The aim of the study that determine effects of yoga practice on pulmonary parameters, respiratory muscle strength, posture, body awareness and quality of life among chronic smokers. Totally 28 volunteers involved to study and they divided into Smokers Group(SG),(n=14) and Control Group(CG),(n=14). The nicotine dependence was determined with Fagerström Test (FT). We assessed pulmonary functions using spirometer, Maximal Inspiratory Pressure(MIP) and Maximal Expiratory Pressure(MEP) using respiratory pressure meter, posture with New York Postural Rating Chart(NYPRC) and Thoracic Spine Range of Motion(TSROM), body awareness using Body Awareness Questionnaire(BAQ) and quality of life with World Health Organisation Quality of Life(WHOQOL-BREF) questionnaire before and after interventions. All the participants did the Yoga exercises twice a week for six weeks of duration. Yoga exercises included active movements and poses while standing(Asana) and voluntary regulated breathing(Pranayama) practice.

The results of the study showed that there is statistical difference in MIP and MIP% values compared to groups(p<0.01) CG have the higher results at the end of intervention. Moreover, spirometry test results, MEP, MIP, NYPRC, BAQ and WHOQOL-BREF scores are statitistically improved after the intervention in both groups (p<0.05). Lastly, SG have the statistically lower scores of improvement on Forced Vital Capacity(FVC)(p>0.05) and nicotine dependence (p=0.001). According to results Yoga practice can improve pulmonary parameters, postural health and quality of life of and also can decrease the dependency on nicotine among smokers.
