This research in the August 2013 edition of Clinical Autonomic Research addresses ‘Autonomic changes in young smokers: acute effects of inspiratory exercise’.
One major consequence of smoking is the development of cardiovascular diseases or CVD. These are all the diseases of the heart and circulation. CVD includes coronary heart disease, stroke, peripheral arterial disease and aortic disease. Smoking is one of the risk factors for CVD. The reason for this is because the toxins in tobacco can damage and narrow the coronary arteries. Consequently, this makes young smokers more vulnerable to coronary heart disease.
Purpose of research
Little was known about the early consequences of smoking and the acute effects of a single inspiratory muscle exercise session (IME). This research set out to evaluate the acute effects of inspiratory muscle exercise on cardiac parameters of young smokers.
Evaluation of young smokers
After the acute inspiratory muscle exercise session, researchers evaluate blood pressure and lactate. Furthermore, they record respiratory rate (RR) interval for posterior analysis of heart rate variability, before and after inspiratory muscle exercise.
Findings indicate that a single session of inspiratory muscle exercise is able to reduce systolic blood pressure. Additionally, it improves parasympathetic and sympathetic modulations in young smokers.
“The results of this study highlight the importance of furthering research on this area to better elucidate the acute and chronic effects of inspiratory muscle training on early cardiovascular and pulmonary changes of cigarette smoking.”
