correlation between sleep qualiy and muscle strenght among gym students

Between 10 and 40% of adults in Western nations, it is estimated, suffer from insomnia. Muscle loss is more likely to occur when sleep is of poor quality and is brief. As a result, they might also have an impact on muscle strength.
The normative reference value of muscle strength and PSQI scale which is stated in median and range are expressed to be (15.0-60.0) and (1.0-10.0). The relationship between the Muscle Strength and PSQI Scale was quantified by using Spearman correlation coefficient. Muscle strength shows fair negative correlation with the PSQI scale(r=0.142) and p-value(r=0.143).

据估计，西方国家的成年人中约有10%至40%患有失眠症。当睡眠质量低下且睡眠时间短时，肌肉流失的可能性更大，进而可能影响肌肉力量。肌肉力量及睡眠质量指数（PSQI）的规范性参考值以中位数及范围表示，分别为（15.0-60.0）及（1.0-10.0）。通过Spearman相关系数对肌肉力量与PSQI量表之间的关系进行量化，结果显示肌肉力量与PSQI量表呈中等负相关（r=0.142），p值为0.143。
