The present study was designed and conducted to provide a model of the role of exercise in students' biological health. The present study is applied in terms of purpose, because the results of this study can be used for healthy biological development of individuals. The present study was a mixed research that was conducted qualitatively and quantitatively. The method of data collection in the present study was field. In the present study, the statistical population in the qualitative section included experts and professors aware of the research topic. Also in the quantitative part of the research, the statistical population included students of universities in Bushehr and Fars provinces, including public universities, Azad, Payame Noor. These students included people who were regularly involved in sports activities. These individuals were divided into several groups based on their activities in sports (public sports, educational sports, professional sports and championship sports) who collaborated with the present study according to their sections. The data collection tool in the present study was a semi-structured interview and a researcher-made questionnaire. Structural equation method was used to analyze the research data. The whole process of data analysis was performed in SPSS and PLS software. The results of the present study showed that participation in public, educational, championship and professional sports improves the status of healthy biological indicators including physical self, creative self, self-coping, self-innuend and self-community. Therefore, paying attention to the development of sports in universities can pave the way for a healthy biological improvement.

The current research was applied in terms of purpose and descriptive-correlation in terms of nature; which has been done in the field. The statistical population included prominent professors in the field of sports management, specializing in the field of sports sociology. According to the available selection, 48 people were identified in this section, and after distributing and collecting the questionnaires, 41 completed questionnaires were collected. The sampling method was available. The research tool included a researcher-made questionnaire in two parts: descriptive characteristics and specialized questions. The final questionnaire was prepared using the Likert method and with five options. Its face and content validity was verified by 12 experts and the reliability of the questionnaire was confirmed by Cronbach's alpha method. In addition, the questionnaire was checked and verified using first and second order confirmatory factor analysis. In the part of data analysis, structural equation modeling method with partial least squares approach and using PLS software was used to comprehensively examine the conceptual model of the research. The results of the research showed that causal factors are effective on the main phenomenon (0.629); The main phenomenon is effective on strategies (0.399); Background conditions affect strategies (0.452); Intervening conditions have an effect on strategies (0.234) and strategies have a positive and significant effect on outcomes (0.691). Therefore, in the way of achieving the social consequences and national pride of ethnic identity, strategies should be created in the way of the formation of the charter of ethnic identity.

The purpose of this study was to identify the indicators of improving ethnic identity through professional sports in Iran. This research had a qualitative approach and the method of data theory (grounded theory) was used as the research method. The method of data collection was the study of theoretical foundations and in-depth and open interviews with 16 prominent professors in the field of sports management specializing in sociology. The sampling method was purposeful in a standard type and continued to the point of theoretical saturation. The validity of this study was reviewed and confirmed by the interviewees and then expert professors. Reliability After calculating the agreement coefficient, 70.3% was determined. For data analysis, continuous comparison method was used during the three stages of open, axial and selective coding. The results showed that attention to causal, contextual and intervention factors can, along with the implementation of strategies, lead to the formation of consequences including social consequences and national pride. In general, in order to achieve social consequences and national pride, strategies should be implemented within the framework of the formation of the Charter of Ethnic Identity.

The present study was designed and conducted to investigate the effect of participation in public sports on students' biological health. The present study was one of the survey researches. The method of data collection in the present study was field. The present study was one of the applied researches. The statistical population included students of Fars province universities including public, free and Payame Noor universities in Fars province. These students include students who are regularly involved in public sports activities. In order to analyze the data of the present study, the structural equation method was used. The results of the present study showed that participation in public sports has a significant effect on students' biological health. To this end, improving participation in public sports leads to a healthy improvement in students' lives

Previous studies have indicated that exercise training improves body composition and cardiovascular disease risk factors. The aim of the present study was to investigate the effect of 12 weeks of aerobic, strength and combined training on body composition, intercellular adhesion molecule‑1 (ICAM‑1), vascular cell adhesion molecule‑1 (VCAM‑1), and C‑reactive protein (CRP) in sedentary middle‑aged men.
Forty‑seven male aged 40–60 years voluntarily participated in this study and were divided in four groups: aerobic (n = 12), strength (n = 12), combined (n = 11), and control (n = 12) groups randomly. Body composition, ICAM‑1, VCAM‑1, and CRP were measured before and after 12 weeks. Data were analyzed using paired t‑test and analysis of variance statistical methods.
There were signifcant differences in body weight between aerobic and strength training (P = 0.004) and aerobic and control groups (P = 0.018), body mass index between combined and strength training (P = 0.004) and combined and control groups (P = 0.001), fat percentage between aerobic training and control group (P = 0.017) and combined training and control groups (P = 0.004), and fnally, fat‑free mass between aerobic and strength training (P = 0.024),aerobic and combined training (P = 0.0001), strength and control groups (P = 0.035), and combined and control groups (P = 0.0001).
The results indicated that 12‑week workout, 20–60 min/session, 3 days a week of moderate intensity exercise improved body composition, ICAM‑1, VCAM‑1, and CRP compared to those who did not participate in any training. However, all three types of exercises had small benefts on body composition, ICAM‑1, VCAM‑1, and CRP in sedentary middle‑aged men, and the importance of combined training required further investigations.

The purpose of this study was to investigate the effect of 12‑week of aerobic training on homocysteine, lipoprotein A and lipid profile levels in sedentary middle‑age men. This was a quasi‑experimental study. Subjects of the tudy were 24 men (age 40-60) who participated is the study oluntarily and were randomly assigned in aerobic (n = 12) and ontrol (n = 12) groups. The subjects participated in progressiveaerobic training on treadmill 3 times a week (20 min/session 60% maximum heart rate) to 60 min (75% maximum heart rate). omocysteine, lipoprotein A, triglyceride (TG), cholesterol, ow‑density lipoprotein (LDL) and high‑density lipoprotein (HDL) ere measured before and after 12‑week. Data were analyzed using aired t‑test and independent t‑test statistical methods. Research findings showed a significant decrease in omocysteine (P = 0.002), lipoprotein A (P = 0.003), TG (P = 0.008), holesterol (P = 0.024) and LDL (P = 0.019), significant increase n HDL (P = 0.017) in posttest compared to pretest. Furthermore, esearch findings showed that homocysteine (P = 0.005), ipoprotein A (P = 0.001), TG (P = 0.006), cholesterol (P = 0.015), DL (P = 0.022), and HDL (P = 0.004) levels between the two roups. These findings reveal the 3 sessions/week of erobic training cause reduction of homocysteine, lipoprotein A, nd lipid profile levels in sedentary middle‑aged men and can be ecommended for prevention of cardiovascular disease.
