Abstract
PURPOSE: This study aims to examine the effects of trunk flexion on the kinetic characteristics of the lumbar according to the degree of hamstring flexibility. METHODS: This study has as its subjects 29 young adults and divides them into the group (NSRTG, n=15) with the normal length of hamstrings according to SRT and the group (SSRTG, n=14) tending to have shortened hamstrings. Sit and Reach Test was conducted to evaluate the degree of hamstring flexibility. And to examine the kinetic difference of the lumbar at the trunk flexion, it was compared and analyzed by using the picture archiving and communication system (PACS). RESULTS: SSRTG showed more significant difference than NSRTG in the analysis on the trunk flexion of NSRTG and SSRTG. CONCLUSION: According to the analysis, the shortening of hamstrings is the factor that affects the dynamic stability of the lower lumbar through the reduction of the pelvic anterior tilt at the trunk flexion.
