This book shows readers how muscles work and the value of exercise.
Children's Literature - RevaBeth RussellThe "Inside My Body" series uses a two-page spread for each unit or topic. There are always a lot of color, clear photographs, and illustrations, as well as "science behind the myths" sidebars. No, your muscles do not disappear if you do not use them, they get smaller and weaker, but if they are used they will get bigger and stronger. Muscles are made of many units but they can only pull. That means that there must be a muscle to pull in the opposite direction. While the body has different types of muscles, this book focuses on skeletal muscles. Contained in the pages are great pieces of advice for exercise, practice, coaching, and using the correct clothing and equipment for sports. Muscles may have problems such as cramps, where a muscle contracts when you do not want. I learned that the smallest muscle in the body is about the size of the letter I and it prevents too much vibration of the ear bones. Because muscles use a lot of energy, they need fuel from the food you eat. Reviewer: RevaBeth Russell
