Abstract
Purpose: The aim of this study was to investigate the 24 hour response of appetite and energy intake and the amount of Agouti-Related Protein to the high intensity interval exercise in obese untrained women.
 Methods: Ten obese untrained women were voluntarily selected according to the criteria of the research and evaluated in two experimental and control sessions. Blood samples were collected in two sessions of control and experimental group in five stages. Also, the appetite questionnaire was completed in 9 steps. Also, energy intake was recorded by them during the day.
 Results: Agouti-Related Protein increased significantly in experimental session immediately after exercise compared to the control session (p<0.05). In the Visual analog scale, the feeling of hunger and desire to eat decreased significantly immediately after exercise and before lunch in the experimental session (p<0.05). While feeling of satiety and fullness were significantly higher immediately after exercise and before lunch (p<0.05), in other words, the desire to eat was reduced. Also, exercise significantly reduced energy intake in the experimental session compared to control session (p<0.05). The amount of protein consumption, carbohydrate, and fat decreased in the experimental session compared to the control session, but this decrease was not statistically significant (p>0.05).
 Conclusions: Although a session of high intensity interval exercise resulted in reduced energy intake, but this reduction was not related to just one macronutrient. Hunger and desire to eat decreased after exercise and before lunch but the Agouti-Related Protein increased after exercise.

Material: Ten obese untrained women were voluntarily selected according to the criteria of the research and evaluated in two experimental and control sessions
In another study that investigated the effect of treadmill running on plasma concentration of Agouti Related Protein (AgRP) in rats, the results showed that plasma AgRP levels increased with running [15]
Agouti-related protein Based on Fig 1 plasma levels of AgRP increased significantly in experimental session immediately after exercise compared to control session (p0.05)
Summary
The aim of this study was to investigate the 24 hour response of appetite and energy intake and the amount of Agouti-Related Protein to the high intensity interval exercise in obese untrained women. Since exercise affects eating behavior, and appetite regulation is one of the important issues for weight control in exercise physiology, the purpose of this study was to determine the 24 hour response of appetite and energy intake and the amount of Agouti-Related Protein to the high intensity interval exercise in obese untrained women
