The Impact

In many parts of the world, the prevalence of obesity is increasing at an alarming rate. The association between obesity, multiple comorbidities, and increased mortality is now firmly established in many epidemiological studies. However, the link between obesity and exercise intolerance is less well studied and is the focus of this paper. Although exercise limitation is likely to be multifactorial in obesity, it is widely believed that the respiratory mechanical constraints and the attendant dyspnea are important contributors. In this paper, we examined the evidence that critical ventilatory constraint is a proximate source of exercise limitation in individuals with mild-to-moderate obesity. We first reviewed existing information on exercise performance, including ventilatory and perceptual response patterns, in obese individuals who are otherwise healthy. We then considered the impact of obesity in patients with preexisting respiratory mechanical abnormalities due to chronic obstructive pulmonary disease (COPD), with particular reference to the effect on dyspnea and exercise performance. Our main conclusion, based on the existing and rather sparse literature on the subject, is that abnormalities of dynamic respiratory mechanics are not likely to be the dominant source of dyspnea and exercise intolerance in otherwise healthy individuals or in patients with COPD with mild-to-moderate obesity.

Obstructive Pulmonary Disease

Weight loss is a frequent complication in patients with chronic obstructive pulmonary disease (COPD) and is a determining factor for functional capacity, health status and mortality. Weight loss in COPD is a consequence of an inbalance between increased energy requirements and dietary intake. Both metabolic and mechanical inefficiency may contribute to elevated energy expenditure during physical activity, while systemic inflammation has been associated with hypermetabolism at rest. Disease-specific symptoms and systemic inflammation may impair appetite and dietary intake. Altered intermediary metabolism may cause disproportionate wasting of fat-free mass in some patients. A combination of nutritional support and exercise as an anabolic stimulus appears to be the best approach to obtaining marked functional improvement. Patients responding to this treatment even demonstrated a decreased mortality. The effectiveness of anti-catabolic modulation requires further investigation.
