Objectives: The purpose of this study is to investigate eight pilates exercise effective in thickness of abdominal muscles and to suggest effective pilates exercise. Methods/Statistical Analysis: This study was conducted in a total 21 participants applied the eight pilates exercise and using sonography during pilates exercise. Firstly, at resting position using scanning Transverse Abdominis (TrA), Internal Oblique (IO) and External Oblique (EO) thickness in sonography. After measurement, using sonography scanned thickness of the TrA, IO and EO while maintaining the eight pilates exercise. While maintaining exercise, scanning again done if the body was shaken violently. The starting position of all the exercise insupine position were proceeding at supine abdominal strength. Three times scanning was done to calculate and average per data was analyzed. Two minute resting time was taken between the exercises to prevent muscle fatigue. Findings: We compared the thickness variation of TrA, IO and EO in resting position and the eight pilates exercise shown (p<.05). Results of post-test, TrA showed significant differences in resting position, shoulder bridge, hundred, one leg stretch, double leg stretch, roll up, crisscross, scissors and one leg circle exercise (p<.05). IO was significantly different between resting position and roll up exercise (p<.05), EO; similarly significantly different for shoulder bridge between one leg stretch, crisscross and scissors (p<.05). Comparison of all the results, TrA, IO and EO were all statistically significant different (p<.05). This study using sonography during eight pilates exercise compared to real-time measurement of the change in abdominal muscle thickness. As a result, each exercises different in the thickness of the TrA, IO and EO. Most of the previous paper about pilates exercise and abdominal muscles using pilates exercise program, researchers made measurement through the EMG activity of the abdominal muscles after a long period of time applied to the subjects. Electromyography (EMG) is difficult to estimate and indirectly shown muscle contraction, relaxation because it is non invasive method and the data is forecasts. So we conducted a study using sonography. In addition, the various research program of around one hour and mix pilates exercise it is difficult to know how exercise activated each muscles. Application/Improvements: Purpose of this study is to compare the eight pilates exercise affecting TrA, IO and EO thickness compare analyze. Our findings eight pilates exercise are effective in TrA, roll up is effective in IO and one leg stretch, crisscross, scissors are effective in EO. Therefore, strengthening of the trunk local muscle is effective in roll up. In addition, strengthening of the global muscle high kinetic effect can be obtained in one leg stretch, crisscross and scissors with trunk rotation.
