Resposta hemodinâmica aguda às aulas de Cycling, Jump e Mat Pilates em adultos ativos

Abstract

Introduction: The progressive increase in blood pressure values is a growing concern in society, contributing to the increased risk of developing cardiovascular diseases, including hypertension. In Portugal, data from the National Institute of Statistics (INE) indicate a prevalence of hypertension in the adult population of approximately 43%, which has a significant impact on public health. Objective: This study aimed to analyze the acute effect of different group classes on the hemodynamic response of active adults and to compare their responses. Methodology: A hemodynamic analysis was conducted with a sample of 100 participants of both sexes, 63% feminine and 37% masculine, aged between 25 and 65 years, during three classes: jump, Schwinn Indoor Cycling, and Pilates. The assessment of parameters was conducted at four time points: rest, pre-class, post-class, and 15 minutes after class, using an OMRON M2 - HEM-7121-E automatic sphygmomanometer. Results: The results revealed a significant time effect on systolic blood pressure (p<0,001), mean arterial pressure (p<0,001), and heart rate (p<0,001), as well as a significant interaction between class and time for these same variables (p<0,001; p=0,003; p<0,001). No significant effect of the different classes was observed. Regarding diastolic blood pressure, the results did not show significant differences either over time (p=0,124) or between the classes (p=0,342). Conclusion: The differences in hemodynamic responses reflect the intensities and specific characteristics of each class. The results indicate changes over time in systolic blood pressure, mean arterial pressure, and heart rate; however, the variation observed was not solely associated with the type of class attended. Jump and cycling demonstrated more significant responses, with reductions of 9.5% and 8.6%, respectively, from the pre-class moment to 15 minutes post-class, while Pilates showed a reduction of 3.2%.
