a. Striated Muscle Fibers. There are two types of striated muscle fibers-fast (white) and slow (red).
(1) Fast (white). The fast striated muscle fibers can contract rapidly and strongly but only for a short time.
(2) Slow (red). The slow striated muscle fibers tend to contract more slowly but for a sustained duration. The red color of slow striated muscle fibers is because of myoglobin protein. This protein has the capacity to store oxygen within the sarcoplasm. Thus, oxygen is available for the production of energy during the contraction.
