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).

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.

Prevalence of coronavirus (COVID-19) have led to an increase of 156 million confirmed cases and more than 3255,000 deaths worldwide by March 2021. The current disruption of coronavirus COVID-19 exercise has challenged physicians, coaches, and assistant coaches to identify the best ways to return safely to exercise. There is a specific need to create and take ongoing measures to resume sports activities, including training and competitions, to prioritize the health and well-being of athletes while protecting coaches, staff and spectators. This article provides an overview of the effects of coronavirus COVID-19 on the sports population and provides considerations for exercise during an outbreak, as well as guidelines for returning to exercise with restrictions. staff and spectators.

The purpose of this study was to orient shopping habits: a model for consumers of Iranian sports goods.

The present study is descriptive-correlative in terms of applied purpose. The statistical population of the study was all managers and experts of sports production companies and sports stores that the statistical sample was selected as available. A researcher-made questionnaire was used to collect data and the face validity of the questionnaire was confirmed by experts (13 people). Its reliability was also calculated using Cronbach's alpha test (0.92) and combined reliability. Structural equation modeling in PLS3-SPSS24 software has been used to analyze the data and evaluate the model fit.

The results showed that except for the effect of environment on shopping habit which was not confirmed (P> 0.05), all coefficients of significance t are greater than 1.96, which means that all questions and relationships between variables are significant at the level. 95% Confirmation.

In general, according to the results of the research, it can be said that in order to institutionalize the habit of buying domestic sports goods, the factors used in this research should be considered as a model for their decision making.

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).

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 purpose of this study is to investigate the effect of strategic intelligence on macro-environmental intelligence, organizational resources intelligence, competitiveness intelligence, organizational processes intelligence of the Ministry of Sports and Youth. The research method of this dissertation is a sequential exploratory mix, the number of samples used in the Delphi stage for this research is 12 and the sampling method is chain or snowball. In the quantitative part of the present study, the statistical population includes 705 managers and staff of the Ministry of Sports and Youth. The questionnaire, which was obtained after the Delphi stage and with the opinion of experts, contains 133 items. This tool was validated by exploratory factor analysis. Exploratory factor analysis with SPSS software (measurement model test based on the validity and reliability of measurement tools) and with Smart PALS software confirmatory factor analysis (Structural model testing, test Hypotheses and the study of the effect of variables on each other) were performed. Strategic intelligence in the Ministry of Sports and Youth consists of different types of intelligence that create a synergy and interaction between macro-environmental intelligence, organizational resource intelligence, competitive intelligence, organizational process intelligence rather than information and knowledge. Provide added value for the organization to make strategic decisions.
