The participants who were chosen using a convenience sampling method filled the “Short Form of Young’s Internet Addiction Test” (YIAT-SF), Perceived Freedom in Leisure Scale (PFLS), “Leisure Boredom Scale (LBS), and “Sensation Seeking Scale” (SSS). T-test, MANOVA, ANOVA and correlation analysis were used to analyze the data. T-test results indicated there were no significant differences in the mean scores of “YIAT-SF” with respect to gender (p> 0.05). However, analysis revealed significant differences in the mean scores of “YIAT-SF” with regard to not regularly physical activity participation. There were significant differences in the mean scores of “PFLS” in favor of men participants and regularly physical activity participants (p<0.05). Gender and regularly physical activity participation were significant of "LBS” (p<0.01) in favor of women participants (p<0.05). Similarly, gender were significant of “SSS” (p<0.01) on the all sub-dimensions in favor of men participants (p<0.05). However, there were no significant differences in the mean scores of regularly physical activity participation.
