The Relationship of Force Control and Adjustment of Dominant hand's Angle to selected Psychological Traits in Athlete and Non-athlete Students

The aim of this study was to investigate the relationship of force control and adjustment of dominant hand’s angle to selected psychological traits in athlete and non-athlete students. 120 participants including 99 male and 21 female athlete students (19-29 years old) from different sports and 120 non-athlete students from Tehran university (20 girls, 100 boys) attended in the study. Digital handgrip device and angle joint measurement device were used respectively to assess force reproduction and joint reposition. Profile of Mood States Questionnaire was used to measure mood states and to measure emotional intelligence we used Schutte’s emotional intelligence scale. To evaluate relationship between variables Pearson's correlation coefficient was used. The Z-Fisher was used for investing difference between correlation coefficients. The results showed that there was a significant relationship between POMS’s scores with force control and adjustment of dominant hand’s angle errors in both groups, although the relationship was stronger in nonathletic subjects. The findings indicated that negative mood states can lead to kinesthesis sense errors, but that is less effective in athletes. On the other hand, that there was not significant relationship between EQ’s scores with force control and adjustment of dominant hand’s angle errors in both groups, i.e. kinesthesis sense cannot be affected by cognitive control of emotion and longtime sport participation does not affect on their relationship.
