Abstract
Exercise training and vegetarian diets have been accepted as suitable and non-pharmacological methods to weight loss, and improve cardiovascular factors such as blood pressure. 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). Also, the confidence interval of 95% was considered. Also, the I2 test was used to determine heterogeneity, and the Funnel plot and Egger tests at a significant level of 0.1 were used to determine publication bias. 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, (CI: -5.7 to -3.56), p=0.001], systolic blood pressure [WMD=-6.94, (CI: -7.86 to -6.01), p=0.001], and diastolic blood pressure [WMD=-4.5, (CI: -5.04 to -3.96), p=0.001], in adults with overweight and obesity. The findings of the present meta-analysis suggest 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 obesity and overweight.

Abstract
The purpose of this investigation was to determine cardiovascular risk factors in
middle-age adults male with different abdominal obesity and physical activity
levels. 40 males aged 35 to 55 years divided to four groups. Group 1
:(physically active with high WHR), group2: (physically active with low WHR),
group3: (non-active with high WHR), group 4: (non-active with low WHR).
Physical activity was assessed using beck's standardized questionnaire .Risk
factors included C-reactive proteins levels( CRP), high density lipoprotein (HDL)
cholesterol and low density lipoproteins (LDL)and total cholesterol (TC) were
assessed by taking blood samples and waist to hip ratio(WHR) determined as
an abdominal obesity index. Data analyzed using two-way ANOVA, (P≤0.05).
No significant differences were seen in risk factors included HDL, LDL and TC
levels (P≥0.05).In adults with high & low WHR, the CRP levels were
significantly different (P≤0.05)in all groups. Our data suggest that in spite of
physical activity levels, abdominal obesity is effective on CRP levels in middleaged
adults male.

Abstract
The purpose of this study was the effect of eight weeks of circuit training on the Irisin levels and
the Insulin Resistance Index (HOMA-IR) in overweight women. Materials and Methods: In this study 22
overweight women voluntarily were chosen (Age 26.04±4.43 yrs, BMI 29.35±2.53 kg/m2) and were divided
to two groups of control (n=11) and experimental (n=11). In the experimental group, subjects performed
circuit training for eight weeks and four times per week. Blood sample was taken before and 48 hours after
the last training session. Statistical analysis at the level of P<0.05 was done. Findings: After eight weeks of
training, the level of Irisin in experimental group significantly increased while the HOMA-IR had a
significant reduction (p<0.05). Also Pearson correlation co-efficiency test shows that there is a reverse
relationship between irisin and HOMA-IR (P≤0.05). Conclusion: It appears that circuit training improves
body composition and metabolic disorders such as insulin resistance through Irisin induction in overweight
women.

Abstract
Osteosarcopenic obesity is the result of processes that lead to muscle and bone breakdown and increased fat tissue. The purpose of this study was to investigate the effect of 12 weeks elastic band resistance training on functional indicators and Osteosarcopenic obesity index in women with Osteosarcopenic obesity. In this single blind randomized clinical trial, 49 elderly women with age 64.13 ± 3.6yrs, fat percentage 45.4 ± 6.56 %, T score of the minerals of the were -1.86 ± 1.42 were divided into two groups: control (n=22) and training (n = 27). The training group performed elastic band resistance training for 12 weeks. significant increases in short-term physical function (SBBP) (P = 0.024) and Z score of Osteosarcopenic obesity (P = 0.041), in the training group compared to the control group, and non-significant difference in muscle quality (MQ) (P = 0.200), fracture risk (FRAX) (P = 0.259), between exercise and control group. 12 weeks of elastic band resistance training seems to improve in short physical performance battery and Z score of Osteosarcopenic obesity in elderly women with Osteosarcopenic obesity, but, probably a longer period of training is needed to further influence the other osteosarcopenic obesity index.

Abstract
Background and objective: Effects of exercise training on metabolic disorders through modifications in fibroblast growth factor -21 (FGF-21) level are controversial. Therefore, the aim of study was to determine the quantitative effect of exercise training protocols on serum FGF-21 level in adults with metabolic disorders. Methods: A systematic search of the published Persian or English-language studies from PubMed and Google Scholar databases up to march 2021 was done and standardized mean differences (SMDs) were calculated using random-effects models. Results: a total of 14 studies (aerobic training=3, resistance training=3, HIIT=4, concurrent training=4) including on 19 interventions conducted on 503 subjects (with overweight, obesity, type 2 diabetes, metabolic syndrome and or fatty liver disease) were eligible to include in the meta-analysis. However, because of the heterogeneity, the final quantitative impact of 16 interventions was calculated as a declining serum FGF21 level after training [SMD=-0.44(CI: -0.65 to -0.22) p=0.001] which had no correlation with subjects age(p=0.10) or BMI(p=0.50) level. Conclusion: exercise training protocols are efficient tools for a remarkable decrease in serum FGF-21 in patients with metabolic disorders which seems to lead to more beneficial effects on metabolic disturbances. However, more clinical trials are still warranted in this area considering the role of exercise components such as exercise intensity and type
