Mental toughness is the ability to increase the flow of the positive energy against obstacles. The aim of the present study was to compare mental toughness of male and female skilled and novice climbers. 130 climbers that were randomly selected and divided to skilled and novice groups. Data were collected through Mental Toughness Questionnaire of Sheard, Golby and Van Wersch. Data were analyzed using multivariate analysis of variance and LSD post hoc test (P≤0.05). The results showed that the main effect of skill was not significant but the main effect of gender and interaction between gender and skill were significant. Further analysis on the data showed that the highest mean belonged to the male skilled climbers in confidence component and the lowest mean belonged to female novice climbers in control component. Male skilled climbers were also significantly higher in all three subscales of confidence, control, and stability than female skilled climbers. So, it is suggested that according to the nature of climbing which is an endurance and risky exercise, merely being skilled at developing the mental toughness of climbers was not a criterion and other factors such as gender and its interaction with skill play an important role as well.

The vital role of exercise in many aspects of daily life and somewhat cognitivefunctions are acknowledged but a point that has recently gained researchers'attention is to investigate the effect of different types of exercises on cognitivefunctions and the mediating mechanisms of this effect. The aim of this study was todetermine the effect of two types of endurance and resistance exercises on thelevels of attention and BDNF of sedentary students. Therefore, 46 sedentarystudents from University of Tehran (mean age 24.3+1.8 yr) were assigned to threegroups: endurance, resistance and control after the Stroop pretest. After bloodsamples had been collected, the subjects continued their exercise protocol for fiveweeks. Finally, at least 48 hours after the last session, the Stroop test wasperformed and blood samples were collected in order to eliminate the temporaryeffects of exercises. For data analysis, Kolmogorov–Smirnov test, paired sample ttest, one–way ANOVA, MANOVA test, Dunnett's T3 post hoc test and Pearsoncorrelation coefficient test were used (P≤0.05). Results showed a significantimprovement in the response time of Stroop test in both endurance and resistancegroups while expression of BDNF significantly increased only in endurance group(P<0.05). The control group showed no improvement in any variables. In addition,there was no significant difference between the effect of two types of exercise onthe response time of the Stroop test and expression of BDNF (P>0.05). There wasno significant correlation between the variations of response time of the Stroop testand expression of BDNF (P>0.05). Finally, this research indicated that exercisecan improve cognitive functions, but there was no significant difference betweenendurance and resistance exercises in response to this question that which activitywas more useful.
