PURPOSE: There are several methods, such as the abdominal drawing-in maneuver (ADIM), maximal expiration (ME), and Kegel exercise, to strengthen the core muscles. However, to date no study has been conducted to compare the effects of the ADIM, ME, and Kegel exercise on the transverses abdominis (TrA), internal oblique (IO), external oblique (EO), and pelvic floor muscles (PFMs). The purpose of this study was to find out which of the three aforementioned exercises is most effective for contracting the core muscles. METHODS: The thickness of the TrA, IO, EO and PFMs was measured by ultrasonographic imaging during the ADIM, ME and Kegel exercise in 34 healthy participants. RESULTS: There was the significant difference between ADIM and Kegel exercise in the thickness of the TrA (p 0.05). Measurement reliability was assessed using intraclass correlation coefficients (ICC) and the standard error of measurement (SEM). An ICC value of gt;0.77 indicated that reliability measurements was good. CONCLUSION: Kegel exercise was the most effective exercise for the TrA and the PFM, and ME was the most effective exercise for the IO muscles. |
