Background: Sports Investments is one of the most unique sports events, in the country dealing both with collectors and dealers. Aim : The purpose of this study was to compare the sports investment o Iran in 2016 and 1998. Therefore, we estimate the value of the sports investment sector and share of total investment, GDP, GDSP and compare with 1998 in Iran. Materials and Methods: In this study, national accounts were used. Most of the basic data fare available in a decentralized manner in the Statistics Center and the Program and Budget Organization of Iran. Due to achieving real changes in sports investment between 1998 and 2016, prices in 1998 was considered as the base year and were considered. Then using the price index of the desired years, the effects of inflation were eliminated and growth real was calculated. Results: The results indicate that investment in sport in 1998 was 360 billion Rials, which is 0.43% of total investment, 0.1% GDP, and 26.2% of GDSP. Also, investment in sport in 2016 was 15449 billion Rials, which is 0.46% of total investment, 0.11% GDP and, 73.38% of GDSP. Investment in sport in 2016 compared to 1998 had 2347% real growth. Conclusion : Although, investment in sport in 2016 compared to 1998 has grown, but it is very small compared to the total investments. Results also show the major share of the public sector and the low participation of the private sector.

Purpose: This study was conducted aiming to investigate the effect of selected TRX and Pilates training on balance parameters, fatigue index, and quality of life in female patients of multiple sclerosis. Method: In this study, 30 female patients with MS in Isfahan city with an average age of 37.41 ± 7.57 years and a history of MS of 11.31 ± 3.77 years and an Expanded Disability Status Scale of 0.84 ± 1.81 were placed in three groups including control, TRX and Pilates groups. The training program consisted of eight weeks including 3 sessions of 60 minutes of exercise per week. In order to investigate balance, fatigue, and quality of life, the Berg test, Fatigue Severity Scale, and Multiple Sclerosis Quality of Life were used respectively. SPSS version 25 software was used for statistical analysis. Results: The results of this study have shown that both exercise programs have led to a significant improvement in the mean parameters of balance (P < 0.005), fatigue (P < 0.005), and quality of life (P < 0.001). Conclusions: Considering the noticeable impact of these training protocols on the quality of life, balance and fatigue, these interventions can be considered as an efficient and cost-effective methods to improve health condition in MS patients.

The outbreak of war in Ukraine at the same time as the Beijing 2022 Winter Olympics once again called the world sports to engage in international military warfare. The aim of the present study was to investigate the role of sports deterrent in the prevention of international military wars. The present study was a qualitative-netnogeraphy method, which was conducted by studying various websites and social networks such as Instagram and official websites of BBC sport, CNN sport, ABC sport, Varzesh TV, Olympics and FIFA World Cup pages. The results indicated that sport sanctions of Russia categorized to personal (8) and organizational (21) concepts. Although Sports is a non-political phenomenon, it can play as a peace-making factor to decrease the political and military pressure on nations. Today, athletes, because of their billion audience on social media and messengers, have an irreplaceable impact on the public, including efforts to curb violence, aggression and incitement to war, including effective sports in promoting international peace.

Purpose: On the other hand, fatigue is one of the most important indicators of aging syndrome. This study aimed to investigate the relationship between the level of physical activity and fatigue in elderly residents of rest homes in Tehran. Method: This was a descriptive correlational study in which 20 rest homes located in Tehran province constituted the study population. By visiting rest homes, the eligible subjects were chosen. Physical activity was measured by the Physical Activity Scale for the Elderly (PASE). The FACIT Fatigue Scale is a short, 13-item, easy to administer tool that measures an individual’s level of fatigue during their usual daily activities over the past week. Nutritional status was evaluated by mini nutritional assessment (MNA). Results: The results of statistical analysis indicated a significant and positive correlation between PASE and FACIT scores (r=0.48, p<0.01) while, there was a significant negative correlation between FACIT score and age (r=-0.23, p<0.01). Also, there was a significant positive correlation between MNA and FACIT (r=0.40, p<0.01). In addition, a significant positive correlation was found between MNA and PASE score (r=0.31, p<0.01). Conclusions: The findings of this study indicate that holding sports classes under the supervision of exercise physiologists is an essential matter to increase health and prevent age-related complications in elderly residents of Tehran rest homes.

Background: Anodal transcranial direct current stimulation (a-tDCS) is a new neuro-modulatory technique.Aim: This study aimed to investigate the effect of a-tDCS on dynamic balance after exhaustion.Material and Methods: Fifteen endurance-trained men voluntarily attended five separate sessions. In the first session, Maximal aerobic speed (MAS) was measured. Then, the participants were randomly assigned to four different conditions: 1. Mental fatigue (MF)+a-tDCS, 2. MF+sham (s-tDCS), 3. a-tDCS, and 4. s-tDCS. In each session, after dynamic balance measurement, the participants were exposed to the conditions and received 20 min of anodal tDCS over the dorsolateral prefrontal cortex (DLPFC). Then, the participants performed a submaximal endurance activity at 70% of MAS until exhaustion. Immediately after exhaustion, dynamic balance was measured again.Results: After exhaustion, the dynamic balance of the right leg under the a-tDCS condition was significantly higher than the MF+s-tDCS (P= 0.008). The dynamic balance significantly decreased from pre- to post-test in MF+s-tDCS and s-tDCS conditions (P= 0.0001). In the left leg, the dynamic balance under the a-tDCS condition was significantly higher than MF+s-tDCS (P= 0.025).Conclusions: Anodal stimulation of the DLPFC could be beneficial for the dynamic balance and may have a protective effect against the negative consequence of exhausting activity on the dynamic balance in endurance-trained men.
