Abstract: 

The purpose of present study was evaluating the influence of core stability exercise and vitamin D on some of physical fitness indices in young multiple sclerosis (MS) women.36 relapsing remitting MS women with EDSS≤3 (age: 32.72±6.57y, height: 164±4.23 cm, weight: 65.1±11.4 kg, disease duration: 4±1.20) participated in the study voluntarily and were divided randomly to four groups including three experimental groups of supplementations (SUP), exercise, SUP+ exercise and one control group. Before and after experimental period, all subjects participated in exercise tests including back muscle extensor strength test using dynamometer, muscular endurance of trunk using keeping trunk in angle of 60-degree, flexibility using Velez test, coordination test by repeated throwing of tennis ball, balance test using one leg stance. Core stability exercise was performed during 8 weeks and 3 times a week progressively (first session: keeping the motion for 5 S, with 6 repetitions, last session keeping the motion for 8 second with 10 repetition). Supplementation groups consumed 1500 IU vitamin D every two weeks. Statistical test of Analysis of Covariance was used for data analysis. Findings of the study indicated that inSUP+exercise group compared to control group significant increasing was observed in muscle strength (P=0.002) and endurance (P=0.001), flexibility (P=0.001) coordination (P=0.001) and balance (P=0.001), and compared to SUP significant increasing was found in muscle endurance (P=0.001), flexibility (P=0.001), coordination (P=0.001) and balance (P=0.001). Exercise (without SUP) compared to SUP caused increasing of muscle endurance (P=0.015), and compared to control group improved muscle endurance (P=0.02), coordination (P=0.031) and balance (P=0.001). SUP by itself did not cause any significant improvement in none of variables (P>0.05).According to priority exercise+SUP and exercise indicate positive influence on improving physical fitness indices.

Abstract: 

The aim of this study was to investigate the acute effects of continuous or high intensity interval exercise on plasma E-Selectin and WBC indices in CHD patients. Therefore, 30 male heart patients with Coronary Artery Bypass (CABG) and stenting (PCI) history voluntarily participated and divided into three groups: control, continuous and high-intensity interval (HIIT) group.Patients of HIIT group performed 8 repetitions of a 4-min interval training (2: 2 min exercise: recovery, intensity: 90: 30 %VO2peak), but continuous group performed a 30-min continuous exercise with a constant intensity at 60 %VO2peak. Blood samples were taken before and after exercise and their E-selectin and WBC indices were analyzed. The one-way ANOVA and Pearson correlation were used for statistical analysis. The results showed significant differences between the three groups for E-selectin increase (F2, 27=27.8, P<0.001). Bonferroni post hoc test has showed significant differences between control and interval (P=0.001), control and continuous (P=0.001) and also continuous and interval groups (P=0.009) in amount of increment. But no significant changes were observed in WBC indices responses between groups (P>0.05). It can be concluded that a session of exercise may stimulate the inflammation related processes that may be exacerbate in CABG and PCI patients by HIIT. Thus, using this type of exercise for just one session is not recommended in heart patients.

Abstract: 

Thirty-six male wistar rats aged two months (200±8 g), were randomly divided into four groups: 1- control (12 rats), 2- Nano selenium (12 rats), 3- training (six rats) and 4- Nano selenium+training (six rats). Then, they were supplemented with Nano selenium for 14 days (0.1 mg/kg/day) by Intraperitoneal injection. Six samples of heart tissue from groups of one and two during their resting time were collected.After two months training for groups three and four, second tissue samples were collected from all groups (in the two training groups immediately after last training session and in the other two groups during their resting time). Independent T test (P˂0.05) with SPSS21 software were used, in order to find differences in GPX, SOD, MDA and TAC between groups. First T test from first samples showed significant increase in GPX and TAC in the group two without no difference in MDA and SOD compared to the group one. Another T test between groups of one and two from second sampling indicated that, there is a significant increase in TAC in the group two compared to group one, but there were not any significant differences in other indices. The last T test from second sampling groups of three and four showed, there was a significant decrease in MDA and significant increase in GPX and TAC in group four compared to the group three, but There was not any significant difference in SOD between groups. Then short time supplementation of Nano selenium reduced the oxidative stress produced by exhausted exercise and consequently antioxidant system was amplified.

