Despite extensive physiological, biochemical, and structural studies, the mechanisms of muscle contraction operating in living muscle fibres are still not clearly understood. This book aims to describe and assess various experimental methods currently used in the field of muscle research. For each method discussed, there is a comprehensive description of its advantages, problems, and limitations. Each chapter also contains a summary of the central results to have been obtained using each method. Comprehensively written by experts in their respective fields, this book will be of interest to all investigators in muscle physiology.
