Chronic conventional resistance exercise reduces blood pressure in stage 1 hypertensive men. J Strength Cond Res 25(X): 000– 000, 2011—To investigate the antihypertensive effects of conventional resistance exercise (RE) on the blood pressure (BP) of hypertensive subjects, 15 middle-aged (46 6 3 years) hypertensive volunteers, deprived of antihypertensive medication (reaching 153 6 6/93 6 2 mm Hg systolic/diastolic BP after a 6week medication washout period) were submitted to a 12-week conventional RE training program (3 sets of 12 repetitions at 60% 1 repetition maximum, 3 times a week on nonconsecutive days). Blood pressure was measured in all phases of the study (washout, training, detraining). Additionally, the plasma levels of several vasodilators or vasoconstrictors that potentially could be involved with the effects of RE on BP were evaluated pre- and posttraining. Conventional RE significantly reduced systolic, diastolic, and mean BP, respectively, by an average of 16 (p , 0.001), 12 (p , 0.01), and 13 mm Hg (p , 0.01) to prehypertensive values. There were no
