Skeletal muscle is one of the three major muscle tissues found in humans. It is made up of thousands of muscle fibers encased by connective tissue sheaths. It is present throughout the body and responds to stimuli by contracting. It serves many functions including maintenance of body position and posture, joint stabilization, storage of nutrients, production of movement and regulation of body temperature. Insufficient dietary protein can cause muscle damage through a variety of mechanisms. Furthermore, intense training can lead to skeletal muscle breakdown which can be worsened by a lack of protein in the diet. Insufficient hydration can reduce blood flow to working muscles that makes them more vulnerable to injury. This book explores all the important aspects of skeletal muscle physiology in the present day scenario. It also provides significant information to help develop a good understanding of the role of nutrition. Those in search of information to further their knowledge will be greatly assisted by this book.
