Objective:
To investigate the effect of a comprehensive exercise intervention program combined with diet control on ANGPTL2 and vascular endothelial function in obese male adolescents, and to provide theoretual basis for exercise to reduce the risk of cardiovascular disease in obese male adolescents.
Methods:
Forty two obese male adolescents and 10 healthy male adolescents were selected, a comprehensive intervention of 6 weeks of exercise combined with diet control was carried out on obese male adolescents, and changes in morphological function, glucose and lipid metabolism, inflammation level and vascular endothelial function were measured before and after the intervention.
Results:
After 6 weeks of comprehensive intervention, the morphological and functional indicators of obese adolescents were significantly reduced:weight, BMI, waist circumference, waist to hip ratio, systolic blood pressure, diastolic blood pressure ( P <0.05); blood lipid levels significantly decreased, including TC, TG and LDL-C ( P <0.05); inflammation levels significantly decreased, including TNF α and ANGPTL2 ( P <0.05); Vascular endothelial function significantly improved:RHI, NO/ET-1, NO, AI( P <0.05). Before and after 6 weeks of comprehensive intervention, the ANGPTL2 of obese adolescents was significantly correlated with weight ( r =0.37), BMI ( r =0.45), RHI ( r =-0.46), NO/ET-1 ( r =-0.41), NO( r =-0.45), and AI ( r =0.33)( P <0.05).
Conclusion
The comprehensive intervention can effectively improve the morphological function, blood lipid level and vascular endothelial function of obese male adolescents, and reduce the circulating level of ANGPTL2. ANGPTL2 may be involved in the process of comprehensive intervention to improve the vascular endothelial function of obese adolescents.

Objective:
To investigate the effects of exercise combined with dietary intervention on glucose and lipid metabolism, liver and kidney function and cardiovascular function in obese adolescents.
Methods:
Seventy-one obese adolescents were enrolled in this study. Six weeks of exercise combined with dietary intervention were performed to determine anthropometry, glucose and lipid metabolism, liver and kidney function and cardiovascular function before and after intervention.
Results:
After 6 weeks of comprehensive intervention, in addition to significant improvement in anthropometry indicators, fasting insulin [(18.76±11.46 vs 11.32±6.54)uU/L], LDL-C [(2.96±0.69 vs 2.22±0.62)mmol/L], TG [(1.57±0.82 vs 0.89±0.37)mmol/L] and TC [(4.52±0.76 vs 3.53±0.62)mmol/L] decreased significantly and insulin resistance improved significantly. AST [(36.1±32.28 vs 22.89±7.27)U/L], ALT [(57.42±61.25 vs 27.86±22.12)U/L], blood urea nitrogen [(4.78±0.89 vs 3.44±0.79)mmol/L] and uric acid [(498.83±120.6 vs 471.07±120.96)mmol/L] were significantly decreased and the detection rates of fatty liver and kidney were significantly decreased(P<0.05), RHI(1.34±0.28 vs 1.69±0.45) and nitric oxide/ endothelin-1 (ET-1) (1.69±0.41 vs 2.67±0.86) significantly increased and atherogenic index (3.06±0.96 vs 2.58±0.80) significantly decreased(P<0.01).
Conclusion
The comprehensive intervention of exercise combined with diet can effectively improve anthropometry indicators, glycolipid metabolism, liver and kidney function as well as cardiovascular function of obese adolescents.
