Myoglobin fast and slow twitch muscles
WebMuscles are a mixture of two different types of muscle fibre, fast-twitch and slow-twitch, which vary in proportions between muscles. Fast-twitch fibres have a low myoglobin … WebThe reduction in myoglobin results in such muscle fibers appearing less red and paler in color than slow-twitch fibers. The main muscles where fast-twitch fibers are found are those...
