1

Hypertrophy

Increase in size/amount of contractile elements, CSA and strength
Protein degraded when subject to overload -> stimulates pathways that favor protein synthesis

2

Hyperplasia

Increase in number of myocytes
Accounts for

3

Daily Recommended Protein Intake

Sedentary - 0.8g/kg of BW
PA adult - 1g/kg of BW
Endurance - 1.2-1.4 g/kg of BW
Strength - 1.4-1.8 g/kg of BW
Adolescent athlete - 1-2 g/kg of BW
Adult athlete - 2 g/kg of BW

4

Series Elastic Adaptations to Resistance

Translate stretch into force

5

Parallel Elastic Adaptations to Resistance

Stabilize and protect muscle

6

Stretch-shortening Cycle

Creates potential energy that can enhance forces produced by contractile elements

7

Overload

Muscle tension developed at adequate intensity and duration

8

Specificity

Training stresses muscle/fiber/units that need to perform

9

Reversibility

Use it or lose it

10

Individuality

Strength gains variable
Dependent on each individual

11

Immobilization

Type I atrophy fastest
3-4% loss of strength per day
Loss of muscle mass and contractile protein

12

Aging

Loss of approximately 8% per decade
25-30% loss by age 65
Can be slowed, not prevented

13

Aging Loss due to

Fiber atrophy and loss
Motor unit remodeling
