This study tested the effects of inspiratory muscle training on core function compared to a typical core training program. Subjects consisted of 32 healthy, recreationally active individuals (18-25 yrs of age) who were randomly assigned to one of three groups: Control (C), Inspiratory Muscle Training (IMT), and Core Exercise Class (AbEx). IMT performed inspiratory muscle training for 6 wks at 85% maximal inspiratory pressure (MIP), while AbEx performed standard core training of the same duration. Core function was assessed pre- and post-training using a side bridge, prone extension and Stabilizer test of transversus abdominis (TrA) function. MIP was also assessed before and after the treatment. Significant interaction effect was observed for MIP (P≤0.05). IMT MIP increased from 1.06 ± 0.37 to 1.71 ± 0.41 cm H2O (P≤0.05) with no significant pre-post changes in C (1.09 ± 0.29 to 1.15 ± 0.36 cm H2O) or AbEx (0.78 ± 0.31 to 0.88 ± 0.33 cm H2O). A significant interaction effect was noted in prone extension (P≤0.05). Time increased in AbEx from 114.0 ± 53.0 to 154.0 ± 77.6 sec (P≤0.05), with no significant changes in C (158.9 ± 75.5 to 152.1 ± 62.6 sec) or IMT (132.0 ± 39.2 to 132.8 ± 40.3 sec). A significant interaction for the Stabilizer test of TrA function was found (P≤0.05). The IMT group improved from -6.9 ± 12.6 to -10.0 ±11.0 mmHg (P≤0.05), with no significant changes in the Control (-5.0 ± 12.1 to -4.8 ± 13.4 mmHg) or AbEx groups (-15.0 ± 5.8 to -9.7 ± 10.4 mmHg). There were no significant differences (P≥0.05) in the side bridge test. Six weeks of core training and inspiratory muscle training improve core function and target different muscles.
