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).

Some

Trappe et al. (2006) reported that there was a
significant change in muscle
fiber type, involving an 8 % increase in
type I
fibers (48 ± 6 % to 56 ± 6 %) that was created by a loss of hybrids but not by a loss of

There are some indications that strength training with fast bar speeds may cause a shift between
type I and
type IIX muscle
fibers, as shown by the
significant results reported by Liu et al. (2003) and the trends observed by Shepstone et al. (2005) and Pareja ‐ Blanco et al. (2015).

This bring us to one of the main points of MAF Training: to run WITHOUT activating a
significant amount of
Type II
fibers, so that the body learns how to do the majority of the work with
Type I
fibers.
According to Bennett - Ramseur, yogis regularly activate «slow twitch muscle
fibers which improve our endurance but can not generate
significant force, while quick explosive movements found in weight training activate more
type 2 muscle
fibers, which improve our explosiveness, strength, and power, but can not sustain activity for long periods of time.»
In this study as well,
Type 1
fibers grew more when training at 30 % versus 80 % of 1rm (though the difference wasn't statistically
significant).
In case of a
significant interaction, paired - samples t tests were performed to determine training effects within treatment groups or within
types I or II
fibers.
Before intervention, no
significant differences were observed in
type I and
