The acute effects of interval aerobic running and endurance weight training on appetite level in overweight men

The previous research has indicated that many factors can affect on appetite and energy intake rate. Physical activity can be considered as an important one. The aim of this study was to examine the effects of acute interval aerobic running and endurance weight training on appetite in overweight men. In a plan of one group with repeated measures, 12 overweight men (25>BMI>30) voluntarily participated in this study. Participants divided randomly into 3 equal groups including interval aerobic training, endurance weight training, and control groups. Training protocols carried out in 3 weeks with one reating week in order to cleaning of plasma. Interval aerobic training consisted 3 sets, 10 minutes exercises with a 5 minutes interval rest at intensity of 13th Borg scale; and endurance weight training included 8 movements and 20 repetitions at 40 percent of one repetition maximum (1RM). Moreover, the level of appetite was assessed by Visual Analog Scale. The desire to eat was significantly reduced 9 hours after exercise than pre-test in both training groups (p=0.01). The t-test results also showed no significant difference between two type of exercises (p=0.80). Although, the fullness feeling was increased 9 hours after the exercise in both training groups, however, this change was significant only in the endurance weights training group (p=0.001). These values did not significantly change in the control group. In general, according to the present results, the endurance weight training can have a significant effect on desire to eat and also fullness felling 9 hours after exercise than interval aerobic running. The latter had only significant reduction on desire to eat 9 hours after exercise. Therefore, the endurance weight training can be considerd as a good exercise for reducing of appetite level and it can be benefit for overweight men.
