EXERCISE TESTING BASICS
Indications — Incremental aerobic exercise tests are performed in children and adolescents for a variety of reasons (table 1) . The primary indication is to provide the clinician with information about a young patient's physical working capacity. The information gained from an aerobic exercise test is helpful in determining:
●Whether a patient can perform daily activities within his or her functional capacity
●Whether he or she is responding appropriately to an exercise intervention program
●Whether chronic disease progression is affecting the patient's physical capacity
Contraindications — Exercise testing can be performed safely in most children. Absolute contraindications to exercise testing include:
