“Sport and smoking are clearly contradictory”, expresses the Club of Sports Cardiologists, which also evokes “a dangerous connection”. For what reasons ? Elements of response on a subject subject to many misconceptions.
No, playing sports outdoors does not clean smoky lungs! Any more than physical activity protects once morest the harmful effects of smoking or compensates for its effects! So that it is “ comfortable, efficient and beneficial for the body, the muscles must receive blood as rich in oxygen as possible », insist sports cardiologists. Gold, ” smoking profoundly disrupts this oxygen supply at all levels ». Illustrations.
On the bronchial level, cigarettes cause irritant and inflammatory effects on the bronchial mucosa, bronchoconstriction and alter the functioning of the pulmonary alveoli, therefore the gas exchange capacity. Blood level? “ Carbon monoxide (CO) produced by tobacco combustion has a major impact on oxygen transport capacity. », Explain the doctors.
Less stamina…
« Since the smoker’s heart rate and blood pressure are already relatively increased at rest in a daily smoker, exercise tolerance and endurance capacity are more limited. », they continue. “ Furthermore, the myocardium, itself subject to this poor oxygenation, is in non-optimal conditions to ensure this flow adaptation. “. Which also means that beyond health, smoking constitutes – unsurprisingly – an obstacle to performance.
And to add another layer: “ in the case of regular, daily smoking, which is the case for the majority of dependent smokers, all these disturbances lead to a significant reduction in VO2 max with a constant and significant alteration of sports performance, particularly endurance. “. If you have any questions, do not hesitate to speak to your doctor.
