The aim of this study was to predict expert archers’ performance on the basis of
psychological factors such as arousal, activation, anxiety, motivation and
personality characteristics with an emphasis on extraversion / introversion
dimension. In this predictive correlation study, 34 expert archers were randomly
selected as the sample of the study out of the archers of national team (statistical
population). Skin conductance level was measured to assess arousal. To determine
trait anxiety, Sport Competition Anxiety Test (SCAT) and for state anxiety,
Competitive State Anxiety Inventory (CSAI-2) were used. Sport Motivation Scale
(SMS) was used to determine motivation. Extraversion / introversion level was
measured by eysenck personality questionnaire. Pearson correlation coefficient
was used to determine the level of correlation and linear multivariate regression
was used to predict subjects’ performance. The results indicated a significant
positive relationship between subjects’ performance and arousal, activation,
motivation (intrinsic, extrinsic) and extraversion / introversion whereas there was
no significant relationship between their performance and anxiety (trait, cognitive,
somatic) and consequently they could not predict performance. Also, the results
revealed that arousal and activation (P

The present study aimed to examine the effect of contextual interference on acquisition, retention and transfer of coincidence anticipation task with constant, increasing and decreasing speeds. 36 male physical education participants from Shahid Beheshti University were voluntarily selected and randomly divided into three groups (12 subjects each group) and performed coincidence timing tasks with Bassin anticipation timing. In this research, three separate experiments were used. Experiments consisted of constant speed, increasing speed and decreasing speed. Subjects participated in pretest, acquisition, blocked retention, random retention and transfer tests. Absolute temporal errors were analyzed by one-way ANOVA, ANOVA with repeated measures and Bonferroni post hoc tests (P

The main of this research was to investigate the effect of a psychological training program on mental health of elite basketball players. This research was semi–experimental with pretest posttest and a control group. The population consisted of all basketball players from Iran basketball super league (N=150). They were divided into two teams: experimental and control group. Minnesota multiphasic personality inventory – 2 restructured form (MMPI – 2RF) was used to collect data which consisted of validity scales profile as well as 4 profiles including clinical, somatic/cognitive and internalizing scale, externalizing scale, interpersonal and interest scale and psyche scale. This inventory consisted of 338 questions and showed high validity and reliability coefficients (P

The aim of the present study was to investigate the effects of various scheduled practices (self-regulated and non-self-regulated) on the acquisition, retention and transfer of simple and complex tracking tasks. 96 right-handed undergraduate students (age rang: 18-24 years old) volunteered to participate in this study (48 females, 48 males). These students participated in physical education classes (1 & 2) in their first semester of 1387-88. Participants were assigned to one of eight different groups (n=12), which differed in types of tasks performed (simple tracking or complex tracking) and the practice schedule used (blocked, random, self-regulated, or yoked). The method was quasi-experimental. These tasks were designed as software and appeared on a computer monitor. The movement time and movement error (click) were assigned as scores in different groups. After the pretest, the subjects practiced 8 16-trial blocks in 2 sessions. 24 hours later, they participated in the retention and transfer tests. The data were analyzed by mixed factorial ANOVA and Bonferroni post hoc test. The results showed a significant difference between various scheduled practices and type of task in various stages of movement time (P
