Aptidão física, indicadores de obesidade e pressão arterial de escolares de dois polos do RS : um estudo comparativo.

Abstract

The prevalence of obesity has increased dramatically over the years in Brazil. According to data from the Ministry of Health (2015), 35% of all Brazilian population are overweight and 17% are considered obese. Considering the school population aged between 5 and 9 years; 33.4% are considered overweight, already in the age group of 10 to 18 years, 23% are obese or are overweight. Obesity can lead to chronic degenerative diseases, hypercholesterolemia, increased insulin resistance, joint overload, psychological disturbances and arterial hypertension, which may impair the physical fitness of individuals. Thus, it is important that they assess the functional motor skills of children and adolescents. In this way, the main objective of this study is to verify and compare the physical fitness levels, indicators of obesity and blood pressure of schoolchildren from 7 to 17 years of age in the municipalities of Santiago and Santa Cruz do Sul, RS. The dissertation was composed of two articles: Article 1 The objective of the study was to establish a comparative analysis of the physical fitness for health and body composition of the students of the municipalities involved in the research. It was verified that students from Santiago presented levels of cardiorespiratory fitness in the zone of greatest health risk (p <0.001). The boys from Santa Cruz do Sul were in the zone of greater health risk in the flexibility test (p <0.001) and abdominal resistance (p = 0.001), as well as girls, with flexibility (p <0.001) and resistance (P = 0.002), concluding that schoolchildren from Santiago presented low levels of cardiorespiratory fitness and Santa Cruz schoolchildren presented lower levels of flexibility and abdominal resistance. Article 2: The main objective of this study was to investigate whether there are differences in the rates of obesity and arterial hypertension among students from the cities of Santa Cruz do Sul and Santiago / RS. Body mass index (BMI), waist circumference (WC), percentage of fat (% G) and blood pressure, both systolic (SBP) and diastolic (DBP) were analyzed. The mean values of PAD and SBP were significantly higher in Santiago students when compared to Santa Cruz do Sul students (p = 0.000) in both sexes, it was concluded that Santiago schoolchildren had blood pressure levels and means higher than The schoolchildren of Santa Cruz do Sul.
