Chacon-Mikahil (PQ) Resumo The present study analyzed systolic, diastolic and mean arterial blood pressure after different strength exercise (SE, performed in leg press machine) protocols, which according to literature are efficient to increase strength and muscle mass in healthy elderly. The study was performed in a cross-over design, containing the following sessions: SEHI (80% 1RM, 4 sets with repetitions until voluntary failure), SEBFR (30% 1RM, 1 set of 30 repetitions plus 3 sets of 15 repetitions, with 50% blood flow restriction), SELO (30% 1RM, 4 sets with repetitions until voluntary failure) and control (no exercise). The data showed blood pressure variation from pre to post-exercise (5, 15 and 30 minutes) did not differ between SE sessions. Regarding these acute blood pressure variations, none of the SE protocols applied showed to be more beneficial or harmful to the cardiovascular system.
