This is a parallel, randomized controlled trial. 125 nonconsecutive sedentary patients with resistant
hypertension from a hypertension outpatient clinic in a university hospital were screened; 32 patients fulfilled
the study requirements. The training was performed for 60-minute sessions in a heated pool (32 °C), three
times a week for 12 weeks. The HEx protocol consisted of callisthenic exercises and walking inside the pool.
The control group was asked to maintain habitual activities. The main outcome measure was change in mean
24-hour ambulatory BP (ABPM).
