OBJECTIVE The purpose of the present study was to evaluate the acute effects of single session of body-weight resistance exercises on blood pressure (BP) and glycemia in middle-aged adults with hypertension. METHODS Twenty-three participants took part in this trial with crossover design and performed two experimental sessions in a random order: Body-weight resistance exercise session (BWR) and a control session without exercise. BWR was composed of four exercises: inverted row, squat, , and sit-ups. The participants performed 3 sets of 30 s, in which they were instructed to perform as much repetitions as possible and as fast as possible. After each session, BP and glycemia were measured continuously for 60 min. RESULTS Systolic BP decreased after BWR when compared with control at post 45': -7 (95%CI:-11 to -2) mmHg, p = .003 and post60': -7 (95%CI:-12 to -3) mmHg, p = .003. Diastolic BP decreased after BWR when compared with control at post 15': -6 (95%CI:-9 to -3) mmHg, p < .001; post 30': -6 (95%CI:-9 to -2) mmHg, p = .001; post45': -5 (95%CI:-9 to -2) mmHg, p = .005; and post60': -6 (95%CI: -8 to -3) mmHg, p < .001. No significant difference was found in glycemia between BWR and control sessions. CONCLUSION BWR acutely reduces BP in middle-aged adults with hypertension without effects on usual glycemia responses. This alternative form of resistance training could facilitate access, adherence, and reduce health costs related to exercise programs.
