Chris lecture Flashcards
Why should you focus on outcomes in the clinic?
- Dx underlying pathology
- objective results
- efficacy of current exercise and PT prescription
- Evidence for future exercise prescription
What are some field measurements?
6MWT MMT Antrhopometrics Metabolic Equation Resting BP/HR Spiromety
What are some research measurements?
- 6MWT O2 consumption
- MMT dynamometry
- DXA/MRI/CT
- Indirect alimotry
- GXT
- Body Plethysmography
Field Vs Advanced clinical tests
Indirect vs. Direct
Subjective vs. objective
Cost effective vs. expensive
Surrogate vs. Gold standard
What does the Dual Energy X-Ray Absorptiometry (DXA)do?
measure lean, fat, and bone tissue mass
What was DXA originally developed for?
to measure areal bone mineral density (aBMD)
Units for Bone mineral Density
g/cm^2
How does DXA calculate weights of each area?
using attenuation coefficient.
pQCT
Peripheral Quantitative Computed Tomography
what does pQCT measure?
it assesses Volumetric BMD
how does pQCT differ from DXA?
measures geometry and microarchitecture
Osteoporosis T score?
> -2.5 SD
post-menopause + >50 y/o
Osteoporosis Z score?
> -2.0 SD
Premenopause
Men <50
Where does lipid overflow?
Visceral liver epicardium pericardium Myocardium Intramuscular Renal Sinus Pancreas
What happens with insulin overflow?
Insulin Resistance, inflammation, and Impaired insulin secretion
What is the effect of resistance training on energy expidenture?
Increases total energy expidentur (TEE)
Direct Calorimetry measures what?
Resting Energy Expidenture (REE)
a subjects heat production via change in water temp in chamber
What is anaerobic threshold?
The highest oxygen uptake attained without sustained increase in blood lactate
When does anaerobic threshold occur?
when O2 required by muscles cannot be totally supported by O2 delivery system.
What feeds the energy demands during anaerobic threshold?
supplemented by Anaerobic glycolysis and lactate production.
Anaerobic threshold is correlated closely with
VO2 threshold.
VCO2>VO2
Subjective vs. objective test example
MMT, 40, plyos
vs. MMT with dynamometry
and isokinetic dynamometry
