Chapter 2: Protein Flashcards
Leucine % in: Whey Casein Meat Plant based
Whey 11%
Casein 9.3%
Meat 8%
Plant based 6-8%
Not soluble in water
Casein protein
MOre beneficial for skeletal muscle adaptations
Slow digesting whey protein
_ protein:
Enhances MPS with lower doses of protein consumed (less than 15g)
Increases insulin = greater glycogen replenishment = faster recovery
Decreases body fatness
Best bioavailability
Best digestion rate
Hydrolyzed whey
Transport long chain fatty acids to mitochondria for oxidation
Carnitine
- protein maximally stimulate MPS T a 20 g dose
Rich in choline = cognitive function
Eggs
- protein :
Speeds glycogen replenishment
Enhanced glycogen synthesis in liver and skeletal muscle
Whey protein
_ grams of beef protein maximally stimulates MPS
30 grams
_ protein inhibits MPS via negative mTOR expression
Soy protein
MPS after whey consumption
93%
Whey is filtered
Higher quality protein
Expensive
Doesn’t denature valuable proteins and peptides
Micro-filtration
_ stimulate PS to the same degree as EAAs
BCAAs
Improves sleep and cognitive performance
a-lactalbumin
Antioxidant, antiviral, retention of iron
Lactoferrins
There must be sufficient difference in g/kg/d of protein intake btwn groups to get changes in LBM and strength
Protein spread theory
There must be sufficient change from baseline in protein intake to see changes in LBM and or strength
Protein theory
_ is produced in adequate amounts in adults but is essential in children
Histidine
