Question

Quizplus · Accepted Answer

Exercising at a high altitude where there is less oxygen is most likely to affect slow-twitch fibers, as they rely more heavily on oxygen for energy production compared to fast-twitch fibers. Additionally, high altitude may increase the proportion of slow-twitch fibers in the muscle due to the body's adaptive changes in oxygen delivery and utilization.
