Abstract：Toinvestigatewhetherphysical exercisecandirectlyafectself-controlandsleepquality，andwhether self-controlfactorsplayamediatingrole intheimpactpathofphysicalexerciseonsleepquality.Inthisstudy，890 femalecollge students in southwest China wererandomlyselectedand investigated byquestionnaires.Theresults showed that physical exercise had a significant effect on body BMI （r=0.055 ），andon thevisual acuityofFemale College Students （r=0.076 ）.The statistical differences in sleep self-regulation control level and sleep quality caused by different levels of exercise among female college students are significant （p=0.000） ），and there were statistically significantcorrelationsamong physical exercise，self-control andsleepquality，physical exercise was positively correlated with self-control （r=0.116） and negatively correlated with sleep quality （R=-0.038 ）.Therewasanegative correlation between self-control and Sleep Quality R=-0.365 ）Exercise positively predicted self-control （β=0.14，p< 0.01），and negatively predicted sleep quality（The lower the score，the higher the quality） β=-0.02 ， p<0.01 ）： Self-control negatively predicted sleep quality （β=-0.41，p<0.01） .Physical exercise can directly and positively affect sleepquality，orindirectlythrough themediating effectofself-control.Theresearchresults indicatethatactiveand moderateintensityphysical exercisecan indirectly improve students'sleepquality through theself-control system，as well as effectively improve students' sleep quality directly.
