Sentences with phrase «twitch muscle fiber energy»

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.
And molecules that regulate the expression of genes may make athletes more energy efficient, or help create more slow - twitch muscle fibers.
In skeletal muscle, fast - twitch glycolytic fibers use glycogen as the main energy source for anaerobic metabolism, serving to sustain brief periods of high - intensity activity.
They believe that fast twitch muscle fibers are less energy - efficient than the slow twitch ones and burn more energy during workouts.
By supplying fast - twitch muscle fibers with immediate energy, creatine ensures that these fibers don't prematurely fatigue and strengthens their contraction.
Creatine phosphate (creatines high energy molecule form, stored within cells) is used to supply the type 11b muscle fibers (fast - twitch high - glycolytic; the ones that get largest in size) with immediate energy, ensuring these muscles do not prematurely fatigue 6.
Training at this intensity primarily uses slow - twitch muscle fibers, since these fibers provide more most of the mobility for events lasting 2 minutes or longer, workouts at this intensity should comprise most of your training.Training above this intensity will not significantly overload your slow - twitch fibers, which you are attempting to train to become more efficient at using fat and oxygen to produce energy while conserving carbohydrate stores.
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.
It's used in the fast twitch muscle fibers as a source of energy.
In general, Type I, red, slow twitch muscle fibers are aerobic and burn primarily fat for energy.
Fast twitch muscle fibers (which fatigue quickly, but help with quick bursts of energy) convert easily to the better slow twitch muscle fibers that enable endurance exercises.
