Practical Exam Flashcards
What is the formula for BMI?
Body mass divided by height squared
What is classed as a normal BMI
18.5-24.99
A BMI over what, makes you obese?
30+
If there is no obvious narrowing, where do you take the waist circumference measurement from?
Halfway between the 10th rib and the iliac crest
What is stage 1 abdominal strength test?
Pelvic tilt to flatten back to the floor
What is stage 2 abdominal strength test?
Sit-up with the arms relaxed by the side and feet held by assessor
What is stage 3 abdominal strength test?
Sit-up with the arms relaxed by the side without the feet held
What is stage 4 abdominal strength test?
Sit-up with the arms crossed over chest and feet not held
What is stage 5 abdominal strength test?
Sit-up with hands held lightly on the sides of the head and elbows out to the side, feet not held
What is normal blood pressure?
120/80
What is the formula for power (W)?
Cadence x distance x resistance x gravity divided by 60
What does resistance x gravity give you?
Force (newtons)
What does cadence x distance give you?
Displacement (m)
What does force x displacement give you?
Work (Nm)
What is the primary criteria for determining whether VO2max was achieved?
The change in VO2 is less than 2.1ml/kg/min between workload stages
What are the secondary criteria for determining whether VO2max was achieved?
- HRmax during the test is either less than 10bpm or +/- 5% of the theoretical HRmax of the subject
- RER > 1.15
- RPE of > 19
- Blood lactate concentration of >8mmol/L
How do you calculate RER?
VCO2/VO2
How do you calculate predicted HRmax?
208 - (0.7 x age)
What is VO2max?
The maximal amount of oxygen that can be delivered and extracted by the body per unit of time
What is uncorrected VO2max?
A person’s predicted VO2max before it is corrected for their age
What does heart rate reserve represent?
The range between HRrest and HRmax
How do you calculate %maximal heart rate?
HRmax x intensity
How do you calculate heart rate reserve?
HRmax - HRrest
How do you calculate %HRRzone?
HRrest + (HRR x intensity)
What does the astrand-rhyming test predict?
VO2max
What does the PWC170 test predict?
Cardiorespiratory exercise performance
What is absolute PWC170?
The predicted wattage that can individual can work at to obtain a HR of 170bpm
What is relative PWC170?
The predicted wattage per kilogram of body mass the participant will produce at HR of 170bpm
Why do we not go above 170 in the PWC170 test?
Start to lose the linear relationship between HR and power
