the primary energy source?
Fat
Water
Protein
Carbohydrate
Vitamins
Carbohydrate:
is correct because once the exercise intensity increases, the contribution of fats decreases due to the increasing role of carbohydrates due to increased need for a instantaneous fuel source.
The fuel source that is used is dependant on duration [it takes time for fat oxidation to increase] and intensity.
Protein: is incorrect as this substrate is only used when fat or carbohydrate is unavailable.
Fat: is incorrect because this substrate is not a primary energy source when exercise intensity is high.
Vitamins: is incorrect because this is not an energy substrate.
Water: is incorrect because this is not an energy substrate.
Which stage of readiness to change is characterized by change being planned within the next 6 months?
Action
Maintenance
Preparation
Pre-contemplation
Contemplation
Contemplation:
is correct because at this point, the client is understanding the negative consequences of their current behavior.
It means that a client recognizes the importance of the change, wants to do it at some point, but is not ready to put it into action or even begin preparing for it in the immediate future.
Action: is incorrect because the client is currently pursuing a behavior change in this stage.
Maintenance: is incorrect because the client has already performed the new behavioir for at least six months is this stage.
Preparation: is incorrect because this stage is characterized by the client making changes in the immediate future.
Pre-contemplation: is incorrect because in this stage the client is not fully aware of the negative consequences of their behavior.
During his initial consultation, the client informs you that he is currently using beta blockers. What physiological result would be expected during the physiological assessment?
Increased maximal oxygen intake
Decreased strength
Increased joint laxity
Decreased heart rate
Increased blood pressure
Decreased heart rate:
is correct because they will decrease both heart rate and blood pressure.
Clients seeking personal training services may be under the care of a physician and taking one or more prescribed medications.
While it is far from the role of the personal trainer to prescribe, manage or educated clients on prescription usage, understanding which medications are being taken and how they may affect the client’s physiological functioning is important.
Increased blood pressure: is incorrect because beta blockers decrease blood pressure.
Increased maximal oxygen intake: is incorrect because this is not a function of beta blockers.
Decreased strength: is incorrect because this is not a consequence of beta blockers.
Increased joint laxity: is incorrect because this is not a consequence of beta blockers.
Which combination of micronutrients is very important for the bone health of an elderly population?
Calcium and vitamin B6
Calcium and vitamin C
Calcium and vitamin D
Zinc and vitamin D
Calcium and Co-Enzyme Q10
Calcium and vitamin D:
is correct because they are important to bone health especially in the elderly population.
Calcium plays an important part in muscle contractions, nerve impulses, regulation of blood pressure, immune function, energy and fat metabolism. Vitamin D also has important immune functions.
Calcium and vitamin B6: is incorrect because vitamin B6 is not related to bone health.
Calcium and vitamin C: is incorrect because vitamin C is not related to bone health.
Calcium and Co-Enzyme Q10: is incorrect because this co-enzyme is not related to bone health.
Zinc and vitamin D: is incorrect because zink is not related to bone health.
How long should you wait before reading the calipers in a skinfold measurement assessment after pinching them on the skin?
5 seconds
Should read immediately
1 minute
30 seconds
1 to 2 seconds
1 to 2 seconds:
is correct because this allows the pinched skin to settle, which will provide a more accurate reading.
Skinfold measurements are used to determine body composition.
When performed by a skilled technician thsi method is very accurate.
1 minute: is incorrect because this would provide a very inaccurate reading.
5 seconds: is incorrect because this may be to long and allow the subcutaneous fat to be compressed or move from the caliper’s grip.
30 seconds: is incorrect because this would provide a very inaccurate reading.
Should read immediately: is incorrect because waiting for a brief time [1 to 2 seconds] allows the pinched skin to settle, which will provide a more accurate reading.
When manually recording a client’s pulse, where is the preferred location of measurement?
Hip
Neck
Ankle
Chest
Wrist
Wrist:
is correct because it is safe, non-invasive and easy.
