PURPOSE : This study was conducted to investigate the effect on the dorsiflexion(D/F) angle of the ankle joint when the gastrocnemius and the hamstrings among the superficial posterior line(SBL) muscles were stretched using the Hold-Relax(H-R) technique. Through this, a study was conducted to compare the effects of remote and local interventions using myofascial meridians, especially SBL, and to suggest more effective interventions by comparing the effects of single and multiple interventions. METHOD : In a single-stretch group, the H-R technique was applied to the gastrocnemius and hamstrings, respectively, and in a multiple-stretch group, the H-R technique was applied to both the gastrocnemius and hamstrings. Active range of motion was measured using a universal goniometer. RESULT : As a result of applying the H-R technique to each group, the active D/F angle after the intervention was significantly increased in all groups(p<.001). There was no significant difference in the increase in D/F angle between the group in which the hamstrings was single stretched and the group in which the gastrocnemius was single stretched(p>.05), and when both muscles were stretched at the same time, the effect was significantly higher(p<.05). CONCLUSION : All muscle groups stretched through the H-R technique were effective in in -creasing the angle of D/F. There was no significant difference between the gastrocnemius single-stretch group and the hamstrings single-stretch group, but the two muscle intervention groups showed a higher effect. Therefore, remote intervention according to SBL can be expected to have similar effects to local treatment, it is thought that a holistic treatment approach will be more effective than a single approach.
