The purpose of this study was to determine the effect of different doses of nicotine on psychomotor performance in athletes and non-athletes. Seventy-two male college students (36 athlete, 36 non-athlete; range age=18 to 24) were recruited from Kharazmi university to participate in the study. Their level of physical activity participation determined via a General Information Questionnaire. Each group of 36 male was randomly divided into three subgroups of 12 (4 mg nicotine gum, 2 mg nicotine gum, and 0 mg nicotine gum). In order to ensure the health and no history of drug use, particularly smoking cigarette, a general health screening form was used. This study was an experimental and applied. The data were collected using a choice reaction time (CRT) apparatus and Vienna Two-Hand Coordination (2HAND) test. In addition to descriptive statistics, between groups repeated measures ANOVA was used (α=0.05). The results show that there was no significant differences between choice reaction time means in terms of groups (P=0.353) or type of intervention (P=0.646). Therefore, the effects of different dosages of nicotine on CRT in both athletes and non-athletes was not significant (P=0.0501). There was significant differences between the difficulty of two-hand coordination means in terms of groups (P=0.001), but overall effects of different dosages of nicotine on 2HAND in both athletes and non-athletes was no significant (P=0.544).
