Which weightlifting test best predicts total dynamic strength?
1RM back squat
Partial curl-up
3RM bench press
Verticle jump
1RM bench press
1RM bench press: is correct because research has shown that this is the single best weightlifting test for predicting total dynamic strength. This test measures the strength of the muscles involved in arm extension: triceps, pectoralis major and anterior deltoid. There are many different methods to measure muscular strength.
1RM back strength: is incorrect because this test cannot be performed with every individual.
3RM bench press: is incorrect because it is a multiple repetition test and therefore not as accurate at measuring strength.
Partial curl-up: is incorrect because this is a measure of muscular endurance.
Verticle jump: is incorrect because this is a measure of muscular power.
Obesity can be defined as having a minimum body mass index greater than which number?
20
25
30
40
50
30: is correct because this indicates a body weight that is dangerously high for their height.
Note: BMI is calculated by dividing weight [in kg] by height [in meters] squared. Being obese puts the client at risk for coronary artery disease and other serious health issues.
20: is incorrect because this BMI indicates a normal, healthy body weight.
50: is incorrect because this BMI is much higher than the minimum number to indicate obesity, this BMI indicates an individual that is extremely obese.
40: is incorrect because this BMI is for an individual that is extremely obese.
25: is incorrect because this BMI score indicates that an individual is overweight, but not obese.
Which of the following methods of body composition is least likely to be inaccurate?
Skinfold measurements
Bioelectrical impedance measurements
Durnon-Wormersley calculation
Circumference measurements
Jackson-Pollack calculation
Circumference measurements: is correct because these measurements are inexpensive, easy to record, and have little technician error.
Note: it is the measure of the girth of the body segments that contain both fat and muscle and, thus, doesn’t provide information on the composition of the body segments.
Note: however, these measurements can be used as a source of feedback to evaluate training progress.
Skinfold measurements: is incorrect because these measurements can have a lot of technician error.
Bioelectrical impedance measurements: is incorrect because many conditions must be met by the client to ensure accurate readings.
Jackson-Pollack calculation: is incorrect because this formula uses skinfold numbers which may be inaccurate due to technician error.
Durnon-Wormersley calculation: is incorrect because this formula uses skinfold numbers which may be inaccurate due to technician error.
Which of the following group of assessments would be the most appropriate for a middle-aged, obese client?
Postural assessment, maximum strength test, maximal cardiorespiratory fitness test, blood pressure
Medical clearance from a physician, maximal cardiorespiratory fitness test, blood pressure, muscular endurance assessment
Maximal heart rate, one repetition squat test, body fat composition, blood pressure
None of these
Medical clearance from a physician, resting heart rate, blood pressure, submaximal cardiorespiratory fitness test
Medical clearance from a physician, resting heart rate, blood pressure, submaximal cardiorespiratory fitness test: is correct because obese clients typically have a low fitness level and many health risk factors, which should result in obtaining medical clearance prior to exercise and only performing submaximal tests. The objective of an assessment is to safely determine a client’s initial level of fitness and to glean other objective information that will aid in the program design in order to meet the client’s specific goals.
Maximal heart rate, one repetition squat test, body fat composition, blood pressure: is incorrect because these assessments may be unsafe for this population.
Medical clearance from a physician, maximal cardiorespiratory fitness test, blood pressure, muscular endurance assessment: is incorrect because these assessments may be unsafe for this population.
Postural assessment, maximum strength test, maximal cardiorespiratory fitness test, blood pressure: is incorrect because any group of assessments must include medical clearance.
The measure of the effect carbohydrates has on a person’s blood sugar level is known as which of the following indexes?
Gluten index
Glycogen index
Glycemic index
Lipic index
Amino index
Glycemic index: is correct because this measures glucose levels of the blood before and after consuming food.
Note: the glycemic index has become a useful guide for choosing which foods to eat based on how they will effect blood sugar levels.
Note: this index isn’t a universal guide, however, as people react in different ways to various foods.
Glycogen index: is incorrect because glycogen refers to the stored aspect of carbohydrates, not the blood leve.
Amino index: is incorrect because amino refer to protein.
Gluten index: is incorrect because gluten is only a form of carbohydrate, not every carbohydrate has gluten.
Lipid index: is incorrect because lipids refer to fats.
During the Queen’s College Step Test, what is measured in order to assess cardiorepiratory fitness?
Average heart rate
Duration
Recovery heart rate
Maximum heart rate
Perceived exertion
Recovery heart rate: is correct because the heart rate response to a standard amount of exercise allows for comparison across individuals. In general, the lower the recovery heart rate, or the lower response of the body to the exercise, the more fit the individual.
Note: step tests are not for everyone as those with balance issues may have difficulty and the amount of exertion may be maximal for some.
Maximum heart rate: is incorrect because this may not occur at the end when the heart rate is taken.
Average heart rate: is incorrect because this is not for this particular step test.
Duration: is incorrect because this is a constant value for every individual.
Perceived exertion: is incorrect because this is a subjective, not objective value.
Which of the following is not a sign of cardiovascular, pulmonary or metabolic disease?
Wrist edema
Dizziness
Heart palpitations
Shortness of breath at rest
Jaw pain
Wrist edema: is correct because ankle edema is the known sign or symptom.
When this occurs at night, this is a characteristic sign of heart failure or chronic venous insufficiency.
When a sign or symptom is discovered immediate referral to medical professional is warranted to ensure the safety of the client.
Heart palpitations is incorrect because these forceful or rapid heart beats may be caused by various disorders or cardiac rhythm.
