The use of oral contraceptives (OC) is associated with an increased risk of thrombosis, suggesting OC exert procoagulant and/or antifibrinolytic effects. Given that physical exercise physiologically leads to an activation of blood coagulation and fibrinolysis, this study tested the hypothesis that OC might compromise the fibrinolytic response to exercise. Fibrinolytic ...

Crohn's disease (CD) is a chronic inflammatory bowel disease that affects nearly one million people in the United States and Canada. While current pharmaceutical treatments are effective in controlling symptoms, patients continue to experience a reduced quality of life (QOL). Based on preliminary studies, QOL in CD patients may be ...

The insertion (I) variant of the angiotensin-1 converting enzyme (ACE) I/D genetic polymorphism is associated with lower circulating and tissue ACE activity. Some studies have also suggested associations of ACE I/D genotype with endurance phenotypes. This study assessed the relationships between circulating ACE activity, ACE I/D genotype, mechanical efficiency and ...

Lifestyle habits, such as exercise, may significantly influence risk of major vascular thrombotic events. The risk of primary cardiac arrest has been shown to transiently increase during vigorous exercise, whereas regular moderate-intensity exercise is associated with an overall reduced risk of cardiovascular diseases. What are the mechanisms underlying these paradoxical ...

The leisure-time physical activity of 13-year-old Finnish adolescents was assessed in the prospective STRIP study. A self-administered questionnaire (N=565) was used. The leisure-time physical activity index (PAI; MET h/week) was calculated on the basis of reported exercise intensity, duration and frequency (N=558; 53% boys). The participants were divided into Sedentary, ...

It is unclear whether a relationship between physical activity (PA) and maximal oxygen uptake (V'(O2,max)) exists in cystic fibrosis (CF) and, if so, whether the relationship reflects a direct effect or is mediated by the effects of confounding variables, such as pulmonary or muscle function. The objective of the present ...

Although the benefits of increased physical activity and exercise are universally recognized, many older persons remain sedentary, and relatively few achieve recommended levels of activity. Effective interventions to reverse the lack of physical activity in older adults are clearly needed. By understanding correlates of inactivity and appreciating those factors that ...

BACKGROUND: Chronic inflammation has been implicated in the development of cardiovascular disease, diabetes mellitus, cachexia, and osteoporosis. Regular physical activity has been purported to possess "anti-inflammatory" properties which may limit chronic inflammation. Recently, we hypothesized that toll-like receptor 4 (TLR4) may play a role in activity-induced modulation of inflammation. Therefore, ...

It has been proposed that moderate exercise may enhance the immune system. We evaluated whether physical activity at work or at leisure is associated with the risk of pneumonia, and whether the antioxidants vitamin E and beta-carotene affect pneumonia risk in physically active people. A cohort of 16 804 male ...
