Abstarct: Increase in leisure physical activity factors with respect to intensity, duration, continuity and reduce the risk of mextabolic syndrome exist. The aim of this study was to investigate the prevalence of mextabolic syndrome and its association with body composition in men aged 45 to 80 years participating in the exercise in the morning was the Shahrood city. The research sampling has been targeted for sampling. A total of 80 men volunteered to participate in the study. People who have at least 3 days a week in the past 3 years participated in the exercise in the morning, and people were selected for data on physical activity, body and biochemical assessment was not recorded were excluded. Eventually, 55 men with a mean age (61/27± 8/05) were included. Demographic information (age, smoking, educational status and history of drug use, etc.) and the amount of physical activity by questionnaire on demographic and dietary data were collected by questionnaire FFG. After measuring the body mass index (body weight, body fat mass, body fat percentage, body mass net (LBM), body mass index (BMI)), blood factors, blood pressure, waist circumference (WC) the ratio of waist to hip ratio (WHR) were measured. Data analysis was performed using spss software version 21. KS test was used for normal data and correlation between body composition indicators of mextabolic syndrome and Pearson's correlation coefficient was calculated. The results show that 23.7% of study, mextabolic syndrome was observed that the effect of physical activity is decreased. The results of the relationship between mextabolic syndrome indicators of body composition, blood pressure, body composition associated with any of the indicators showed Mnadray and fasting glucose was only Mnadra body weight. However, the triglycerides in addition to body weight and BMI, waist circumference and body mass Mnadra the net. HDL serum levels also showed a significant negative correlation with body weight and waist circumference was the only indicator of mextabolic syndrome was associated with all measures of body composition. The relationship between body weight and mextabolic syndrome parameters were observed. It can be concluded that the company Morning exercise improves body composition and markers of mextabolic syndrome and mextabolic syndrome reduces. Due to the weight of the present study showed that the most relevant indicators of the mextabolic syndrome is recommended. In addition to studies in waist circumference and BMI, body weight also breeds and ages to identify risk factors in the measure.
