Aim: The use of psychological interventions in sport to enhance performance has become increasingly popular. However, the effectiveness of these interventions has been questioned by some sports psychologists. Educationally-based psychological interventions have produced significant increases in performance. It was found that 38 of the 45 studies examined (85%) had found positive performance effects, although causality could only be inferred in 20 of these studies. These interventions could be classified as relaxation-based, cognitive, cognitive-behavioural or behavioural in nature. The purpose of this study was to evaluate the effect of physical practice, mental imagery and music on the improvement of basketball shooting skill.Methodology: In this quasi-experiment study, 45 students (19-22 years) were randomly selected from elementary schools and classified in the three experimental groups consisting 15 participants. Physical practice, mental imagery and imagery along with music were the order of three experimental groups. The data was collected using modified basketball shooting in this study.Results: Statistical analysis was conducted with the descriptive statistics tests consisting kolmogro-smirnow, T test and one way-anova. The result of present study indicated significant differences (p< 0.05) between pre and posttest of physical practice, physical practice with mental imagery and physical practice with mental imagery and music.Conclusion: Based on inter group comparison, it can be said that mixed method was more efficient than other two methods and significant difference was not reported between physical practice with mental imagery and physical practice. Thus, it is suggested that different teaching methods should be used for promoting training programs.

Motor and field characteristic change is called variability of practice that the learner experiences during skill practice. This study was designed to compare the effect of variability of practice on the basketball free-throw learning in implicit and explicit conditions. For this purpose, 40 male (20-27 years old) Shahid Beheshti University students were voluntarily selected and were randomly divided into four groups: implicit learning with variable practice, implicit learning with constant practice, explicit learning with variable practice and explicit learning with constant practice after a pretest. Variable practice groups performed 45 throws from 1.5, 3 and 4 meters distances from the target while constant practice groups had these throws from 3 meters distance each session for 6 days. Implicit learning groups performed a secondary task of counting from 1000 in a reverse order for every triad number along with the free-throw task. But the explicit learning groups performed the free-throw task without a secondary task. The acquisition, retention (48 hours after the last acquisition phase) and transfer (from a 4.6 meters distance) tests were conducted. For data analysis, analysis of variance with repeated measures, two-way ANOVA and Tukey post hoc test were used (P<0.05). The results showed that all groups improved in the acquisition phase (P>0.001) while the main effect of learning and practice was not significant (P>0.05). In addition, in the retention and transfer phases, the main effect of learning type, practice type and the interaction between practice and learning was not significant (P>0.05). Therefore, the results of the present study disagreed with Schmidt's schema theory.

This study examined the effect of general and specific practice on the presence of a special skill. 24 healthy university students with no history of basketball were selected. After a pretest, they performed constant and variable practice (in constant and variable groups) for 5 weeks and 3 sessions per week. A performance test was conducted at the end of every week and retention and transfer tests were conducted after 2 days of detraining. The ANOVA test with repeated measures was used to analyze data. The results showed that the constant practice was better during performance in practice sessions and the variable practice was better in transfer of the mentioned skill. Also, no differences were observed in basketball throw from the penalty location between constant and variable practice groups in retention test. This finding did not support the hypothesis of special skill in basketball throw skill. Therefore, the coaches and players are recommended to use variable practice for more learning of basketball throw skill.
