ABSTRACT

The present study evaluates the effect of partial sleep restriction on postural control in judokas. Fourteen elite-level judokas performed three static postural control tests (the Unilateral Stance (US, on the Right and Left Foot); the modified Clinical Test for the Sensory Interaction on Balance (mCTSIB, on a firm and an unstable surface) stance with the eyes opened and then closed, and the Weight-Bearing Squat test (WBS)) after (i) a reference-normal-sleep-night (RN) and (ii) 4-h of partial sleep restriction at the end (SREN) (i.e., sleep from 22h30 to 03h00) or the beginning (SRBN) (i.e., sleep from 03:00h to 07:00h) of the night. Concerning US, sway velocity increased significantly after SRBN and SREN, in comparison with RN (p < 0.001) and was significantly higher in closed vs. open eyes during SRBN, SREN and RN (p < 0.001). For mCTSIB, sway velocity increased significantly during SBND and SRBN, compared to RN (p < 0.001) and was higher with eyes open than eyes closed in the foam surface during SRBN, SREN and RN (p < 0.0001). For WBS, there were no significant between conditions differences. In conclusion, partial sleep restriction of 4-h may negatively affect the postural control of judokas.

摘要

本研究评估了部分睡眠限制对柔道运动员姿势控制的影响。14 名精英级柔道运动员进行了三项静态姿势控制测试（单侧站姿（US，左右脚）；改进的平衡感觉交互临床测试（mCTSIB，在坚固和不稳定的表面上）站姿眼睛睁开然后闭上，负重深蹲测试 (WBS)) 在 ( i ) 参考正常睡眠夜 (RN) 和 ( ii ) 之后) 晚上结束 (SREN)（即从 22:30 到 03:00 睡觉）或开始 (SRBN)（即从 03:00 到 07:00 睡觉）的 4 小时部分睡眠限制。关于美国，与 RN 相比，SRBN 和 SREN 后摇摆速度显着增加（p < 0.001），并且在 SRBN、SREN 和 RN 期间闭眼与睁眼时摇摆速度显着提高（p < 0.001）。对于 mCTSIB，与 RN 相比，SBND 和 SRBN 期间摇摆速度显着增加（p < 0.001），并且在 SRBN、SREN 和 RN 期间，在泡沫表面睁眼时摇摆速度高于闭眼时（p <0.0001）。对于 WBS，条件之间没有显着差异。总之，4 小时的部分睡眠限制可能会对柔道的姿势控制产生负面影响。
