The prevalence of psychological problems in the elderly with mild Alzheimer's is high, which requires interventions to solve these problems. This research was conducted with the aim of determining the effectiveness of repetitive transcranial magnetic stimulation (rTMS) treatment on executive function and working memory of elderly people with mild Alzheimer's disease.

The research method was semi-experimental and pre-test, post-test with a control group. The statistical population included all elderly people with mild Alzheimer's disease in Kerman city in 2023, 30 people (15 people from the experimental group and 15 people from the control group) were selected by available sampling method. The data collection tool was the executive function questionnaires of Gerrard et al. (2000) and the working memory questionnaire of Enbeck (1985). The treatment intervention of repeated transcranial magnetic stimulation in 10 sessions of 20 to 30 minutes and twice a week was performed on the experimental group and the control group did not receive any intervention. Data analysis was done with descriptive tests (mean and standard deviation) and covariance analysis using SPSS version 24 software. The level of P less than 0.05 was considered significant.

in the executive function variable, the mean and standard deviation of the experimental group in the pre-test was 146.92±16.74 and in the post-test 192.82±16.37 and in the working memory variable, the mean and standard deviation of the experimental group in the pre-test 36.19 ± 7.40 in the test and 68.59 ± 6.43 in the post-test. The results of covariance analysis also showed that repeated transcranial magnetic stimulation treatment had an effect on the executive function and working memory of the elderly with mild Alzheimer's disease (P < 0.01).

Based on the research findings, the treatment of repeated transcranial magnetic stimulation can be used to increase the active memory of the elderly with mild Alzheimer's.

Changing the lifestyle towards inactivity and low physical activity increases the risk of metabolic and cardiovascular diseases. The purpose of this research was to determine the effect of physical activity on some cardiovascular risk factors, body mass index and ankle-brachial blood pressure index of middle-aged people of Shahid Rajaei University.

The statistical sample included 81 male and female employees of Shahid Rajaee University of Education, Tehran. The age range of the subjects was between 26 and 58 years. The physical activity of the subjects was measured through a researcher-made questionnaire. Fasting blood sugar and lipid profiles were measured by special test strips. The ankle-brachial blood pressure index of the subjects was also evaluated to evaluate peripheral artery disease. Data analysis was done using one-sample t, independent t and Pearson correlation test at a significance level of 0.05.

Statistical analysis showed that blood sugar, blood lipid profile, brachial ankle index, and body mass index of university employees were within the normal range, except for the triglyceride level, which was in the borderline risk range. In all research variables, no significant difference was observed between university employees and professors (P 0.05). There is a significant negative correlation between cardiovascular risk factors (total cholesterol levels, blood triglyceride, LDL-C) and ankle-brachial blood pressure index with the subjects' physical activity level (P0.05).

Based on the findings of this research, it can be said that as the amount of physical activity increases in both groups of middle-aged university professors and staff, the amount of measured cardiovascular risk factors and ankle-brachial blood pressure index decreases and vice versa. . Therefore, middle-aged people can be advised to do regular and daily light physical activity such as walking in order to improve cardiovascular risk factors and lower limb artery disease.

The current study aims to explain a communication model for quantum leadership, productivity and empowerment of personnel in the Ministry of Sport and Youth using Interpretive-Structural Modeling approach. The research population included all of the personnel in the Ministry of Sport and Youth, and 269 persons were selected randomly as the research sample. The research tool was questionnaires adopted from the literature for collecting the research data. Twelve sport management experts and Cronbach’s alpha method, respectively confirmed the validity and reliability of the questionnaires. SPSS software and interpretive-structural modeling (ISM) approach were applied to analyze the research data. The results indicated the optimal level in the quantum leadership, as well as personnel productivity, and empowerment. Based on the results, an increase in the level of quantum leadership in the Ministry of Sport and Youth raises the level of personnel productivity, and empowerment. In addition, an increase in the personnel empowerment level in the Ministry of Sport and Youth increases the level of personnel productivity.

Overweight and obese people who do not engage in physical activity or exercise are usually at risk for certain metabolic, cardiovascular, and type 2 diseases, such as type 2 diabetes, coronary artery disease, and hypertension. The aim of this study was to investigate the effect of eight weeks of concurrent training (resistance and endurance) on insulin resistance and plasma levels of resistin and glucose in overweight and obese middle-aged men in Yasuj.

The research method was quasi-experimental with pre-test and post-test design.  The statistical population was overweight and obese men aged 30 to 45 years in Yasuj. The sampling method was purposeful and 30 people were selected as a statistical sample and were randomly divided into two groups of  concurrent training and control. The subjects in the experimental group performed 8 weeks of  concurrent training and 3 sessions per week. Data on insulin resistance,  plasma resistin and glucose before and after concurrent training were analyzed using Kolmogorov-Smirnov, dependent and independent t-tests at a significant level of p<0.05.

The results showed that insulin resistance, resistin and plasma glucose levels in the post-test in the experimental group were significantly reduced compared to the control group (p <0.05). In contrast, no significant change was observed in all variables in the control group (p > 0.05).

Therefore, it is can to suggest 8 weeks of concurrent resistance and endurance training that were performed in one session as one of the preventive and non-pharmacological methods to improve the metabolic, cardiovascular health status of overweight and obese middle-aged men.

The purpose of this study was to investigate the study of shooting accuracy and fatigue of leg muscles after eight weeks of resistance training in shooters men with a Inflatable pistol.

The statistical population of elite male shooters was Kohgiluyeh and Boyerahmad provinces. The sample consisted of 20 subjects who were randomly divided into two groups. The data were analyzed using repeated  measures ANOVA and Pearson correlation coefficient tests. The resistance training protocol included the five movements that were performed slowly and in the morning. The movements were performed in 3 sets of 10 repetitions in the first session and in the final session with 5 sets, 14 repetitions. The duration of the resistance training sessions was 8 weeks, 3 sessions each week. The method of data analysis was determined based on research hypotheses, number of status forms (2 forms), and variables of research and performed SPSS software version 20 was used.

Results showed that following eight weeks of resistance training, the accuracy of targeting and muscle fatigue in the post-test were compared with the pretest in the groups were significantly different (P=0.05). There was a high correlation between changes in muscle fatigue and target accuracy in both standing and stand-up positions (P=0.05).

In general, the results show that changes in muscle fatigue and target accuracy in two form of standing positions after 8 weeks of resistance training were positive.

Current changing lifestyles of Iranians, especially in childhood, may affect the risk of developing cardiovascular diseases.
The purpose of this study was to determine the effects of endurance, resistance, and combined training on cardiovascular risk factors in male obese children.
Sixty male obese children (age 8 - 12 years, BMI between 30 - 35 kg and Z-score above ) were chosen randomly divided into four groups of exercise training: group I, endurance exercise training (EET); group II, resistance exercise training (RET); group III, combined exercise training (CET); group IV, controls (C). Exercise training programs were performed for eight weeks, 4 sessions per week, with the same intensity and duration in all types of exercise training groups. Blood samples were collected 24 and 48 hours before and after exercise training, respectively. Data were obtained in all groups and analyzed by repeated measurement and one way ANOVA using SPSS software (version 21).
Results indicated that fasting glucose, BMI, TC, TG, LDL, VLDL, TC/HDL, and LDL/HDL ratio decreased significantly and HDL increased in three types of exercise training compared to the control group (P 0.05).
The three types of exercise training, especially endurance training method, decrease the risk factors for occurrence of cardiovascular diseases and health complications related to obesity in inactive male obese children.
