The Effect of One Period of Progressive Resistance Training on Plasma Levels of Omentin-1, Insulin Resistance, Non-high Density Lipoprotein and Some cardiovascular Risk Factors in Men

Background and Objectives: Adipose tissue as an endocrine gland produces a large number of intermediate compounds that are involved in many metabolic processes. Omentin-1 as a beneficial adipokine, has attracted more attention from researchers due to its favorable effects on inflammation, glucose homeostasis, and prevention of cardiovascular disease (CVD). The aim of this study was to investigate the effect of 8 weeks of progressive resistance training on plasma levels ofomentin-1, insulin resistance, non-high density lipoprotein (non-HDL), and some cardiovascular risk factors in overweight and obese men. Methods :In this quasi-experimental study, 20 healthy overweight and obese male subjects (22.75&plusmn;1.29 years, 89.22&plusmn;13.08kg, 28.36&plusmn;3.98kg/m&sup2;), were selected as available subjects and randomly assigned to training (n=10) and control (n=10) groups. Exercise protocol included 8 weeks of resistance training (4 sessions/week, 60min/session). Blood samples were taken before and after the exercise to evaluate blood variables. Plasma omentin-1 level was measured using ELISA method. Data were analyzed by paired and independent t-tests at the significance level of p<0.05. Results: After 8 weeks of resistance training in the experimental group, the level of serum omentin-1 insignificantly increased (p=0.79), and the levels of non-HDL-c (p=0.024), TG (p=0.017), TC (p=0.032), and systolic blood pressure (p=0.002) significantly decreased. There were no significant changes in other variables. Conclusion: The results of this study showed that 8 weeks of resistance training, in spite of positive effect on some cardiovascular risk factors (non-HDL-c, triglyceride, total cholesterol), had no significant effect on omentin-1 and insulin resistance

The effect of sesamine and aerobic exercise on plasma levels of total antioxidant capacity and glutathione peroxidase in athlete men

Background: One the ways to deal with the adverse effects of oxidative stress caused by exercise activities is to use oral antioxidant supplements or to apply natural remedies. Sesamin is the most prominent lignan compound found in sesame seeds, one of the two highest sources of lignans in the human diet (the other being flax). Sesamin is catered to be a nutritional supplement that confers antioxidant and anti-inflammatory effects or possibly being an estrogen receptor modulator and fat burner. For this purpose, the present study was conducted to evaluate the effect of 10 weeks supplementation of sesamin and aerobic exercise on plasma levels of total antioxidant capacity and glutathione peroxidase in athletic men. Methods: In this quasi-experimental study, in Azarbayjan Shahid Madani University of Tabriz City from January to March of 2016 ,40 male subjects aged between 25 and 20 were randomly selected from placebo (10 subjects) and aerobic exercise (10 students), aerobic training+sesamin (10 people) and sesamin (10 people). The aerobic exercise protocol is (ten weeks / three days / 30-35 minutes). Blood samples were collected from subjects in six stages to evaluate the considered variables. Measurement of levels of antioxidant capacity and glutathione peroxidase measurements were conducted by the Antioxidant capacity and GPX assay kit (ZellBio, German). For data analysis, repeated measures of variance analysis at a significant level of 5 hundredths were used by employing SPSS software, version 20 (SPSS Inc., Chicago, IL, USA). Results: Subjects who took sesamin supplementation and performed aerobic exercise showed a significant difference in the levels of total antioxidant and glutathione peroxidase capacity in the groups (P<0.05). Also, the changes in total antioxidant and peroxide levels after interference (steps 4, 5, 6) and before interference (steps 1, 2, 3) had meaningful differences in obtained results (P=0.001). Also, the interactive effects of group and time on total antioxidant capacity and glutathione peroxidase were also significant (P=0.001). Conclusion: Aerobic exercise and supplementation of sesamin is an effective method to improve the health of mens athlete's immune system. In addition, combining supplementation with aerobic exercise can increase some of the beneficial effects of exercise during a 10-week period

Assessment of species composition and CPUE (catch per unit effort) of commercial fish caught with bottom gillnet in Jask coastal waters

