        1 - Analysis of Crypto Market Transaction Tracking
        Ali  Yousef Yahya  Ahmad

        Despite being completely unknown for more than a decade, cryptocurrencies are now a trillion dollar worldwide industry with more than 4,000 different currencies available. Additionally, the decentralized nature of digital currencies has elevated the sector to a level where privacy and safe transactions are taken for granted. Market analysis, however, indicates that there are numerous security flaws that could jeopardize the genuine anonymity of the bitcoin transaction network. In this post, we examine a few network security flaws that affect cryptocurrency systems. Manuscript profile

        the purpose of this research was the effect of physical fitness exercises on dynamic balance and static balance in hearing impaired girls aged 13 to 15 years with vestibular system dysfunction in Mashhad. The research method was semi-experimental with a pre-test and post-test design with a control group. The statistical population of this research included all hearing-impaired girls with bilateral vestibular problems aged 13 to 15 in Mashhad. The statistical sample was selected in a targeted manner and randomly selected in two experimental and control groups (12 people in each group). The experimental group participated in a physical fitness program for 8 weeks, 3 sessions per week and 60 minutes per session. The control group only did daily and normal activities. Balance tests were taken from the participants before and after the training period. The statistical method of independent t-test was used using spss21 software to compare between two groups. The results showed that physical fitness exercises increased both static balance and dynamic balance in 13 to 15-year-old hearing-impaired girls with vestibular dysfunction (P<0.05). This indicates that hearing impaired children can improve their balance by participating in a physical fitness training program that includes 8 weeks and 3 sessions per week for 60 minutes.

        the purpose of this research was to compare personal, social, and sports identity in deaf sportsmen and non- athletes in Mashhad. The research was done based on the analytical descriptive method. The statistical population included deaf women who were members of the Mashhad Center for the Deaf and were residents of Mashhad. Based on the simple random sampling method and using the Krejcie and Morgan table, 359 people (952 deaf athletes and 247 deaf non-athletes) were selected as a statistical sample. Standard questionnaires of sports identity (Borour, 1993), social identity (Safariniya, 2011) and personal identity (Adamz, 1986) were used to collect data. The reliability of the tool was calculated using Cronbach's alpha and was 0.83, 0.74 and 0.81 respectively. Independent t-tests and one-sample t-tests were used to analyze the data. There was a significant difference between deaf athletes and non-athletes based on individual identity, sports identity and social identity (P<0.05). Individual identity was at a suitable level in deaf female athletes, but not at a suitable level in deaf non-athlete women (P<0.05). Sports identity was at a suitable level in deaf sportswomen, but not at a suitable level in deaf non-athletes (P<0.05). Social identity was at an appropriate level in deaf sportswomen, but not at an appropriate level in deaf non-athletes (P<0.05). It seems that engaging in sports in deaf women improves their individual identity, social identity and sports identity. Manuscript profile

        4 - The Effect of Simple Pyramid Resistance Training Session with Branched-Chain Amino Acid Supplementation on Insulin- Like Growth Hormone-1 Levels in Postmenopausal Women

        the aim of the current research was the effect of a simple pyramid resistance training session with BCAA supplementation on IGF-1 levels during different periods of time in postmenopausal women. The current research was semi-experimental and applied. A total of 19 inactive postmenopausal women were selected. At first, the subjects were given the necessary information about the objectives and method of conducting the research, and each subject completed the consent form, physical activity and medical-sports readiness questionnaire. Then the subjects were randomly divided into two groups of simple + supplement pyramid resistance training (10 people) (age 52.20 ± 5.70 years, height 1.57 ± 0.01 cm and weight 88.76 ± 14.81 kg), Simple pyramid resistance training group + placebo (9 people) (age 50.89±4.25 years, height 1.60±0.01 cm and average weight 88.76±7.41 kg) were divided. The resistance training program was a pyramid with an intensity of 70-80% of one repetition maximum. The simple pyramid resistance training group + supplement consumed 0.1 gram per kilogram of body weight of BCAA powder in solution. Serum IGF-1 levels were measured before, 30 and 120 minutes after exercise. Two-way repeated measures statistical test was used to analyze the data. The findings showed that a simple pyramid resistance training session with BCAA supplementation has no effect on IGF-1 serum levels at different training times of postmenopausal women. Also, the difference between the groups in the level of IGF-1 after exercise was not significant. Probably, a simple pyramid resistance training session with and without BCAA supplementation at the rate of 0.1 gram per kilogram of body weight before and after training has no effect on the initial increase of IGF-1.

        5 - The Effect of Two Types of Recovery Activities in Cold Water and Massage on Creatine Kinase (CK) and C-Reactive Protein (CRP) in Football Players

        the purpose of this study was to compare the effect of two types of recovery (massage and running in cold water) on creatine kinase (CK) and C-reactive protein (CRP) of soccer players following a simulated soccer activity. 14 youth male soccer players were purposefully selected and randomly placed in two groups of recovery of massage and recovery of running in cold water (7 people in each group). On the day of the sports test, at 10:00 AM, all the subjects participated in a simulated soccer physical activity session with the difference that the massage group recovered by massage after the activity; And the cold water running group recovered after the activity by running in cold water. Immediately after the activity, after recovery, 24 hours later and 48 hours after the activity, blood samples were taken from all subjects. The serum levels of CK and CRP first increased and then began to decrease, and these changes were significant (P<0.05), but the difference between the two groups was not significant (P>0.05). Probably, recovery in water or in the form of massage leads to the reduction of inflammation in young football players after a simulated football activity, but there is no difference between the two types of recovery.

        the aim of this study was to investigate the effect of nonlinear resistance training with dill extract on adropine and its relationship with insulin resistance in type 2 diabetic patients. 32 patients with type 2 diabetes were divided into four groups: resistance training, supplementation, resistance training + supplementation, and placebo. Interventions were performed for 12 weeks. Consumption of dill included 300 mg / kg body weight per day. Nonlinear resistance training, consumption and their combination significantly reduced blood sugar and insulin resistance and significantly increased adropine levels (P <0.05). These changes were significantly greater in the exercise and dill combination groups. The relationship between adropine changes and insulin resistance was also significant and negative (P <0.05). Adropine may play a role in reducing insulin resistance following nonlinear resistance training. Consumption can increase the effects of exercise. Manuscript profile
