Introduction: Regular physical activity is recommended in patients with arterial hypertension as part of the necessary lifestyle modifications. Aim of the study: The aim of the study was to assess the possibility of increasing the physical activity of patients with resistant hypertension. Material and methods: The study group consisted of 27 patients meeting the diagnosis criteria of resistant hypertension and 26 patients with well-controlled hypertension, as a control group. Anthropometric and bioimpedance-based body composition measurements were performed three times within the course of the 6-month-long study, at baseline and after 3 and 6 months, and a physical activity profile was determined based on the International Physical Activity Questionnaire. The study also included accelerometer measurements conducted for 72 consecutive hours. The participants were recommended to perform regular aerobic physical activity, chosen individually during meetings with the study scientist, in accordance with the guidelines of the American Heart Association. Moreover, the patients were motivated to perform physical activity with short text messages and phone calls. Results: A significant change in the resistant hypertensives was observed after 6 months, regarding the number of steps taken (17,361 ± 6,815 vs. 23,067 ± 7,741; p < 0.005), metabolic equivalent of task (1.325 ± 0.3 vs. 1.464 ± 0.3; p = 0.001), duration of rest (1,595 ± 265 vs. 1,458 ± 292 min; p < 0.05) and sleep (1,278 ± 228 vs. 1,147 ± 270 min; p = 0.02), as assessed based on 3-day accelerometer measurements. An increase in activity was also observed based on the International Physical Activity Questionnaire and positive changes in body composition were determined. Conclusions: In the case of patients with resistant hypertension, intensification of physical activity is a well-tolerated, implementable and cost-effective therapeutic intervention.
