Q

How does hypertrophy occur?

A
  • overload degrades proteins

- so protein synthesis is stimulated resulting in inc size/amount of contractile elements

Q

How does hyperplasia occur?

A

overload stimulates proliferation of myocytes from satellite cells–little evidence for resistance

Q

What factors drive adaptation?

A

overload, specificity, reversibility, individuality

17
Q

What are effects of immobilization?

A
  • dec protein synthesis=loss mass and contractile units

- type I atrophy fastest=shift to fast fiber type

18
Q

When does muscle mass peak occur?

A

between 25-30yrs

19
Q

High load, low rep training results in:

A
  • inc volume of contractile proteins

- shift from IIB to IIa and I

20
Q

Aerobic training increases the ___ capacity of all fiber types.

A

oxidative
