Purpose : This study was done to examine the actual effect of the scapular position in these flexibility tests. The purpose of this study was to examine the differences between the measurement of SRT(Sit-and-Reach Test) without intentional abduction of the scapular (pre-test) and with intentional abduction of the scapular (post-test). The hypothesis is: 1. There is no differences in the SRT result of the pre-test and the post-test. 2. There is no differences in the HJA(Hip Joint Angle) result of the pre-test and the post-test. 3. There is no differences in the Spine Motion Test(SMT) result of the pre-test and the post-test. Method : The total 60 people (30 men, 30 women) were participated in this study. In the pre-test, the subjects were asked to sit on the examination table and try the SRT motion: and then the HJA, SRT and the SMT numerical values were taken. In the post-test, the subjects were instructed to intentionally bring the scapula outward from the midline: and the HJA, SRT and the SMT numerical values were taken. Result : In the pre-test, the SRT result averaged 34.17cm, and in the post-test, the SRT result averaged 36.68cm. The difference was about 2.81cm which showed a significant mean statistically (p＜0.01). The measurement increased by 8.22％. The HJA was 85.9˚ in pre-test, and it was 85.5˚ in post-test, giving the 0.4˚ differences. Therefore, it didn´t have a statistical mean (p＞0.05). The SMT value was 69.28cm in the post-test, about 0.28cm decreased. Therefore, it didn´t have a statistical mean(p＞0.05). SRT values and HJA values were correlated (p＜0.01). SMT values and SRT values (p＜0.01), and SMT values and HJA values (p＞0.05) were each in counter correlation. Conclusion : The result of the SRT without intentional scapular abduction (34.17cm) and with intentional scapular abduction (36.68cm) showed a significant increase about 8.22％ (p＜0.01). In SRT, the effect of the intentional scapular abduction on SMT showed no significant means, the pre-test value being 69.59cm and the post-test value being 69.28cm (p＞0.05).
