The aim of this study was to investigate relaxation and mindfulness on sports anxiety in female adolescents.

The participants of the present study were 45 adolescent female student athletes from Tehran province with an age range of 11 to 15 years who were selected by convenience sampling. All subjects were physically and mentally healthy. The research samples were divided into three groups of control, relaxation and mindfulness and two experimental groups (relaxation and mindfulness group) were intervened. The Martens Competitive Anxiety Questionnaire was filled out by the subjects before and after the intervention. Combined analysis of variance test was performed using SPSS software version 24 to examine intra-group and inter-group changes.

The results showed that all interventions reduced physical and cognitive anxiety. The mindfulness group had a greater reduction in physical and cognitive anxiety, but the imaging and relaxation groups did not differ significantly in any of the research variables.

The mindfulness group had a greater decrease in physical and cognitive anxiety and their self-confidence scores were higher than the rest of the relaxation and control group.

This study was designed to investigate the effect of 8 weeks Core‌‌stability and corestability_mindfulness exercises on balance performance In female older adults in nursing Centers of Kermanshah.

Was a semi experimental study, With pre-test, post-test design and control group. After selecting the center randomly, 30elderly women between eligible volunteers, randomly selected and divided to experimental-groups1,2 & control-group. Experimental group1 performed corestability_mindfulness exercise, experimental group2 performed corestability exercise, also control group continued their usual daily life. In pre-test, static balance was measured using Sharpenedromberg test and dynamic equilibrium using berg test. Experimental group1 and2, for 8weeks and 3weekly sessions each 45minutes, received their special exercises. Then the post-test was conducted with the same pre-test procedure. Data analysis was performed using Paired t-test, One-way analysis of variance and Scheffe Post Hoc.

The findings showed that performance of the experimental group1 and2 have been significantly improved from pre-test to post-test. The difference between groups was significant in comparison between groups; the results of scheffe posthoc test showed that the experimental group1 compared with control group had a significant different. But there was no significant difference between other groups.

The results show that combining core stability physical exercises with mindfulness exercises can be beneficial for the balance of femahe older adults.

The aim of the present study was to investigate the effect of a cycling endurance activity on serum concentrations of surfactant D and Clara proteins. The present study was a quasi-experimental study with two stages of pre-test and post-test. The statistical sample of the research was 20 cyclists (elite cyclists = 10 people, recreational cyclists = 10 people) in Tehran province with an age range of 20-30 years. In this study, Clara cell and surfactant D proteins were measured after one session of endurance activity with an intensity of 70-80% of maximum oxygen consumption for 30 minutes. After research interventions, serum levels of Clara cell protein and surfactant D protein were assessed. Data analysis was performed using descriptive statistics (age, height and weight) and inferential statistics (Independent and dependent t-test) using Spss software version 25. Findings showed that the serum concentration of Clara cell after training intervention was significantly increased in both groups of elite and recreational cyclists. Also, serum levels of D-surfactant protein increased significantly after training intervention only in elite cyclists. The results showed that one session of endurance activity may increase the serum levels of Clara and surfactant D proteins in athletes.

The aim of this study was to compare the effect of forced exercise with treadmill, immobility stress and imultaneous application of stress + treadmill exercise on learning and spatial memory and serum corticosterone levels.

Rats in four groups (10 rats in each group) were randomly exposed to treadmill exercise, immobilization stress, both together or without intervention for four weeks. Assessment of learning and spatial memory Performed using the Morris water maze device. After the last session, direct blood samples were taken from the left ventricle to measure cortisol.

The results showed that in the treadmill training group and also in the stress group, the average distance traveled to reach the platform was higher than the control group (p

The influence of psychological factors in the field of sports performance, prevention of sports injuries, sports rehabilitation and as an effective tool for managing stress and anxiety in competitions has been increasingly approved by various researches. The aim of this study was to determine the competitive trait anxiety of baseball players in the Iranian Premier League and to investigate its relationship with sports injuries in them.

The statistical population of the study included 95 male baseball players participating in the Iranian Baseball Premier League, 79 of whom were tested. The personal information questionnaire, Competitive Sports Anxiety Questionnaire (SCAT) and Sports Injury Questionnaire were used to collect research data. To describe the data, descriptive statistics and indicators of central orientation and frequency distribution tables were used and in inferential statistics, independent t-test was used.

