Fitness Assessment Flashcards
True or False:
Waist circumference alone can be used as an indicator of obesity related health risk because abdominal obesity is the primary issue; waist circumference may be superior to BMI for this purpose
True
(ACSM)
Mr. Ron, 44 years old, presents to the clinic with a physician’s referral for weight management
and pre-arthroscopic knee surgery strengthening. Mr. Ron is 103.6 kg with a body fat of 30%,
on a 168 cm frame and a weekend athlete. What should the kinesiologist do?
- Tell him to lose some weight before surgery and drop calories by 1,000 per day.
- Explain that weight will be an issue post-surgery and discuss lifestyle modification.
- Suggest that he start a high-intensity plyometric program.
- Focus on a pre-surgery rehabilitation plan for his knee.
- Correct: The kinesiologist is collaborating with the client to identify a need and
solution
Which of the following would be appropriate exercise prescription advice to provide to a client
who has osteoarthritis of the knee joint, pain with weight-bearing activity and atrophy of the
quadriceps muscle?
- Focus on aerobic conditioning.
- Avoid quadriceps strengthening.
- Focus on aquatic exercises.
- Avoid isometric contractions.
- Correct: Water exercises are less weight-bearing than exercises on ground; these
exercises are generally much better tolerated, and clients are able to improve
cardiovascular fitness because physical limitations are usually minimized.
Mr. Charles, 83 years old, performed a 6-minute walk test (MWT) to assess his
cardiorespiratory fitness. He was able to walk for the full 6 minutes. He walked 328 m of the
estimated 409 m, which represents 80% predicted fitness for his age. What intensity range
should be used to prescribe exercise?
- 20-39% HRR
- 60-85% HRR
- 40-59% HRR
- 65-70% HRR
- Correct: This is moderate intensity as outlined by ACSM. Moderate intensity will give
this client an increase in cardiorespiratory fitness.
Mr. Peterson, 38 years old, faints after exercising on the treadmill. He has no history of
fainting. What should the kinesiologist recommend to Mr. Peterson?
- Go to the emergency room.
- Have his blood pressure taken.
- Sit down and rest.
- Continue to exercise
- Correct: Due to loss of consciousness, Mr. Peterson should seek immediate medical
attention.
A kinesiologist has developed a rehabilitation program for Mr. Sanderson after discharge from
a local physiotherapist. Mr. Sanderson has missed 4 consecutive weeks of appointments with
the kinesiologist. How should the kinesiologist proceed upon his return?
- Explain to him that the scheduled time slot will not open up for another 3 weeks.
- Continue with the training plan as if he never missed a session.
- Assess him and make modifications to his treatment plan.
- Suspend the training plan and refer him back to physiotherapist.
- Correct: Reassessment of Mr. Sanderson’s current capacity is required to determine
continuation and modification of program.
Which combination of assessments could be used to estimate a client’s body fat percentage?
- One-rep max and skin fold calipers
- Bioelectrical impedance and dual-energy X-ray absorptiometry
- Dual-energy X-ray energy absorptiometry and Bruce Protocol
- Hydrostatic weighing and goniometer
- Correct: Both measure body composition
When comparing two stress tests at the same workload, before and after 10 weeks of
cardiovascular training, which physiological change would be expected?
- A lower cardiac output
- An increase in oxygen consumption
- An increase in stroke volume
- Higher blood lactate levels
- Correct: Improvements in venous return and blood pressure are a result of short-term
exercise training.
Using the Karoven method, what is the target HR (THR) range of a healthy 60 y/o woman with a RHR of 75bpm who will do moderate aerobic exercise according to ACSM’s FITT guidelines?
Answer: THR= 109-125bpm
ACSM THR guidelines for moderate exercise is 40-59%HRR
HRMax = 220-60= 160 bpm
HRR = HRMax-RHR = 160-75 = 85 bpm
THR= (HRR * %Intensity) +RHR
THR = [(85 * 40%) + 75] to [(85 * 59%) +75] = 109-125bpm
True or False.
A target intensity for health benefits of 135bpm at 63% HRMax is the same bpm as 40% VO2max.
TRUE!
ACSM suggests that certain %VO2max correspond to %HRmax, so you can actually use APHRM to find VO2%
Target intensity for health benefits = 40% VO2 max = 63% HR max
Target intensity for aerobic fitness = 60-80% VO2max = 75-88% HR max
Regression equation
% HR max = 0.64 x % VO2 max + 37
True or False.
A target intensity range for aerobic fitness of 115-135bpm at 75-88% HRMax is the same bpm as 60-80% VO2max.
TRUE!
ACSM suggests that certain %VO2max correspond to %HRmax, so you can actually use APHRM to find VO2%
Target intensity for health benefits = 40% VO2 max = 63% HR max
Target intensity for aerobic fitness = 60-80% VO2max = 75-88% HR max
Calculate the target VO2 at 50% intensity of a person with a VO2max of 32 ml/kg/min.
17.75 ml/kg / min
Target VO2= [(VO2 max -VO2rest) * % intensity desired]+ VO2rest
**VO2rest = 3.5 ml/kg/min
True or False.
The Target VO2 can be calculated using either the VO2max or the VO2 peak.
TRUE.
%VO2 Reserve Method:
%VO2R = [(VO2peak – VO2 rest)* % intensity desired] + VO2 rest
VO2R uses the measured VO2peak
If you measure a 46 year old male’s VO2 max to be 29 ml/kg/min (this indicates below average), and you prescribe them to work at 75-80% VO2max….what is that in METs?
Answer: the person would need to work between 6.2 and 6.6 METs.
lower range = [(29 ml/kg/min) / (3.5 ml/kg/min)] * 0.75 = 6.2 METs
upper range = [(29 ml/kg/min) / (3.5 ml/kg/min)] * 0.8 = 6.6 METs
Someone is told to exercise at a VO2 of 20 ml/kg/min, what is this in METs?
Answer: 5.7 METs
(20 ml/kg/min) / (3.5 ml/kg/min) = 5.7 METs
Find a persons Target METs at 75% intensity if their VO2Max is 29ml/kg/min.
Answer: 6.5 METs
Target METs = (% intensity desired)(VO2max in METs – 1) + 1
= (0.75)(8.29 – 1) + 1
=5.47+1
=6.5 METs
