task 6 Flashcards
1
Q
muscle fatigue is primarily caused by..
A
the increasing concentration of metabolic by- products
2
Q
lack of energy leads to
A
the formation of lactic acid -> inhibits muscle function ->muscle fatigue
3
Q
during fatigue the amplitude (intensity) of the contraction (…) and the contraction time (….)
A
decrease, increase
4
Q
which muscle fiber exhaust faster- the white or red?
A
the white muscles
5
Q
what are the characteristics of white muscle fibers
A
glycolytic(anaerobic metabolism) contains fast-twitch fibers, exhaust faster, for eg. m. gastrocnemius
6
Q
what are the characteristics of red muscle fibers
A
oxidative, slow-twitch fibers, exhaust slower, for eg. m. long. dorsi
