The subjects in each group completed 65 minutes of exhaustive exercise after14 days of supplementation. Blood samples were collected before supplementation and immediately before and after the exhaustive exercise. The data were analyzed using variance analysis and dependent t tests. Results showed a significant increase in serum vitamin E (p=0.000) in supplemented group. Also, serum ICAM-1 insignificantly increased in supplementation (p=0.128) and placebo (p=0.095) groups. However, no differences were found in serum ICAM-1 between supplementation and placebo groups (p=0.710) within any time span. In conclusion, 400 international unit of vitamin E supplementation for 14 days (tocopherol isomer) did not have a significant effect on serum ICAM-1 induced by exhaustive exercise دانشکده تربیت بدنی دانشگاه تهران 20089325 4 v. 10 no. 2012 25 41 https://jsb.ut.ac.ir/article_21996_126970713a2ae6fc9410f07914ca1f65.pdf dx.doi.org/10.22059/jsb.2012.21996 amir hossein haghighi دکترای فیزیولوژی دانشگاه حکیم سبزواری author ali heshmatikeya کارشناس ارشد فیزیولوژی ورزش author alireza hosseini دکترای فیزیولوژی دانشگاه حکیم سبزواری author text article 2012 per Although studies have reported the positive effects of caffeine on aerobic performance, results of its ergogenic effects on anaerobic performance and intense and short-term exercise are equivocal. The aim of this study was to determine the effect of moderate and low doses of caffeine on maximal strength, muscular endurance and power in male body builders. For this purpose, 12 male body builders (mean age 26.83±5years, height 174±4.04 cm and body weight 77.41±3.8 kg) were selected voluntarily. Study design was crossover. Subjects were divided into four groups of control, low dose of caffeine (2.5 mg/kg), moderate dose of caffeine (5 mg/kg) and placebo (starch powder as capsules). Then, subjects performed tests of one-repetition maximum (1RM) for maximal strength, repetition to fatigue at 70% of 1RM for muscular endurance and number of repetitions in 15 seconds with 80% of 1RM for muscle power on the bench press (BP) and leg press (LP). The data were analyzed using analysis of variance (ANOVA) with repeated measures and dependent t test. The results showed that there was a significant increase (P دانشکده تربیت بدنی دانشگاه تهران 20089325 4 v. 10 no. 2012 43 59 https://jsb.ut.ac.ir/article_21997_574b524e45fd920da3151dcf193ddd28.pdf dx.doi.org/10.22059/jsb.2012.21997 kamal Ranjbar دانشجوی دکتری فیزیولوژی ورزشی دانشگاه بوعلی همدان author maryam norshahi دکترای فیزیولوژی دانشگاه شهید بهشتی author maysam gholamali دانشجوی کارشناسی ارشد فیزیولوژی ورزشی دانشگاه شهید بهشتی تهران author saed merzai کارشناس ارشد دانشگاه مازندران author text article 2012 per Although it is well established that women are more likely to sustain certain connective tissue injuries than men during physical activities, this difference between males and females is not clear. Gelatinases degrade components of tendon tissue. Thus, in this research, the effects of gender on serum gelatinases (MMP-2 and MMP-9) at rest and in response to acute endurance exercise were investigated. 15 healthy and active men and 15 healthy and active women participated in this study. Subjects exercised for one hour at 70% of VO2max on an ergometer 72 hours after VO2max had been determined. Two mls of antecubital vein blood was collected before, immediately after and 2 hours after the exercise. Serum MMP-2 and MMP-9 were measured by ELISA method. ANOVA with repeated measures and one-way ANOVA were used to analyze the data (P?0.05). The results showed that MMP-2 and MMP-9 at rest in men and women were not different. MMP-2 decreased in both groups immediately after the exercise while this decrease in women was not significant. Serum MMP-2 did not change in both groups in response to the exercise. There was no difference in the changes of MMP-2 and MMP-9 in response to the exercise between the two groups. According to the results of this study, the gelatinases at rest and in responses to acute exercise is not an effective factor in more vulnerability of tendon tissues in women in response to the exercise. Presumably, other hormonal and structural factors of women’s tendon are responsible for more injuries دانشکده تربیت بدنی دانشگاه تهران 20089325 4 