Observing the required standards in these stadiums are important in the following terms: safety, increasing the quality of the games, absorbing more spectators to the stadium, and obtaining permission to host the football games on an international level, etc. In this research, the Iranian football stadiums were compared with the standards in the European stadiums. The standards were divided into seven separate categories, i.e. adequate facilities for ordinary spectators and special spectators, reporters and mass media, players, coaches, referees, etc. For analysis of the findings two ways were applied: in inferential statistics the Mann - Whitney I] lest and in descriptive statistics percent age of frequency. The results demonstrated that the majority of the stadiums in Iran do not enjoy good conditions in terms of the seven above - mentioned categories. Consequently, given the importance of establishing essential standards in football stadiums, providing a comprehensive and strategic planning for the football stadiums across the country is suggested. دانشکده تربيت بدني دانشگاه تهران 1563-3306 19 v. 19 no. 2004 https://joh.ut.ac.ir/article_10388_26e5ec39449283078685928c1d1c3712.pdf دکتر لطفعلی بلبلی author دکتر حجت ا... نیکبخت author دکتر حمید رجبی author text article 2004 per The purpose of this study was to identify whether a period of 30 min-exercise in warm water for 17 days affects cardiovascular function in men in middle age. Fifteen warm water groups (WW, 40°C) and ten neutral water groups (NW, 29°C). Were divided into. They exercised (water head - out walking) 30 minutes per day in WW and NW for 17 consecutive days respectively. Measurements: echocardiography was performed four times (day 1, day 4, day 11 and day 18) during the study. Heart rate (HR) in WW in day 18 significantly decreased, stroke volume (SV,) and end diastolic volume (EDV) in WW significantly increased in day 4, day 11and day 18. End sistolic volume (ESV), ejection fraction (EF), sistolic blood pressure (SBP) and diastolic blood pressure (DBP) (lid not change in each group. Blood pressure (DBP) did not change in each group. The data suggest that walking in WW reduces resting HR, but increases SV and EDV. Thus, we can conclude that WW affects cardiovascular function in men in middle age. دانشکده تربيت بدني دانشگاه تهران 1563-3306 19 v. 19 no. 2004 https://joh.ut.ac.ir/article_10389_b95ae0c618f91ef5f528e58c3cc2fe5b.pdf دکتر عباسعلی گائینی author حمید اراضی author text article 2004 per The purpose of this study was to compare the effect of three different recovery periods (rest interval, on trained students’ bench press performance in University of Tehran. 15 trained students from University of Tehran (age = 25/28±2/01 years old, height = 176/33 ± 6/30 cm and weight = 73/068 ± 8/33kg) were selected from volunteers. They were invited to the weight-training hall in kooy of University of Tehran and performed 4 sessions of bench press every 8 hours. In the first session, one repetition maximum (1 RM, was measured. From the second to the fourth session, 4 vets of bench press with 75% 1RM up to voluntary exhustion along with inactive rest intervals including I to 3 ratio of work to rest, 60% maximum heart rate and 3 minutes rest were practiced. Data showed: There is a significant difference among rest intervals with 1 to 3 ratio of work to rest, 60% maximum heart rate and 3 minutes rest (p = 0.00). There is a significant difference between bench press performance and the three mentioned rest intervals (p =0.00). Three minute-rest intervals have better effect on the performance of bench press (p =0.00). دانشکده تربيت بدني دانشگاه تهران 1563-3306 19 v. 19 no. 2004 https://joh.ut.ac.ir/article_10390_0e285301bc4631d36f25a035dba4367d.pdf دکتر فرهاد رحمانی نیا author دکتر حمید محبی author ظاهر اعتماد author text article 2004 per دانشکده تربيت بدني دانشگاه تهران 1563-3306 19 v. 19 no. 2004 https://joh.ut.ac.ir/article_10391_c81269075413fa42a9a98eba8838b47b.pdf دکتر مجید جلالی فراهانی author دکتر محمود گودرزی author دکتر محمد خبیری author دکتر حسن اسدی author text article 2004 per The purpose of the present research is to compare the organizational structure and status among football federation of Iran, fifa and some selected countries, and to provide suggestions for an ideal pattern.
