Jeopardy Questions 1 Flashcards
It is the way to calculate body mass index
Kg / m^2
It is the “more” accurate measure of central fat among all anthropometric measures
Waist circumference
They are two anatomical references to measure a circumference of mid thigh
Inguinal crease and proximal border of patella
They are components of human body.
Fat, water, bone, muscle
If you are ______, the conductance will be lower; thus, bioelectrical impedance will estimate your body fat greater
Dehydrated
It is the name of fat what skinfold measures.
Subcutaneous fat
It is the range of BMI to classify obesity class II.
BMI 35-39.9 kg/m²
It is the degree to which a current is slowed or stopped when an electrical current is applied.
Impedance
They are 3 typical skinfold sites to estimate % body fat for women
Triceps, suprailliac, thigh
It describes when you measure skinfold thickness repeatedly to look for consistency and stability of the measurement.
Reliability
It is the name of the principle that hydrostatic weighing technique is following to assess body composition.
Archimedes principle
It is calculated by
(body weight in the air – weight in the water)
/ density of water
Body volume
It is the technique that follows Poisson’s law to measure body volume.
Air displacement plethysmography
It is the condition that describes when the temperature of air does not remain constant as the volume changes.
Adiabatic condition
It is the formula that you use to calculate body density using hydrostatic weighing method.
Body Density:
Body Weight in Air
[(Wt in Air – Wt in Water)/Density(H2O)] – (RV+ 0.1 L)
They are the components that DXA measures in the body.
Fat, lean body mass, bone
It is considered to be the reference method (gold standard) for body composition assessment
Dual Energy X-ray Absorptiometry (DXA)
DXA scanners pass these two different x-ray energies through the body.
High and low photon energies
If you are 40 years old man with body weight of 220 lbs and height 6 ft, and % body fat determined by DXA is 30%.
What is your current lean body mass?
154 lbs (or 70kg)
If you are 40 years old man with body weight of 220 lbs and height 6 ft, and % body fat determined by DXA is 30%. If you want to reduce body fat to 25%, what is your target weight? (assuming lean body mas does not change)
205.3 lbs (or 93.3kg)
It is the way to measure the amount of air you breathe in and out.
spirometry
It is the maximum volume of air expire after maximum inspiration
Forced vital capacity (FVC)
It is the volume in the lungs after maximum expiration
Residual lung volume (RV)
It is the way to detect airway obstruction.
FEV1.0/FVC less than 70% (or 0.70)
They are the main factors that affect lung volumes. (list 3)
Height, gender, disease, altitude
You and your friend have a bet – whoever has the largest vital capacity receives a pizza from the other person. Your friend’s measured vital capacity is 4.4 L (ATPS). Measurements were made at 27 degree C and 760mmHg. Your measured vital capacity is 4.4 L (ATPS). Measurements were made at 20 degree C and 760mmHg. You are both the same height and weight. Who has the largest vital capacity (BTPS) and receives the free pizza?
Factor for conversion (1.102 at 20 degree C, 1.063 at 27 degree C)
You
