Overview

Both high and low intensity resistance training elicit acute post-exercise hypotension in pharmacologically treated hypertensive adults, with autonomic modulation playing a key role in the blood pressure reduction.

Key Points

  • This research aims to explore how cardiac autonomic responses to different resistance training intensities affect blood pressure in hypertensive individuals.
  • Randomized clinical trial with 31 adults treated for hypertension.
  • Compared high intensity (80% of 1RM) and low intensity (40% of 1RM) resistance training.
  • Measured blood pressure and heart rate variability before and after each exercise session.
  • Both intensity levels significantly reduced blood pressure and cardiac parasympathetic indices.
  • In high intensity training, heart rate variability was positively correlated with blood pressure reduction.
  • Low intensity training showed a negative correlation between low frequency heart rate variability and blood pressure.
