Question 1

What muscle adaptations are results of endurance training?

Answer 1

Increase in mitochondria

Increase in capillary density

Question 2

What do fast fibres require?

Answer 2

Higher frequency stimulation

Higher ATP consumption

Question 3

What charachteristics are related to fatigue and shortening velocity?

Answer 3

Acid pre-incubation
Alkaline pre-incubation
SDH; oxidative capacity
Alpha glycerophosphate dehydrogenase

Question 4

What are the potential limitations of hypertrophy?

Answer 4

Increase of pennation angle beyond 45deg reduces force
Tendon tensile strength limits force the tendon can cope with
Size of enthesis limits maximal forces
Size of bones and joints limits maximal forces
Oxygen and metabolite diffusion constraints
Nuclear domain size
