Biology of Exercise

Exercise training provokes widespread transformations in the human body requiring coordinated changes in muscle composition blood flow neuronal and hormonal signaling and metabolism. These changes enhance physical performance improve mental health and delay the onset of aging and disease. Understanding the molecular basis of these changes is therefore important for optimizing athletic ability and for developing drugs that elicit therapeutic effects. <p/>Written and edited by experts in the field this collection from <em>Cold Spring Harbor Perspectives in Medicine </em>examines the biological basis of exercise from the molecular to the systemic levels. Contributors discuss how transcriptional regulation cytokine and hormonal signaling glucose metabolism epigenetic modifications microRNA profiles and mitochondrial and ribosomal functions are altered in response to exercise training leading to improved skeletal muscle hippocampal and cardiovascular function. Cross talk among the pathways underlying tissue-specific and systemic responses to exercise is also considered. <p/>The authors also discuss how the understanding of such molecular mechanisms may lead to the development of drugs that mitigate aging and disease. This volume will therefore serve as a vital reference for all involved in the fields of sports science and medicine as well as anyone seeking to understand the molecular mechanisms by which exercise promotes whole-body health.
