보디빌더의 대퇴부 근육 분리도 및 기계적 특성에 대한 근육 분리 촉진 기법(Muscle Separation Palpation)의 효과

초록

Bodybuilders’ thigh separation is a key criterion in competition judging, but no scientific studies have verified the effectiveness of muscle separation palpation (MSP) for enhancing thigh separation in competition settings. This study aims to evaluate the effects of the MSP method on thigh muscle characteristics. The thigh of twelve male bodybuilders aged 20 to 39 years with more than 3 years of competition experience were observed. The thigh circumference, muscle mechanical properties, echo intensity (EI) and muscle thickness (MT) of ultrasound were measured to assess muscle characteristics in rectus femoris (RF), vastus lateralis (VL) and vastus medialis (VM). Furthermore, gray scale level co-occurrence matrix (GLCM) texture features were measured to evaluate muscle separation as muscle conditioning. The pre-test measures were re-taken in the subsequent post-test. Thigh circumference and EI significantly decreased after the intervention (p<.01). Muscle stiffness in the RF and VL significantly decreased (p<.01). The stiffness of muscle mechanical properties, RF and VL were significantly decreased after intervention (p<.01). The energy of GLCM were significantly decreased after intervention (p<.05). The entropy of GLCM were significantly increased after intervention (p<.05). Applying MSP before competition is an effective method for enhancing bodybuilders’ competitive performance.
