As complex a topic as exercise testing can be, the authors have maintained a straightforward style of presenting the necessary information. The text is structured around six cardinal chapters, the first of which outlines the purpose of exercise testing. In this chapter, the authors address fundamental exercise physiology, differential diagnosis of disease states, and specific applications of exercise testing, and they include a concise treatment of exercise prescriptions and therapeutic interventions. The focus then shifts to a review of exercise testing equipment and measurement techniques, including tables enumerating the advantages and disadvantages of various modalities of testing. The ancillary respiratory and cardiac equipment needed for each variety of testing is clearly specified for those just embarking on this endeavor. A strong foundation thus having been established, the next chapter explains the various forms of exercise testing, rules on subject preparation, and selection of appropriate testing protocols. Included is a wonderfully precise flow chart diagramming the general sequence of events to be followed in any sort of exercise testing, which I considered a major highlight. Of course, no procedure is devoid of special circumstances, safety precautions, or contraindications, and these are well covered.
