Hormonal Influence on the Adaptability of the Pulmonary System to Exercise in Short Term Smokers

The role of hormones on PFT was well known in the normal course exercise. This study was intended to see the limitations of the pulmonary system in adaptability to exercise in short term smokers. It was observed that exercise per se does not cause a statistically significant change in dynamic lung function parameters MMEF, PEFR, MEF 25% to 75% in either of the groups. This finding supports the hypothesis that the respiratory system is not normally the most limiting factor in the delivery of oxygen even under the predominant influence of stress hormones which is further accentuated by exercise.
