Aim: It seems that exercise training may have benefits for improving metabolic syndrome and obesity. However, there are limited documents in effect of water-based rhythmic exercise training and the menopause population. Therefore, the aim of this study was to determine the effect of water-based rhythmic exercise training on leptin, aldosterone and blood pressure in obese postmenopausal women with metabolic syndrome.Method: This study was a clinical trial performed on 31 obese and postmenopausal women aged 65-75 years with metabolic syndrome (15 in the control group and 16 in the experimental group). The participants were randomly allocated into control and experimental groups. The experimental group performed that water-based rhythmic exercise training for 12 weeks, three sessions per week and 60 minutes per session. Leptin, aldosterone and blood pressure were measured before and after the end of the intervention period in both groups. Data were analyzed using independent t – test and Covariance by SPSS software version 16.Results: Twelve weeks water-based rhythmic exercise training significantly reduced leptin (P = 0.001), aldosterone (P = 0.001), systolic blood pressure (P = 0.001) and diastolic blood pressure (P = 0.031) in obese postmenopausal women with metabolic syndrome.Conclusion: It seems that water-based rhythmic exercise training have a positive effect on leptin, aldosterone and blood pressure on Obese postmenopausal women with metabolic syndrome.Keywords: leptin, aldosterone, blood pressure and water-based rhythmic exercise training.

The aim of this study was to evaluate the effect of aerobic resistance training on the growth of muscle fibers, testosterone and androgen receptors in male rats of different age groups. 30 male Wistar rats, child (n=10), young (n=10) and elderly (n=10), were divided into two groups of training and control Exercise were performed intermittently, one day for resistance and one day for aerobic for 6 weeks. 48 hours after the last training session, anesthesia, blood sampling and then were killed and then gastrocnemius and soleus muscles were extracted. Blood serum was also isolated and then blood testosterone was measured by ELISA, muscle growth was measured by light microscopy and gene expression of androgen receptors was measured using Real-time pcr. The results showed that the cross- sectional of muscle fiber in all three training groups of ages contains: child (p=0.001), young (p=0.003) and elderly (p=0.001) were more than control groups. There were no significant difference in serum testosterone between training and control groups of child (p=0.6), while serum testosterone in young (p=0.008) and elderly (p=0.001) training groups were more than controls. Also there were no significant difference in expression of androgen receptors between training and control groups of child (p=0.3), young (p=0.3) and elderly (p=0.8). The results showed that resistance-aerobic exercise can cause muscle hypertrophy at different ages by increasing testosterone concentration. Resistance-aerobic training can accelerate the growth process and also prevent muscle atrophy in old age.

Background: This study aimed to investigate the effect of caffeine and carbohydrate co-ingestion on anaerobic performance and muscular strength of female wushu athletes. Methods: 7 female wushu athletes with 22.00 ± 6.11 years of age, 52.96 ± 4.87 kg weight and 161.29 ± 5.28 cm height participated in 1RM leg and bench press and RAST tests on 4 occasions separated by 1-week washout after accidental consumption of caffeine (6 mg/kg in 250 mL water), 8% carbohydrate (21 g in 250 mL water), caffeine+carbohydrate and placebo. Data were analyzed by repeated measure ANOVA and Bonferroni tests in SPSS26, α = 0.05).Results: caffeine alone did not affect variables (P ≥ 0.05). Carbohydrate consumption increased 1RM bench press ⁓7% (P = 0.010) and 1RM leg press ⁓16% (P = 0.033). co-ingestion of carbohydrate and caffeine improved mean power ⁓15% (P = 0.027), 1RM bench press ⁓26% (P = 0.005) and leg press ⁓39% (P = 0.027). Conclusion: it seems, that carbohydrate has more effect on strength than caffeine, but combined with caffeine it may improve mean power besides the muscular strength in female wushu athletes due to effects on the central nervous system and increasing carbohydrate effect.

