Characterizing The Interindividual Postexercise Hypotension Response For Two Order of Concurrent Training In Patients With Morbid Obesity

Independent of the order (i.e., ET+RT, or RT+ET), each CT session had two sections; RT and ET, which were applied two days per week, during 8 sessions (4 weeks), and where the blood pressure changes were measured only in four opportunities (i.e., once a week in sessions 2, 4, 6, and 8). Thus, the CT included in each session 3 stages; a) callisthenics exercises, b) main exercise (ET+RT or RT+ET), and c) cool down exercises.

Before the starting, the participants were involved in the maximum strength capacity estimated using a submaximal test based on the Brzycki's equation: weight [1.0278-(0.0278*repetitions)] that does not change based on the sex, age of the population, or the exercise modality that is performed (Mayhew et al., 2004). After this procedure, there were applied 4 familiarization sessions that consisted in; session 1: 'knowledge of all measurements', 'knowledge of exercise-machine manipulation', and 'instructions during the exercise program', session 2: 'exercising during cycling', 'weights, and metal bars', session 3: 'applying a few of exercises of RT in 2 to 3 sets of exercises, to know the configuration of each exercise (i.e., ET and RT regimes itself), and session 4: 'applying the 50 to 70% of their CT program' corresponding to a normal session compound. In the 'calisthenic stage', each subject developed 10 minute warm-up with continuous walking, joint mobility and flexibility exercises. In the 'main part' of the session, and independent of the CT order group (ET+RT or RT+ET), the ET section consisted of continuous cycling using a magnetic resistance static bicycle (OxfordTM Fitness, model BE-2701, Chile) for 20 minutes. The intensity of the ET exercise was regulated through the previously used modified Borg scale from 1 to 10 rating of perceived exertion (Gillen et al., 2013) and the participants worked at a level between 5 to 7 points (i.e., moderate-intensity), considering the original 6 to 20 points scale (Borg, 1998), being the subjects regularly controlled to not exceed this intensity restriction. On the other hand, the RT section included 8 to 12 muscle strength exercises of circuit training with the following different muscle groups: (1) forearm, (2) knee flexors and extensors, (3) trunk, (4) chest, (5) shoulder elevators, (6) horizontal shoulder flexors, (7) extensors, and finally (8) plantar flexors. These exercises were performed in one set in a continuous concentric/eccentric voluntary contraction as possible for 60 seconds, followed by 60 to 90 seconds of passive recovery, where each participant was changed to another exercise. The RT section was of 25 minutes in duration time.
