Percepção subjetiva do esforço, resposta afetiva e hipotensão pós-exercício em sessão de Tai Chi Chuan

The aim of the study was to analyze the rating of perceived exertion (RPE), affective response (AR), and blood pressure (BP) post-exercise in acute Tai Chi Chuan (TCC) session. Twenty-four women (47-79 years; 9 normotensive and 15 hypertensive) performed one TCC and one control session (cross-over design). The RPE was assessed using the Borg's scale (CR10), the AR was assessed by the Feeling Scale (+5/-5) and the BP by the oscillometric method (5, 10, 15, 20, 25, and 30min post-TCC session). A significant systolic BP reduction was observed in the 20 and 25min post-TCC session only in the hypertensive women. The AR and RPE values were +2.8 ± 1.9 e 3.5 ± 1.2, respectively. The results suggest that a moderate TCC exercise bout was pleasurable for the volunteers (normotensive and hypertensive), although it has induced a slight acute hypotensive effect on the systolic BP only in the hypertensive women.
