Physical Exercise in Postoperative Bariatric Surgery Patients

Universidad Católica del Maule75 enrolled

Overview

This study aims to determine the effect of two types of exercise training on body composition, cardiopulmonary function and quality of life in people after undergoing bariatric surgery.

Three groups will be studied: 1. Control group (CG) 2. Group of moderate intensity continuous aerobic exercise (GMICT) 3. High intensity interval aerobic exercise group (GHIIT) The CG will follow the usual protocol adopted by the hospital San Juan de Dios, Curicó, Chile. The protocol consists in delivering information about relevance of engage in regular physical exercise practice according to the World Health Organization (150 minutes of activity per week moderate physical or at least 75 minutes of intense physical activity), but do not include the patients in a supervised physical exercise program. The GMICT will undergo a physical exercise program in which the aerobic component will be a moderate-intensity continuous exercise training (60% of the heart rate reserve). The GHIIT will undergo the same exercise program of the GMICT, but the aerobic component will be a high-intensity interval exercise training (10 sets of 1 min at 90% of heart rate reserve, with 1 min of rest between sets). All groups will receive a nutritional diet plan prescribed by a specialist bariatric nutritionist blinded to the participants group assignment. At the end of the study, the CG will be invited to enjoy the exercise program showing to be more effective. Outcomes will be assessed at four time points: 1) one week before surgery; 2) 21 days after surgery (baseline before start exercise program); 3) 8 weeks after the beginning of the exercise program; and 4) one week after the end of intervention. Main outcomes are: 1) body composition; 2) heart rate variability; 3) six-minute walk test and 4) quality of life. Secondary outcomes will be: 1) maximal respiratory pressures; 2) flowmeter; 3) dynamometry of upper limb; and 4) squat test in 30 seconds. All procedures will be performed in the Hospital of Curicó, Chile, at the Department of Physical Medicine and Rehabilitation Service.

Inclusion Criteria: * Persons between 18 and 65 years old, both sexes, who have undergone bariatric surgery, with medical authorization to perform physical exercise, that the wound healing process operative is in the final phase, which have been administered with subsequent anti thrombus treatment to surgery, who have no plans to change their place of residence within the current year. Exclusion Criteria: * Persons who have had immediate complications after bariatric surgery (dehiscence anastomosis and operative wound dehiscence), presented any comorbidity decompensation after surgery, who are in the process of dialysis or who suffer from neuromotor disease.

Outcomes

Primary Outcomes

Body fat (%)

To determine the effects of HIIT and MCIT on body composition by measuring percent of body fat using a tetrapolar bioelectrical impedance.

Time frame: 16 weeks

Muscle mass (Kg)

To determine the effects of HIIT and MCIT on body composition by measuring muscle mass using a tetrapolar bioelectrical impedance.

Time frame: 16 weeks

Bone mass (Kg)

To determine the effects of HIIT and MCIT on body composition by measuring bone mass using a tetrapolar bioelectrical impedance.

Time frame: 16 weeks

Heart rate variability

To determine the effects of HIIT and MCIT on cardiac autonomic control in supine and orthostatic positions.

Time frame: 16 weeks

Six minutes walk test (mts traveled)

To determine the effects of HIIT and MCIT on functional capacity using the six-minute walk test.

Time frame: 16 weeks

Moorehead-Ardelt Quality of Life Questionnaire (MAQ II)

To determine the effects of HIIT and MCIT on quality of life by the Moorehead-Ardelt Quality of Life Questionnaire. The score of each answer ranges from -0.5 (most unfavorable situation) to +0.5 (most favorable situation). According to the score obtained: -3 to -2.1: "very poor"; -2 to -1.1: "poor"; -1 to 1: "fair"; 1.1 to 2: "good"; and 2.1 to 3: "very good" quality of life.

Time frame: 16 weeks

Bariatric Analysis and Reporting Outcomes System (BAROS Score)

To determine the effects of HIIT and MCIT on quality of life by the Bariatric Analysis and Reporting Outcomes System. Moorehead-Ardelt questionnaire incorporates the percentage of overweight lost or gained after surgery, resolution of comorbidities associated with morbid obesity, need for reoperation and complications. According to the score obtained, it is categorized as: ≤1: "failure"; \> 1 to 3: "fair"; \> 3 to 5: "good"; \> 5 to 7: "very good"; and \> 7 to 9: excellent.
