Habitual aerobic exercise prevents age-related impairments in endothelium-dependent dilation (EDD). We have hypothesized that the pro-inflammatory transcription factor nuclear factor κB (NF-κB) impairs EDD with sedentary aging, and habitual aerobic exercise prevents this age-related suppression of EDD by NF-κB. To test this hypothesis, we have inhibited NF-κB signalling via oral ...

The association between dietary antioxidants and asthma or exercise-induced bronchoconstriction (EIB) is not fully understood. Vitamin C and vitamin E are natural antioxidants that are predominantly present in fruits and vegetables; inadequate vitamin E intake is associated with airway inflammation. It has been postulated that the combination may be more ...

In otherwise healthy adults, moderate aerobic exercise extends lifespan and likely healthspan by 2-6 years. Exercise improves blood sugar regulation, and resistance exercise increases or maintains muscle mass, and is associated with improved cognitive function. On the other hand, evidence for antioxidant supplements increasing longevity in humans is lacking. On ...

Chronic obstructive pulmonary disease (COPD) is a progressive, inflammatory condition, involving airways and lung parenchyma. The disease leads to airflow limitation, and pulmonary hyperinflation, resulting in dyspnea, decreased exercise tolerance, and impaired quality of life. COPD pharmacotherapy guidelines are based on a combination of long-acting beta2-agonists (LABA), long-acting antimuscarinic agents ...
