An isolated muscle is believed to be a type 1 fiber. Which of the following should be observed upon stimulation?
A) Slow contraction speed
B) Large fiber diameter
C) Rapid firing frequency
D) Glycolysis metabolism

Question

Quizplus · Accepted Answer

Type 1 fibers are known for their slow contraction speed, as they rely on oxidative metabolism and have a high density of mitochondria. Additionally, they have a small fiber diameter, are able to sustain contractions for longer periods of time, and have a low firing frequency. Glycolysis metabolism is more characteristic of type 2 fibers.
