The former implemented routine health education without any structured exercise intervention, while the latter underwent a 12-week HIIT intervention (three sessions per week, 30 min per session). Comparisons included Body morphology indicators, mental health indicators, biochemical indicators, sleep quality along with quality of life.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Following the intervention, compared to the control group, the study group demonstrated significant improvements across multiple metrics. Specifically, the study group exhibited a lower body mass index, reduced body fat percentage, decreased waist circumference, and a lower waist-to-hip ratio (\n P<\/jats:italic>\n &lt; 0.05). In terms of mental health, the study group had lower scores on the PHQ-9 for depression and the GAD-7 for anxiety, while showing higher scores on the SES for self-esteem (\n P<\/jats:italic>\n &lt; 0.05). Physical fitness improvements were also notable, with the study group displaying higher VO\n 2<\/jats:sub>\n max and vital capacity (\n P<\/jats:italic>\n &lt; 0.05). Additionally, the study group showed better lipid profiles, lower fasting blood glucose levels, and improved sleep quality as indicated by lower PSQI scores (\n P<\/jats:italic>\n &lt; 0.05). Finally, the study group scored higher on all dimensions of the SF-36 quality of life scale (\n P<\/jats:italic>\n &lt; 0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n HIIT intervention can effectively improve body morphology, mental health, physical fitness, biochemical indicators, sleep quality, and quality of life in obese female college students.<\/jats:p>\n
