Eight patients with a diagnosis of atherosclerotic heart disease and a history of typical angina pectoris, uncomplicated by cardiac dilatation or heart failure, were studied by means of standardized, symptom-limited treadmill exercise test. Repeatability of such testing was determined during two control tests 1-1.5 hours apart. From two to six days later, the same patients performed two treadmi...

BACKGROUND Exercise started shortly after breast cancer diagnosis might prevent or diminish fatigue complaints. The Physical Activity during Cancer Treatment (PACT) study was designed to primarily examine the effects of an 18-week exercise intervention, offered in the daily clinical practice setting and starting within 6 weeks after diagnosis, on preventing an increase in fatigue. METHODS Thi...
To examine the electrocardiographic response to exercise in an older population, 280 participants in a longitudinal study of cerebrovascular disease were tested. Subjects were randomly selected from the total 50 to 69-year-old population of Birmingham, Alabama. Approximately 60% of the participants reached a heart rate more than 80% of their predicted maximal heart rate. Subjects were divided i...
Previous studies with 31P nuclear magnetic resonance have demonstrated that patients with chronic congestive heart failure often exhibit increased glycolytic metabolism and impaired oxidative phosphorylation in exercising skeletal muscle, but the mechanism for these changes remains unresolved. This study was conducted to determine whether these abnormalities result from impaired blood flow or o...

Soccer entails intermittent exercise with bouts of short, intense activity punctuating longer periods of low-level, moderate-intensity exercise. High levels of blood lactate may sometimes be observed during a match but the active recovery periods at submaximal exercise levels allow for its removal on a continual basis. While anaerobic efforts are evident in activity with the ball and shadowing ...
background: multiple sclerosis (ms) is a neurological disease with a variety of signs and symptoms. exercise therapy has been shown to improve physical functions in ms. however, questions about an optimal exercise therapy remain. in this regard, we suggest a combined exercise therapy including aerobic and resistance exercises for ms patients. the study is designed to observe, test and compare t...
STUDY OBJECTIVES To determine predictors of oxygen desaturation during submaximal exercise in patients with various lung diseases. DESIGN AND SETTING This retrospective case series used pulmonary function laboratory results from all patients referred to a major tertiary-care center. PATIENTS AND MEASUREMENTS All patients > or = 35 years old who underwent spirometry, diffusing capacity of th...
We investigated the usefulness of the oxygen intake efficiency slope (OIES) as a submaximal measure of cardiorespiratory functional reserve. OIES was derived from the relationship between oxygen consumption (VO2; ml/min) and minute ventilation (VE; l/min) during incremental exercise, which was determined by the following equation: VO2 = a logVE + b, where "a" represents OIES, which shows the ef...
