Abstract
Introduction and aim: The aim of present study was to assess the effect of six weeks Badminton training
on changes of stress and cortisol levels in non-athletic female students. Materials and Methods: In this
study estimated stress of 120 non-athlete students by stress questionnaire (HAD scale). Were measured
Among subjects who had suffered highest stress, 30 subjects with a mean age of 86/2 ± 22 years, height
56/5 ± 163 cm and weight 95/4 ± 57 kg were selected. Cortisol were measured by the bloodletting. The
subjects were divided into two experimental and control groups as homogeneous. But the control group did
not perform any activity. After training protocol variables were measured again in the same conditions. To
estimate the effect of independent variables on the dependent variable of the t-test and the independent ttest
to compare groups with a significance level (p <0/05) was used. Data were analyzed using spss and
Excel software.
Results: The results of this study showed that doing a six-week badminton practice reduces cortisol levels
(p =0.005), and decreasing stress (p =0.03) in the experimental group.
Conclusion: There was significant change in levels of cortisol and stress in experimental group.

Abstract
The aim of this study was comparing professional futsal practice sessions with and without blood flow restriction on angiogenesis and angiostatin stimulation in active young men. Among physical education students, 12 volunteer selected and randomly divided into two groups of exercise with and without blood restriction. All of the subjects did the 3 vs. 3 professional futsal practice in 6 repetition of two minutes. One minute determined as resting time between the repetitions. In exercise group with blood restriction, a cuff on the thighs with pressure of 140 Mm Hg were applied. The blood samples were collected before and after the exercise sessions to determine the ratio and values of VEGF and endostatin concentration. Elisa method was used to measure the variables. To determine within and between group differences, Paired T test and Independent T test were used respectively at significance level of 0.05. The results showed no significant differences for the measured variables between the groups. However, VEGF significantly decreased in the two groups after exercise session (P=0.002). The ratio of VEGF to endostatin significantly increased in exercise with blood flow restriction group (P=0.002), but not in the Exercise group (P=0.006). Interestingly, the endostatin concentration increased significantly after the trial (BFR: P=0.003, NONBFR: P=0.005). Blood lactate was significantly higher in exercise group with blood restriction(P=0.003). In conclusion, a professional futsal practice session can decrease blood level of VEGF and increase its endostatin.

Abstract
It is estimated that by 2035, more than 130 million adults will suffer from various types of cardiovascular diseases. Therefore, it is very important to know the pathogens of cardiac diseases and investigate new treatments. Also, despite continuous progress in diagnosis, patient education, and risk factor management, myocardial infarction (MI) remains one of the most common causes of morbidity, hospitalization, and mortality worldwide. The events associated with MI are highly complex and characterized by rapid metabolic and biochemical changes. Exercise training is an effective cardioprotective strategy that reduces adverse effects of MI and ischemia/reperfusion (I/R). Multiple signaling pathways of exercise preconditioning in mitigating MI-induced cardiac damage is one of the topics that has attracted much attention. In this article, some of the contributing factors in exercise-induced cardiac protection, including mitochondrial changes, metabolic changes, vascular adaptations, antioxidant capacity, heat shock proteins, cyclooxygenase levels, ATP-sensitive potassium channels, adenosine, protein kinase C, calcium and klotho homeostasis are discussed.

Abstract
Nowadays, the use of traditional herbal remedies for the prevention and treatment of diseases along with exercise has become very popular. The aim of this study was to investigate acute effect of hydro alcoholic extract of melissa officinalis on metabolic rate, substrate oxidation and salivary cortisol during and after high-intensity interval exercise (HIIE) in inactive women. Ten inactive women were selected based on criteria (BMI 22.28±0.60 kg/m2). Individuals participated in two separate sessions. In the first session, extract of melissa officinalis (500 mg) were intake one hour before HIIE. In the second session, the placebo (500 mg of starch) was intake. The HIIE program consisted of 11 alternates (1-minute with 90% vVO2max followed by 2-minute rest intervals with 60% vVO2max). Pre, during and after HIIE, respiratory gases was measured using the respiratory gas analyzer and was used to calculate metabolic rate (Energy Expenditure, VO2) and substrate oxidation (Fat oxidation, Respiratory Exchange Ratio (RER)). Heart rate monitored by polar sensor. Salivary cortisol after collection was measured by chemiluminescence method. Based on results, there was no significant difference in VO2 (P =0.51), Fat Oxidation (P= 0.9), RER (P= 0.76), Heart rate (P= 0.42) and energy expenditure (P=0.6) between melissa officinalis and placebo intake. Also, there was no significant difference in salivary cortisol (P= 0.15). Generally, hydro alcoholic extract of melissa officinalis supplement intake along HIIE has no effect on metabolic rate, substrate oxidation and cortisol level in inactive women.

Abstract
Fatigue is one of the most common symptoms among individuals with multiple sclerosis (MS). The imbalance of inflammatory cytokines in the brain causes mental fatigue. It is believed that aerobic exercise may moderate the level of inflammation of cytokines and thus reduce mental fatigue. This study was conducted to investigate the effect of swimming aerobic training on pro-inflammatory factors (interleukin 6) and anti-inflammatory factors (interleukin 10) to evaluate mental fatigue in the brains of female mice after EAE induction. In this research, 21 mice (8 weeks old, 18 to 20 grams) were divided into three groups: healthy control, EAE control, and EAE swimming aerobic exercise. The animals in the training group performed moderate-intensity swimming exercises for 4 weeks, with 5 sessions per week, each session lasting 30 minutes. The western blot method was used to analyze the research variables. The results showed no significant difference in the amount of IL-6 between the EAE group and the swimming training group, but the amount of IL-10 in the swimming training group showed a significant increase compared to the EAE group. The ratio of IL-10/IL-6 values between the swimming training group and the EAE group was also not significant. It seems that moderate-intensity swimming aerobic exercises, without changing the pro-inflammatory factor, along with increasing the anti-inflammatory factor IL-10, can lead to an improvement in the balance of the inflammatory index and a reduction in fatigue in the EAE group and the swimming exercise group.
