Aim: The purpose of this study was to investigate the effect of 12 weeks of combined exercise on bone mineral density and some blood parameters in postmenopausal women with overweight.Materials and Methods: 29 inactive postmenopausal women with an age range of 58 to 46 years participated in this study. Subjects were placed in one of the two exercises (resistance-aerobic) and control (without exercise). Before and after the training period, weight, body mass index, fat percentage, bone density of the lumbar vertebrae and femoral head (in dexas), calcium and serum phosphorus were measured. The exercise protocol included upper and lower resistance exercises in 3 sets with 12 to 8 repetitions, and aerobic training including running and waving alternately for 12 weeks and 3 sessions per week. The data with normal distribution were analyzed using ANOVA and T-Paired methods and data without normal distribution using KruskalWallis and Wilcoxon. Finding: The experimental group showed a significant increase in serum calcium, bone density in the lumbar spine and neck (P

Background & Objectives: Cardiac rehabilitation is the most important proceeding to reduce the effects of heart surgery and its effects on cardiovascular disease. Exercise training because of low cost and being attractive can be a motivation for patients with cardiac rehabilitation programs.Exercise has influence on blood cellular components, especially the number of white blood cells, metabolism, metabolites, peptides and different type of gene expression.The aim of this study was to examine the effect of aerobic training on monocytes gene expression ABCG5 in middle-aged men after heart bypass surgery. Materials & Methods: In this semi-experimental study, 20 middle-aged malepatient who had coronary artery bypass surgery, were subjected to the study and were randomly assigned into two groups: control (N=10) and aerobic training (N = 10) groups. Blood samples were taken from subjects before and after training sessions.Monocytes isolated by centrifugation and m-RNA purified by Real-Time PCR was performed.Data were analyzed by ANOVA with repeated measures (SPSS version 16). Results: Results showed that, as a result of exercise training, there was significant increase in mRNA expression of gene ABCG5 in the experimental group than control group. Conclusion: It seems that exercise training as part of the cardiac rehabilitation in patients undergoing coronary artery bypass grafting can improve the reverse cholesterol transport process in the patients by impressing the expression of genes involved in lipid metabolism.

Abstract
Introduction: Visfatin is a newly discovered adipokine which increases with obesity. It is not clear whether endurance training which induces changes in adipose tissue and blood lipids might decrease the plasma level of visfatin as well. The aim of this study was to investigate the effect of 9 weeks of aerobic training on serum visfatin level and insulin resistance index in obese women.
Materials and methods: Method of research was semiexperimental. Twenty-eight obese female volunteered and were randomly divided into experimental (14 subjects with means of weight 82 ± 10.2 kg, and BMI 34.2 ± 4.3 kg/m2) and control (14 subjects with means of weight 79.9 ± 9.5 kg, and BMI 34 ± 3.9 kg/m2) groups. Aerobic training protocol consisted of 4 sessions per week for 9 weeks. Each training session was a slow running trial at intensity of 65 to 75 percent of maximal heart rate for a period of 15 minutes. To follow the principle of overload, half-a-minute was added to each session after the second week, so that, at the last session the running time reached to 31 minutes. Before and after the training period, blood sampling was performed. Data were analyzed using independent t test and ANCOVA.
Results: Results showed significant reduction of serum visfatin level (p < 0.05), and no significant difference in insulin resistance index, serum HDL, LDL, TC and TG between the control and experimental groups (p > 0.05). In addition, aerobic training reduced significantly body mass index, body weight, waist to hip ratio, body fat percent, and increased significantly maximum oxygen uptake (p < 0.05).
Conclusion: It can be said that 9 weeks of aerobic training can cause significant reduction of serum visfatin and no significant change in insulin resistance index in obese women.

Background: Smoking can decrease adiponectin serum and increase insulin resistance index. The purpose of present study was to examine the effect of one session of exhaustive aerobic exercise on levels of adiponectin serum and insulin resistance index in smoker men.
Materials and methods: A semi-experimental design was used. The target population consisted of smoker students of the Hakim Sabzevari University, from whom twelve smoker male students volunteered and were randomly divided into three situations; control, exhaustive aerobic exercise at 70-75% intensity of maximal heart rate, and exhaustive aerobic exercise at 90-95% intensity of maximal heart rate, in a crossover design.Two situations of aerobic exhaustive exercise programs involved running on treadmill with intensities of 70-75% and 90-95% of maximum heart rate of the subjects. During this period, the control group did not perform any physical activity. To calculate changes in plasma volume and measurement of adiponectin, glucose, insulin and lipid profile indices blood samples were collected before and immediately after performing of aerobic exercises. Data were analyzed using one way analysis of variance (ANOVA).
Results: After the correction of results with respect to plasma volume changes, no significant differences in serum of adiponectin levels (P=0.825) and insulin resistance index (P=0.756) were determined between the control and experimental situations. Furthermore, no significant difference was observed among the three situations in the glucose (P=0.633), insulin (P=0.768), low density lipoprotein (P=0.075), high density lipoprotein (P=0.131), total cholesterol (P=0.559), and serum triglyceride (P=0.641).
Conclusion: One session of exhaustive aerobic exercise with two different intensities has no effect on levels of serum adiponectin and insulin resistance index in smoker men. However, to achieve more conclusive results, further investigation is warranted.

Background: The aim of this study was to Survey of relationship physical activity level and sedentary behaviors with diet patterns among 12-14 year-old adolescent boys in Sabzevar. Materials and methods: This cross-sectional study was performed on 650 boy students aged 12-14 years in Sabzevar that were selected via classified random Sampling. Physical activity levels were assessed by the Physical Activity Questionnaire for Older Children (PAQ-C). Energy intake and Macronutrient were assessed by means of a semi-quantitative food frequency questionnaire (FFQ). Sedentary behaviors of subjects assessed by means of a made-researcher questionnaire by researcher. Data were analyzed by SPSS version 13 software using Spearman and Pearson's correlation coefficient and ANOVA test. Result: There was no significant correlation between physical activity level and energy intake and macronutrient. In total subjects there was no significant difference in the reported energy intake and macronutrient between physical activity levels. But, in 12 year-old subjects, energy intake, Total fat, Protein and Carbohydrates in low physical activity level subjects were significantly higher than moderate physical activity level subjects. There was significant positive correlation between physical activity level and Number of breakfast Consumption per week. There was no statistically significant correlation between the reported Energy intake and Macronutrient with sedentary behaviors. Conclusion: There was no significant difference in the reported Energy intake and Macronutrient between physical activity levels among 12-14 year-old students. But, energy intake and macronutrient in low physical activity level subjects were somewhat higher than active subjects. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.