v. 10 no. 2012 61 76 https://jsb.ut.ac.ir/article_21998_10ce3de1a5619cd1ddc874808ff3c087.pdf dx.doi.org/10.22059/jsb.2012.21998 farhad daryanoosh دانشگاه شیراز-کارشناس ارشد author farhad daryanoosh دانشگاه شیراز-دکتری author davood mehrabani گروه فارماکولوژی دانشکده پزشکی دانشگاه علوم پزشکی شیراز author text article 2012 per Producing soluble or cellular components is one of the main functions of immune system which immunes the body against any kinds of inflammation. The aim of the present study was to investigate the plasma level changes of IL-17, CRP, and CPK in male mice after 8 weeks of aerobic exercise and omega-3 consumption. For this purpose, 170 male mice (mean age of two months and mean weight of 35±1 g) were selected. At the beginning, 10 mice were killed in order to determine the amounts of pretest variables. The rest were randomly divided into four groups of control (n=40), supplement (n=40), training (n=40), and supplement with training (n=40). 0.2 ml (0.06 ml/g of body weight) oil fish (Omega-3) containing DHA and EPA were consumed by supplement and supplement with training groups every day for eight weeks. The animal training protocol was performed on animal treadmill 5 sessions a week for eight weeks.

As QOL decreases after health diseases, the aim of most medical health care systems and cardiac rehabilitation centers are to enhance QOL of heart disease patients. The aim of this study was to investigate the effects of continuous and interval exercise training on quality of life of heart patients after coronary artery bypass graft surgery (CABG). For this purpose, 20 POST CABG patients (18 men, 2 women with mean age: 57.05±8.91 and mean BMI: 26.98±3.20 kg/m2) were divided into aerobic continues training (30 – 60 min. and intensity of 70 – 85% of maximum HR, n=10) and aerobic interval training (28-44 min. and intensity of 75 – 90% of maximum HR, n=10). They performed the exercise training three times a week for 8 weeks. QOL was measured by Persian version of SF-36 questioner. Paired t test was used to analyze the data. SPSS version 16 was used to analyze all statistics. Results showed that both aerobic interval and continuous exercise programs had a beneficial significant effect on QOL and its dimensions of physical function (continuous P دانشکده تربیت بدنی دانشگاه تهران 20089325 4 v. 10 no. 2012 115 129 https://jsb.ut.ac.ir/article_22001_941bba0805df08fb8e4e19d7afa8dbbb.pdf dx.doi.org/10.22059/jsb.2012.22001 Farnaz Torabi استادیار دانشگاه پیام نور author ahmad farokhi استاریار دانشگاه تهران author text article 2012 per The aim of this study was to investigate the effect of different rhythms of music on some central and peripheral fatigue indices in non-athlete young females. For this purpose, 38 healthy female students were randomly divided into three groups: fast music group or EXP1 (N=13, M+SD age: 22+2 years), slow music group or EXP2 (N=13, M+SD age: 23+2 years) and control group (N=12,M+SD age: 23+2 years). At first, pretest was performed under the same condition as the training condition; then, training program was performed for six weeks, two sessions per week and finally posttest was performed. The training program included pedaling on an ergometer until exhaustion. The experimental groups listened to music by headphones while training; control group received no musical intervention. Results of finger tapping test showed no noticeable difference in peripheral fatigue between experimental groups and control group. The results of chart for continual naming of colors test confirmed the central fatigue in control group compared with fast and slow music groups. Data analysis by one-way ANOVA showed no significant differences in fatigue indices among the three groups in the pretest (P>0.05). But in the posttest, workload of exhaustion (p=0.022) among groups was significant. Tukey post hoc test showed a significant difference in all variables between experimental groups and control group (P0.05). Generally, it can be concluded that music together with training delays central and peripheral fatigue and finally improves sport performance. دانشکده تربیت بدنی دانشگاه تهران 20089325 4 v. 10 no. 2012 147 131 https://jsb.ut.ac.ir/article_22002_3db67014a643ba3bd8069fb93834c526.pdf dx.doi.org/10.22059/jsb.2012.22002
