Effects of Concurrent Aerobic and Resistance Training After Bariatric Surgery in Women: RCT

Gazi University20 enrolled

Overview

The purpose of this study is to evaluate the effects of a 12-week exercise program on body composition and various physical and physiological parameters in patients who have undergone bariatric surgery. The exercise interventions include aerobic training and combined aerobic and resistance (strength) training. The study aims to determine the impact of these exercise approaches on post-operative recovery and overall physical fitness in this population.

Objectives and Methods: This study aimed to investigate the effects of a 12-week structured exercise program on body composition and selected physical and physiological parameters in female patients who had undergone bariatric surgery. A total of twenty women who had received sleeve gastrectomy and were in the early post-operative period (third month after surgery) were included in the study. Participants engaged in supervised exercise interventions consisting of aerobic training as well as combined aerobic and resistance (strength) training protocols, designed in accordance with standard exercise prescription principles. The exercise programs were implemented over a 12-week period with regular monitoring to ensure adherence and safety. Anthropometric measurements, including body weight, body mass index, and waist-to-hip ratio, were obtained using standardized procedures. Body composition parameters such as body fat percentage, regional fat distribution, lean body mass, and basal metabolic rate were assessed using appropriate measurement techniques. In addition, selected biochemical parameters, including markers related to metabolic health, were evaluated through blood analyses. All measurements were conducted at baseline and repeated at the end of the 12-week intervention period under consistent conditions to ensure reliability and comparability of the data.

Interventions

AerobicexerciseBEHAVIORAL

The aerobic exercise intervention is a supervised 12-week program conducted 3 sessions per week. Each session lasts approximately 45-60 minutes and consists of: 1) A 5-10 minute warm-up period at low intensity, 2) 30-40 minutes of moderate-intensity aerobic activity (treadmill walking or stationary cycling) targeted at 60-70% of the heart rate reserve (HRR), and 3) A 5-10 minute cool-down period. Exercise intensity is continuously monitored using heart rate monitors to ensure compliance and adherence to the prescribed intensity zones.

Resistance TrainingBEHAVIORAL

Supervised resistance training including 2-3 sets of 8-12 repetitions at 60-80% of 1RM targeting major muscle groups

Outcomes

Primary Outcomes

Change in Body Mass Index (BMI)

BMI is calculated as weight in kilograms divided by the square of height in meters (kg/m2). It is used to assess the change in body mass relative to height following the 12-week exercise intervention.
