ABSTRACT

Background of the study: Vital capacity is a fundamental concept of respiratory physiology, crucial for understanding the mechanics of breathing and the overall health of the respiratory system. Vital capacity represents key measurements that help assess lung function and provide valuable insights into an individual’s respiratory health. Objective of the study is to compare and analyse the effects of Acapella and diaphragmatic breathing exercise in smokers to increase in vital capacity.

Methods: After receiving approval from the Institutions Review Board, this experimental study of a comparative type involving 40 participants was conducted for two months at the Faculty of Physiotherapy department, Dr.MGR. Educational and Research Institute. Upon receiving participation consent, smokers were chosen for the study based on the inclusion and exclusion criteria. They were then divided into two groups using the random sampling technique. Each group had 20 participants, and for an 8-week period, 5 days per week, group A practiced Acapella exercises while group B practiced breathing exercises. Spirometry was used to perform a lung function test before and after the intervention to determine vital capacity.

Result: When comparing the Pretest and Posttest results between Group A and Group B on vital capacity and the FEV1/FVC ratio, it was found that Group A, which engaged in Acapella exercises, improved more than Group B.

Conclusion: This study concludes that compared to diaphragmatic breathing exercises, the Acapella device raised vital capacity in individuals with decreased vital capacity the best. It also improved lung function. Acapella devices can therefore be used as an adjuvant therapy for smokers who have compromised cardiopulmonary functions.
