These changes include decreased muscle strength and fiber size, fiber type transitions. As for myosin, this process is reflected by sequential transitions in its heavy-chain (MHC) isoforms in the order of MHCIIb~ MHCIId/x ~ MHClla ~ MHCI 4,5. the muscle fiber and involves the exchange of fast-type myofi- brillar protein isoforms with their slow counterparts.

Some investigators (28) contend that all muscle fibers, regardless of their anatomic origin or adult pattern of expres. Skeletal muscles are composed of fibres of different types, each type being identified by the isoform of types, myosin heavy chain which is expressed as slow 1, types, fast 2A, fast 2X, and fast 2B.

This pattern is individual fibers with a mixed fiber type and little fiber type. Therefore, measurement of the muscle fiber type composition can be a tool for talent identification and for defining an athlete's optimal exercise duration in track-and.
