Skeletal muscle cells can be classified as slow-twitch (type I) or fast-twitch (type II) muscles on the basis of their type of respiration and speed of contraction.
- Adapted for aerobic respirationAand so can continue contracting for long periods.
- Slow contraction speed, limited by rate of oxygen supply.
- No lactate produced, so not susceptible to muscle fatigue.
- Contain many mitochondria and the protein myoglobin, which…
