Abstract

Purpose: The purpose of this study was to determine the impact of exercise on appetite and energy intake
in normal and overweight females. Method: Seven normal weight (20<BMI<25), and 7 overweight
(25<BMI<30) inactive women (mean age 23.28 ±1.68) participated in a 6-days semi-experimental study.
First 2 days were assigned as control with no exercise. On the third and fourth days, participants were
asked to run on a treadmill at 60% maximum heart rate reserve for 1 h. Others subsequent 2 days were
consider as post-exercise days with no exercise. Subjects recorded dietary intake using a food diary and
self-weighed intake during each 6 days. Visual analogue scale (VAS) completed at each morning in
fasted state. Results: In normal weight women, average energy intake significantly reduced on postexercise
days (1498.42±336.60 kcal) compare with exercise days (1897.14±342.61 kcal) (p<0.01).
However, in overweight women, relative energy intake significantly reduced in exercise days compare
with control days (p<0.05). There was no significant differences in food compositions across conditions
in both groups and differences in appetite rate were not significant across the days. Interaction effect
between two groups was not significant in all variables.
Conclusion: In conclusions, moderate intensity exercise can create a negative energy balance in
overweight women. This result indicated a favorable clinical implication of exercise on weight control in
overweight women.
