The aim of this investigation is to compare the effect of high intensity interval training in hypoxia (O₂: 14%) and normoxic (O₂: 21%) conditions on pre-inflammatory cytokines (IL-6, TNF-α, IL-1β) and blood cells in response to exhaustion exercise. 16 male athletes were divided up randomly into 2 groups (hypoxic and normoxic groups). They did exhaustive exercise (ergometric cycle) and blood samples were taken before and after the exercise. These 16 athletes carry out Ergometer maximum work rate (Wmax) in 12 sessions during two weeks. Once more, afterward two weeks, all athletes experienced exhaustive exercise before and after which blood samples were...

Applying a bibliometric analysis method, the present study tries to investigate scientific achievement in sports and exercises and examine its relation to practical performance, using scholarly papers indexed in ISI as substitutes of scientific productivity and medals won in olympic competitions for representations of athletic performance. The results showed that Sport Sciences is a small scientific community with a limited body of literature but a great number of contributing countries. The counts of sports scientific publications revealed to be exponentially increasing, signifying a stable annual growth comparable to that of the global science system. There is also a significant correlation between countries' success in olympic games and their scientific productivity. However, the former is found to have no significant correlation with the counts of sports-specific publications. It implies that though the scientific productivity in sports have no direct effect on athletes' performance in olympic games, the overall development of countries determine their performance in competitions. Consequently, to reach superiority in sports a complete evolution in all aspects of science, sports, economy and human development is necessary.

Sixty-three rats were randomly assigned into sedentary (n = 15), sham (n = 7), and exercise groups (n = 41). Rats in the exercise groups performed 5 consecutive days of HIIT on treadmill: 5 min warm up with 50 % VO2max, 6×2 min with 95-105 % VO2max (about 40 to 45 m/min), 5×2 min recovery with 65-75 % VO2max (about 28 to 32 m/min), and 3 min cool down with 50 % VO2max, all at 0 % grade. Animals exposed to an in vivo cardiac IR surgery, performed at days 1, 7, and 14 following the final exercise session. Ischemia-induced arrhythmias, myocardial infarct size (IS), plasma lactate dehydrogenase (LDH) and creatine kinase (CK) activities were measured in all animals. Compared to sedentary rats, exercised animals sustained less IR injury a...

Method: For this purpose 88 two-month-male rats, with mean body mass of 240± 6 gr, randomly were divided into four groups: control and sedentary ( CS n = 22), Training ( T n = 22) , Diabetes and sedentary ( DS n = 22), and Diabetes and training ( DT n = 22). DT and T groups had 12 weeks aerobic exercise on treadmill. Each exercise bout included: warm up, running (Main training), and cod own. The training time and intensity progressed from 20min, 15 m/min, and reach to 60 min 25 m/ min, respectively at the end of exercise protocol. Five training sessions were included each week. In order to measure the levels of plasma glucose, HDL and cholesterol, Blood samples were taken from tail vein twice (at the start and end of exercise period). Heart tissue was taken from all groups before starting exercising and after it was finished. Then the heart weight, left ventricular weight, ratio of heart weight to body weight and ratio of left ventricular weight to heart weight were measured. Spss-13 software was used for statistical analysis of data. Statically method of ANOVA was used for data analysis and in the case of significant result (α≤0.05) TUKEY test was used as follow test. Results: The results of this study showed an increase of 27% and 50% in mass of left ventricular in DT and T groups respectively. Also significant decrease of cholesterol and glucose variables and significant increase of HDL variable were observed in DT and T groups respectively. The investigation results indicated a significant difference in mean heart rate changes among all groups. Conclusion: According to these findings, it can be claimed that the aerobic exercise can cause some positive effects on the heart's function and structure in diabetic's patients (Increased Volume and left ventricular wall thickness and decreased rest heart rate). In spite of the increase in systolic blood pressure as a result of diabetes, exercise trainings can decrease this change to some extent. No significant differences were observed in the mean systolic blood pressure among all groups.

The purpose of this research was comparison of emotional intelligence and its subscales between athletes and non athletes based on some demographic variables. So, 200 athletes in different sport fields who had been exercising in Shiraz clubs and 40 non athletes were selected as control group and they were evaluated by Baron emotional intelligence Scale and by special sheet of demographic characteristics. One-way variance analysis, t-test and Pearson correlative coefficient were used for data analysis. Results showed that there was a significant difference in emotional intelligence score between athletes and non athletes (P=0.05). Also, this difference was seen in mixed scales of intrapersonal intelligence, adaptability and general mood (P=0.05). In addition to above cases, athletes acquire higher scores in subscales of proble...

Herein, we would like to investigate the effects of incremental aerobic training and fish oil supplementation on the plasma levels of CRP, CPK and IL-17 in trained mice. One of the major roles of immune system is to produce soluble or cellular components that provide the immunity against inflammatory agent. The purpose of this study is to investigate distinct and combine effects of incremental aerobic training and fish oil supplement on plasma levels of IL-17, CPK and CRP in trained male mice. Totally, 54 healthy male mice (2 months old, weight= 34±1 grams) were selected. At first 10 mice were killed to determine base line values, the rest of them were randomly divided into four groups, control group (C, n=11), supplement group (S, n=11), training group (T, n=11) and supplement-training group (ST, n=11).The supplement and supplement-training groups were fed with 0.2cc/day fish oil for 8 weeks.

The purpose of this study was to examine the effect of ω-3 supplementation on pulmonary function in cadets participated in army ranger training. Materials and Methods: In this study, 41 army cadets (mean age, 18.6±0.9 years) were randomly allocated to the supplement (S, n=21) and placebo (P, n=20) groups. The two groups participated in army classic military training 4-5 days/week for 8 consecutive weeks. The S and P groups were asked to consume 1000 mg/day ω-3 and placebo per day for 8 weeks, respectively. Pulmonary function was assessed at the first and end of the training. Results: Results indicated a significant difference in FEV1, FVC, MVV, FEF25-75%, FIV1 at the end of the training compared to those obtained at the beginning in both groups; however, the changes were markedly greater in the S group (P≤0.05). Conclusion: It can be concluded that the supplementation of ω-3 (1000 mg/d) can induce positive alteration in different pulmonary function indices.
