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，西方国家有10%至40%的成年人饱受失眠困扰。当睡眠质量低下且时长不足时，更易发生肌肉流失，进而可能对肌肉力量产生不良影响。 以中位数及取值范围呈现的肌肉力量与匹兹堡睡眠质量指数（Pittsburgh Sleep Quality Index，PSQI）量表常模参考值分别为(15.0-60.0)与(1.0-10.0)。本研究采用斯皮尔曼相关系数量化肌肉力量与PSQI量表之间的关联，结果显示肌肉力量与PSQI量表呈中等程度负相关（r=0.142，p值=0.143）。