The results showed that 58.9% of the injured players had low anxiety, 41.1% of them had moderate competitive anxiety and none of them had high competitive anxiety. On the other hand, all uninjured players (100%) had low competitive anxiety.

The results showed a significant difference between the mean scores of competitive sports anxiety of injured and uninjured baseball players. Therefore, it seems that competitive sports anxiety has a significant relationship with sports injuries in Iranian Premier League baseball players.

The present study aimed at investigating the relationship between exercise addiction and sport commitment of athletes and closure of sports venues and events due to corona virus (Covid-19).

The current study was a descriptive correlational one. The participants of the study consisted of 134 elite athletes (64 men) who had at least 5 years of sports experience at the level of the super league and national with an average age of 20.87 (15 to 35 years). To measure Sport Commitment, Sport Commitment Questionnaire of Scanlan et al. has been applied, and Terry et al.’s exercise addiction checklist has been used to measure the exercise addiction. The collected data has been analyzed by means of Spearman's correlation coefficient and regression.

The results of the study revealed a significant positive relationship between sport commitment and components of sport commitment and enjoyment, social constraints and personal investment with exercise addiction. In addition, sport commitment and its components explain 29% of the variability of exercise addiction scores. Besides, personal investment significantly predicted exercise addiction (p < 0.05).

According to the findings, during due to Covid-19, with decreasing sport commitment, exercise addiction of athletes will be increased. Moreover, personal investment was also a good predictor of exercise addiction.

The present study aimed at investigating the relationship between mental toughness and self-confidence resources of elite male and female athletes in individual and team discipline.

The current study was a descriptive – correlational one. The participants of the study were the total number of individual and team athletes in Tehran province who had at least 5 years of sports experience, and participated in national competitions no less than one time. For this reason, the statistical sample was 145 elite athletes (15 to 40 years old) with average age of (26/84 ± 5/755) in different sport disciplines using available sampling (62 males, 83 females). To measure mental toughness and its component Sport Mental Toughness Questionnaire (SMTQ) of Sheard, Golby et al. has been applied, and Vealey’s Sources of Sport-Confidence Questionnaire (SSCQ) has been used to measure the sources of sport confidence. The collected data has been analyzed by means of Spearman's ranking correlation coefficient.

The results of the study revealed a positive and significant relationship between mental toughness and all three components of sources of sport confidence (p

The purpose of this study is to determine and compare the effect of traditional and Montessori methods on perceptual motor activities of elementary school students. This research is applied in terms of purpose and semi-experimental in terms of implementation. Abad forms. The sample size in this study was selected using G-POWER software and the sample size was 36 people. It is necessary that three groups of 12 people are selected randomly from them.

In this study, there are three groups of 12 people for research, one of which is the Montessori training program; In the second group, the traditional training program and the third group as a research control group, in which the two experimental groups performed the necessary training sessions for 8 weeks and 3 sessions per week.

In both traditional and Montessori groups, the changes in pre-test and post-test are significant and this means that both Montessori and traditional methods have been able to improve students' balance.

. The results showed that the Montessori group had the greatest impact on fine motor skills. Also, the traditional training group was able to create a significant difference with the control group

The aim of this study was to investigate the effect of Short term use Sodium Bicarbonate (BS) on anaerobic performance and lactate response of healthy trained men.

In a semi-experimental study, 10 healthy trained men after attending in the first session to measure anthropometry characteristics, rest lactate level and basic anaerobic performance, participated in one sessions of placebo (A solution containing 2% dextrose) and then one sessions of BS supplement (0.3 gr per kg of body weight. Placebo or BS was taken 60 minute before intervention sessions. blood samples were taken 1 hour before 1st session and 5 minutes after the 2nd and 3rd sessions. Average and maximal anaerobic performance were measured by rast test. At the end, data were analyzed by repeated measure test as well as the follow-up Bonfroni test, at a significance level of 0/05.

Results showed that acute BS supplementation compared to placebo, significantly reduced lactate response to exercise (ϼ˂0/008) and increased average anaerobic power (ϼ˂0/006). nevertheless, acute BS supplementation compared to placebo, didn't have a significant effect on maximal anaerobic power (ϼ=0/32).

