Book excerpt: This clinically and practice oriented, multidisciplinary book is intended to fill the gap between evidence-based knowledge on the benefits of physical activity and exercise during pregnancy and the implementation of exercise programmes and related health promotion measures in pregnant women. It will provide medical, sports, and fitness professionals both with the knowledge needed to allay undue fears regarding the consequences of exercising during pregnancy and with the practical expertise to offer optimal guidance on exercising to pregnant exercisers and athletes. Readers will find up-to-date evidence on the psychological, social, physiological, body composition, musculoskeletal, and biomechanical changes that occur during pregnancy and their implications for physical activity and exercise. Detailed descriptions are provided of the components of exercise testing and prescription for pregnant women, the current evidence-based and practice-oriented guidelines, and exercise selection and adaptation during pregnancy. Exercises specifically targeting musculoskeletal health are discussed separately, and a concluding chapter explains the nutritional requirements in pregnant women who exercise.
