WebWhich of the following statements are true about the influence of muscle fiber type on the force velocity curve? a) At any given velocity of movement, the peak power generated is greater in a muscle that contains a high percentage of fast fibers (i.e., type IIx) compared with a muscle that contains a high percentage of slow fibers (i.e., type I). WebIdentify the primary changes that occur in skeletal muscle fibers in response to resistance training. Fast-to-slow shift in fiber type from type IIx to IIa (5-11% decrease in type IIx fibers with a corresponding increase in type IIa fibers following 20 weeks of training).