We find that acute SB supplementation can reduce lactate response to exercise and increase average anaerobic, but doesn’t seem to have a significant effect on maximal anaerobic power.

The aim of this study was to determine the effect of treatment-based summoning of thoughts and assumptions on reducing the cognitive distortions of female students.

The research method is semi-experimental with pretest and post-test design with unequal control group, The statistical population of the study included all female students in all levels of Islamic Azad University of Hamedan, who in the academic year 94-93, 1636 people. Non-random sampling method was used for voluntary selection. In this way, among those who duly filled out the questionnaire, The 30 subjects who showed the highest score in cognitive distortion were selected and then randomly assigned to two experimental and control groups. Cognitive therapy based on the call of thoughts and assumptions was grouped in 9 sessions and each session was given for 1 hour and a half for the experimental group and the control group did not receive any treatment. The instrument for measuring data was the Cognitive Distortion Questionnaire (Albert Ellis).

The results of covariance analysis indicated that the intervention was effective and resulted in improved Cognitive distortion in the experimental group (p <0.05). Considering the effectiveness of cognitive therapy by relying on the call of thoughts and assumptions in reducing the Cognitive distortion of female students in the experimental group compared with the control group, the use of this method is recommended for the improvement of Cognitive distortion.

The results of this study showed that cognitive therapy is based on the training of recall of thoughts and assumptions by reducing cognitive distortions of students.

This study was conducted to scrutiny the effect of eight weeks perceptual-motor exercising on static balance of Taekwondo players of Kermanshah.

In this study, 80 children aged 6 to 8 years old were randomly selected from the city of Kermanshah and the effect of perceptual - motor as independent variables on children's balance were assessed. Balance with the force plate were measured. Subjects were randomly divided into four groups; two control groups, two active groups and equal number of gender in each group. First of all, subjects were tested by pre-test, then the 40 subjects in the experimental group were performed perceptual-motor exercises Which consists of three section; warm-up and stretching exercises, specific movements of perceptual-motor and combination and professional Perceptual-motor activities eight weeks; three times a week while 40 subjects in the control group do their usual activities in this eight weeks. Then the post-test was conducted. To determine the difference between pre-test and post-test analysis of covariance with factorial design was used (P <0/05).

The results showed that perceptual-motor exercises were effective to improve the static balance of male and female Taekwondo player. The impact of the training on the static balance of males and females did not show significant difference.

According to the results of this study, it can be recommended that perceptual-motor exercises and activities be executed in the schools for children. In addition, The results can be used by educators to be applied in sports.

The aim of this study was to investigate the effect of movement literacy games on the academic achievement of children with learning disabilities. The present study was a quasi-experimental with a posttest with a control group. This research was based on the purpose of applied research. The statistical population of this study consisted of students with learning disabilities in the primary school of Semnan province (Semnan city) in 1998-99, who were studying in special schools. The statistical sample consisted of 20 children who scored similar scores on the K-Mat test. Sampling was performed available. Samples were randomly divided into two groups, which included an experimental group (which performed movement literacy games) and a control group (which had no training). To measure academic achievement, Iran K Matt Mathematics Test (academic achievement measurement) was used. According to the pre-test score, the children were homogenized in two groups. The first group did a selection of exercises from the Motion Literacy Games program to develop motor skills, including sports, play, and active reactions for children. The second group only dealt with daily activities. These programs were implemented in 8 weeks, which include 2 sessions per week and a total of 16 sessions. Each session lasted 45 minutes, with games of motor literacy (taken from the book physical Literacy on the Move). The results showed that the experimental group was better in the academic achievement discussion than the control group in comparing post-test scores.

The aim of this study was to investigate the effect of 8 weeks of group-based training on gross motor skills and motivation for sports participation in children with developmental coordination disorder aged 10-8 years.

30 children with developmental coordination disorder were randomly divided into control and experimental groups and the experimental group participated in group-based exercise and play for 8 weeks. Before and after 8 weeks, both groups of tidal motor growth test, which has two subscales of displacement and object control, and a sports participation motivation questionnaire were taken.

The results of t-test of difference scores showed that exercise and group-based play had a significant effect on both subscales of gross motor development and motivation for sports participation in children with developmental coordination disorder.

It seems that the emphasis on group-centered exercise and play in children with developmental coordination disorders can improve their gross motor skills and increase their motivation to participate in sports.