Abstract: 

For vaccine efficacy always using adjuvant has been considered by immunologists.Exercise can induce immune changes, and therefore, has been identified as an adjuvant for immune responses. The purpose of this study was to assess adjuvant effects of an acute endurance exercise on interleukin-2 and interleukin-12 cytokines of spleen cells in herpes simplex virus 1 vaccine model.24 BALB/c mice, 4 to 5 weeks old and with an average weight of 17.6 g, were divided into 3 groups: control, vaccine and vaccine plus an acute endurance exercise. Two weeks after three booster shots of vaccine, interleukin-2 and interleukin-12 levels was determined in spleen cell culture with ELISA method. One-ways ANOVA statistical test were used for data analysis. The result of this study indicated that there are significant differences between groups in interleukin-2 (P=0.008). Tukey post hoc test results showed significant differences between control and vaccine plus an acute endurance exercise groups (P=0.006). Changes in interleukin-12 cytokine production in vaccine and endurance exercise group were not significant. Result of current study showed that interleukin-2 levels from spleen cells increased following using an acute endurance exercise as an adjuvant. It seems that using an acute endurance exercise probably increased efficacy of immune system in direction to T helper 1 cells against virus infections.

Abstract: 

Diabetes mellitus affect male reproductive function at multiple levels including control of spermatogenesis. The aim of this research was assessing the effect of aerobic training on reproductive parameters in diabetic male rats. Thirty male Wistar rats (age: 2-3 mount, weight: 200-250 gr) randomly divided in to three groups: healthy control, diabetic control and diabetic trained (n=10 each). A single intraperitoneal injection of streptozotocin at a dose of 55 mg/kg was used for induction of diabetes. One week after streptozotocin injection, the endurance training protocol was performed for eight weeks (five bouts per week of treadmill running each 20-60min with 27 m/min) and forty-eight hours after the last training session, left epididymis of the rats was examined for studying sperm parameters and blood serum samples were examined for evaluating reproductive hormones. Data were analyzed using one-way ANOVAand turkey’s post hoc test at 0.05%. All of the sperm parameters (count, motility, morphology and viability) significantly were lower in diabetic rat when compared with healthy control group (P<0.05), but, the data showed a significant elevation in all of the sperm parameters in diabetic+training when compared with diabetic control group (P<0.05). Also, the data showed a significant high in sex hormones (testosterone, luteinizing hormone, follicle-stimulating hormone) in diabetic+ training when compared with diabetic control group (P<0.05). Exercise training can attenuate detrimental effects of diabetes mellitus on the sperm parameters and sex hormones in an experimental model.

Abstract: 

Physical activity reduces the risk of cardiovascular disease by modification of inflammation. The purpose of present study was to compare the effect of 8 weeks high intensity interval and moderate-intensity aerobic continuous training on predictive factor of heart failure in sedentary postmenopausal women. In this study, 30 healthy sedentary postmenopausal women (mean ± SE: age, 55.45 ± 0.49 years; weight, 71.26 ± 1.59 Kg) were selected in Isfahan and the subjects were randomly divided into three groups high intensity interval training, moderate-intensity aerobic continuous training and control.The high intensity interval training group participated in an exercise program at 60–90% of heart rate reserve and the moderate-intensity aerobic continuous training group participated in an exercise program at 50–65% of heart rate reserve but the control group did not participate in any regular physical activity program during this period. C-reactive protein and lipid profiles were compared using repeated measure ANOVA before and after 8 weeks in three groups. The results showed a significant decrease in C reactive protein and increase in high intensity lipoprotein of high intensity interval training group in comparison of other groups. A significant increase in HDL-C/LDL-C was seen in both training groups compared to the control group. Results of this study showed that high intensity interval training have more effective role than moderate-intensity aerobic continuous training exercises in preventing of cardiovascular diseases in postmenopausal women.

Abstract: 

The aim of the present study was to investigate the effect of endurance training on changes of serum concentration of MIF and its relationship with plasma white blood cells, glucose, and insulin changes in type 2 diabetic women. Twenty-Four subjects (age 55±6.6 years and weight 73±5.1) randomly divided in two groups, including control (n=12) and trained (n=12). Trained group performed eight weeks of endurance training including running at of 55-75% of their heart rate maximum for 40 to 60 minutes. Blood samples were collected before training protocol and 72 hours after the last exercise session. Plasma glucose was measured with glucose oxidase method; Serum MIF and plasma insulin concentration were measured by ELISA method. Difference of variables between groups were evaluated by analysis of covariance and multiple regression analysis was used to determine the possible contribution of white blood cells, glucose, and insulin changes to serum MIF changes after training protocol. Compared to the control group, concentration of serum MIF (P=0.03), plasma glucose (P=0.02), plasma insulin (P=0.04), white blood cell population (P=0.002), and HOMA_IR index values (P=0.01) in trained group significantly decreased after eight week of endurance training.Significant correlation was found between the exercise-induced changes in white blood cell population and serum MIF concentration (P=0.05). Sixty-three present of the variance in the changes in serum MIF concentration could be predicted by only the changes in white blood cell population. In summary, long-term endurance training is accompanied by decrease in white blood cell population and these changes could predict the exercise-induced suppression in serum MIF concentration after endurance training.

