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. 1. ATP Resynthesis ATP is an energy-rich compound. ATP re...

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 ...

Peak stress developed during the first twitch at each frequency defines the rested-state contraction following a 2 min pause of stimulation. Data were obtained from a representative LV trabecula (length, 2.5 mm; diameter, 238 μm). For this muscle, the order of presentation of ...
THE ENERGY SUPPLY FOR MUSCLE CONTRACTION* I n 1950 A. V. Hill reminded biochemists that "NO certain evidence exists that any of the chemical changes at present known, or believed, to take place as the result of muscular activity, occur otherwise than in recovery . . . . There is... ...
Lactate is an important energy substance [70] that modulates energy production [72], [73] and serves as an energy resource for muscle contraction [74]. In addition, lactate acts as an important signaling molecule [75], [76] for cell repair [77], angiogenesis [78], and inflammation signal...
Muscle energy useCalcium ionsThe majority of energy consumed by contracting muscle can be accounted for by two ATP-dependent processes, cross-bridge cycling and Ca(2+) cycling. The energy for Ca(2+) cycling is necessary for contraction but is an overhead cost, energy that cannot be converted...
