Relação do sedentarismo e do tempo de prática de exercício físico com a pressão intracraniana

Abstract

When evaluating intracranial pressure (ICP), P1 is formed by the systolic wave and P2 by the dispersion of cerebral fluids. ICP morphology is considered normal when P1 is greater than P2, resulting in a P2/P1 ratio less than 1. Although ICP is influenced by blood pressure (BP), few studies have evaluated the relationship between BP and risk factors (RR ) modify it, such as physical exercise (PE), in the morphology of ICP. The objective of this study was to verify the association of sedentary lifestyle and the correlation of weekly time spent practicing PE with ICP. Analytical cross-sectional study that evaluated personal data, body mass index (BMI), presence of diabetes, smoking and alcohol consumption, the practice of PE and casual measurements of BP and non-invasive ICP (brain4care) of people over 18 years of age and without use of antihypertensives. Descriptive analysis, comparison with chi-square test and correlation (Spearman test) were performed. P < 0.05 was adopted. 32 participants were evaluated, 78.1% men, mean age 43.8±18.6 years. The practice of PE was reported by 62.5% with a weekly duration of 224 (120-300) min/week. 37.5% were identified as sedentary, with no difference between gender, marital status and presence of diabetes, smoking, alcoholism and obesity. No difference was identified in the P2/P1 ratio between sedentary (1.18±0.394) and active (1.09±0.252) nor any correlation between weekly PE time and P2/P1. We concluded that the P2/P1 ratio in the studied sample was not related to sedentary lifestyle or weekly PE time.
