Which muscle fiber type is beneficial in anaerobic/explosive muscle power activities? Explain

Solution

Answer:

TYPE 2 A FAST TWICTH FIBRE IS BENEFICIAL IN ANAEROBIC /EXPLOSIVE MUSCLE POWER ACTIVITES......FAST oxidative glycolytic, because they use oxygen to help convert glycogen to ATP.

They have ability to rapidly transmit action potentials and generate a cross bridge for quick muscle contraction. These fibre also produce ahigh activity level of myosin ATP ase   and show a rapid rate of calcium release and uptake by the sarcoplasmic reticulum., these properties makes the fibers generate an explosive burst of power for a short period of time. This makes them most suitable to stop and go activities such as basketball, soccer, and hockey, as well as max output activities such as weightlifting, and many track and field events. These fibres using the method of anaerobic glycolosis to produce ATP. These fibers in the middle of the muscle fiber spectrum are th less fatigue resistance, produce more muscular force, and contract at a faster speed ............................
