Effect of inspiratory muscle training Vs resisted thoracic expansion exercise on submaximal endurance in poultry workers

Abstract

Background: Poultry workers display higher rates of asthma and respiratory symptoms than other workers as they are occupationally exposed to many respiratory hazards at work. Dust increases risk of adverse respiratory disease occurrence as it is one of the components present in poultry production. Dust originates from poultry residues, moulds, and feathers and is biologically active as it contains microorganisms. Poultry farm workers are more prone to suffer from respiratory ailments as they are exposed to higher concentration of dust that affects their inspiratory muscle strength to reduce. For this type, rehab can be given to increase their inspiratory muscle strength and therefore increase their endurance. Aim: To compare the effect of inspiratory muscle training and resisted thoracic expansion exercise on submaximal endurance in poultry workers. Objective: effect of thoracic expansion exercises and inspiratory muscle training in poultry workers with 6 minute walk test. Material and methodology: Total number 30 poultry workers between age group of 30-50 years of both genders were selected by convenient sampling. 6 minute walk test outcome measure was taken pre and post intervention. Intervention is based on strengthening of inspiratory muscle 5 times a week for 4 weeks for 15mins. Result: after comparing pre and post intervention data using paired t test showed that there was significant improvement in 6MWT(p<0.0001) and in unpaired t test in 6MWT(p0.0445). Conclusion: Both interventions were effective but inspiratory muscle training was more effective.
