ABSTRACT

Computer users are at an increased risk of developing musculoskeletal and respiratory dysfunctions due to prolonged sitting and poor postures, such as forward head and rotated neck. These postural issues can lead to reduced energy expenditure and compromised pulmonary functions, often associated with pain due to decreased tissue oxygenation and regional blood flow. Respiratory Muscle Stretch Gymnastics (RMSG) consists of a set of exercises specifically designed to stretch the respiratory muscles and improve lung function. Despite its potential benefits, limited studies have evaluated the effects of RMSG and diaphragmatic breathing (DB) on pulmonary functions. This study aimed to compare the effects of RMSG and DB on Peak Expiratory Flow Rate (PEFR) among computer workers. Sixty participants aged 30–50 years were randomly assigned to two groups. Group A (n = 30) performed RMSG exercises three times per day in four sets, five days a week for two weeks. Group B (n = 30) performed DB exercises for the same duration. PEFR, energy consumption (EC), rate of perceived exertion (RPE), pain, and posture were measured before and after the intervention. Data analysis using SPSS version 22.0 revealed a statistically significant improvement in PEFR in the RMSG group (p < 0.000), while DB showed no significant change.In conclusion, RMSG is a simple, cost-free, and effective intervention that can be self- administered by computer workers to improve PEFR, reduce pain, enhance posture, and increase respiratory efficiency. It can be incorporated as a valuable addition to conventional therapy in sedentary populations.
