Introduction: The present study aimed to determine the effect of imagining the play strategies in comparison with imagining the motor skills on performance during a sports competition course.Methods: Participants were 30 (19 men, 11 women) karatekas who were evaluated as upper than moderate in terms of performance level. In the beginning, participants' ability and past experiments in motor imagery were assessed. Then, they took part in a quasi-experimental design of one of three strategic imagery, movement imagery, or control groups. Each person immediately after combatting with an opponent performed the required action depending on the group and finally competed against the same previous opponent, again.Results: The results showed that karatekas had excellent imagery ability, especially in preserving the temporal characteristics of the movement, and at the past competitions, specifically before their matches, they had used both cognitive-general and cognitive-specific imagery. Also, the nonparametric analysis demonstrated that in the quasi-experimental design, the strategic imagery group gained a higher point difference during the post-test, however, the movement imagery or control group did not differ significantly.Conclusion: The research findings revealed that strategic imagery has more advantages compared to skill imagery, suggesting that strategies of play can be used between the matches as an effective factor in sports success.

Compared to the individual training method, pair and participatory training method are methods in which people in groups of two or more contribute learning motor skills, and it seems that this method has the characteristics of an optimal educational environment increasing the efficiency and effectiveness of the training. The purpose of this study was to compare approaches of individual, pair and participatory training on learning of Shotokan karate. In this study, 36 female students aged 10-9 years were selected and divided into three groups after 12 sessions of initial training in HianShodan kata pre-test. Then, after 3 months of kata practice, by individual, pair and participatory practice, their performance was evaluated and a retention test was taken one week later. Statistical analysis of data was performed using repeated measures analysis of variance test. The test results showed that the participants' progress scores (F = 174.14, P = 0.001), the interaction of progress in the type of exercise (F = 5.1724, P = 0.001) and the difference between the exercise groups (F = 6.08, P = 0.006) is significant. The results of pairwise comparison showed that there is significant difference between individual and pair education groups; but difference between individual and group education groups was not significant. The pair training method, in addition to being cost-effective in terms of energy consumption and training space, is more effective than traditional kata training methods in karate. In addition, this method of practice will be useful in the socio-emotional development of the learner.

According to numerous studies in sport psychology, it is proved that optimal athletic performance relates to many psychological factors and personality and psychological characteristics influence athletic development. The aim of this study was to investigate and compare mindfulness, emotional intelligence and mental toughness in successful and unsuccessful karate athletes in Iran men’s karate super league. This research was casual-comparative and the population consisted of Iran men’s karate super league in Kumite section in 2015. Primary data were collected by convenience sampling method from 70 athletes of all participating teams- especially two high ranking teams and three low ranking teams- in karate super league. After the data of the number of competitions and their results for each athlete were collected, the optimal performance of karate athletes was calculated and two successful and unsuccessful karate athletes groups were determined (each group 30 subjects). The form of content, the demographic questionnaire, Sport Mindfulness Scale, Schutte Emotional Intelligence Questionnaire and Mental Toughness Questionnaire (48 items) were used. The normal distribution of data in both groups were examined using the K-S and Shapiro-Wilk tests. The results of independent t test showed that the difference in mindfulness was not statistically significant between successful and unsuccessful karate athletes, but the emotional intelligence and mental toughness between successful and unsuccessful athletes were significantly different. Overall, it can be stated that a major part of these findings emphasize the role of the psychological characteristics in the sport performance and success of the two groups of elite karate athletes who have the highest rank in Asia and world karate.

Nowadays, numerous studies have shown that optimal athletic performance is related to many psychological factors. This paper aimed at comparing motivation and perfectionism of successful and unsuccessful karate athletes in Iran men’s karate super league. This study was casual-comparative and the population consisted of karate athletes of Iran men’s karate super league in 2015 in Kumite section. Primary data were collected by convenience sampling method from 70 athletes of all participating teams (especially two high ranking teams and three low-ranking teams) in karate super league. After collecting the data of the number of competitions and their results for each athlete, the optimal performance of karate athletes was calculated and two successful and unsuccessful groups were determined (each group 30 subjects). The demographic questionnaire, the sport motivation scale, and the sport perfectionism scale were used in this study. The K-S and Shapiro-Wilk tests were used to investigate the natural distribution of data. The results of independent t test showed a statistically significant difference in adaptive perfectionism (positive) between successful and unsuccessful athletes. However, there was no significant difference in maladaptive perfectionism (negative) between the two groups. Furthermore, the Mann-Whitney U test results showed that the difference in all motivation subscales was not significant between successful and unsuccessful karate athletes. Finally, it can be stated that some findings emphasize the role of psychological characteristics in sport success and performance in the two groups which have in the highest rank of Asian and world karate.

The aim of the present investigation was to determine the effect of two karate
techniques on the reduction in stereotypic behaviours in three 5-year-old boys with
autistic disorders. The study included three boys with autistic disorders. A singlesubject
method with A-B-A design was used. Participants of the present study were
required to exercise two karate techniques (Zuki and Mae-Geri) for 12 weeks.
Changes in the severity of stereotypic behaviours were assessed by Gilliam Autism
Rating Scale (second edition) during intervention process and during one month
after intervention with one-week intervals. Results showed that with respect to
descriptive statistics and visual analytics, the karate techniques had an effect on all
three participants (PND=100% for first and third participants, PND=50% for the
second participant) and this reduction was maintained one month after the end of
the intervention. The findings of the present study indicated that teaching karate
techniques to autistic children dramatically decreased their stereotypic behaviours.

The aim of the present study was to examine the hypothesis of the specificity of practice regarding training place (to determine whether learning a sport skill was specific to the training place). Participants were 30 adolescent female students (mean age 11.50±1.50 years) who performed 10 sessions of learning perceptive-motor skill of Kata in Karate. After they finished Kata sessions, retention test was performed in the training place and transfer test in a different place and Kata scores were measured. To analyze the data, independent t test was used. Results showed that the subjects achieved their peak performance in the training place while their performance deteriorated significantly in the different place. It seems that the performance of the task was related to the place of training. The findings of this study provided evidence to support the specificity of practice hypothesis.

The aim of this research was to investigate the situation of talent identification process and to collect Karate related indexes in Iran. For this purpose, 63 karate subjects, male (N=31) and female (N=32), participated and filled in 3 special questionnaires to identify present and optimal situation of talent identification and most important aspects of biometric, motor capabilities, psychological capacity and skill indexes. The data were analyzed by Pearson coefficient correlation (P?0.05). The results showed that although the reaction time of hand and foot, flexibility, coordination, hand and foot length, agility and sergeant jump were the most important anthropometrical factors related to successful performance, but the reaction time of hand and foot, flexibility and coordination were significant predicators of discriminating athletes. In motor capabilities, the endurance of cardiovascular system played the main role and was an important predictor. In psychological capacity, two factors of concentration and self-confidence had a critical role and only concentration was a significant predictor. The results of this study showed no pattern for talent identification in Iran from coaches and athletes’ viewpoints.
