Introduction and goal:

The purpose of this study was to compare two types of traditional resistance training and crossfit resistance training on Fat free mass index and fat mass index of overweight and obese women.

This semi-experimental study, with pre-test and post-test, included 30 women with overweight and obesity with a mean age of 27 ± 2 years who were divided into two groups by purposeful sampling.

  After analyzing the data and statistical tests of the research hypotheses, the results showed that the effect of the protocol of crossfit resistance training  versus the traditional resistance training protocol on the Fat free mass index of adult women with overweight and obese was not significant (P ≤ 0.31 ) The effect of the crossfit resistance training protocol on traditional resistace training protocols on fat mass index of overweight and obese women was significant (P ≤ 0.01).
Discussion and

According to the present study, it can be concluded that crossfit exercises have a significant difference in the reduction of fat mass index compared to traditional resistance exercises.

Overweight and obesity are among the most important public health concerns associated with multiple negative health outcomes. Physical activity is an important lifestyle behavior that helps to regulate body weight. ALSO, Physical activity reduce the risk of diabetes, cardiovascular disease and cancer, middle-aged men and women are now recommended to maintain a healthy body weight, avoid overweight and obesity, and maintain a good serum lipid profile. In addition, studies have shown the effect of orange juice consumption on improving lipid profile and metabolic syndrome index. The aim of the present study was to investigate the effect of 8 weeks of aerobic training combined with orange juice consumption on the concentration of liver enzymes and fasting blood sugar in overweight middle-aged women (30-59 years).

This study was performed as a voluntary clinical trial on 60 overweight women (BMI≥ 28) age between 30 and 59 years from the Kan Health Center. Randomly divided into 4 groups (n = 15) (exercise) (exercise + orange juice) (orange juice) and (control) respectively. At the beginning and the end of the study, blood samples were taken after 12 hours fasting. Supplementation and Exercise The day after blood sampling, the supplemented groups received 500 ml of orange juice daily for 8 weeks and three with weekly, the control group did not participate in any training program. The endurance training protocol was performed on treadmill running and walking for eight weeks and three sessions per week with intensity of 45 to 98% of maximum heart rate. Training sessions lasted from 28 to 38 minutes and were warmed and cooled for 18 and 7 minutes, respectively, before and after each training session. All data were entered into SPSS version 24 for statistical analysis.

The results of this study showed that eight weeks of aerobic training with orange juice had no significant effect on the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and fasting blood sugar in overweight middle-aged women. But eight weeks of aerobic training alone and consumption of orange juice alone significantly decreased serum alkaline phosphatase (ALP) levels in overweight middle-aged women (p <0.05).

The results of this study showed that eight weeks of aerobic training with or without orange juice intake had no significant effect on fasting blood glucose and liver enzymes except ALP.

The purpose of this study was to identify the factors affecting the survival and prolongation of national championship athletes' lives. The purpose of this study is applied research and data search is a combination of exploratory data analysis and field data collection. The statistical population of the qualitative section includes all experts of selected sport federations of the country and the statistical population includes all the officials, experts and coaches of the national swimming federation, athletics and gymnastics and national team athletes. The data collection tool in the qualitative part of the in-depth interview with experts and in the quantitative part was a 72-item researcher-made questionnaire from the qualitative part. Descriptive and inferential statistics were used for data analysis by SPSS software version 21 and LISEREL version 8.8. The findings of the present study showed that the questionnaire of validity and reliability of factors affecting the longevity of national team athletes' championships in international and Olympic competitions.

In recent decades, human life has been heavily influenced by new communication, while virtual social networks as a part of these new media and communications have provided users with the benefits of خn the one hand, they share their interests, thoughts and activities without time and space; on the other hand, these networks can be effective in all fields. The purpose of this study was to investigate the effect of using virtual social networks with the role of mediating quality of life on general health of veterans and disabled athletes in Iran.

In this research, descriptive and correlational method was applied field-based and using a questionnaire. The statistical population of this study, all veterans and disabled athletes in Iran, according to the latest statistics received from the head of the provincial affairs office of the Federation of Veterans and Disabled Sports in 1396, numbered 18,229 athletes, 13653 men and 4576 women. The method of sampling in this research was multi-stage cluster random sampling. And the sample size according to the Morgan table, 384 veterans and disabled athletes, and a total of 480 distributed questionnaires in eight provinces (Tehran-Mazandaran-South Khorasan-Khuzestan-Kermanshah-Central-Hormozgan-West Azarbaijan), each of which 60 questionnaires, 40 There were 390 questionnaires, geographic area and the most number of athletes. Descriptive statistics, frequency distribution tables, frequency, percentage and standard deviation were used to organize, summarize, categorize raw scores and describe the data. To analyze the data (comparing the meanings), one-sample t-test was used to prioritize the variables by Friedman test, and for statistical relationships, Pearson correlation coefficient and for predicting variables, the linear regression coefficient and for testing the operational model from the structural equations SPSS version 22 was used at the significance level of 0.05

The results showed that there is not a meaningful relationship between virtual social networks and quality of life with general health, but there is a significant relationship between quality of life with general health as well as between quality of life components and general health (0.001 ≥ P).

It seems that quality of life and all its components can be directly related to general health and all its components, regardless of the amount of use of social networks. In this study, according to the results of the study, considering that most of the physical and psychological effects of the process are gradual and sometimes they are marked and recognizable for decades, and the spread of virtual social networks is less than two It is not decisive that the role of these networks can not be ruled out or confirmed in the formation of such social damages, and the consistency or inconsistency of the research is mentioned, so further research should be done.
