چکیده

Purpose: This study aimed to investigate the effects of eight weeks of regular aerobic exercise combined 
with milk consumption on angiotensin II, ACE and AT1 levels in obese prepubertal boys.
Material and Methods: 28 healthy obese prepubertal boys, 9 to 11 years old, were selected and randomly 
divided into four groups: exercise (Exe), exercise-supplement (Exe-Sup), control (Con) and supplement (Sup). 
Exercise program included three sessions of aerobic exercise (60% - 75% of maximum heart rate). Milk 
consumer groups received 300 ml of low-fat cow milk every day. Blood samples were collected before and 
after the eight weeks. 
Results: After eight weeks, a significant reduction was observed in angiotensin II, AT1, and ACE levels in 
the Exe (p= 0.000, p=0.000, p= 0.000 respectively), Exe-Sup (p= 0.000, p=0.000, p=0.002 respectively) and 
Sup group (p= 0.000, p=0.001, p=0.000 respectively). 
Discussion and Conclusion: The results showed that regular aerobic exercise may decreased angiotensin II, 
AT1 and ACE indices and that, this effect was highly intensified when exercise was combined with milk 
consumption. However, further study is required for more accurate results.
