Abstract
The purpose of this study was determine the effect of upper body plyometric training on anaerobic power and record of 25 meters front crawl performance in 10 years old swimmer boys. 16 swimmer boys chosen voluntarily (The mean age was 9.9 ± 0.7 years ، weight 45.9 ±9 kg , Height 149.8 ± 5 cm، BMI is 19.20 ± 3 Kg / m 2 ) And Subjects divided into two groups of training (n=8) and control(n=8).Before and after the implementation of the protocol investigate test 25 meters front crawl performance at the distance 10, 20 and 25 metrs and the number of hand strocke to check the performance of the swimming also anaerobic hand wingiting test function was evaluated. To analyze data, used the covariance test.The results showed six weeks upper body plyometric training Performance Indicators an hands Front crawl Including Peak power increased Significantly (18%) but the average power increase (7%) was not significant (p>0.05). Also, Swimming performance at of 10 meters) 8% (,10 to 20)6%( and 25 meters distance( 3/80%) growth in compare to control group that was significant(p <0.05) As well as in the number of hand strocke, Plyometric training group although had growth in swim 10 meters (11%), 10-20 meters (7.5%) and in 25 meters distance (5.33%) but the isnt significance (p>0.05). results indicate that six week upper body plyometric traning to an increase and improvement in the measured parameters, and can be used as a complementary training method in young swimmers.

Abstract
The prevalence of obesity in postmenopausal women is higher compared to men. A decrease in estrogen with menopause leads to dysfunction in mitochondria. The purpose of this study is to investigate the effect of high intensity aerobic training(HIT) on the copy number of mitochondrial genome (mtDNAcn) and mitochondrial transcription factor A(Tfam) in visceral adipose tissue(VAT) in ovariectomized(OVX) rats fed with high-fat diet(HFD). 40 rats (8 weeks, 200±20 gr) were divided into 5 groups:1) normal diet (ND), 2) ND+OVX, 3) HFD, 4) HFD+OVX, and 5) HFD+OVX+HIT. HIT performed aerobic training (80-85% of maximum oxygen consumption) for 8 weeks/5 sessions/42 minutes.48 hours after the last training session, VAT samples were taken to evaluate mtDNAcn and Tfam gene expression by qRT-PCR method. ANOVA and LSD tests were used to compare the differences between groups. OVX and HFD didn’t lead to a significant change in Tfam gene expression, but caused a significant decrease in the mtDNAcn compared to the control group. HIT caused a significant increase in Tfam gene expression compared to the control group and Tfam gene expression and mtDNAcn compared to the HFD+OVX. Hence, HIT improves mitochondrial function through mtDNAcn and Tfam gene expression in VAT in OVX rats fed by HFD.

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.

Abstract
Background and aim: The purpose of this study is to examine how eight weeks of general exercises (GEs) combined with cognitive functional therapy (CFT) affect women with chronic non-specific low back pain (CNSLBP) in terms of pain, quality of life (QoL), and muscle endurance.
Methods: 45 women with CNSLBP participated in this study for eight weeks in three groups: GEs, GEs with CFT, and control. Pain, QoL and muscle endurance were evaluated by visual analogue scale (VAS), SF-36 questionnaire, and Biering-Sorensen test, respectively. Mixed-model repeated measure test with repeated measurement design was used for data analysis.
Results: The results revealed a significant difference in the investigated variables between the pre-test and post-test for the intervention groups, but no difference was seen in the control group.
Discussion and final conclusion: The group of GEs combined with CFT distinguished itself significantly from the group of GEs in the comparison of the factors of physical performance, emotional health, and general health from sub-sections of QoL, and also muscular endurance. According to the results, it is recommended that women with CNSLBP use GEs in combination with CFT to reduce pain, improve QoL, and increase muscle endurance.

Abstract
The purpose of this study was to investigate the impact of combining aerobic exercise (AE) and vegetarian diet (VD) on blood pressure and body weight in adults with overweight and obesity. The PubMed, Web of Science, Scopus, and Google scholar databases were searched until February 2023 for English articles, and 1065 articles were found. Meta-analyses were performed to compare the impact of aerobic exercise and vegetarian diet on body weight, blood pressure in adults with overweight and obesity. Data analysis was performed using random effect model and weighted mean differences (WMD). The results of meta-analysis of 25 studies with 10192 adults showed that combined aerobic exercise and vegetarian diet significantly decreased in body weight [WMD=-4.63, p=0.001] , systolic blood pressure [WMD=-6.94, p=0.001] , and diastolic blood pressure [WMD=-4.5, p=0.001] , in adults with overweight and obesity. Aerobic training alongside vegetarian diet as a non-medication approach for weight loss and blood pressure control in adults with overweight and/or obesity. In addition, aerobic exercise and vegetarian diet with both types of duration (less than 12 weeks and more than 12 weeks) cause a significant decrease in blood pressure in adults with overweight and obesity.
