Exercise Testing for Sports and the Exercise Prescription
Cardiology Clinics, 1987The uses of the exercise test continue to grow and diversify. Familiarity with the mechanics, logistics, and interpretation of these tests leads to their optimal use. The application of exercise testing for competitive or recreational sports, cardiovascular fitness exercise training, and cardiac rehabilitation is the focus of this review.

Cardiology Clinics, 1984
The normal hemodynamic response to dynamic supine exercise embodies the following features: progressive increase in heart rate relative to the work intensity; an increase in cardiac output of 600 ml or greater for every 100-ml increment in oxygen consumption; minimal increase in stroke volume; a progressive increase in oxygen extraction, attaining near-

To the Editor. —The Editorial entitled "Isometric Exercise Testing: Usefulness and Limitations" by Dr Stefadouros, published in the JanuaryArchives(1983;143:26-27), began with a statement that brought me up short: "... Isometric exercise [is] a form of exercise where the contracting muscles develop force without shortening." Can this be so?

Cardiopulmonary Exercise Testing
Clinics in Chest Medicine, 1989Cardiopulmonary exercise testing is an objective method of assessing the functional capacity of a patient. In contrast to clinical assessment and resting investigations, exercise testing is useful in detecting early changes in patients with cardiac or respiratory disease.

Current Opinion in Cardiology, 1991
The number of diagnostic modalities available to the pediatric cardiologist continues to escalate. However, with so many choices, it is often difficult to know what test is most efficacious in a given situation or how often to repeat it. This review summarizes the data from several exercise studies published within the past year.

The phonocardiogram exercise test
IEEE Engineering in Medicine and Biology Magazine, 1999Cardiovascular disease is the leading killer and the major cause of disability in adults. Detection and analysis of heart sounds is an important (and economical) method that can be used to determine the state of the heart and great vessels. In this article we present a newly developed technique for detecting cardiac reserve in both healthy and diseased

Neurology, 1979
The response to a standardized exercise test was investigated in 12 volunteers and 13 patients with aches, cramps, and pains. In men, creatine kinase (CK) levels peaked (up to 1600 mU per milliliter) between 10 and 20 hours after exercise. High levels of blood lactate during exercise were related to the intensity of work and to high levels of CK after ...

Pediatrics, 1981
On the basis of the conclusions of the article "Exercise Performance of Hypertensive Adolescents" by Dov B. Nudel et al (Pediatrics 65:1073, 1980), I would not feel comfortable exercise testing any of my adolescent patients with hypertension. In addition, their study failed to show me any reason to exercise test a hypertensive adolescent.

Cardiology Clinics, 1993
The interpretation of an exercise test should encompass both subjective and objective aspects derived from testing. The patient's appearance, symptoms, and physical examination form an important part of the exercise test as do the hemodynamic responses of blood pressure and heart rate.