Abstract: 

This study investigates the effect of high intensity interval training and flaxseed oil supplement on pain feeling in male rats. Forty adult Wistar rats were randomly divided into eight groups (five in each group) including control- saline, training- saline, extracts dose of 100 mg/kg, extracts dose of 200 mg/kg, extracts dose of 300 mg/kg, extracts dose of 100 mg/kg- training, extracts dose of 200 mg/kg-training and extracts dose of 300 mg/kg-training. Training groups was given high-intensity interval training (10 weeks, five sessions in week) on a rodent treadmill at 90 to 95 percent of VO2max and supplement groups also received flaxseed oil. Pain threshold assessment by the hot plate test with a temperature of 55 ± 0.5oC. Statistical analyses were performed using a twoway analysis of variance. Least significant difference posts hoc test was used in the event of a significant (P<0.05). Result showed that supplement induced significant decreases in pain feeling (P=0.004) that extracts dose of 300 group has lower pain feeling than extracts dose of 100 (P=0.012). Pain feeling significantly lower in the group of supplements-exercises than exercise and control-saline groups (P<0.05). Flaxseed oil due to vitamins and unsaturated fatty acids has been able to reduce the pain of intense exercise. Therefore, flaxseed oil supplement to reduce pain of heavy physical activity is recommended.

Abstract: 

Excessive intake of sugar-sweetened beverages can lead to abnormalities in spermatogenesis and some of sex hormones levels. The purpose of this study was to investigate the effect of resistance training with progressive load on serum levels of sex hormones and number of epidydimal sperms count in rats fed with sucrose solution. Thirty-two male Wister rats (8-10 weeks old, mean weight 158.93±8.36 grams) were randomly divided initially into fed with and without 30% sugar solution groups, and after four weeks, each of these groups were divided into control and training groups (totally 4 groups). The training groups were subjected to 8 weeks progressive resistance training program, every other day, 3 days in week. Fasting serum levels of testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH), as well as epidydimal sperms count were measured. The results of two ways ANOVA with P≤0.05 indicated that interacting effects of resistance training and fed with sucrose solution induced a reduction in serum LH levels (P=0.02) and sperms count (P<0.01). Consumption of sucrose solution lead to a decline in serum LH and FSH levels, and sperms count (P<0.05). Progressive resistance training in the sucrose solution decreased serum LH (P<0.01) and FSH (P=0.04) levels compared with control group. It seems that high intensity resistance training in subjects with regular consumption of high sugar, can lead to impaired spermatogenesis by changing the levels of some sex hormones.

Abstract: 

The aim of this study was to evaluate the effect of an acute high intensity resistance exercise (AHIRE) on blood coagulation and fibrinolysis factors preand post 10 weeks resistance training in obese children.30 obese children (8-12 yr) voluntary with body mass index 27.08±0.96 kg/m2 were divided into control and training groups. The resistance training consists of ten weeks (3 times per week) with the intensity of 40-60% 1 repetition maximum (1RM) for eight exercises. Acute high intensity resistance exercise includes 2 sets of 12 repetitions with 75%1-RM for eight exercises. Blood samples were taken 4 times before and after training period (before and immediately after acute exercise). The AHIRE causes increase in tPA and vWF and causes decrease in PAI-1. There were no signigicant changes in protein S, protein C levels, platelet count, aPPT and PT in response to AHIRE in control and training groups. Ddimer levels increased in respose to exercise in taining group only. Also, ten weeks resistnace training causes reduction in fibrinogen and IL-6 levels in response to AHIRE compared to the control group. Before resistance training the results suggested that changes in coagulation and fibrinolysis factors were similar in both control and training groups approximately, in response to AHIRE. But after adaptation to resistance training, the training group showed higher fibrinolysis factors and lower coagulation and inflammation factors in response to AHIRE, that was showed with elevation in tPA, D-dimer and vWF and reduction in IL-6 and fibrinogen levels.

Abstract: 

The aim of this peper was meta-analysis of studies on the effectiveness of different exercise training on vascular endothelial function. To assessment studies in the field of vascular endothelial function search was done in databases; PubMed, scienceDirect, Scopus, Web of science, SID, Magiran and google Scholar with specified keywords among articles that were published in the years 1986 to 2016 both in Persian and English. After initial screening, full text search and critical appraisal, studies which pass the inclusion criteria were analyzed. Among imported article, 14 study which included 17 trials with meta-analysis inclusion criteria were analyzed. The results of the metaanalysis of studies showed that exercise can improve flow mediated dilation in healthy subjects (SMD=0.75, 95% CI 0.49–1.00, P=0.001) and patients with coronary artery disease (SMD=0.47, 95% CI 0.29–0.65, P=0.001). Although the effect size obtained for various exercise training are different, but considering the low number of studies, we cannot make an absolute statement about the superiority of one method of training. The exercise can be effective in improving endothelial function, although still high-quality research studies with sufficient sample size is needed.