Measuring one’s pulse by feeling the pulsating blood through the arteries is a simple method of manually determining heart rate.
Determining resting heart rate is a fairly good indicator of overall fitness, and measuring heart rate during exercise can give the personal trainer insight into how the client is responding to stress.
The neck: is incorrect because this is not as safe or accurate as a wrist measurement.
The chest: is incorrect because it is not possible to manually determine heart rate accurately at this location.
The ankle: is incorrect because it is not possible to manually determine heart rate accurately at this location.
The hip: is incorrect because it is not possible to manually determine heart rate accurately at this location.
Which of the following findings during a client consultation would indicate that someone is at moderate risk before beginning an exercise program?
A family history of atheroscelerosis and walks to and from work daily
30 years old and a BMI of 36
Does not currently exercise and has a family history of heart attacks
Smoked for four years and BMI of 18
75 years old and a widow
Does not currently exercise and has a family history of heart attacks:
is correct because moderate risk is defined as having two or more risk factors for cardiovascular disease without having known cardiovascular, pulmomary or metabolic disease and without having major signs or symptoms of these diseases.
The risk factors of cardiovascular disease are family history, age, cigarette smoking, obesity, sedantary lifestyle hypertendsion, dyslipidemia and prediabetes.
Smoked for four years and BMI of 18: is incorrect because this includes only one risk factor, a BMI of 18 is considered normal.
75 years old and a widow: is incorrect because age is the only risk factor.
A family history of atheroscelerosis and walks to and from work daily: is incorrect because family history is the only risk factor.
30 years old and a BMI of 36: is incorrect because obesity is the only risk factor.
The 1.5 mile includes which of the following as a contraindication of performing the test?
Unable to jog continuously for fifteen minutes
Individuals with a medical clearance
Those whose BMI considers them overweight
No known heart disease
Individuals who have exercised for only three to six months
Unable to jog continuously for fifteen minutes:
is correct because the ability to perform the test is dependent on performing moderate intensity exercise for approximately fifteen minutes.
The 1.5 mile run test is a field test of cardiorespiratory fitness.
It has been shown to be able to predict VO2 max with relative accuracy.
No known heart disease: is inorrect because this does not exclude an individual from performing the test.
Individuals who have exercised for only three to six months: is inorrect because this individual should be able to perform the test.
Individuals with a medical clearance: is inorrect because this indicates that a medical professional has permitted the test.
Those whose BMI considers them overweight: is inorrect because being overweight, on its own does not exclude one from the test.
What is the anatomical term for low blood pressure?
Hyponatremia
Hyperglycemia
Insulitis
Glycemic index
Hypoglycemia
Hypoglycemia:
is correct because ‘hypo’ refers to something that is low or decreasing, and ‘glycemia’ refers both to glycogen or sugar and emia which refers to blood.
Low levels of blood sugar or hypoglycemia, is just as dangerous to an individual as when their blood sugar levels are beyond the recommened ceiling or hyperglycemia.
A trainer must be able to recognize symptoms of these conditions and know how to respond in case of emergency.
Hyperglycemia: is incorrect because it refers to high blood sugar.
Insulitis: is incorrect because this is a condition of pancreatic cells related to diabetes.
Glycemic index: is incorrect because this is the amount that a food will raise blood sugar.
Hyponatremia: is incorrect because this is a dangerous decrease in plasma sodium levels.
Which two health issues does the PAR-Q focus on as a pre-preparation screen?
Lung disease and musculoskeletal problems
Heart disease and obesity
Metabolic disease and musculoskeletal problems
Heart disease and aerobic performance
Heart disease and musculoskeletal problems
Heart disease and musculoskeletal problems:
is correct because the questions directly address signs and symptoms of these two health issues.
The PAR-Q is a self guided questionnaire designed to screen individuals for health issues.
If present, these health issues can then be evaluated by medical practioners before participating in an exercise program occurs.
