SUMMARY:

Introduction: The neural respiratory drive (NRD) is a strategy for assessing respiratory muscle activity to maintain pulmonary efficiency. This has been investigated in several diseases in order to understand the repercussions they impose on breathing pattern. In hypertensive individuals, there is still a gap in the literature, despite the close cardiovascular and respiratory relationship present in this dysfunction. The aim of this research was to evaluate the NRD in hypertensive during the maximum voluntary ventilation and to correlate this variable with the anthropometric data. Methods: This is a cross-sectional study with hypertensive individuals aged between 35 and 64 years, where anthropometric measurements were evaluated according to the guidelines of the International Society for the Advancement of Kinanthropometry (ISAK), maximum voluntary ventilation (MVV) and the neural respiratory drive index (iNRD), collected through surface electromyography of the second intercostal space (EMGpara). Correlations were assessed by Pearson and Spearman tests, and for the NRD comparison, Student's t-test was used, a significance level of 5% (p <0.05) was adopted. Results: 17 patients were studied with a mean BMI of 27.8 (± 2.5) kg / m2, MVV (L / min) of 104.4 (± 24.2), iNRD at rest of 1746.88 (± 531.57) UA and iNRD in the MVV of 13972.04 ± 3810.64 AU. Ventilatory capacity correlated with measurements of waist-to-hip ratio (r = -0.553; p = 0.021), waist-to-height ratio (r = -0.502; p = 0.040), taper index (r = -0.514; p = 0.035), relative fat (r = -0.612; p = 0.009) and lean mass (r = 0.612; p = 0.009). The activation of parasternal muscles was greater during MVV when compared to rest (p = 0.001), as well as iNRD (p <0.001). Conclusions: There is a greater myoelectric activity through parasternal activation during maximum voluntary ventilation and this is reflected in a higher rate of neural respiratory drive in hypertensive individuals during maximum effort, and that there is a correlation between anthropometric measures and the ventilatory capacity of these individuals.
