ハムストリングスに対するスタティック・ストレッチング中のSLR股関節角度変化

抄録

The purpose of this study was to determine the optimal time of stretching to increase flexibility of the hamstring muscles, as defined by measuring the degree of SLR. Nineteen subjects (ten males and nine females), ranging in age from 21 to 25 years, without known musculoskeletal impairments of their spine or lower extremities, participated. A goniometer was used to measure the range of hip flexion with knee extension (the range of SLR) during the 120-second static stretching. The degree of SLR significantly increased (p<0.05) until 75 seconds under sustained hamstring muscle stretching. No significant increase in the degree of SLR occurred during from 75 to 120 seconds. The results of this study suggest that 75-second duration is the effective amount of time to sustain hamstring muscle stretching in order to increase flexibility of the hamstring muscles.
