Effect of Inspiratory Muscle Training (IMT) on Respiratory Muscle Strength

Background: Inspiratory muscle training (IMT) put an extra load on the diaphragm, being an accessory to the inspiratory muscles, to improve their strength. Objective: the objective of this study was to determine the effect of an eight-week inspiratory training program (IMT) on respiratory muscle strength in the second-year male students from the College of Physical Education and Sports Sciences. Methods: The experimental research design consist of pre- and post-tests over a duration of eight weeks. Twenty participants were selected at random and divided into either the experimental group which received IMT training program for inspiratory muscles, or the control group, which maintained with their daily routine. ANCOVA tests were utilized to process interference of post-tests statistically and to decrease effect of pre-test as covariate. Results: The results showed that inspiratory muscles training had a significant impact on respiratory muscle strength. Conclusion: An eight-week of IMT have the positive effect on improving respiratory muscle strength.
