The psychological factors plays a decisive role in the success of elite athletes at the highest levels competition, where the fitness of athletes reaches to the highest possible level. The purpose of this study is to investigate the relationship between Psychological factors and physical fitness of elite young Iranian kabaddi players. For this purpose, 28 young players invited to the second camp of kabaddi Iranian national team in the age range of 17-19 years were selected. In order to assess the mental toughness and Mindfulness Respectively Sheard et al mental toughness questionnaire and a questionnaire was used Thienot et al. Also, the field test of bulk, 36 meters, two-way jump, bench press and leg press test was used to measure physiological characteristics. The results of the Pearson correlation coefficient showed that there is a significant relationship between the subscales of mental toughness and some the subscales mindfulness and physiological characteristics elite players with Iranian kabaddi. Also, there is the significant relationship between mental toughness and some subscales mindfulness and physiological profile. From other findings of the study, showed the players that could wear the national team shirt had higher Mindfulness than the players had been strikethrough.
Discussion and elite players with Iranian kabaddi players have equal toughness physiological profile but the players that could wear the national team shirt and probably the high level of mindfulness can improve the power performance tests.

The purpose of this study was to investigate the effects of Pilates exercise on body image, body mass index and fat percentage in sedentary women. This research was Semi experimental study. The subjects contain 41 healthy inactive women were randomly divided into three groups. experimental and control groups with mean age and body mass index 21.88 ± 2.17 and 23.06 ±3.57 kg/cm2 respectively. The experimental groups completed eight-week Pilates training and control group continued their daily activities without intervention.  Data were collected before and after body image test and other measurements. Data were analyzed by Student's t test at the significant level of 0.05. The results of this study showed that eight weeks of Pilates training in the exercise groups caused to significantly (P<0.05) changes in all subscales of cognitive-perceptual structures of visual perception of the image and one of the subscales of emotional structures as negative impacts in compare with control group. But had no significant effect on other subscales emotional structures-body image (P>0.005). Also there were significant change in body mass index (P=0.024) and body fat percentage (P=0.017) after exercise compared with the control group.  The findings show that although Pilates training could not reduce the body weight (P=0.153), in a short period of eight weeks, but it can change in their attitude. This can widely effect on mental health and related indicators.

Present study aimed to study the mediating role of efficient and non efficient coping strategies in relationship of positive and negative perfectionism with sport burnout. Methodology was correlation. 120 participants were selected mono cluster sampling thorough semiprofessional footballers in Tehran. Data were collected using questionnaires of Lazarus's coping strategies, Terry-short & et al's perfectionism and Maslach's burnout and analyzed by tests of Pearson correlation and stepwise regression. The results indicated that there is a significant relationship between positive and negative perfectionism with sport burnout in semiprofessional footballers and efficient coping strategy negatively and non efficient coping strategy positively mediate in relationship positive and negative perfectionism with sport burnout (P<0.01). Results provide some evidence to suggest that the mediating role of efficient and non efficient coping strategies in relationship positive and negative perfectionism with sport burnout was partial. Efficient and non efficient coping strategies reduce the effect of positive and negative perfectionism on burnout, but this effect wasn't complete. Therefore, in order to reduce sport burnout was suggested to attend to athletes' perfectionism and prompted efficient coping strategies

The purpose of this study was to investigate relationship between self-talk style and self-handicapping in soccer players of Urmia. In this descriptive- correlational study 260 soccer players of Urmia (Range of age 16-32, 230 male and 30 female) voluntary participated. To collect the data Self-talk questionnaire and self-handicapping questionnaire were used. To analyzed the data descriptive statistic, Pearson’s correlation coefficient, regression analysis were used. The results of Pearson’s correlation coefficient indicated that there is no significant relation between positive self-talk and self-handicapping, But there is a negative significant relation between negative self-talk and self-handicapping. Moreover the results of regression analysis also show that self-talk can predict self-handicapping. The results indicate that not should probe root of act only in the brain and mental life he but voluntary action and human behavior must be analyzed with regard to communications.

One of psychological interventions that can be effective on improving performance and learning behaviors is at the focus of attention. Thus, the aim of the present study was to determine efficacy of instructions on the focus of attention of suprapostural task on learning of postural control in boys with 9 to 12 years old. In this study, 45 boy students of one of the Malayer city schools were participated, and divided into three groups (15 people), including: external attention, internal attention and control group randomly. The participants were asked to keep their postural control by using instructions on suprapostural task. Instructions included attention on the bar horizontally held in their hands (external attention), their own hands (internal attention), and no instruction (control). The result showed that learning process in both internal focus group (P=0.022), and external focus group (P=0.04), is significant compared to the control group. However, no significant differences were found in learning between external focus group and internal focus group (P=0.794).  The findings support of applying the attention instructions as an effective strategy to improve learning. Also the fact that children can take advantage from the attention instructions, has important applications for physical education.

Anticipation skill is a strategy to reduce the response time or even reduce the processing steps that is normally used to response to a stimulus. The aim of the present research is designing and building software that has the ability to measurement accuracy of temporal anticipation. To check the validation, 30 participants (male students) who participated voluntarily from the Faculty of physical education of Tehran university. Executive software environment dimensions and speed of stimulus and Length of stimulus path are according to fit the dimensions of Digital type speed anticipation reaction tester. With the difference that a few other speed options we've added in software. The software is designed in such a way that uses automatically maximum amount of screen size. The distance of person from screen is calculated proportional to the speed anticipation device manually. For the validity and reliability, we use correlation of Pearson assessment between application data with Digital type speed anticipation reaction tester model (TAKEI_1108). In determining the validity of software, Pearson correlation analysis results did not show a significant difference between the parameters of the software and the device and the highest level of correlation is reported for the slow speed r = 0.84 and fast speed r = 0.86. In determining the validity, the Pearson correlation did not shown a significant difference between the parameters of the two tests and highest correlation is reported for fast speed r = 0.90 and 0.91 for slow speed. According to what was said it is concluded that the “anticipation timer software “is software that with the high amount of validity and reliability, estimate the anticipation speed skill.

The purpose of this study was to achieve a non-pharmacological effective way to modify behavioral problems in mothers with ADHD children. The statistical population at Qom city was determined by a general call for mothers with ADHD children, and 20 subjects were selected as samples through simple random sampling.
The research samples were randomly assigned into two equal groups of experimental and control group, and pre-test, post-test and follow-up tests were conducted on them. The experimental group experienced aerobic training 8 weeks, per week 3 sessions for 45 minutes. Anxiety and depression questionnaires of DASS-21 (1995) and life orientation of Sheyer & Carver (1985) and Happiness of Oxford (1989) were used. The ANCOVA’s statistical model was used to analyze data. The findings showed that aerobic exercise in the posttest and follow-up stages reduced the depression and anxiety of mothers of ADHD children and increased their life orientation and happiness in the experimental group. According to the findings of this study, it is suggested that aerobic exercises be used as an appropriate therapeutic strategy, free of side effects, and available to improve the physical and mental health of mothers with ADHD children.
