Bariatric Surgery and Physical Activity Clinical Trial
Official title:
A Supervised Exercise Program After Bariatric Surgery Avoids Fat-Free Mass Loss And Reduces Cardiovascular Risk Factors
Background: Bariatric surgery (BS) causes large weight reductions and improvements in
cardiovascular risk (CVR), although, there are also decreases in fat-free mass (FFM).
However, the effects of exercise after surgery on these variables remains to be determined.
Methods: 38 patients who underwent BS were divided into two groups: an experimental group
(EG, n = 19) and a control group (CG, n = 19). Body composition, physical fitness, CVR and
CVR factors were assessed in both groups one month after the surgery (T1), at 7 months (T2)
and at 13 months (T3). Between T1 and T2, the EG performed a 6 month monitored aerobic and
resistance combined training.
Forty adults that underwent BS (sleeve gastrectomy and gastric bypass) were invited to participate in the study along two years (between 1-4 patients per month). After the initial interview, two patients refused to participate in the study. The participants provided written informed consent before starting the study. The study was approved by the Ethics Committee of the University in accordance with the Declaration of Helsinki. Participants were divided into two groups (experimental, EG; and control, CG) depending on when the BS was performed. The first 10 patients of each year were the EG (n=19) and the other mine patients were the CG (n=19). A 6-month supervised and individualized program that combined aerobic and resistance training (CART) was only conducted with the EG. Both groups followed a nutritional supervision and were evaluated in 3 different time periods: Test 1 (T1), before the intervention period (approximately 1 month after BS) with no differences in any variable measured; Test 2 (T2), after the intervention period (7 months after BS) and Test 3 (T3) to evaluate a retention period (13 months after BS). The tests included in the evaluation were: blood sample, body composition, blood pressure, physical fitness (cardiorespiratory fitness, isokinetic and isometric strength measures of the lower limbs) and CVR. The test protocols were divided into 3 days: 1) between 8:00 AM and 9:00 AM., a blood sample was collected. 2) 24 hours after, at the same hour, body composition and resting blood pressure were measured. In the afternoon (between 5:00 P.M. and 8:00 P.M.), muscle strength measures were obtained. 3) at least 72 hours after the second testing session day, a cardiorespiratory fitness test was performed. Body composition, blood pressure and strength and cardiovascular tests were conducted at the facilities of the Sports Research Centre (Elche, Spain), in a climatically controlled laboratory, with a temperature between 22-24º and relative air humidity between 45-60%. Before any testing, all participants attended two familiarization sessions to introduce testing procedures and minimize the learning effects over the measures ;
