Effect of Bicycle Ergometer Training in Cotton Labourers On Lung Function and Quality of Life – An Experimental Study

Abstract Background: Cotton is a natural fiber derived from the processing of cotton plants. Labourers involved in cotton production are at higher risk of inhaling cotton dust, which can lead to both acute and chronic respiratory complications such as constriction of bronchus, tightness of chest, and occupational lung diseases. Engaging in physical activities that involve strengthening the inspiratory muscles and training larger muscle groups is crucial for enhancing pulmonary ventilation, increasing exercise capacity, reducing breathlessness, and improving cardiorespiratory endurance. Aim: To investigate whether bicycle ergometer training is beneficial in cotton labourers to improve lung function and quality of life. Materials and Methods: 132 male cotton laborers, aged between 30 and 55 years, were randomly assigned to two equal groups: Group A (Experimental) and Group B (Control). Group A and B received supervised treatment four times per week for eight weeks, with a follow-up conducted one year later. Pulmonary function tests and the St. George's Respiratory Questionnaire (SGRQ) were utilized to assess the participants at baseline, after 8 weeks, and at the follow-up. Results and Discussion: No significant differences (p>0.05) were observed in the baseline characteristics between the two groups of laborers. However, within each group, statistically significant differences (p<0.05) were noted across all outcome measures. Comparing between groups, the experimental group observed statistically higher significant improvements (p<0.05) in the outcome measures for FVC, FEV1, FEV1/FVC, PEFR, and SGRQ scores. Conclusion: Incorporating bicycle ergometer training into pulmonary rehabilitation programs significantly enhances lung function and quality of life for cotton laborers.