Lung disease and musculoskeletal problems: is incorrect because there are no questions related to lung disease in the PAR-Q.
Heart disease and obesity: is incorrect because the PAR-Q contains no screening for obesity.
Metabolic disease and musculoskeletal problems: is incorrect because there is no screening for metabolic disease within the PAR-Q.
Heart disease and aerobic performance: is incorrect because aerobic performance would require an assessment not a screeing.
Which of the following is the highest body mass index that would be considered underweight?
- 3
- 2
- 4
- 6
- 8
17.4:
is correct because underweight is considered any BMI that less than 18.5.
Body mass index allows for a height and weight comparison with a single number.
It can be useful to give an overview of body composition, but may warrant further investigation to give an accurate body composition measurement.
- 6: is incorrect because this BMI would be in the normal range.
- 2: is incorrect because, although in the underweight classification, it is not the highest number.
- 3: is incorrect because, although in the underweight classification, it is not the highest number.
- 8: is incorrect because this number is in the normal range.
When should a personal trainer recommend an appropriate training package to a new client?
Immediately before the assessment, but after the medical history
After the informed consent is completed and goals verbalized
After the PAR-Q is completed
After the goals are verbalized and assessments completed
At the beginnng of the initial client consultation
After the goals are verbalized and assessments completed:
is correct because it is at this point that an action plan can be established.
The appointment frequency and number of sessions purchased should be determined by the client’s needs and goals.
The personal trainer should be clear with the client at the beginning and recommend the exercise program that the client needs to succeed.
After the informed consent is completed and goals verbalized: is incorrect because the action plan is not clear at this point.
After the PAR-Q is completed: is incorrect because not all the information needed to make a recommendation is available at this point.
At the beginnng of the initial client consultation: is incorrect because no information has been gathered.
Immediately before the assessment, but after the medical history: is incorrect because no plan can be formulated at this point.
Which of the following resistance training systems would allow for the highest number of exercises to be performed within a given amount of time?
Circuit training
Horizontal loading
Supersets
Drop-sets
Multiple-sets
Circuit training:
is correct because it involves a series of exercises, performed one after the other minimal rest, and is considered to have a high density of both work and number of exercises.
There are numerous training systems available for resisitance exercise programs whose structures can provide a variety of effects.
Supersets: is incorrect because the density of exercises is not as high.
Multiple-sets: is incorrect because it has a lower exercise density.
Drop-sets: is incorrect because this typically only includes one exercise.
Horizontal loading: is incorrect because this typically only includes one exercise.
Which of the following exercises is performed with a supinated grip?
Triceps extension
Back squat
Dumbbell front lunge
Bench press
Dumbbell biceps curl
Dumbbell biceps curl:
is correct because the palms facing forward such as in the anatomical position, which is the characteristics of the supinated grip, or underhand grip.
Other examples of exercise that use a supinated grip include chin-ups and barbell bent-over rows.
Bench press: is incorrect because this exercise uses a pronated grip.
Triceps extension: is incorrect because this exercise uses a pronated grip.
Dumbbell front lunge: is incorrect because this exercise uses a pronated grip.
Back squat: is incorrect because this exercise uses a pronated grip.
What is the primary goal of resistance training with an unstable surface?
To increase functionality
To strengthen the stabilizing muscles
To overcome bodyweight
To train a specific movement
To strengthen the prime movers
To strengthen the stabilizing muscles:
is correct because these are challenged to a greater extent when an exercise is performed on an unstable surface.
A secondary goal would be to strengthen the prime movers.
Unstable surface training falls under the category of motoin-specific or functional training.
To strengthen the prime movers: is incorrect because this is a secondary goal.
To increase functionality: is incorrect because this is a vague goal that cannot be quantified.
To train a specific movement: is incorrect because very few real world movements occur on an unstable surface.
To overcome bodyweight: is incorrect because unstable surface training can include bodyweight or external resistance.
