Test #3 Flashcards
How much times higher than a person’s usual maximal oxygen uptake does the wingate require?
2-4 times higher
How can errors occur with skinfold measurements?
- Technician
- Caliper
- Client
True or False: The more sites you measure, the more accurate your predicted BF% is
False. There isn’t much difference between 3 or 7 site methods
Formula for Power
force x distance / time
What is measured in the Wingate?
Peak Anaerobic Power
Fick Equation Formula?
V02 = CO x (a - VO2 diff)
What are the pros of the BIA?
- Non Invasive
- Portable
- Safe
- Low Cost
- Correlates better with body fat than BMI
For small girths, how many measurements should you take, and how close should they be?
2, and 0.2cm
How does ADP work?
measures volume of air an object displaces inside an enclosed chamber
BIA
Bioelectrical Impedence Analysis
DXA or DEXA
Dual Energy X-Ray Absorptiometry
What are some other anaerobic tests?
- Vertical Jump
- Margaris Step Running Test
- High Velocity Treadmill Running
For large girths, how many measurements should you take, and how close should they be to eachother?
2, and 1cm
Definition: Plethysmography
measurement of size, usually volume
What are SKFs indirectly measuring?
thickness of subcutaneous adipose tissue
True or False: Circumference measurements are preferable to skinfolds. Why or why not?
True. Requires less technician skill.
Chronic adaptations to exercise
↓ HR and BP at rest and any submaximal workload
↑ SV at rest and any submaximal workload
↑ EDV
↑ capillary density
↑ mitochondrial density
↑ total blood volume
↑ lactate threshold (occurs at higher intensity)
improved glucose tolerance and reduction in insulin requirements
Record to the nearest how much for skin calipers?
1mm
Which body parts are considered “small girths”?
- Calf
- Ankle
- Forearm
- Thigh
- Arm
how many skinfolds do you need to do to be good at them
50-100
What was the Wingate Test named after?
A university in Israel
Estimate of skinfolds is accurate to what differential?
+ or - 3.5
What does TBM stand for & consist of?
Total Body Mass
Fatty Mass (FM) & Lean Body Mass (LBM)
Actute Responses to exercise
↑ CO
↑ HR
↑SV
↑EDV (because of the Frank Starling Mechanism)
↑ a-V02 diff
↑ venous return
redistribution of blood flow
FI
Fatigue Index: % of peak power drop off during high intensity, short duration work
Ideal Body Weight formula?
Ideal Body Weight = Present LBM / (100% - desired fat %)
Don’t drink alcohol how many hours before a BIA?
48
What assumption are you making when you take a skinfold measurment?
amount of subcutaneous fat in a particular skinfold is proportional to total amount of overall body fat
Two definitions for V02 max?
- rate of oxygen uptake during maximal aerobic exercise
- largest amount of oxygen an individual can utilize during strenuous exercise to complete exhaustion
What is adipose tissue a matrix of?
connective tissue, blood vessels and cells
