Behavior analysis of blood pressure in bodybuilding exercises observing the variables in two types of breathing

Abstract

The physical education professional often comes across individuals practicing resistance training (bodybuilding) in doubts about breathing during the exercise. In need of contributing scientific information on the influence of breathing on blood pressure (BP), an important imaging variable on cardiovascular health. The aim of this study was to analyze the behavior of blood pressure before and after the participation of resistance exercises, practiced with two types of breathing. Twenty-one socio-students who accepted and are in accordance with the terms of inclusion were analyzed, 9 males with a mean age of 28.1 ± 9.9 years and 12 females with a mean age of 33.4 ± 7.4 years. The equipment used for data collection: leg press 45 and horizontal bench bench. The participants were submitted to a submaximal test to verify the 1RM. They were submitted to 80% of 1 RM in the first series using active elective breaths and after recovery, the same intensity was applied to the valsalva maneuver (blocked). Systolic and diastolic blood pressure pre and post exercise with aneroid sphygmomanometer was evaluated. Systolic blood pressure (SBP) analyzed intra-group, pre and post-execution in horizontal supine increased 7.4 (5.6%) mm/Hg compared between blocked breathing (valsalva). The intra.-group result for leg press 45° exercise generated a difference of 14.3 (10.5%) mm/Hg in the same comparison. Thus, the type of breathing interferes with blood pressure during the execution of the investigated exercises, being higher for the lower segment.
