Brief Summary

Background: Weight regain is one of the most common problems in bariatric patients. Although exercise contributes to maintaining weight, there are currently few studies performed on this population. Objective: To know the effects of a high-intensity exercise program applied 3 years after bariatric surgery on body composition and cardiovascular risk factors. Methods: A 37-month follow-up was performed on 21 patients who underwent bariatric surgery, in which periodic body composition was evaluated. At month 37, participants were divided into an experimental group (EG) and a control group (CG). The EG performed a 5-months of a supervised exercise program. At this point physical fitness, glycemia and cholesterolemia were also evaluated in the EG. Finally, the EG repeated the evaluations 2-months after the end of the program.

Outcome Measures

Primary Outcomes (7)

  • Change from Baseline Body Composition at 5 months

    Body mass index (BMI) was calculated according to the formula: total weight in kilograms divided by squared height in meters (kg·m-2). Participants performed the assessment with an empty bladder. Bioimpedance analysis (Tanita, TBF 300A, Tokyo, Japan) was used to establish body weight and body composition.

    Baseline and 5 months, between 8:00 AM and 9:00 AM.

  • Change from Baseline waist and hip circumference at 5 months

    The ISAK (International Society for the Advancement of Kinanthropometry) protocol was used to assess waist and hip circumference

    Baseline and 5 months, between 8:00 AM and 9:00 AM.

  • Change from Baseline Systolic and Diastolic Blood pressure at 5 months

    Blood pressure was measured using a digital sphygmomanometer (Microlife WatchBP Home, Heerbrugg, Switzerland), according to established recommendations

    Baseline and 5 months, between 8:00 AM and 9:00 AM.

  • Change from Baseline Capillary Blood Samples at 5 months

    Capillary blood samples were taken to analyse blood glucose and TC using a portable multi-analyser (Accutrend GCT, Roche Diagnostics, Mannheim, Germany)

    Baseline and 5 months, between 8:00 AM and 9:00 AM.. Measurements only performed at the experimental group

  • Change from Baseline Cardiorespiratory Fitness at 5 months

    he peak oxygen uptake (VO2peak) was determined on a cycle ergometer (Technogym Bike Med, Technogym, Gambettola, Italy), using an Oxycon Pro gas analysis system (Jaeger, Friedberg, Germany) by adapted protocol from Achten. The protocol had two phases: a) a first phase in which the participants performed a 4-minute warm-up at 40 watts (W), followed by increases of 20 W every 3 minutes, maintaining a cadence of 60 rotations per minute (RPM) during the whole phase; and, b) a second phase that started when the respiratory exchange ratio reached 1.0, and which was aimed to determine the VO2peak. This phase consisted of increments of 20 W every minute, maintaining a cadence between 70-80 RPM, until volitional fatigue. The VO2peak was calculated as the average of the highest 30 seconds of VO2. The VO2peak was expressed in absolute values (VO2peak ABS) and normalized to total body weight (VO2peak/BW) and fat-free mass (VO2peak/FFM).

    Baseline and 5 months, between 8:00 AM and 9:00 AM. Measurements only performed at the experimental group

  • Change from Baseline Cardiovascular Risk at 5 months

    The SCORE risk charts of the European Society of Cardiology were used to calculate CVR. The formula to calculate CVR estimates the 10-year coronary risk using Total Cholesterol, systolic blood pressure, gender, age, and smoking status. The underlying survival probability, S0, is given by: S(age)={S0(age)}exp(w) S(age)={S0(age)}exp(w) S(age+10)={S0(age+10)}exp(w)S(age+10)={S0(age+10)}exp(w) Where w=βchol(cholesterol-6)+βSBP(SBP-120)+βsmoker(current)w=βchol(cholesterol-6)+βSBP(SBP-120)+βsmoker(current) For each cause, calculate the 10-year survival probability based on the survival probability for the person's current age and their age in 10 years time: S10(age)=S(age+10)/S(age)S10(age)=S(age+10)/S(age) Calculate the 10-year risk for each end-point as Risk10=1-S10(age)Risk10=1-S10(age) The scale range ordered by the 10-year risk of fatal cardiovascular desease are: 15% and over, between 10%-14%, between 5%-9%, Between 3%-4%, 2%, 1%, under 1%.

    Baseline and 5 months, between 8:00 AM and 9:00 AM.

  • Change from Baseline Health Status at 5 months

    The health-related quality of life was measured by the Short Form Health Survey 36 (SF-36), in its version adapted to the Spanish context. This questionnaire measures physical and mental health through 8 scales, the scores of which are transformed to values between 0-100 points, with the highest scores meaning a better function. These 8 scales are grouped into two summary components, the physical summary component, and the mental summary component, which were calculated according to the reference values of the Spanish population, with a mean of 50 and a standard deviation of 10.

    Baseline and 5 months, between 8:00 AM and 9:00 AM. Measurements only performed at the experimental group
