These3 sources for ATP production in muscle fibresare explained below. 1. Creatine phosphate This (creatine phosphate reaction) source can typically release enough energy for muscle contraction for up to about15 seconds, e.g. to run for a short time / distance. This process of releasing ATP a...

The direct source of energy for muscle contraction is ATP (Adenosine triphosphate). The total energy in each cell's ATP is only enough for that cell for 1-2 seconds at full intensity. Therefore, ATP needs to be fully recovered.
Immediate Energy Sources in Muscle Contraction The experiments reported in this paper were performed on frog muscles. The energy balance of man has never been made up to now. It is fair to assume that the muscular power of man is obtained from a chemo-mechanical transduction operated... G Ma...
In a study of the question, the thermodynamics of these muscles is discussed and an attempt made to evaluate directly their contraction energy characteristics. The study presumes that the muscle is analogous in some of its properties to both a mechanical spring and an electromagnet. The analogy ...
[73]and serves as an energy resource for muscle contraction[74]. In addition, lactate acts as an important signaling molecule[75],[76]forcell repair[77],angiogenesis[78], and inflammation signal[79]. It is also an important target for cancer therapy[80],[81]. In fact, lactate and its...
Adenosinetriphosphate (ATP) ATP – is made in the mitochondrion ATP is only an immediate source of energy for muscle contraction Muscles have a small supply of ATP which satisfies the body’s initial needs, but is used quickly. Therefore, ATP must be re-synthesized. ATP – is re-synthesized...
ATP is required for all cellular functions. It is used to build the organic molecules that are required for cells and tissues; it provides energy for muscle contraction and for the transmission of electrical signals in the nervous system. When the amount of ATP is available in excess of the ...
Alternative Fuels After depleting ATP stores, muscles turn to other sources: –Creatine phosphate (CP) stores energy, in the form of a bound phosphate molecule, that is used to make ATP –CP stores enough energy for ~ 15 sec. of muscle contractions (~ 70 twitches) ...
3. Electrical stimulation resulted in a marked decline in contraction force and near total depletion of PCr in both fibre types. The ATP turnover rate (P < 0.05) and the magnitude of the decline in ATP (P < 0.05) were greater in type II fibres. Prior to stimulation the muscle glycogen...
