Introduction: In the present study, the effect of two types of resistance training - traditional and EMS on the levels of iris, glucose, insulin and insulin resistance in Inactive middle-aged womenwas compared.Material and Method: The study population consisted of 45 elderly women in Rasht with mean age (44.46 ± 3.42 years), weight (79 ± 7.89 kg), body mass index (34.4 ± 3.94 kg / height) and fat percentage (39.95 ± 4.50), which were randomly divided into three equal groups: 1) resistance-traditional (n = 15), 2) EMS (n = 15) and 3) control (n = 15) Were divided.After evaluating the anthropometric indices, the training groups performed their own training intervention for eight weeks.Results: The results of data analysis showed that the levels of irisin in the post-test compared to the pre-test showed a significant increase in both resistance-traditional and EMS training groups (P ≤ 0.05), which was higher in the EMS training group. (P≤ 05/0).Insulin and glucose levels and insulin resistance index also decreased significantly in post-test compared to pre-test in both training groups compared to control (P ≤ 0.05). While there was no significant difference between training groups (P ≥ 0.05).Conclusion: According to the results, it can be said that both traditional resistance training and EMS improved glucose metabolism and insulin resistance index in Inactive middle-aged womenby increasing irisin levels.

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.

Objective: Neutrophils contain myeloperoxidase enzyme, which is involved in many cellular processes by producing oxidants and catalyzing hypochlorous acid. On the other hand, from middle age, physiological protection against oxidative stress starts to decrease. Therefore, the main purpose of this study was to determine myeloperoxidase and total oxidative status changes in healthy trained middle-aged men participating in regular recreational exercise training and untrained subjects.Methodology: 20 trained (age 53.85±2.94, BMI 25.47±1.6, VO2max 42.38±2.8) and 17 untrained (age 54.17±2.83, BMI 27.83±1.12, VO2max 31.86±1.67) subjects participated in the study. Subjects performed a modified Bruce treadmill test as a model of progressive exercise training. Blood samples were taken before (T0), immediately after (T1) and one hour after the end of the test (T2).Results: There was no significant changes in pretest myeloperoxidase level in both groups, but these values were significantly changed in untrained group compared to the trained group at T1 and T2. Total oxidant status levels in both groups increased significantly after completing the test compared to the pretest. Conclusion: Regular participation in recreational exercise training can reduce the level of myeloperoxidase and total oxidative capacity of healthy middle-aged men, and may be a proper way to have a healthy lifestyle along with reduced immune system and oxidative stress markers caused by aging in middle-aged men.

Aim: The purpose of this study was to investigate the effects of aerobic exercise on leptin and testosterone in obese boys’ serum at different pubertal stages. Method: The cross-sectional study had a pre-test- post-test design. The subjects included 36 obese boys aged 12 to 17 years, who according to the Tanner index, were in the stage of puberty of TS2 to TS5. The subjects were divided in to two groups, TS2, 3 (n=19, age: 13.4±0.94 years, Weight: 76.61±16.7 kg, BMI: 29.41±5.22 kg/m2) and TS4, 5 (n=17, age: 14.9±1.48 years, Weight: 93.57±16.48 kg, BMI: 30.92±3.88 kg/m2), each divided into aerobic exercise and control groups. After anthropometric measurements, fasting serum’s leptin and testosterone levels were measured. The aerobic exercise group completed 12 weeks of running, three times a week 30 minutes on average with an intensity of 60 to 85 percent of maximum heart rate. A pedometer was used to measure the level of physical activity and N4 software was used for measurement of energy intake. The statistical t-test, one-way and two-way ANOVA was used to analyze the data. Results: Lean body mass increased and body fat percent decreased significantly in aerobic exercise group at both stages of puberty (P≤0.05). In aerobic exercise group decrease in BMI and body fat, was only significant in TS4, 5 (P≤0.05). serum leptin levels decreased at different stages of puberty and was at only significant in aerobic exercise group (P≤0.05); but its changes in aerobic exercise and control groups at each stage of puberty wasn’t significant. Analysis of variance showed that puberty affects leptin changes (P≤0.05) but there was no significant difference between the effect of aerobic exercise on leptin decrease and changes in testosterone in both groups (TS4, 5 and TS2, 3 ) Conclusion: The results indicated that aerobic exercise in obese adolescent boys can lead to favorable changes in body composition, along with decreased serum’s leptin. However, part of these changes result from the normal maturation process that can lead to different responses to aerobic training, though due to the low number of subjects showing it about serum’s leptin, was not possible.
