The aim of this study was to investigate the effects of providing skin conductance (SC) biofeedback on the performance of elite rifle shooters. Volunteer participants (n=10) were divided into experimental and control groups (n=5, in each group). After pretest, the experimental group, was educated about SC biofeedback, then participated in five shooting practice sessions while receiving skin conductance feedback. The control group, performed five sessions of their regular exercise. Both groups then took part in the posttest and a week later in the transfer test. The results of one-way ANOVA showed that the performance of the experimental group in the posttest and in the transfer test significantly increased compared to the pretest. Also, the results showed that the ability to adjust the arousal level of the experimental group at the end of the intervention, significantly improved. It seems that shooting practice along with receiving SC feedback has led to the self-regulation of shooters in providing an appropriate response to arousal and thus improving performance. In summary, the results of this study showed that athletic performance is improved by stimulating arousal levels and providing biofeedback.

One of the most important issues in community is health and progress people. Because of durability of a community depends on health each person. In this regard, the present study aims to compare anthropometric, biomechanical and psychological factors between university student and student girls done. Subjects of the study were 86 girls 15-17 years old and 113 university student 18-24 years old, took part randomly in this study. Measure anthropometric, biomechanical characteristic also psychological characteristics including general health (GHQ-28) and personality (NEO-FFI) were measured. The result of independent t-test showed that between percent fat and lean body mass, static balance and muscular endurance and all of the general health factors, there are significant differences between the two groups. In generally the subjects are in the border abdominal obesity and high risks associated health them. Doing prevention programs are essential. One of the most important proceedings for this group doing of physical activity and fitness and have a regular exercise program.

The present study was designed and conducted to investigate the psychological factors affecting the success and failure of athletes. The research method was survey. The statistical population included male professional athletes in group disciplines in the western provinces of Iran that complete and accurate information of them was not available. For this purpose, according to the available selection, 200 of these people were identified as the research sample. Finally, after distributing and collecting research questionnaires, 172 questionnaires were analyzed. The research tool included a researcher-made questionnaire. The results showed that a total of 24 identified components were classified into 4 categories of factors including motivational issues, environmental aspects, individual issues and executive issues. In other words, paying attention to motivational issues, environmental aspects, personal issues and executive issues can be effective in shaping the successes and failures of athletes.

Scaffolding is conceptualized as the provision of assistance to learners and the gradual withdrawal of the aid as the scaffoldee signals progression in their knowledge/skill and the capability to take over more responsibility. The present study sought to scrutinize the impact of metacognitive scaffolds intended to endorse metacognitive activities (i.e. planning, monitoring, and evaluation) on various aspects of oral proficiency namely, complexity, accuracy, and fluency. Sixty participants selected through a proficiency test and ranging in age from 16 to 27 took part in the study. Complexity was assessed by calculating the ratio of clauses to AS units in the participants' production. Fluency was measured by dividing the number of syllables by the total number of seconds and multiplied by 60, and accuracy was gauged as the percentage of clauses devoid of syntactic, morphological, and lexical errors to the whole number of clauses. The results of a number of t-tests and ANOVAs on pre and post-intervention oral performance revealed that metacognitive scaffolds could significantly enhance oral proficiency in terms of complexity, accuracy, and fluency. Implications for classrooms are discussed.

Body image like other aspects of mental section is a part of our personality which has evolution procedure and is disturbed and weakened in situations such as obvious disfigurement. The aim of this study was to compare body image between individuals with idiopathic scoliosis and healthy ones. This study was descriptive – comparative. 54 subjects (mean age 18.1) with idiopathic scoliosis completed Mendelson Body Image Questionnaire. Then, a control group was compared with scoliosis group. The reliability of the questionnaire was 0.82 using Cronbach's alpha coefficient. Scoliosis was diagnosed and measured by radiography. The collected data were analyzed by independent t test. The results showed a significant difference in body image between idiopathic scoliosis and healthy groups (P=0.01). Also, there was a significant difference in subscales of appearance satisfaction and attribution satisfaction between these two groups (P=0.03, P=0.00). There was no significant difference in weight subscale between these two groups (P= 0.17). Trunk deformity and secondary changes in shoulders and scapulas in those with idiopathic scoliosis may weaken their body image and may lead to some psychological impacts.
