Which of the following is FALSE about Slow Twitch Fibers (Slow fibers, slow oxidative fibers) compared with fast twitch:
A.contain more myofibrils
B.contain more myoglobin
C.contain more mitochondria
D.surrounded by more capillaries
E.better for endurance activities
Homework Answers
ANSWER: A. Contain more myofibrils.
Myofibrils content is more in fast twitch muscle fibers than in slow twitch fibers as they are better suited for higher intensity activities.

3. Muscles respond to strength training with hypertrophy. Hypertrophy occurs by a) increasing the number of muscle fibers in the skeletal muscle. b) increasing the diameter of each fiber by adding more myofibrils. c) adding more mitochondria and myoglobin to each fiber. 4. Endurance training (such as training to run a 10k race) aims to increase the % of ATP generated from aerobic respiration during times of intense exercise. Which fiber type is primarily recruited for this type of endurance...