Tiger– toothed croaker (Otolithes ruber) is considered as a commercially important target species for fishermen in south of Iran, due to its high economic value and marketability. This investigation was carried out using bottom monofilament gillnet with mesh size (stretch mesh) of 8.5 cm and net height of 6 m, made of nylon twine (Polyamide) and a hanging ratio of 50% in order to determine species composition and Catch Per Unit Effort (CPUE) in Jask coastal waters during 2011- 2012 fishing season. A total of 7651 individuals belonging to 39 species and 36 families at 178 times shooting were captured and measured. O. ruber was the dominant species in this area (26.81 %.). The length range of this species was between 17.3– 58 cm and the maximum frequency was in 35-38 cm length class and the length average was 36.93 ± 5.02 cm. The current fishing pattern showed that 37.19% of catch is below length at first maturity. The CPUE of O. ruber was the highest in March. (2463.33 g/ panel days) and the lowest in November (11224 g/ panel days)

Effects of training Pilates and Aerobic on happiness and desire for physical in inactive women

Background & Aim: Balance between mental and physical health plays an essential role in happiness and desire for physical activities in individuals. On the other hand, Pilates and aerobic exercises play a pivotal role in creating balance between mental and physical health, in a way that sport activities could improve self-satisfaction and happiness. This study aimed to evaluate the effect of eight weeks of Pilates and aerobic exercises on happiness and desire for physical activities in inactive women. Materials & Methods: This quasi-experimental research was conducted on 40 inactive women in Tabriz, Iran in 2016. Subjects were selected through random sampling and were divided into four groups of control, Pilates, aerobic, and Pilates-aerobic program. In total, the participants attended 24 60-minute Pilates and aerobic sessions (three times per week) and filled the questionnaire of happiness and desire for physical activities before and after the intervention. It is notable that the reliability of the research tool was estimated at the Cronbach&rsquo;s alpha of 0.93 and 0.87, respectively. In addition, data analysis was performed in SPSS version 20, and P-value less than 0.05 was considered statistically significant. Results: According to the results of ANOVA and Tukey&rsquo;s test, intervention caused a significant increase in both happiness and desire for physical activities in the subjects. However, there was no significant difference between the groups regarding the level of improvement. Conclusion: According to the results of the study, physical exercises and sports, specifically Pilates and aerobic exercises, are not only valuable tools for maintaining physical health, but also they have a close correlation with mental health and happiness of inactive women. Therefore, it is suggested that these types of activities be applied as a solution for creating and increasing a good mood in women&rsquo;s society

Effect of an Incremental Interval Endurance Rope-Training Program on Antioxidant Biomarkers and Oxidative Stress in Non-Active Women

Background & Aim: Aerobic exercises are recommended as an important technique to control and prevent cardiovascular diseases and metabolic disorders. Therefore, this study aimed to evaluate the effect of an incremental interval endurance rope-training program on antioxidant biomarkers and oxidative stress in non-active women. Materials & Methods: This quasi-experimental research was conducted on non-active female subjects (overweight and obese) at the age range of 20-30 years. In total, 20 eligible participants were selected via random sampling and divided into two control and intervention groups of 10. The training program included eight weeks (four 45-minute sessions per week) of incremental rope training. Data analysis was performed in SPSS version 20 using dependent and independent t-tests at the significance level of 0.05. Results: The results of dependent t-test showed a significant increase in the level of superoxide dismutase enzyme, total antioxidant capacity, and glutathione peroxidase, compared to the pre-test state of the subjects (P0.05). Moreover, results of independent t-test demonstrated a non-significant increase in the total antioxidant capacity and glutathione peroxidase in subjects of the intervention group, compared to the control group. On the other hand, there was a significant increase and decrease in superoxide dismutase and malondialdehyde, respectively (P<0.05). Conclusion: According to the results of the study, rope training increased antioxidant defense and decreased oxidative damage and lipid peroxidation. Therefore, it seems that this type of training can prevent cardiovascular diseases in overweight and obese individuals
