Study on the correlation between physical exercise and sleep quality of normal university students
Bibliographic record
Abstract
This study explores the correlation between physical exercise and sleep quality among college students in normal universities, providing reference for improving the level of physical exercise and enhancing sleep quality. The study used a stratified cluster sampling method and surveyed 240 college students from two normal universities in Guangxi using the Physical Activity Readiness Survey (PARS-3) and the Pittsburgh Sleep Quality Index (PSQI) questionnaires. The results show that physical exercise is higher in male students, rural students, and third-year students compared to other types of students within the group (t/F values of 2.03, 6.62, and 6.87, P<0.05). Sleep quality scores are higher in female students and fourth-year students compared to other categories within the group (t/F values of -2.23 and 5.42, P<0.05). The correlation coefficient between physical exercise and sleep quality is r=-0.259 (P<0.01), and the regression model indicates that physical exercise has a significant negative predictive effect on sleep quality (β=-0.25, P<0.01). In conclusion, there are significant differences in physical exercise among college students in normal universities based on gender, hometown, and grade. There are also significant differences in sleep quality among college students in normal universities based on gender and grade. Furthermore, there is a significant negative correlation between physical exercise and sleep quality. It is recommended that schools encourage students to participate in physical exercise to improve their sleep quality and achieve physical and mental health.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
