Perfil hemodinâmico e nível de atividade física de professores do Ensino Médio da Rede Pública de São João dos Patos - MA

Abstract

This study aimed to analyze the hemodynamic parameters and physical activity level of high school teachers in the public school system of São João dos Patos – MA. It was a cross-sectional, quantitative, and descriptive field study conducted with 40 teachers, 17 men (43%) and 23 women (57%), from three educational institutions in the municipality. Sociodemographic and anthropometric data, physical activity level using the International Physical Activity Questionnaire (IPAQ), and hemodynamic variables such as blood pressure (BP), heart rate (HR), heart rate variability (HRV), mean arterial pressure (MAP), double product (DP), and oxygen saturation (SaO2) were evaluated. Handgrip strength and cardiorespiratory fitness tests using the McArdle bench protocol were also performed. The results indicated that the general HRV parameters presented adequate values; however, there was a significant difference between the sexes in the LF and LF/HF variables, demonstrating a greater sympathetic predominance in men. Regarding physical activity levels, men showed a higher prevalence of active and very active individuals, while women showed a higher percentage of insufficiently active individuals, with a statistically significant difference between the groups. In blood pressure classification, women showed a higher frequency of optimal blood pressure, while men had higher values for pre-hypertension and stage 1 hypertension, although without significant differences. In physical tests, most participants presented normal handgrip strength, with no differences between the sexes. In the McArdle bench test, men showed a higher frequency in the excellent classification, also without significant differences. Regarding hemodynamic parameters, only SaO2 showed a significant difference between men and women, with higher values in females. MAP and double product did not show significant differences. It is concluded that the evaluated teachers presented satisfactory cardiovascular conditions, however, men demonstrated less favorable indicators related to cardiac autonomic modulation and blood pressure profile. These findings reinforce the importance of health promotion strategies and encouragement of regular physical activity in this population.
