بررسی میزان تغییرات سطوح سرمی لپتین، انسولین، زمینه لیپیدی و نمایه توده‌‌ بدنی پس از یک دوره تمرین تناوبی سرعتی در کودکان چاق

Background: The possibility that childhood obesity is a chronic disease in adulthood becomes enormous. The incidence and spread of obesity has increased substantially over the past two decades. The importance of personal health and quality of life has prompted researchers to study in this field. The aim of this study was to investigate the changes of serum levels of leptin, insulin, lipid profile, and body mass index after a period of sprint interval training in obese children. Methods: In this study, 30 obese children aged 9 to 11 years were randomly targeted placed in two groups (Training and control group). Sprint interval training was conducted for 8 weeks. Before and after training, measurements of leptin, insulin, lipid profile, and body mass index were measured. Data were analyzed using independent t-test (p<0.05). Results: Data analysis showed that after training, leptin, insulin and cholesterol levels were significantly reduced (p=0.001). Also, a significant decrease in BMI was seen (p=0.01). Conclusion: Sprint interval training on leptin, insulin and cholesterol in obese children has a significant impact and this exercise improve body mass index in these individuals.
