Brief Summary:
Worldwide, childhood and adolescent obesity has reached epidemic proportions despite major efforts to promote weight reduction. Pediatric obesity commonly presages adult obesity and is associated with the development of weight-related comorbid conditions and increased morbidity.
Regular physical activity is an important modality of obesity management. Despite controversies, poor exercise tolerance has frequently been reported in youth obesity and the cause of this limited exercise tolerance remains unknown. Several factors accompanying obesity may interfere with exercise tolerance in obese populations. Respiratory factors, such as decreased thoracic compliance, increased airway resistance and breathing at low pulmonary volumes are associated with obesity and may impact exercise intolerance in this population. Moreover, even in people with otherwise normal lungs, the normal ventilatory responses to exercise can become constrained in obesity. A thorough understanding of the mechanisms underlying this exercise intolerance remains fundamental in order to favour long term adherence to exercise training. This is especially true in youth populations, in which the management of overweight and obesity must be undertaken as soon as possible, due to the early onset of cardiovascular risk factors.
The main purpose of this study is to determine early-onset cardio-respiratory mortality factors in obese adolescents as well as their relation with exercise intolerance (i.e. dyspnea) when compared with age and gender-paired normal-weight volunteers.
