To investigate the weight loss effect of a comprehensive intervention model combining caloric restriction (CR), physical activity (PA), behavioral therapy (BT), breathing exercise (BE), and functional movement corrective training (FMCT)-referred to as the"CPBBF "model in overweight and obese female college students, so as to provide a reference for scientific weight loss interventions for college students.

From March to May 2022, 46 overweight and obese female college students from Chongqing Water Resources and Electric Engineering College were recruited and randomly divided into an experimental group (24 participants) and a control group (22 participants).The control group received CR (prohibiting ad libitum snacking), PA in the first week, high-intensity interval training (HIIT) for 30 s, and moderate-intensity continuous training (MICT) for 1-5 min alternate 4 sets, duration 15-20 min.From the second week, adjust to HIIT and MICT alternating 3 min each for 5 sets, totaling 30 min, 4 times/week, 70 min/time and BT (60-90 min/session, 3 times/week).The experimental group incorporated FMCT (10-15 min of focused training per session, integrated with PA and daily life) and BE (advocating a gradual transition to proper breathing methods in daily life and low-intensity training, 5 sessions/day, 10 min each).Body oxygen level test (BOLT), Functional Movement Screen (FMS), sports exercise attitude, and body composition indicators were measured at baseline (T0), after 12 weeks of intervention (T1), and after one year of follow-up (T2).The differences were analyzed between groups through generalized estimation equations, and mixed effect model analysis was employed to explore predictive relationships among variables.

The results of the generalized estimation equation showed that time main effects of BOLT values, FMS scores, and exercise attitude among female college students were statistically significant (Wald χ²=18.75, 14.89, 12.45, all P < 0.01);further intragroup comparisons revealed that BOLT, functional motor screening (FMS) scores, and physical exercise attitudeof female college students in the experimental group increased compared to T0, while the control group only showed an increase at T1(all P < 0.05).The group main effects for the aforementioned three indicators were statistically significant (Wald χ²=6.33, 5.21, 4.88), and the time-by-group interactions of BOLT values and FMS scores were also statistically significant (Wald χ²=4.56, 3.97)(all P < 0.05).The time main effects of body weight, body mass index (BMI), and body fat ratio (BFR) in female college students were statistically significant (Wald χ²=44.27, 13.90, 82.33);further intragroup comparisons revealed that the experimental group of female college students showed a decrease in body weight, BMI and BFR at T1 and T2 compared to T0, while the control group only showed a decrease in these indicators at T1(all P < 0.05).The group main effects of weight and BFR were statistically significant (Wald χ²=4.11, 6.46), and the time-by-group interaction of BFR was statistically significant (Wald χ²=8.73)(all P < 0.05).The results of mixed effect model analysis showed that BOLT (β=1.52) and FMS (β=1.81) could both positively predict physical exercise attitude, and physical exercise attitude had statistically significant negative predictive effects on weight, BMI, and BFR (β=-0.08, -0.03, -0.03)(all P < 0.01).

The" CPBBF"comprehensive intervention effectively maintains weight loss effects by modulating the energy compensation mechanism with strong robustness.