Dizziness: is incorrect because this is a common sign of cardiovascular disease.
Shortness of breath at rest: is incorrect because this a sign of a variety of cardiopulmonary disorders.
Which of the following is not considered a measurement of body composition?
Body mass index
Pulse measurements
Skinfold measurements
Waist-to-hip ratio
Circumference measurements
Pulse measurements: is correct because this measures heart rate. Body composition measurements involves determining how much of the body is fat mass and how much is fat free [muscle, conective tissue, bone and organs].
Note: the benefits of these measurements include identifying a client’s health risks, estimating healthy body weights, assisting in exercise design and evaluation and motivating the client.
Circumference measurements: is incorrect this measures the girth of the body parts giving an indication of body composition.
Waist-to-hip ratio: is incorrect because this measures girth and indicates fat distribution in the stomach area.
Skinfold measurements: is incorrect because this measures adipose tissue that lies directly under the skin and can estimate total fat mass of the bodyy.
How many kilograms does a 175 pound man weigh?
80 kg
17.5 kg
117 kg
378 kg
83 kg
80: is correct because 1 kg equals 2.2 pounds. To calculate kilograms divide the number of pounds by 2.2; kg to lbs multiply the number of kg times the number of pounds.
83 kilograms: is incorrect because this is the number of pounds divided by 2.
378 kilograms: is incorrect because this is the product of the mass in pounds at 2.2.
117 kilograms: is incorrect because this is number pounds divided by 1.5.
17.5 kilograms: is incorrect because this is the number of pounds divided by 10
During the initial consultation, what component may require additional questions for clarification?
Informed consent
Fitness assessment
Medical clearance
All of these
Client goals
Client’s goals: is correct because the personal trainer may require clarification about the specifics of a goal as well as a time line for achievement.
Note: motivational interviewing techniques can be utilized to facilitate intrinsically motivated goals as well as goals that are behavioral istead of outcome related.
Note: furture questions may also be required to clarify the health history.
Informed consent: is incorrect because this document should be straight forward and leave no ambiguity.
Medical clearance form: is incorrect because this document should be provided by a medical physician wth clear language that declares whether the individual is cleared for moderate or high intensity exercise.
Fitness assessment: is incorrect because the test selection should be clear based on medical and exercise history with a medical clearance if needed.
All of these: is incorrect because only the client’s goals should require additional questions.
What is the best coaching method when introducing a new exercise?
Physical demonstration followed by verbal explanation
Verbal explanation only
None of these
Verbal explanation followed by a physical demonstration
Physical demonstration only
Verbal explanation followed by a physical demonstration: is correct because this will give the largest amount of cues for the client to follow. By providing the verbal explanation first, the personal trainer can give the client an overall understanding of the exercise as well as what to look for in the visual demonstration. The ability to demonstrate every assigned exercise is an essential skill for a personal trainer.
Physical demonstration followed by verbal explanation: is incorrect because the client may not know what to look for.
Verbal explanation only: is incorrect because most people are visual learners.
Physical demonstration only: is incorrect because the client has not been cued for what to look for.
None of these: is incorrect because the correct answer is given as an option.
Which of the following types of stretching involves assistance from the personal trainer?
Static stretching
Ballistic stretching
Dynamic stretching
Passive stretching
Active-isolated stretching
Passive stretching: is correct because the client is not actively involved in the stretch during passive stretching. Either the personal trainer, another part of the body, an inanimate object is used to assume the position and hold it.
Note: the goal of passive stretching is to slowly move the client into the stretch in order to prevent forceful action and possible injury.
Static stretching: is incorrect because this can be either active or passive.
Ballistic stretching: is incorrect because this can be either active or passive..
Active-isolated stretching: is incorrect because this type is , by definition active.
Dynamic stretching: is incorrect because it is typically an active stretching method.
Why are most exercises performed with the feet pointed straight ahead?
Prevent injury
Allows for more force production
Is a more stable position
All of these
Allows for greater range of motion
All of these: is correct because body positioning is imperative to proper execution of exercises with strong technique. Placing the feet with the toes pointed straight ahead is the preferred position for most exercises as it aids in placing the knees and hips in the correct position, and, as a result, the rest of the body. Using good positioning, the body can produce more force and move through a greater range of motion while remaining stable and reducing the chance of injury.
If a client was looking to improve their muscular endurance what test should their personal trainer recommend to assess progress?
1.5 mile run
Push-up test
None of these
Skinfold measurements
One rep max bench press
Push-up test: is correct because this is a measure of muscular endurance.
Muscular endurance denotes the ability to produce force repeatedly over time.
The ability is joint and muscle group specific, but the push-up test can give an indication of whole body muscular endurance.
One rep max bench press: is incorrect because this measures muscular strength.
1.5 mile run: is incorrect because this measures aerobic endurance.
Skinfold measurement: is incorrect because this measures body composition.
None of these: is incorrect because the push-up test is a measure of muscular endurance.
Which of the following exercises would be the most appropriate for a client wishing to increase the speed of contraction in the lower body?
Single leg balance reach
Leg extension
Back squat
Jump squat
Medicine ball chest pass
Jump squat: is correct because this exercise can be performed with a high speed of contraction with a moderate amount of tension development. Speed development is achieved by high velocity, low to moderate load exercises.
Back squat: is incorrect because it cannot creat the same speed of contraction as a jump squat.
Medicine ball chest pass: is incorrect because this is an upper body exercise.
Single leg balance: is incorrect because of its low contraction speed.
