Effects of Exercise Mode on Cardiac Fat and Function

September 27, 2021 updated by: Southern Illinois University Edwardsville
The overall goal of this project is to study the effects of exercise energy expenditure matched vigorous dynamic resistance training and aerobic training on cardiac fat, and its relationship to cardiac function and geometry using cardiac Magnetic Resonance Imaging.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Exercise-induced weight-loss is one of the most common strategies for reducing excess fat in overweight and obese individuals. Although vigorous intensity may be more favorable promoting positive cardiac adaptations compared to low-moderate intensity, evidence of the positive effects of different exercise modes needs to be explored to allow for realistic comparisons with other strategies. Research using cardiac Magnetic Resonance Imaging that compares the effects of different modes of exercise - matched by exercise energy expenditure - on epicardial adipose tissue and paracardial adipose tissue, and how these interventions modify cardiac function and geometry have not been previously explored in obesity.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control group
Participants in the control group will not participate in the training programs.
Experimental: Resistance training group
Resistance training will consist of a supervised circuit training 3 sessions/week for approximately 45-50 min/session. The circuit will include 7 strength exercises engaging the major muscle groups (leg press, rows, back squats, weighted crunches, deadlifts, bench press, and squat jumps with weights). The participants will perform 3 sets of 10 repetitions with resting periods of 30 seconds between exercises, and 2 minutes between sets. The overall OMNI-Resistance Exercise Scale per set will range between 8-10. Heart rate and exercise energy expenditure during the workout will be monitored. The load will be changed depending on the participants' perception when needed. In addition, the intensity will be monitored assessing Lactate concentrations at baseline and at the end of each session. Circuit will be repeated until meeting the targeted exercise energy expenditure of 450-500 kcal/session.
Other: Resistance training
The resistance training group
Experimental: Aerobic interval training group
Aerobic interval will consist of a supervised aerobic interval training sessions 3 times/week. Duration will range between 45-50 min/session depending on the exercise energy expenditure. Each interval will have a total duration of 5 min, and it will be divided into 2 periods. The first period will consist of 3 minutes of high-intensity activity, and the second period the intensity will be reduced for 2 minutes. The speed/incline will be changed depending on the participants' heart rate and perception using the Borg's rating of perceived exertion as needed. Heart rate and exercise energy expenditure during the workout will be monitored. Intensity will be monitored assessing Lactate concentrations at the end of each session. Intervals will be repeated until meeting the targeted exercise energy expenditure (450-500 kcal/session).
Other: Aerobic interval training
