chap 15 Flashcards
Name 3 tests used to measure recovery
- resistance training 1 rep max
- inflammation (creatine kinase)
- ergometer test
- circumference
- questionnaire
- sleep study
What could improve recovery?
sleep, growth hormone
if we increase MPS will it increase muscle mass
no you need to have higher MPS than MPB for a few days
Does MPB increase when we exercise and why?
yes because MPB and MPS increase
what is anabolic resistance
lower rate of MPS due to age
not being able to reach same level of MPS even if doing the same thing
what is the role of RAPTOR
facilitates the activation of mTORC1 in response to various stimuli, such as growth factors, nutrients, and cellular energy levels.
role of RAPTOR-mTORC
). By modulating these processes, RAPTOR-mTORC1 signaling controls cell growth, proliferation, and survival, thereby playing a critical role in regulating cellular homeostasis and adaptation to environmental cues.
What is a stable isotope?
Naturally occurring atom
Contain an extra neutron
Stable (Non-Radioactive)
Permit distinction between common/rare stable isotope
The method to measure energy expenditure with doubly labelled water isbased on
the difference between the apparent turnover rates of the hydrogen and oxygen of body water as a function of carbon dioxide production.
stable isotope differ in
mass due to different number of neutron
incorporation of stable isotope into a range of biological compound creates an array of
stable isotope tracer to investigate metabolism
difference of stable isotope infusion pump or by drinking
- drinking take more time to reach the plateau vs injection because it has to be absorbed by GI tract
- injection is more invasive and time limited because the patient need to be in bed vs drinking can be done at home
what GCMS used for
machine the measure atome and determine C13 in the muscle
what to use to measure lean body mass, fat mass or bone density
DXA scan
what to use to measure knee isometric strength
kimCom dynamometer
