TYPES OF SKELETAL MUSCLE FIBERS

Question 1

SLOW OXIDATIVE FIBERS

Answer 1

-smallest fibers with LARGE amounts of myglobin
-high ATP, slow contraction, high fatigue, low glycogen storage
-maintain posture and endurance

Question 2

FAST OXIDATIVE FIBERS

Answer 2

-intermediately sized
-fast contraction, intermediate resistance to fatigue
-walking/sprinting
-aerobic

Question 3

FAST GLYCOLYTIC FIBERS

Answer 3

-largest fibers
-low ATP generation, fast contraction, little fatigue resistance
-upper limbs/intense movements
-anaerobic
