Background and Aim: Obesity is a growing problem in the world due to an imbalance between energy intake and energy expenditure. Evidences show relation between negative energy balance following physical activity and weight loss. The purpose of this study was to examine the acute effect of high intensity dynamic exercise on 24-hour energy intake, macronutrient preferences and appetite indices.
Materials and Methods: Eighty-seven sedentary overweight, 25-40 aged women underwent an acute high intensity exercise session on the treadmill under Bruce protocol. Dietary intake was evaluated by using 24-hour food record, before and after the interval. An appetite questionnaire was filled during 30 minutes before and after the exercise. The data were analyzed by SPSS 17 software. The level of significance for comparing the results of before and after trial was considered at p< 0.05.
Results: Absolute energy intake along 24-hour after interval was significantly decreased (p=0.004). Daily intake of carbohydrate and protein was decreased significantly (respectively p=0.015, p=0.023) after trial. The reverse relation was seen between carbohydrate intake and intensity of exercise (p=0.008). No significant change was found in daily fat intake (p=0.079). Significant changes were found in the tendency of the participants into salty and savory foods (respectively p=0.003, p=0.001). However, appetite behavior in relation to fullness, satiety, hunger, prospective food consumption, and tendency to sweet and fatty foods did not change significantly (p >0.05).
Conclusion: One session of high intensity dynamic exercise could decrease 24-hour calorie intake as well as carbohydrate and protein intake in overweight and obese women.
