Obesity. Hunger. Weight Control ABSTRACT This study investigates the effects of different acute exercise modes on appetite marker ratings. Twelve healthy male subjects participated voluntarily in the study and written informed consent was obtained from all subjects before participation. The subjects underwent four, 120 minute trials (exercise and control) in a randomized crossover design. These included three exercises and one control. In the exercise trials, the subjects performed three different exercise protocols (60 minutes exercise and 60 minutes recovery). In the control trial, subjects rested for 2 hours. The ratings of subjective feelings of appetite markers were reported on 100 mm visual analogue scales (VAS) at baseline and at 20, 40, 60,80, 90, 120 minutes after baseline. The visual analogue scales (VAS) were used to measure the following appetite markers: (i) hunger, (ii) fullness, (iii) desire to eat, and (iv) prospective food consumption. Repeated-measures, and two-factor ANOVA were used to examine differences between the four trials over time to note appetite marker changes. Between-trial differences at each time point were examined using a one-way ANOVA and the Bonferroni post hoc tests when significant interactions were found. The two-way ANOVAs revealed significant (P<0.05) trial x time effects (P<0.05) and time (P<0.05) effects in all appetite markers except hunger. The exercise modes are not different from control (P>0.05) in any of the appetite markers except for the feeling of satiety, and the differences between exercise modes are that, combined exercises decrease the feeling of satiety more than combined exercises, and caused desire to eat and prospective food consumption more than resistance exercises (P<0.05). In conclusion, this finding lends support for a role of exercise in weight management. * Address for correspondence: Dr. Serife Vatansever Assoc.

Overweight and obesity are major risk factors for a number of chronic diseases, including diabetes, cardiovascular dis- eases and cancer (Deighton et al. 2014). Once considered a problem only in high-income coun- tries, overweight and obesity are now dramati- cally on the rise in low- and middle-income coun- tries, particularly in urban settings (Przybylow- icz et al. 2014). Given the current levels of obesity there is a need to better understand processes of appetite control and energy balance. The regulation of appetite and energy intake is influenced by numerous hormonal and neural signals, includ- ing feedback from changes in diet and exercise. The relationship between exercise and appetite regulation has important implications regarding the role of exercise in weight management (King et al. 2015). Exercise can sup- press subjective appetite ratings, subsequent energy intake, and alter appetite-regulating hor- mones for a period of time post-exercise (Howe et al. 2014). Diet and exercise are two lifestyle behaviors that can influence appetite and ener- gy intake, thus, ultimately altering energy balance. Many researchers have studied the effect of exercise on appetite markers. Most of these researches on acute exercises studied the effects of endurance and sprint-interval exercises (Thivel et al. 2012; Deighton et al. 2013; Hago- bian et al. 2013; Williams et al. 2013; Alkahtani et
