Combined aerobic‐anaerobic exercise seem to be a valid not pharmacological way to reduce hypertension. Circuit training (CT) is often used to train normotensive (N) and hypertensive (H) subjects, but not all the circuits are equal and some exercises could be dangerous for H. Objective of the study, conducted in accordance with Basic Principles of the Declaration of Helsinki, was: assessing the trend of blood pressure response of N and H during a CT session; defining which exercises in a CT are most safe for H; verifying the possible risks of a CT session to rise excessively blood pressure in H. Methods. 10 N and 10 H moderately trained males were enrolled. Arterial blood pressure was measured at rest and at the end of each exercise. Heart rate was recorded by a heart rate monitor. Subjects performed a 7 CT stations: bike 65–70–75% of HRmax,, leg press, leg extention, leg curl and squat. Results. Mean arterial blood pressure was significantly higher in H respect N. No difference was detected for leg‐extension and for bike 75% HRmax diastolic pressure. Leg curl, leg‐extension, leg press and bike at 65%HRmax resulted clinically safe. Bike at 70–75% HRmax and isometric squat overcame the upper limit of clinically safe exercise. Conclusions: It is necessary to monitor blood pressure during a CT programme as bike (70–75% of HRmax) and isometric squat evidenced a potential risk for H subjects.
