Quizplus · Accepted Answer

Muscle fiber types can be changed in response to all of the above options, including activity levels, temperature, and thyroid hormone levels. Regular exercise can induce adaptations in muscle cells, leading to an increase in the number of mitochondria and a shift toward more oxidative muscle fibers. Similarly, changes in environmental temperature can affect the expression of proteins involved in muscle metabolism. Thyroid hormone levels can also affect muscle fiber type by regulating the activity of enzymes involved in energy metabolism.
