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.

The main aim of this study was to investigate the effect of different levels of impulsivity on learning of skills in open and closed environments. Participations were forty-eight male with 10 to 12 years old that signed in low impulsivity, med impulsivity, high impulsivity and control groups (combined group) in accordance to the distribution of impulsivity scores. Before and after basketball skills training program, Harrison’s basketball shooting test was used to evaluation of performance and learning of skills in open and closed environments during pre-test, post-test, retention and transfer test. The results showed a significantly differences between groups for attentional functions (p=0.0001). The results of post-test and retention showed advanced performance in open environment with the increased levels of impulsivity (p=0.003). While about closed environment, progressive performance was aligned with Low levels of impulsivity groups (F=0.001). But in the transfer tests, differences between the groups were not significant (F=0.09), that was performed under the competitive goal condition. It is possible that impulsivity has a facilitator and an attenuator role in learning of various sportive skills, perhaps in open and closed environments.

The purpose of the present study was to evaluate the effect of perceptual-motor activities on the academic performance of female students in the first grade and the sixth grade.The students of each grade (50students in the first grade and50 students in the sixth grade) took part in the Lincoln-Oseretsky Motor Development test for assessing perceptual-motor function and Raven intelligence test for assessing cognitive function. Teacher assessments of math and Persian as an indication of their academic progress were also considered.Based on the results , the students of each grade were divided into two groups of experimental and control (n = 25). The experimental group participated in an eight-week training course including a variety of exercises and perceptual-motor activities. The training course consisted of 45 to 60 minutes sessions three times a week. After this period, students in both groups were reevaluated by assessing their academic performance. The results obtained from t-test analyses showed that, unlike the six graders, perceptual-motor activities had a positive impact on academic performance of first grade students. Keywords: Academic performance, Concrete operational stage, Perceptual-motor exercise, Preoperational stage.

The purpose of this study was to compare instructor-based and parent-based interventions on motor development in 7 to 10 years old children with developmental coordination disorder. Participants consisted of 84 girls and boys from 8 elementary school at 4, 8 and 13 Tehran educational zones; they were screened by developmental coordination disorder questionnaire, then randomly divided into three groups: instructor-based, parent-based, and control. Two experimental groups carried out skills training for 12 weeks consisting, 36 sessions, each session 45 minutes. All participants were assessed before and after interventions with Movement Assessment Battery for Children; Second Edition. The result of MANCOVA and ANCOVA tests showed that both experimental groups significantly in the total score of motor development (p≤0.05) and its components (manual dexterity, balance, aiming and catching) had higher score than the control group (p≤0.017), and of course Instructor-based group in the aiming and catching subscale had better performance than parent-based group (p≤0.05), that demonstrates positive impact of group environments. In summary, although both interventions help to improve motor development in children with developmental coordination disorder, instructor based intervention is more beneficial in some of the components of motor development.

Aim: This study aimed to determine effect of self-control of task difficulty on accurate and movement pattern golf putting. Methodology: Thirty novice undergraduate students (14 Female and 16 male; average age 21.1 ± 1.64 years) were quasi-randomly assigned to two groups. Before performing each trial during the acquisition phase, the self-control group was told they could choose any of the pre-set distances from the target: (25, 50, 75, 100, 125, 150, 175 and, 200 cm). Each self-control participant’s practice schedule was served as the predetermined practice schedule for each corresponding yoked participant. Participants practiced eight blocks of 10 trials. To analyze the radial error (in acquisition and tests phases) and the movement pattern score (in tests) mixed variance analysis with repeated measures on the last factor was used. The movement pattern score in acquisition phase was analyzed using t test. Results: Based on the results, radial errors across different groups in the acquisition phase did not vary, but the radial error of the self-control group in retention, single task transfer and dual-task transfer tests was lower compared to the yoked group (ps < 0.001). In acquisition and test phases, the golf putting movement pattern was better than that of yoked group (ps < 0.001). Conclusion: The efficacy of self-control of task difficulty is explained with reference to the challenge point framework.

