AbstractThe present study was conducted to compare the effectiveness of two different methods to enhance free throw shooting among young basketball players. One method is based on mindfulness(MSPE) and the other is based on mental imagery(MI). This is a semi-experimental study and in terms of data collection, the design of the study is experimental with pre-test, post-test and a control group. Statistical population consisted of young basketball players in Tehran from whom 60 players were selected through convenience sampling and put into the following three groups: mindfulness group, mental imagery group and control group. Statistical analyses were presented in two sections: descriptive statistics and inferential statistics. Descriptive statistics included participants’ characteristics, distribution of data and the variables’ mean and standard deviation. Shapiro-Wilk test was also used to determine whether the data were naturally occurring. Then, the data were analyzed through inferential statistics using paired-samples T-Test, ANOVA, Leven’s Test, Games-Howell Test and Bonferroni post hoc Test to test the hypotheses. Significance level of the study was set at 0.05. The results obtained from the pre-test and post-test of both mindfulness and mental imagery groups showed the participants’ performance was significant with mean differences of 4.15 and -2.55 respectively. Also, the final findings of the study indicated that treatment in mindfulness group was more effective than that of mental imagery group, in improving free throw shooting (P=0.2).Key words: basketball, Free throw, Mindfulness, Mental imagery, Sport performance

The aim of this study was to investigate the effect of feed forward augmented information in model observation on learning mini basketball free throw skill in children. For this purpose, 45 children (10 years old) were selected as the sample by convenience sampling method and were divided into three groups: feed forward augmented information + observation, observation + KR feedback, and control (C). The research method was semi-experimental and research design was pretest-posttest and retention test. The task used in this study was mini basketball free throw skill. Firstly, the participants performed 15 trials in the pretest. The acquisition phase consisted of 6 blocks of 15 trials of observation followed by physical training. The retention test was performed 48 hours after the last training block in 15 trials. The data were analyzed by mixed analysis of variance, between-group analysis of variance and Tukey post hoc test. The results showed that both at the acquisition and retention phases, feed forward augmented information + observation group who were knowledgeable about the quality of the model prior to the observation showed better performance than the other two groups (P<0.05). Generally, these results showed that knowledge of the model performance before observation can make learning of a throwing task more significant than the time when they were knowledgeable after the observation. Therefore, it is suggested that feed forward augmented information on the quality of the model before observation should be used to improve the performance of the subjects.

Various researches know lateral preference of eye and hand pattern as one of the important factors of performing sports skills. This study aimed at investigating the effect of lateral preference of eye and hand pattern on learning basketball free throw skill. From 3000 female students of Shahid Chamran University of Ahvaz, 60 subjects (age range 19-22 yr) were selected purposively as the sample using a researcher-made questionnaire of individual information and sporting background, Edinburgh Handedness Inventory (Oldfield, 1971) and hole card (Durand and Gold, 1910) and were assigned to two control and experimental groups (each group: 15 unilateral subjects and 15 crossed-lateral subjects). Firstly, pretest of basketball free throw was conducted. Then, practice protocol was performed for 8 weeks (24 sessions, 3 sessions a week). During this period, 6 posttests were administered to determine learning stages and one week after the last posttest, the retention test was conducted. The results showed a significant difference between unilateral and crossed-lateral (experimental group) subjects in the cognitive (sig=0.000) and associative (sig=0.000) stages of the acquisition of basketball free throw and the unilateral subjects had a better performance. Whereas there was no significant difference between unilateral and crossed-lateral subjects in the autonomous (sig=0.105) and retention (sig=0.086) stages. Finally, the results showed a difference in performance between experimental and control groups in favor of experimental group. According to these results, it seems that long practice and autonomous skill in unilateral and crossed-lateral subjects matched their performance and eliminated their differences. Therefore, coaches are recommended to identify talented subjects after a lot of practice in order to not generalize the result of performance to learning.
