The effect of exercise on leptin, insulin, cortisol and lipid profiles in obese children.
This prospective, randomized study investigated the effect of exercise on leptin, insulin, cortisol and lipid profiles in obese children. A total of 40 obese boys aged 10 - 12 years with a body mass index (BMI) >or= 30 kg/m(2) were randomly separated into an exercise group (n = 20) that underwent a 12-week aerobic exercise programme and a non-exercise (control) group (n = 20). The BMI, low-density lipoprotein, cortisol, leptin and insulin levels were significantly lower in the exercise group after 12 weeks compared with baseline values, whereas high-density lipoprotein levels were significantly higher. In contrast, in the control group, low-density lipoprotein, cortisol and leptin levels were significantly higher after 12 weeks compared with baseline values while high-density lipoprotein levels were significantly lower. These findings indicate the importance of regular exercise in the regulation of body weight and protection against cardiovascular risk factors in obese children.
