In fact, whether muscle
fiber type does affect repetition strength may be a moot point, because studies have largely reported no significant fiber type - specific hypertrophy after training with either heavy or light loads (Campos et al. 2002; Mitchell et al. 2012; Schuenke et al. 2012; Morton et al. 2016).
Since muscle
fiber type does not appear to differ substantially between athletes of many groups and untrained controls in many (but not all) cases, it has been suggested that there is a large genetic component to the muscle fiber type displayed by any given individual.

This
does not exclude the possibility that shifts in muscle
fiber type from
type I to
type II could occur through strength training programs of longer durations but the current literature
does not allow us to answer this question (see review by Wilson et al. 2012).
Nevertheless, there
does appear to be a difference in
type IIA and
type IIX muscle
fiber proportion between strength and power athletes and their respective controls, with most studies reporting a greater proportion of
type IIA, and a smaller proportion of
type IIX
fibers in the athletes (Klitgaard et al. 1990; Jürimäe et al. 1996; Fry et al. 2003a; Fry et al. 2003b; Shoepe et al. 2003; Kesidis et al. 2008) but again this is not seen entirely consistently (D'Antona et al. 2006).
But first lets clarify, «all muscle
fibers»
do you mean all
types of
fibers - fast twitch, slow twitch.
As you might imagine, this
type of

In general, the proportion of
type I muscle
fibers does not differ substantially between athletes and controls (Klitgaard et al. 1990; Jürimäe et al 1996; Fry et al. 2003a; Fry et al. 2003b; Shoepe et al. 2003; Kesidis et al. 2008) but this is not seen entirely consistently (D'Antona et al. 2006).

fiber type proportion.

do not concur with the hypothesis that the effect could be due to

This could contribute to velocity - specificity, as muscle
fibers do contract faster in the order
type IIX >
type IIA >

Muscle
fibers of any
type are not all alike; they don't all contract the same; they are not homogenous.
Most studies indicate that strength training programs of standard durations (6 — 12 weeks) in trained subjects
do not lead to a shift between

What it also
does is it actually helps to increase absorption of nutrients and food so when you're eating food and eating nutrients what it actually
does is it actually slows the absorption of the nutrients and of the food and of the value that you need in your food and by
doing these two things by speeding up the removal and slowing down the absorption with the different
types of
fiber it keeps your body running smoothly and healthy because it makes sure that your body get's the nutrition that you need as opposed to having that nutrition become stagnant and not to be absorbed readily and readily available.
