After about 3 months of adaptation even power lifters can have full power on a ketogenic diet so does this mean the mitochondria have altered to be able to exploit ketones — even in the two fast
twitch fibre types?
Not exact matches
Marathon runners have higher levels of
type I, or «slow
twitch»,
fibres.
«Low repetitions will work on the
type 2 fast
twitch muscle
fibres, which have great power, but fatigue quickly.»
I seem to recall reading that this is true in Tim Noakes book, the Lore of Running - if I recall correctly, he said that only Fast
Twitch A
fibres can be converted to another
type of muscle
fibre, and that Fast
Twitch B
fibres and, more related to the point I'm trying to make, Slow
Twitch fibres, will always remain as their original
type of
fibre.
Fast
twitch muscle
fibres make the gains faster and again raise the overall potential of lean muscle gains; Sure, there are some tall people who are not exactly mesomorphs (there are many mixtures of mesomorph, endomorph and ectomorph genetic
types).
The power clean improves muscle
fibre recruitment and specifically targets the «hard to reach»
type 2B fast
twitch fibres, which are the biggest and strongest muscle
fibres but also the most difficult to enervate.
This can lead to a long - term adaptation of a
fibre type transformation from fast
twitch fibres to intermediate
fibres.
Type II B
fibres are white, while
Type I (slow
twitch) fibers are red.
Type IIb fast -
twitch fibers, or fast glycolytic
fibres (also known as
Type IIx), are recruited for very short - duration high - intensity bursts of power such as maximal and near - maximal lifts and short sprints.
Concerns over bamboo
fibre production are not all that causes a
twitch in the eye of dedicated green
types.
