Fernandez et al. (2006) developed this instrument based on the push, pull, antipush, and anti-pull point of view. We required 243 Iranian elite competitive athletes (mean age = 25.19 years; 81% male) to complete the questionnaire. The factor structure of the P-ARDI was evaluated by explanatory and confirmatory factor analysis. The internal consistency was determined by Cronbach’s alpha. According to the results, four-factor solution principal component analysis accounted for 65.02% of the variance of the final 36-item version of the P-ARDI. The Cronbach’s alpha coefficient for the aforementioned factors was found to be greater than 0.7. In sum, the results suggest that the retirement decision process was found to be much more complex and multidimensional.

The purpose of the current study was to examine the effects of vision and amount of practice on accuracy and kinematic of dart throwing. 20 female students of righthanded who were all novitiate in the skill selected voluntarily and randomly assigned to full vision and No-vision groups.The subjects following participated in pretest, performed acquisition phase that consisted two level of modest and extensive practice (45 trials and 300 trials). 10 minutes after each level of practice, participants completed transfer trials in a no-vision and no-KR condition. Overall, Mixed ANOVA (2×3) in acquisition phase revealed that vision improved Dart throwing accuracy performance. Kinematic analysis revealed no significant difference between two groups in Wrist flexion, Angular displacement of elbow and Angular displacement of shoulder. Whereas after 300 trials of practice, there was significant difference between groups in throwing time and angular velocity of the dart. After extensive practice, Mixed ANOVA (2×2) showed that, withdrawal of vision resulted in specificity of practice effects on dart throwing accuracy, but results of kinematic pattern, regardless of the amount of practice did not support specificity of practice. 2462 motor behavior The relationship between passion to physical activity and life satisfaction in male students: The Dualistic Model of Passion (DMP) aghdasi mohamad taghi mohamad zadeh hasan ghavami akbar 1 11 2016 6 12 57 66 07 04 2017 07 04 2017 The aim of this study was to investigate the relationship between passion to physical activity and life satisfaction in male students. 383 male students were chosen through cluster sampling among various schools in Tabriz and completed passion scale (Vallerand, et al. 2003), and multidimensional life satisfaction scale for students (MSLSS, 2001). T-test and Pearson correlation test was used for data analysis. Results showed that students with Harmonious Passion to physical activity have higher levels of satisfaction with their family, life environment, school and friends than students with obsessive passion. The results also showed obsessive students have a higher level of satisfaction in self subscale compared with Harmonious students. In general life Satisfaction, the results showed that Harmonious students have more satisfied than the obsessive students.

The 16 participants of this study were divided into two groups of Skilled and Novice. The Skilled group was consisted of players who ranked as 8 top in national ranking at their age stage and the Novice group was consisted of players who recently learned the top spin skill. They performed 10 top spin strikes with emphasis on speed and accuracy. Movement kinematics were recorded and analyzed. There was a difference between these two groups in variability of intra limb coordination (p<0.05) and the Skilled group performed more consistent. However, there was not any differences between these two groups in movement control variables (all p>0.05). This study showed that the skilled performers have more consistency in their movement patterns, while it could be no difference with novice performers in control variables as cause of task constraints. 2464 sport management Commitment in Women's Football Pro League of Iran abyari meysam nezhad sajadi seyed ahamd sharifian esmaeil 1 11 2016 6 12 75 80 07 04 2017 07 04 2017 The purpose of this study is investigating the effect of sport orientation on sport commitment in Women's Football Pro League of Iran.
