Comparison of Finger-Floor Distance before and after sleep

Abstract

[Purpose] We were used the Finger-Floor Distance (FFD) for an assessment that measures the flexibility of the body in this study. The purpose of the present study was to investigate the difference of the FFD between morning and evening. [Subjects and method] The subjects of this study were 34 college students aged 21 ±2.8 years old. We measured the FFD and sleep time for three days. The FFD was measured ①before bathingintheeveningand②after waking up in the morning. [Results] The FFD value of the morning was significantly higher than that of evening (p<0.05). [Conclusion] We revealed the flexibility of the body decreases after sleep.
