Week 3 Protein

Question 1

What does insulin do other than store fat for protein?

Answer 1

Protein synthesis and decrease protein breakdown

Question 2

What’s the benefit of consuming amino acid posttraining

Answer 2

Stimulates protein synthesis rather than protein breakdown

Question 3

Is timing crucial for muscle hypertrophy?

Answer 3

Not really, adequate intake is more important

Question 4

What are the Branched Chained Amino Acids? Why is it significant?

Answer 4

Isoleusine, leusine, Valine. These account for 14-18% of the total amino acids in muscle proteins. They also have insulinotropic properties

Answer 5

Regulates protein metabolism. 1. Promotes protein synthesis 2. Inhibits protein breakdown.

Question 6

how could slow digesting proteins like casein be useful for?

Answer 6

Casein could be useful before sleeping when theres no activity, protein synthesis could be promoted for a prolonged period of time

Question 7

What is a satellite cell?

Question 9

What does studies show is the best interval and dosage to take protein post-training?

Answer 9
