| exercise asthma | <chest medicine> A disease process that is characterised by paradoxical narrowing of the bronchi (lung passageways) making breathing difficult. Treatment includes bronchodilators which are given orally or delivered as an aerosol (inhaled). Corticosteroids are reserved for more difficult cases. Symptoms include wheezing, difficulty breathing (particularly exhaling air) and tightness in the chest. Factors which can exacerbate asthma include rapid changes in temperature or humidity, allergies, upper respiratory infections, exercise, stress or smoke (cigarette). See: status asthmaticus.

| exercise-induced amenorrhoea | The temporary cessation of menstrual function due to strenuous, daily exercise, as in jogging; increased endorphins inhibiting hypothalamic function. (05 Mar 2000) |
| exercise radionuclide angiocardiography | Radionuclide angiocardiography while performing exercise, such as on a treadmill or bicycle. (05 Mar 2000) |
| exercise test | Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate. Physiological data obtained from an exercise test may be used for diagnosis, prognosis, and evaluation of disease severity, and to evaluate therapy. Data may also be used in prescribing exercise by determining a person's exercise capacity. (12 Dec 1998) |
| exercise therapy | Motion of the body or its parts to relieve symptoms or to improve function, leading to physical fitness, but not physical education and training. (12 Dec 1998) |
| exercise tolerance | The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an exercise test. (12 Dec 1998) |
| exercise treadmill | A continuous EKG recording of the heart as the patient performs increasing levels of exercise. The exercise treadmill permits the detection of abnormal heart rhythms (arrhythmias) and provides a screening test for the presence of narrowed arteries to the heart (coronary arteries). Narrowing of these arteries can limit the supply of oxygenated blood to the heart muscle during exercise. (12 Dec 1998) |
