SnapShot: Exercise Metabolism.

Exercise represents a major challenge to whole-body homeostasis. To meet this challenge, myriad acute and adaptive responses take place at multiple cellular and systemic levels. The molecular bases of skeletal muscle adaptations to exercise are mediated by an array of signaling events, pre- and post-transcriptional processes, regulation of translation, and ultimately the increased abundance and/or maximal activity of key proteins with roles in energy provision.
