초록

Purpose: This study aimed to identify the effect of sling-applied plank exercise on the frequency, stiffness, and decrement ofthe rectus abdominis and longissimus muscles of the trunk according to the stability of the base of support.
Methods: Thirty-three young adults volunteered to participate and were randomly assigned to one of three groups (SS, stablesupport; LES, lower extremity support; and ULES, upper and lower extremity support) according to the stability of the base ofsupport. The muscular properties of the rectus abdominis and longissimus muscles during sling-assisted plank exercise accordingto the stability of the base of support. were measured by using Myoton PRO (Myoton AS, Tallinn, Estonia). Statistical analysiswas performed MANOVA to determine the effect of sling-assisted plank exercise on the muscular properties of the rectusabdominis and longissimus muscles according to the stability of the base of support. Post hoc analysis was conducted usingBonferroni. The level of statistical significance was set at α = 0.05.
Results: When comparing the muscular properties, the muscle frequency and stiffness of the left rectus abdominis of ULESwere significantly decreased compared to that of SS (p < 0.05). In the measurement time, the muscle frequency and the musclestiffness of the right rectus abdominis increased significantly after the intervention (p < 0.05).
Conclusion: It was concluded that the more unstable the base of support (ULES), the higher the exercise strength, and the musclefrequency and stiffness decreased on the rectus abdominis at rest.
