The effect of 12 weeks of resistance training specifically designed bioelectrical impedance indices and resting blood pressure of 80 outstanding high school male athlete NGOs Tehran Region 2

Based on the life of urbanization, industrialization communities, increase economic growth and globalization of markets, rapid changes in dietary patterns and lifestyle of people (6). At least 60% of the world population that is less than the amount of physical activity they need to do for your health The reason is that leisure time physical activity generally do things that are not associated with. Of inactivity during work activities, urban civilization, the use of vehicles, lack of muscle activity fit and spend less energy reduced physical activity are leading to increasing prevalence of obesity, reduction of infectious diseases and increasing diseases related to lifestyle among people been Since the 1990s, physical inactivity as one of the main risk factors for cardiovascular disease in adults and young people, has been developed (19). Overweight and obesity are a major cause of many diseases, including cardiovascular disease, hypertension, diabetes and cancer Today, obesity has emerged as a global crisis (37) and in many countries as well as families to reduce the prevalence of obesity and related diseases is Baan costs (8). Surveys and studies have shown that in developed countries 25% of children 6 to 14 years opt expansion in the range between 11 and 29% are overweight Overweight and obesity among children and adolescents in the country also has a growing trend and its relationship with lifestyle including lack of exercise has been shown Hypertension is the most important complications of obesity and overweight is one of the world s health problems That is why the disease is considered a cause of global challenge that the 2013 World slogan of the World Health Organization 1 (WHO) issue (hypertension) is (37). Lamvnth 2 states that the diastolic blood pressure higher than in the sedentary group is active Experts suggest that blood pressure is twice the overweight young and in the elderly 50% more than people with normal weight (154). Thus it is possible that children with high blood pressure, decreased cardiorespiratory fitness 😔CRF), as a risk factor of cardiovascular complications in the future will be very large On this basis, and given the importance of the prevention of hypertension, the need to identify people with early problems and considerations developed in order to improve physical activity in children and adolescents and prevent the rise of childhood obesity seems to be important This study aimed to evaluate blood pressure and to determine its relationship with anthropometric indices (bioelectrical impedance) among adolescents with the goal of reducing it by 12 weeks of resistance training is done