Aim: One of the issues that have been considered more than before is the issue of aging. An aging is a period that is accompanied by gradual, progressive and spontaneous erosion changes in most physiological devices and functions of the body. One of the widespread problems that occur in the aging process is the loss of balance, increased fluctuations and the risk of falling. Falling down is one of the most common and most serious problems are aging. For this reason, today, many researchers have drawn attention to the various ways in which elderly people develop their balance. Recently, some researchers have found that the use of cognitive strategies such as self-talk can improve the performance of motor tasks. Self-talk, essentially has two main instructional and motivational functions. Motivational self-talk through increased self-confidence and instructional self-talk by enhancing focus on techniques improve their sports performance and learning skills. On the one hand, it is important to increase the effectiveness of the instructions in order to focus on the focus. Wolfe's researches (1998-1992), given the constrained action hypothesis in most sports skills as well as balance skills, suggest that the use of external attention in comparison with internal attention during the skill leads to better performance and learning. Several studies have been conducted on motivational and instructional self-talk about different athletic skills and different skill levels that have led to a variety of outcomes, but few studies have considered the scope of balance. So, the aim of this study was to evaluate the effect of attentional focus types as the self-talk form on static and dynamic balance in elderly women using instructional self-talk focus strategy. Methodology: The present study was a quasi-experimental study with pre-test and post-test. The experimental group included instructional self-talk with internal focus and instructional self-talk with external attention as well as a control group. The population of the study consisted of all elderly women living in the nursing home in Qazvin who 45 people (66.75 ± 5.65 years) were selected according to the inclusion criteria. Inclusion criteria included Lack of movement restrictions, non-fracture in the lower extremities in the past year and the lack of use of neurological drugs. After the pre-test they were randomly assigned to groups. The control group without self-talk, self-talk group with internal focus and self-talk group with external focus practice their balance skills during the five sessions. At the end of the fifth session, the post- test was conducted using static balance (stork) and dynamic balance (timed up and go) tests. In the stork test, the subject must stand on top of his leg, lift the other leg and stick to the knee of the leg, and simultaneously place his hands on the iliac crest of the pelvis. The time that a person could stand open with his eyes was considered as an indicator of his static balance ability. Each subject performed the test three times and the highest time was recorded. The errors that caused the test to be stopped include lifting the hands from iliac crest of the pelvis, detaching the leg from the knee of the foot and any movement on the foot of the reliance.Each subject performed a three-time test of timed up and go, and his best time was recorded. Since the subject was announcing his stand, the timer began to work, and the timer stopped when it hit the subject back with chair. The self-talk group with the instruction of focus of the internal attention, repeated the words "knee and foot" before each loud performance, which meant "bending slightly knees and maintaining the balance on the foot", and the external attention group referred to the term "target and wall" Which meant "looking at the target mounted on the wall.Results: One-way ANOVA, mixed ANOVA and repeated measure ANOVA were used to analyze the data. Data was analyzed using SPSS software version 20. The significance level was considered 0.05. The results showed that both self-talk groups performed significantly better than the control group in static balance.Conclusion: However Self-talk interferences with both types of attentional focus; it was not a significant difference in the dynamic balance of elderly people (P≥0.05). Taking the results into consideration it can be concluded that, self-talk with internal and external focus instructions can be considered as a cognitive strategy to improve the static balance of elderly people.

The role of the training is to improve the symptoms of Parkinson's disease. The purpose of this study was to compare the effects of exercise intensity on learning, spatial memory and anxiety behaviors in rat with impair . In this study, 24 male rats were randomly divided into 5 healthy control groups, Parkinson's control, Parkinson's (low, moderate, and high intensity) exercises. The creation of the Parkinson's Model was injected intra-brain-6-hydroxydopamine. To assess learning and spatial memory, Morris water maze test and Counting Counting were used as an indicator of anxiety behavior. Data analysis was done by one-way ANOVA at a significant level (P <0.05). Injection of 6-hydroxydopamine increased the duration of the platform and destroyed spatial memory (P <0.05), Although all three types of space memory training decreased significantly in Parkinson's rats significantly (P <0.05), high intensity exercise showed the greatest effect on learning and spatial memory (0.05). (P <0.05), there was a significant difference between the high and low intensity training groups (P <0.05). This difference was not significant between the moderate and low intensity groups in most of the variables (P <0.05). Different intensities, especially high intensity, improve the parameters of spatial memory