Aim: The purpose of the study was to investigate the effect of 8 weeks of aerobic interval exercise with silymarin supplementation on antioxidant, liver damage and atherogenic indicators in male Wistar rats fed a high-fat diet.Methods: This experimental study with laboratory method was performed on 35 male Wistar rats with a body weight of 160.45±7.08g and 3-weeks-of-age were randomly divided into 5 groups consisted of ordinary diet control (ODC), fatty diet control (FDC), fatty diet with supplement (FDS), fatty diet with exercise (FDE), fatty diet with supplement and exercise (FDSE). The exercises included the running on treadmill for 8 weeks, five times/week and 30 minutes in an exercise session. Silymarin supplementation with dose of 140 mg/kg/day of body, weight was received for two weeks. Liver tissue and samples were obtained after 48 hours of the last diet and data analyzed. Results: Significant decrease in FDSE and FDE groups compared with FDC group in ALT, AST, and ALP, MDA, TC and TG variables were observed. Whereas, there were significantly increased in FDSE group compared with FDC in SOD and HDL-C variables. Also, LDL-C and AIP in FDSE group compared with FDC had shown a significant decrease (p> .05).Conclusion: The applying of aerobic interval exercise alone or with silymarin supplementation reduced the risk to NAFLD such as enzymes involved and atherogenic index in male Wistar rats fed a high-fat diet; therefore, it could probably improve the disease through increase the antioxidant capacity and reduce blood lipid profiles.

Aim: Converting white adipose tissue (WAT) to brown adipose tissue (BAT) is therapeutic potential to combat obesity. The purpose of this study was to investigate the effects of aerobic training and capsaicin (Cap) on FNDC5 gene expression and irisin protein level of visceral adipose tissue in rat fed a high-fat diet (HFD).Methods: 40 male Wistar rats were fed a normal diet (ND, n = 8) or HFD (n = 32) for 8 weeks. After 8 weeks, all rats were divided into 5 groups: ND, HFD, high-fat diet-training (HFDT), high-fat diet-capsaicin (HFDCap), high-fat diet-training-capsaicin (HFDTCap). Training groups have performed a progressive aerobic running program (at 15-25 m/min, 30-60 min/day, and 5 days/week) on a motor-driven treadmill for eight weeks. Capsaicin (4 mg/kg/day) were administered orally, by gavage, once a day. Results: The results of this study showed that FNDC5 expression (p=0.001) and irisin (p=0.000) was decreased in HFD group compared to ND group. Also, the expression of FNDC5 and irisin in HFDT (Respectively p=0.006, p=0.020), HFDCap (Respectively p=0.005, p=0.021) and HFDTCap (Respectively p=0.000, p=0.000) groups was significantly increased compared to HFD. The expression of FNDC5 and irisin in HFDTCap was also significantly increased compared to HFDT (Respectively p=0.037, p=0.035) and HFDCap (Respectively p=0.044, p=0.033) groups.Conclusions: Aerobic training combination with capsaicin with increased FNDC5 and irisin in visceral adipose tissue, had Interactive effects on factors affecting browning of adipose tissue.

The purpose of this study was to investigate the effect of eight weeks high intensity interval training and spirulina supplementation on humoral immune system, cardio respiratory fitness and body composition of overweight women. 30 inactive students (height (cm): 161. 7 ± 2. 8, weight (kg): 75.76 ± 8.43, age(y): 25. 06 ± 6. 66) were divided into three groups (placebo - HIIT, spirulina - HIIT, spirulina). Exercise groups performed HIIT for 8 weeks (3 sessions per week with 4-7 repetitions in each session () in intensity of 90% of the maximum heart rate). Supplementation groups received 6 g spirulina powder per day. Fasting blood samples were collected before and after 8 weeks to determine the levels of IgA and IgG. A significant reduction was observed in BMI, WHR, body fat percentage and significant increase in body fat free mass, VO2max, IgA in all three groups. There was a significant elevation in IgG level in the placebo - HIIT and spirulina - HIIT (P=0. 001, t=-6. 77) groups. However, there was no significant difference in IgG levels between the pre and post supplement consumption in the spirulina group (P=0. 07, t=-1. 54). In general, the results of this study showed that 8 weeks of HIIT and supplementation of spirulina increase the function of the immune system and respiratory cardiovascular fitness. Also, 8 weeks of HIIT and spirulina supplementation cause of weight loss and increase fitness by decreasing BMI, WHR, body fat percentage and increase body fat free mass in women.
