David Swain and Brian Leutholtz take a case-study approach to exercise prescription in this instruction book, giving readers the information needed to prepare for certification by the ACSM. The book covers new topics and incorporates two critical changes to the guidelines. Readers should benefit from detailed information on the adoption of VO2 reserve as the basis for writing exercise prescriptions; data on changes in metabolic equations for determining the oxygen cost of various modes of exercise; and recommendations for prescribing exercise for healthy adults and special cases including children, pregnant women, the elderly, the morbidly obese, and people with heart disease, diabetes, pulmonary disease or peripheral vascular disease.
