Today, the most important issue in sports and motor success, especially for children, is improving their motivation. Therefore, the aim of this study was to compare challenging and non-challenging games of children's motor motivation.

The present study was a quasi-experimental study with a pre-test-post-test design. The participants in this study were 40 children (mean age 6.15 and standard deviation 1.12) who were selected by the available method. Participants were randomly divided into two groups of challenging games (20 people) and non-challenging games (20 people). They then received motor skills interventions for eight weeks, two sessions per week, and each session lasting 90 minutes. Data were analyzed by analysis of covariance.

The results showed that the effect of exercise for motivation in groups was significant so that the rate of changes in motor motivation from pre-test to post-test in the challenge group was more than the non-challenge group. Therefore, the effect of challenging training on motivation is more than non-challenging training.

The results of this study emphasize the use of playful form of interventions in childhood and in the design of interventions, use of manipulation of constraints and its challenge to motivate children is helpful.

The aim of this study was to investigate the barriers to participation in girls' physical activities and its relationship with academic motivation and depression.

The statistical population of this study was 180 13-16 years old female students in Rivash city of Khorasan province. The instruments used in this study were the questionnaire on barriers to student participation in sports activities, the Harter questionnaire to determine the level of academic motivation and the Beck questionnaire to determine girls' depression.

The results showed that in terms of priority, barriers to participation in physical activity (economic, cultural, physical and psychological), cultural barriers with (73.3) and economic barriers with (70.2%), the most, psychological barriers with (30.2) and physical barriers with (27.1) percent, have the lowest priority to participate in physical activity. The results of Spearman test showed that there is no significant relationship between economic and cultural barriers with girls' educational motivation, but there is a significant negative relationship between physical and psychological barriers with academic motivation. The results also showed that there is no significant relationship between economic barriers and depression in girls, but there is a positive and significant relationship between cultural, physical and psychological barriers with depression in adolescent girls.

Female students face many difficulties in participating in sports activities that they are interested in doing. If the necessary measures are taken to provide more and better use of sports and recreational facilities for adolescent girls, it is possible to reduce depression and increase their academic motivation.

The aim of this study was to evaluate the effect of combination exercises (aerobic-resistance) on coupeptin and insulin resistance in obese women with polycystic ovary syndrome. In this quasi-experimental study, which was performed with a pre-test-post-test design, 28 obese women with polycystic ovary syndrome ranging in age from 20 to 35 years were randomly selected and divided into 2 groups of 15 combined and control exercises. Blood samples were collected in two stages of pre-test and post-test (after 8 weeks of training). The training protocol consisted of 2 weeks of combined exercises that were performed three sessions per week in two sections of rope training and resistance training with elastic. Data were analyzed by analysis of variance with repeated measures. The results showed that combined exercise significantly increased the coupeptine of obese women with polycystic ovary syndrome (P <0.05). Other results also showed that combined exercise significantly reduced insulin resistance in obese women with polycystic ovary syndrome (P <0.05). Overall, the present results suggest that obese women with polycystic ovary syndrome may be able to prevent the inflammatory stress caused by exercise and its aftermath by using combined exercise.

Sports clubs, like other legal entities, have rights and obligations, and failure to do so, whether contractual or legal, may result in civil or disciplinary liability for the clubs, as the case may be. The legal relationship of sports clubs with the relevant athletes and coaches is based on the labor-employer relationship and is subject to the labor law, except in special cases such as the bylaws and sections of the relevant federations. Clubs have a liability on behalf of third parties, including athletes and spectators, to the damages incurred by the relevant athletes and coaches. The basis of civil liability of sports clubs in the Iranian legal system is based on the presumption of fault. The most important duty of sports clubs is to comply with the safety obligations of the club, the non-observance of which leads to civil or disciplinary liability of the relevant club.Therefore, the liability of sports institutions for damages resulting from their activities is subject to Article 12 of the Civil Liability Law and of the type of proxy liability.

Life satisfaction is a reflection of the balance between a person's desires and her current situation, and the greater the gap between the level of a person's desires and her objective situation, the lower her satisfaction. The aim of this study was to predict the life satisfaction of bodybuilding athletes based on the trait of anxiety and emotional regulation mediated by happiness.

The statistical population of this study includes 200 athlete (bodybuilder) subjects who were randomly selected from sports clubs and among them four questionnaires of quality of life, stress-anxiety, emotional cognitive regulation and happiness were distributed. Data obtained from these questionnaires were analyzed by Pearson correlation test and SPSS software version 24.

The relationship between life satisfaction and re-evaluation ,emotional , and also with inner happiness and final happiness at the level (α = 0.01) .Also, the subscale of re-evaluation of the regulation scale with internal happiness (0.288) and final happiness - (0.288) also had a positive and weak relationship at a significant level (α = 0.01).

Based on the results, it can be concluded that the psychological variables of emotional regulation, temperament and state of anxiety and happiness of athletes play an important role in their life satisfaction and according to the direct and positive relationship, happiness can be a variable. An effective and important mediator in improving the life satisfaction of athletes (bodybuilders).

This study was performed to investigate the correlation between the repetitive activity test (RSA) and the 30 second Wingate test in measuring the anaerobic capacity of wrestlers and the possibility of their replacement.

The subjects included 20 wrestlers of Kharazmi University (height 174.13 ± 5.5 cm, weight 77.05 48 5.48 kg, age 25.43 6 6.11 years, body fat 10.39 3 3.11% and BMI / 63). For this purpose, the maximum, minimum and average power and fatigue index of performing the Wingate test and the ability to repeat the activity of speed (walking a distance of 20 meters with 20-second rest intervals in 12 turns) were calculated and the amount of lactate and blood was measured later. It was measured 2 minutes after performing both tests. Pearson correlation coefficient was used to evaluate the correlation between power indices and physiological indices (blood lactate). 

The results showed that there was a significant correlation between the maximum, mean and minimum power obtained from the Rapid Repeat Activity (RSA) test and the Wingate test (r = 0.81p = 0.002, r = 0.78p = 0.003, r = 0.83p = 0.001) but there was no correlation between the fatigue index of the two tests (r = 0.013, p = 0.746). /15 and 13.8 mmol / l) no difference was observed (p = 0.382).
