The aim of this study was to investigate the effect of inspiratory muscle training on maximal expiratory pressure (MEP) in healthy sedentary boys. For this purpose, 20 healthy sedentary boys aged 12 years were randomly assigned to two groups as inspiratory muscle training group (IMT, n = 10) and control group (CG, n = 10) who did not perform any training. 30x2 breath exercises were performed as inspiratory muscle training for 4 weeks and 3 days a week for 40% maximal inspiratory pressure (MIP). The MEP test was applied to all subjects 1 day before and after 4 weeks. The data were analyzed in SPSS 22.0 program. The mean of the percentage change with 2x2 mixed factor ANOVA and LSD correction tests were investigated with Mann Whitney U test. As a result of the statistical analysis, a significant difference was found between the IMT pre-and post-test results at the MEP value (p <0.05). In addition, it was observed that IMT showed a significant increase when compared to CG (p <0.05). In conclusion, it can be said that inspiratory muscle training affects the maximal expiratory pressure positively in healthy sedentary boys.
