The first concept to understand in the trifecta is that using resistance

type II muscle
fibers «'' which have a high power output but fatigue fast.
The correct way to involve both
types of muscle
fibers is to «
train till failure».
High - intensity interval

That's not a problem, though, because this
type of

fibers possible.
Interval
training is nothing new, but the Tabata protocol adds new benefits to the mix — it targets the fast - twitch muscle
fibers better than any other
type of
training.
This division of muscle
fibers affects how muscles react to physical
training because every
type has a unique ability to contract and every person has a genetically fixed mixture of these two muscle
types.
This
type of
training recruits as many muscle
fibers as it can, and produces increased secretion of growth - promoting hormones.
Therefore, in order to achieve maximum gains, you need to utilize different rep ranges that will activate both
types of muscle
fibers: use heavy - load, low - rep
training as your primary style but also throw in a couple of sets with lighter loads for more reps.
The results showed a similar hypertrophy of
type I
fibers between the groups after nine weeks of
training, but the group who performed slower on the concentric part had greater increases in
type II
fiber than the group who performed slower on the eccentric part.
This
type of
training demands high strength levels but doesn't require much endurance, which forces to body to use the fast - twitch muscle
fibers.
This
type of
training doesn't require a lot of strength, but it does require endurance and mainly uses the slow - twitch
fibers, but neglects the fast - twitch
type.
This
type of
training causes damage to the muscle
fibers, instead of inducing cell fatigue.
Tabata
training (and HIIT) both share one great advantage for guys looking to hold onto muscle mass: Unlike traditional steady - state cardio, high - intensity intervals help you build and maintain muscle mass because the fast - twitch
fibers — the ones most prone to growth, — are best targeted by this
type of
training.
Type II muscle fibers don't have as much endurance as type I, so if endurance is important to you then you still need to do endurance train
Type II muscle

This system helps the anaerobic

Aiming to improve your physique this information becomes very valuable, it enables to choose the optimum
training (
training types, their balance, the specific range of reps and rest trying to affect different muscle
fibers, unique exercises to work the particular muscle groups etc.) and diet plans (adjusting energy intake, nutrients etc.).
Strength

Although
training may play a role in causing
fiber type shifts, there is likely a large genetic component in the determination of
fiber type (possibly including the ACTN3 R allele).
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).
In Mitchell et al. (2012), the group
training with 30 % of 1RM increased
type I muscle
fiber area by nearly twice as much as
type II muscle
fiber area, while the group
training with 80 % of 1RM increased both
type I and
type II muscle
fiber areas by a similar amount.
However, it is likely that such
fiber type characteristics are not caused by shifts between
type I and
type II muscle
fibers, as aerobic exercise and strength
training produce very similar
fiber type changes (Farup et al. 2014).
Traditionally, it was believed that heavy loads might lead to greater growth of
type II muscle
fibers, while
training to failure with lighter loads might lead to greater hypertrophy of
type I muscle
fibers (Ogborn & Schoenfeld, 2014).
According to this idea, eccentric
training produces earlier recruitment of high threshold motor units, which are suggested to correspond to
type II muscle
fibers (McHugh et al. 2002).
On the other hand, there are some indications that strength
training programs of < 6 months in untrained subjects can lead to a shift within the sub-types of
type II muscle
fibers, from
type IIX to
type IIA muscle
fibers, as measured by muscle
fiber type proportion.
Strength
training in untrained subjects causes a shift in muscle
fiber proportion from
type IIX to
type IIA muscle
fiber type, and may also produce similar effects in
trained individuals.
In addition, the effects of
fiber type after any kind of
training could differ, depending on the time period over which you measure force.
There are indications that eccentric
training could produce even more preferential hypertrophy in
type II muscle
fiber area, compared to concentric
training (Hortobágyi et al. 2000; Friedmann - Bette et al. 2010), but not all studies have reported the same findings (Mayhew et al. 1995; Seger et al. 1998).
Strength
training in untrained subjects can cause an increase in all of the main muscle
fiber type areas (
type I,
type IIA and
type IIX).
Velocity - based
training preserves
type IIX muscle
fiber proportion (Pareja - Blanco et al. 2016), while endurance exercise causes a shift from
type IIX to
type IIA.
When tapering from strength
training, there appears to be a shift back from
type IIA back to IIX
fibers.
Muscle
fiber areas of all muscle
fiber types can increase or decrease following any given
training or detraining intervention.
Strength
training programs of < 6 months (e.g. Häkkinen et al. 2001; Häkkinen et al. 2003) in
trained subjects do not lead to a shift between
type I to
type II muscle
fibers, as measured by muscle
fiber type proportion.
This has led some experts to recommend
training with high bar speeds to maintain
type IIX muscle
fiber area during strength
training.
Given that muscle architecture, muscle
fiber type, and tendon stiffness are poor candidates for velocity - specificity, it is worth reminding ourselves that there must be some changes inherent inside a muscle that contribute to greater gains in force at higher speeds after velocity - focused
training.
In summary, different speeds of
training probably not seem to affect changes in muscle
fiber type, except when comparing between
training to failure or not to failure, when it appears to allow greater retention of
type IIX muscle
fiber area.
This suggests that
type IIX muscle
fibers are the «natural state» before starting resistance
training, and that the move from the very glycolytic
type IIX to the more oxidative
type IIA occurs in response to forceful but also fatiguing contractions (Staron & Johnson, 1993; Douglas et al. 2016a).
Strength
training causes preferential hypertrophy in
type II muscle
fiber area in comparison with
type I muscle
fiber area.
Strength
training causes an increase in
type I,
type IIA, and
type IIX muscle
fiber areas, in both
trained and untrained individuals.
Strength
training likely does not lead to a shift in
type I to
type II muscle
fiber proportion.
Strength
training in untrained subjects increase all of the main muscle
fiber type areas.
This led some experts to recommend focusing on
type II muscle
fiber types in strength
training for hypertrophy, although exactly how this might be achieved is unclear.
Where a muscle tends to display a predominance towards one
type of muscle
fibers, it is unlikely that it will change to display a completely different prevailing
fiber type even after extensive
training.
The changes in specific tension (the ratio of strength - to - size) after strength
training are not explained by changes in muscle
fiber type (Erskine et al. 2011).
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).
In general, a high volume of any
type of mechanical loading (including strength
training or aerobic exercise) produces a shift from
type IIX
fibers to
type IIA
fibers, which may be detrimental for athletes who need to maintain speed.
Strength
training in general produces preferential
type II muscle
fiber growth, compared to
type I muscle
fibers.
