And only about 5% of the amount of force that type IIx fibers can generate, Produce about 45% of the amount of force that type IIx can produce far more than type I fibers, and yet they retain a degree of aerobic capacity (though a lesser aerobic capacity than type I fibers), Resistance training has been shown to up regulate the gene expression of type I fibers, Resistance training enlarges type II bers, twice as much as it does type I bers. And a potential concern with using longer TULs is that the there may be a reduction in stimulus to the IIa fibers.
