The aim of this study was to investigate the effects of acute high intensity interval exercise of judo (SJFT) on blood rheology response factors in trained judokas. For this, 12 judoka with at least two years of regular training voluntarily participated in this study. All subjects performed Special judo fitness test (SJFT) and blood samples collected before, immediately after and a half hours after the test. The results showed that plasma volume and red blood cell count was significantly decreased immediately after exercise (p<0.05), and the number of white blood cells, platelets and hematocrit were significantly increased after protocol (p <0.05). But all variables fall to primary level half an hour after protocol except white blood cells. The current study showed that the interval intense activity of judo can make an effective response in blood rheolog...

The aim of this study was to examine the effect one month aerobic exercise and vitamin E consumption on plasminogen activator inhibitor-1. Materials & Methods: In this quasi experimental study thirty inactive healthy collegiate fe-males voluntarily participated in the study and were randomly divided into three groups: training with vitamin (endurance training accompanied by 400 IU/day vitamin E), vitamin (400 IU/day vitamin E) and control (No vitamin and no exercise training). Endurance train-ing included 4 weeks of running on treadmill, 3 days a week. The duration and intensity of exercise in each session for the first week was 30 minutes at 65% of maximum heart rat and for the three remaining weeks were increased by 5 min and 5%, respectively. Two blood samples were taken before and 48 hours after training for measuring PAI-1 antigen. Results: Data analysis revealed that PAI-1 antigen increased in control group significantly (P≤0.05), while PAI-1 decreases and increases in training with vitamin, and vitamin groups, respectively were not statistically significant. Changes in PAI-1 were significantly different among the three groups (P≤0.05), but using analysis of covariance it was revealed that these differences were due to differences in resting levels of PAI-1. Conclusion: Based on the findings of present study, it could be concluded that short-term regular training combined with vitamin E consumption and chronic vitamin E consumption singly result in improvements in fibrinolytic system due to decrease or prevention of PAI-1 antigen.

This method has advantages such as avoidance of the organic solvents, production of pure products without any by-product, short reaction times and simple operation.

Mean lead levels in water and fish samples (119.50 ± 22.24 μg/L and 113.80 ± 33.11 μg/kg) were significantly higher than that of cadmium and chromium (p &lt; 0.05). Cyprinus carpio had highest metals content than Mugila auratus and Rutilus frisikutum. The evaluated metals values in water collected from Gomishan wetland (Pb, Cd, Cr and Zn values are 145.31 ± 35.32, 120.46 ± 11.44, 96.47 ± 6.05 and 82.02 ± 34.37 μg/L, respectively) were higher than the other sampling sites. The result is consistent with the findings accessed by evaluation of the metals in fish specimens. The metals concentrations in the fish and water samples were below the recommended limits. But, elevating levels of metals in water and fish made a serious concern about ecosystem and food chain contamination.

Various studies have been reported sedentary life style is one of the main causes of physical weakness and health-related problems in these individuals. The purpose of this study was to comparison of hand and trunk muscles strength in athletes and non-athletes mental retarded students and healthy students. Materials and Methods: Sixty adolescent students (mean age ± SD, 16.58 ± 1.13 years) were randomly recruited in this study. This sample is included thirty mental retarded (mean IQ ± SD, 62.87 ± 5.15) and thirty healthy age matched students. They were divided into four groups: Non-Active adolescent with Mental retardation (MR), Active adolescent with mental retardation (AMR), Non-active Healthy adolescent (HA) and Active healthy adolescent (AHA). The inclusion criteria for mental retardation were IQ between 50 and 70 and for being ...

The aim of this study is evaluation of protective effects of glutamine consumption on HSP70 and cortisol response. Materials and Methods: In this experimental study, 28 soccer players divided into 4 groups: control (n=7), supplement (n=7), exercise (n=7) and exercise supplement (n=7). Supplements (glutamine) and placebo (Dextrin) to a 0/5 gram per kg of body weight and volume of 5 ml per kg of body weight one hour prior to the exercise protocol was used. exercise protocol include a 3-stage 20minute run at 80% of maximum heart rate and rest 5 minutes. Blood samples of basal (after 12-14 hour overnight fasting), post exercise, and 90 minutes after exercise were gathered and HSP70 of serum and cortisol were measured with Elisa and RIA respectively. Data were analyzed with multivariate repeated measures (MANOVA) at p≤0/05 level. Results: There was significant diff...
