Objective: To explore the effects of cyclic training on metabolic syndrome among obese adolescents, so as to provide a reference for reducing physical burden and maintaining physical health for the obese adolescent population. Methods: The study selected 42 obese adolescents aged 10-17 from Foshan City from June 1 to September 1, 2021. The subjects were randomly divided into a training group (n=24) and a control group (n=18). The training group implemented a 12week training plan (4 times weekly), including two major events and six movements, namely resistance training (push ups, sit ups, forward lunge) and aerobic exercise (high leg lifts, stationary runs,jumping jack), and each action lasted for 25 seconds with a 15 second interval, completing 4 groups. The control group maintained daily living habits.The ttest and Chisquare test were used for statistical analysis. Results: After intervention, the weight, body mass index (BMI), body fat percentage and fat mass of the training group [(72.3±1.8)kg, (26.4±2.0)kg/m2, (31.9±2.3)%, (17.5±2.8)kg] were all lower than before intervention [(73.8±2.1)kg, (30.3±1.8)kg/m2, (34.4±2.5)%, (20.0±3.3)kg], and the muscle mass and physical fitness index of the training group [(32.4±1.1)kg, (67.3±5.3)%] were higher than before intervention [(31.5±1.5)kg, (63.1±6.9)%] (t=-2.75，-7.10，-3.61，-2.83,2.37,2.36, P<0.05). After intervention, the blood glucose, cholesterol, lowdensity lipoprotein cholesterol , waist circumference and hip circumference of the training group [(4.6±0.5)mmol/L, (8.2±0.4)mmol/L, (2.8±1.2)mmol/L, (73.5±4.2)cm, (93.2±5.8)cm] were all lower than those before intervention [(4.9±0.4)mmol/L, (8.7±0.8)mmol/L, (3.9±1.1)mmol/L, (77.8±3.9)cm, (99.5±5.1)cm], and highdensity lipoprotein cholesterol was higher than that before intervention[(3.2±0.3)mmol/L,(2.9±0.8)mmol/L](t=-2.30,-2.74,-3.31,-3.68,-4.00,2.29, P<0.05). There was no statistically significant differences between groups in the parameters of each indicator before intervention (P>0.05), while all indicators in the training group were lower than those in the control group except for muscle mass, physical fitness index and highdensity lipoprotein cholesterol, which were higher than those in the control group after intervention (P<0.05). Conclusions The cyclic training method for 12 weeks is helpful to prevent the metabolic syndrome disease in obese adolescents.It is possible to appropriately increase the intervention methods of cyclic training to reduce the occurrence of metabolic syndrome among obese adolescents.
