Lesson 11 - Physiological Assessment quiz Flashcards
During a treadmill test, a client complains of leg cramping but feels that she will be able to finish the test. What is the MOST appropriate course of action?
The Correct Answer is:
Stop the test immediately and possibly refer the client to her primary healthcare professional
Why?
During the administration of any exercise test involving exertion, trainers must always be aware of identifiable signs or symptoms that merit immediate test termination and possible referral to a qualified healthcare professional. These symptoms include:
Onset of angina, chest pain, or angina-like symptomsSignificant drop ( >10 mmHg) in systolic blood pressure (SBP) despite an increase in exercise intensityExcessive rise in blood pressure (BP): SBP >250 mmHg or diastolic blood pressure (DBP) >115 mmHgExcess fatigue, shortness of breath, or wheezing (does not include heavy breathing due to intense exercise)Signs of poor perfusion: lightheadedness, pallor (pale skin), cyanosis (bluish coloration, especially around the mouth), nausea, or cold and clammy skinIncreased nervous system symptoms (e.g., ataxia, dizziness, confusion, syncope)Leg cramping or claudicationSubject requests to stopPhysical or verbal manifestations of severe fatigueFailure of testing equipmentACE Personal Trainer Manual, 5th ed., p. 196
Which of the following is NOT one of three sites used when performing skinfold measurements on a male client?
Abdomen
Chest
Triceps
Thigh
The Correct Answer is:
Triceps
Why?
For men, the three skinfold sites are the chest, thigh, and abdomen. The triceps, thigh, and suprailium are the three skinfold sites for women.
ACE Personal Trainer Manual, 5th ed., p. 199-200
After performing skinfold measurements with a male client, his body-fat percentage is calculated to be 26%. How would you rank this client in terms of body-fat percentage?
The Correct Answer is:
Obese
Why?
In males, a body-fat percentage of 25% or higher is considered obese.
ACE Personal Trainer Manual, 5th ed., p. 205
_______________ provides an objective ratio describing the relationship between body weight and height.
The Correct Answer is:
BMI
Why?
BMI, or body mass index, is an anthropometric measure that provides an objective ratio describing the relationship between body weight and height. The other three options are forms of body-composition assessment.
ACE Personal Trainer Manual, 5th ed., p. 207-208
Which of these assessments measures a client’s muscular endurance?
The Correct Answer is:
Push-up test
Why?
The push-up test measures upper-body endurance, specifically of the pectoralis muscles, triceps, and anterior deltoids. Due to common variations in upper-body strength between men and women, women should be assessed while performing a modified push-up
ACE Personal Trainer Manual, 5th ed., p. 234
What is the waist-to-hip ratio threshold at which a female client’s health is considered at risk?
The Correct Answer is:
> 0.86
Why?
A female client’s health is considered at risk when her WHR is above 0.86. For men, that threshold is above 0.95.
ACE Personal Trainer Manual, 5th ed., p. 210
Measuring VO2max in a laboratory involves the collection and analysis of _______________ during maximal exercise.
The Correct Answer is:
Exhaled air
Why?
VO2max, an excellent measure of cardiorespiratory efficiency, is an estimation of the body’s ability to use oxygen for energy, and is closely related to the functional capacity of the heart. Measuring VO2max in a laboratory involves the collection and analysis of exhaled air during maximal exercise.
ACE Personal Trainer Manual, 5th ed., p. 213
A personal trainer can accurately estimate VO2max from a client’s heart-rate response to exercise.
The Correct Answer is:
TRUE
Why?
Research demonstrates that as workload increases, so do heart rate and oxygen uptake. In fact, heart rate and oxygen uptake exhibit a fairly linear relationship to workload. This relationship allows the personal trainer to accurately estimate VO2max from the heart-rate response to exercise with fairly good accuracy.
ACE Personal Trainer Manual, 5th ed., p. 213
If an activity requires a functional capacity of 6 METs, what is the total oxygen consumption of someone performing that activity?
The Correct Answer is:
21 mL/kg/min
Why?
1 MET is equal to 3.5 mL/kg/min, so 6 METs = 6 x 3.5 mL/kg/min = 21 mL/kg/min
ACE Personal Trainer Manual, 5th ed., p. 215
Which of the following types of physiological assessment is contraindicated for a client with asthma?
Treadmill test
Cycle ergometer test
Ventilatory threshold test
The Correct Answer is:
Ventilatory threshold test
Why?
This type of testing is not recommended for:
Individuals with certain breathing problems [asthma or other chronic obstructive pulmonary disease (COPD)]Individuals prone to panic/anxiety attacks, as the labored breathing may create discomfort or precipitate an attackThose recovering from a recent respiratory infectionACE Personal Trainer Manual, 5th ed., p. 222
The end-point of the VT2 threshold test is determined by the client’s ability to recite the Pledge of Allegiance, or another memorized group of phrases.
The Correct Answer is:
FALSE
Why?
The end-point of the talk test for VT1 (not the VT2 threshold test) is determined by the client’s ability to recite the Pledge of Allegiance, or another memorized group of phrases.
ACE Personal Trainer Manual, 5th ed., p. 222-223
You are performing the YMCA submaximal Step Test on a 40 year old, apparently healthy, female client who you have been working with for the past 4 weeks. After completing the 3-minute assessment you immediately have the client sit down and measure her heart rate for 1 minute. Her post exercise heart rate is recorded as 96 beats per minute. How would you classify this client’s cardiorespiratory endurance?
The Correct Answer is:
Good
Why?
Based on the data presented in Table 8-17, a woman between the ages of 36 and 45 who has a post-exercise heart rate of 96 beats per minute would be classified as having “Good” cardiorespiratory endurance. Lower heart rates following the test correlate with higher cardiorespiratory endurance (for both men and women). Conversely, higher heart rates suggest lower levels of cardiorespiratory endurance.

A male client who weighs 190 pounds has a one-repetition maximum of 225 pounds on the bench press exercise. His relative strength for this exercise is __________.
The Correct Answer is:
1.18
Why?
Relative strength is the maximum force a person is able to exert in relation to his or her body weight and is calculated using the formula: Relative strength = Absolute strength/Body weight, where Absolute strength is defined as the one-repetition maximum. In this case, Relative strength = 225 pounds/190 pounds = 1.18

A competitive soccer player, whose sport requires an ability to accelerate, decelerate, change direction, and then accelerate again, is interested in completing an assessment to serve as a baseline against which he can measure future improvements. Which test will BEST measure these sports skills?
Margaria-Kalamen stair climb
300-yard shuttle run
Pro agility test
40-yard dash
The Correct Answer is:
Pro agility test
Why?
The pro agility test quickly and simply measures an individual’s ability to accelerate, decelerate, change direction, and then accelerate again. In fact, the National Football League and USA Women’s Soccer Team use this assessment as part of their battery of tests.
