module 3: adaptations to RT Flashcards
1
Q
What is the difference between anatomical and physiological CSA?
A
- anatomical cuts across the muscle
- PSCA accounts for pennation angle
2
Q
what is the order of importance for factors leading to hypertrophy?
A
- internal factors
- training
- diet
- sleep
- supplements
3
Q
List the structural components of the muscle from largest to smallest
A
- whole muscle
- fascicle
- myofibers
- myofibrils
- myofilaments
4
Q
What are the two ways to measure hypertrophy
A
- radial
- longitudinal
5
Q
what is radial hypertrophy?
A
- sarcomeres in series
- increase in diameter
- thicker muscles
6
Q
what is longitudinal hypertrophy?
A
- increased fascicle length
- maybe sarcomeres in series
7
Q
Does radial hypertrophy increase PCSA or ACSA?
A
it increases both
8
Q
Does longitudinal hypertrophy increase PCSA or ACSA?
A
it only increases ACSA
9
Q
Is sarcoplasmic hypertrophy real?
A
unlikely but there isn’t enough evidence to rule it out
10
Q
Which type of hypertrophy results in more contractile units in a muscle?
A
myofibrillar
