I do believe that one runs a risk of overtaining as more training of the fast
twitch fibers takes place.
Not exact matches
Instead, it appears to be related to a much more fundamental metabolic constraint: the length of time required for the animal to reach its theoretical maximum speed, based on the number of «fast
twitch» muscle
fiber cells in the creature's muscles, as compared to the length of time it
takes for those cells to run out of readily available energy.
It doesn't
take much of a signal to recruit slow -
twitch, or endurance muscle
fibers in a motor unit.
The research shows that the changes that occur after weight loss translate to a huge caloric disadvantage of about 250 to 400 calories... Muscle biopsies
taken before, during and after weight loss show that once a person drops weight, their muscle
fibers undergo a transformation, making them more like highly efficient «slow
twitch» muscle
fibers.
But a lot of your Fast B and all your Fast A and Slow
Twitch fibers were not exhausted at rep 10 because they posses more endurance than the strongest of the Fast B
fibers (remember, it has been shown that it can
take several minutes to exhaust all the Fast B
fibers).
I've increased my curl weight to 100 from 80 in about 3 weeks by mixing up on / off days and light / medium with heavy training (trying to
take advantage of the muscle «continuum» and hitting the
fiber on light weight most on one but ending with hitting the fast
twitch for heavy on light medium workouts for at least 1 set of 5 rep)
The process of converting fat to energy is essential for a healthy metabolism, and
takes place in the slow -
twitch muscle
fibers, the aerobic muscle cell's mitochondria.
You get a conversion of your fast explosive — what are called type two muscle
fibers into type one muscle
fibers, which are slow
twitch muscle
fibers that
take a much longer time to fatigue.
Unfortunately for the strength and power fanatics out there, the reverse is not true slow
twitch fibers do not
take on fast -
twitch fibers properties if the strength training volume is high.
It
takes patience, dedication, motivation and the right tips to achieve this feat., and that's considering you have enough natural blend of physical gifts like height, explosive
twitch muscle
fibers, coordination, agility, ability to make instant correct decisions etc..
Since these runners typically have 2 - 3 intense workouts per week that utilize similar energy pathways (which
take priority over strength training), strength training should be scheduled on aerobic recovery days or a long run day, provided the athlete maintain at least one day completely off per week to allow these fast
twitch fibers to recover.
For example, on a set of squats, the trainer
takes a brief rest at the top position as he psyches himself for the next rep.. While doing so effectively reduces the fatigue level during the set, a 2013 study that was published at the 2013 Strength and Conditioning Conference in Las Vegas, revealed that it also reduced the number of fast
twitch fibers that were recruited.
