다국어 초록 (Multilingual Abstract)

Purpose: The study aimed to identify the effect of static stretching and self-myofascial release on the muscular frequency,stiffness, and decrement of the single and multi-joint hip flexor.
Methods: Thirty young adults volunteered to participate and were randomly assigned to one of two groups (SS; static stretching,SMFR; self-myofascial release). The properties of the iliopsoas muscle for single joint and rectus femoris for multi-joint of thehip during static stretching and self-myofascial release were measured by Myoton PRO (Myoton AS, Tallinn, Estonia). Statisticalanalysis used an independent t-test to determine the effect of static stretching and self-myofascial release on the muscularfrequency, stiffness, and decrement of the single- and multi-joint hip flexor. The level of statistical significance was set at α=0.05.
Results: The comparison of muscular properties revealed that muscle stiffness and muscle decrement of the rectus femoris inthe SMFR group were significantly lower than those in the SS (p<0.05).
Conclusion: It was concluded that SMFR is more effective in enhancing muscle elongation when applied to multi-jointmuscles (e.g., rectus femoris) compared to single-joint muscles (e.g., iliopsoas).
