15
Q

Why is protein metabolism decreases during rt

A

Protein used as fuel
Protein synthesis uses energy
Atp production requires energy

16
Q

Are there sex differences in acute anabolic response

A

Males have higher testosterone but no difference other than that

17
Q

What number of reps causes most protein synthesis and why

A

No specific number just failure and because it requires all fibres

18
Q

What speed increases hypertrophy

A

Faster

19
Q

What is the recommended protein intake

A

Body builder - 1.7g

Endurance - 1.2g

20
Q

When does a plateau for ps occur In terms of dose

A

20g

21
Q

Which protein is most effective for ps

A

Whey

22
Q

What is best pre/post or mor/Eve

A

Pre/post

23
Q

Which dosage gives the most aa availability

A

2x 40g

24
Q

Which dosing strategy causes most ps

A

4x20g

25
Q

Which yields the most positive protein balance mixed aa or essential aa and why

A

Essential aa because although it has a lower synthesis rate it has a much lower break down rate

26
Q

A

Milk

27
Q

A

9

Valine
Isoleucine 
Leucine
Lysine
Methionine
