The effect of different circuit resistance exercise intensities on appetite in men and women

The previous research has identified that many factors can affect appetite. Exercise is one of these factors that affect appetite and subsequent energy intake rate. This study aims to examine the effect of light، moderate and high intensities of circuit resistance exercise on the appetite. 8 healthy men and 8 healthy women participated in this study as subjects voluntarily. Exercise activity with three intensity، light (30 to 40 % of 1RM)، moderate (50 to 60 % 1RM) and high (80 to 90 % 1RM)، and in six moves induding the bench press، armpits، shoulder، leg squat، back foot and leg (each session was 90 minutes) has performed. Appetite were assessed before exercise activity، immediately after، and three and six hours after exercise activity by Visual Analog Scale (VAS). ANOVA with repeated measures and t-test were used to analyze the findings. The significant level was considered (P<0. 05). The Appetite was significantly reduced immediately after the exercise activity than before exercise activity appetite in both men and women. In women desire to food in take 6 hours after light and moderate exercise were decresed up to 33- 35% respectively (P<0. 05)، and feeling of fullness increased 76 and 51 respectively (P<0. 05)، while significant changes in men and in high intensity exercise activity in women and men were not observed. In general، according to the present results، it seems appetite is decreased in low and moderate-intensity resistance training in women، that this appetite decreased can lead to reduced food intake and as a result weight control or loss.
