About this study

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

A quasi-experimental study developed in sedentary morbidly obese men and women (age 43.6±11.3 y; body mass index [BMI] ≥40 kg/m2) were assigned to a CT group of ET plus RT (ET+RT; n=19; BMI 47.8±16.7) or RT plus ET order group (RT+ET; n=17; BMI 43.0±8.0). Subjects of both groups received eight exercise sessions over four weeks. Systolic (SBP), diastolic (DBP), mean arterial pressure [MAP], heart rate at rest [HR], and pulse pressure [PP] measurements before and after 10 minutes postexercise. Secondary outcomes were other anthropometric, body composition, metabolic, and physical condition parameters. Using the ∆SBP reduction, and quartile categorization (Q) in 'high' (Rs: quartile 4), 'moderate' (MRs: quartile 3), 'low' (LRs: quartile 2), and 'nonresponders' (NRs: quartile 1) were reported.

Read the detailed description

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.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Chile. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Systolic blood pressure measured by a blood pressure cuff (time frame: From baseline to 10 minutes after exercise training). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05504629, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Aug 2022.
