Sources of energy and muscle adaptation in strength training

Adenosine triphosphate (ATP) is the source of energy for all contractile muscles.  Energy is released when ATP breaks down into ADP + P (adenosine diphosphate and phosphorus). Maintaining the availability of energy from ATP for muscle is limited until all stores stored in skeletal muscle are exhausted. ATP reconstitution can be derived anaerobically (anaerobically) or aerobic (aerobic). The basic source of energy will therefore depend…
