Background:
Bariatric surgery is an alternative to the obesity treatment.
Aim:
To compare anthropometric variables such as body composition and physical
fitness of those who performed Roux-en-Y gastric bypass.
Methods:
Were evaluated 108 women. They were subdivided in three groups: those who
performed the bariatric surgery by private health insurance (SAS, n=36); by
the public health care (SUS, n=36), and an equivalent group which did not
perform the surgery (NO, n=36). Were performed physical fitness,
anthropometric and body composition tests. Was evaluated the level of
physical activity during the leisure period.
Results:
Statistically significant differences were observed between the groups
sedentary operated (n=28) and sedentary non-operated (n=13) on anthropometry
and fat percentage, being the highest indexes in the group operated.
Conclusion:
The level of physical activity showed a positive influence related to
anthropometric variables, body composition of the individuals who performed
the bariatric surgery when compared to the ones non-operated.
Bariatric surgery (BS) causes an exacerbated loss of body weight and fat, and can promote changes in other body tissues such as bone tissue. The aim of this study was to compare the profile of serum and urinary bone markers and bone mineral density (BMD) of active and sedentary patients after BS. The sample consisted of 89 patients, of both sexes, who underwent BS through the gastric bypass in Roux-Y, between years 2003 and 2013. Anthropometry, body composition, spine and femur BMD was evaluated by dual energy x-ray absormetry (DEXA), as well as biochemical variables through serum collected for the dosage of calcium, osteocalcin and PTH levels, and also 24-hours urine for deoxypyridinoline and calcium. The level of leisure-time physical activity was assessed by questionnaire. Statistical significance was set at 5%. The average age of active and sedentary groups was [51.76 (9.66)] and [47.06 (12.16)] and body mass index [34.98 (6.90)] and [29,26 (5.92)], respectively. There are statistically significant differences in osteocalcin levels between groups (p = 0.021), as well as small effect size observed in the following variables: BMD of the total femur, osteocalcin, deoxypyridinoline and serum calcium (respectively d = 0:36; d = 0:39; d = 00:41 d = 0.3). The incorporation of an active lifestyle demonstrated a positive impact on circulating levels of osteocalcin and other bone parameters, thereby indicating a possible preservation of BMD during the aging process.
The aim of this study was to investigate whether the effects of a multidisciplinary intervention on cardiorespiratory fitness are maintained after 6-month follow-up in adolescents with obesity. One-hundred and seven adolescents with obesity were intentionally allocated in two groups: experimental or control. Adolescents in experimental group underwent a multidisciplinary intervention (supervised aerobic exercise, psychological, nutritional, and clinical counseling). Cardiorespiratory fitness (direct gas analysis), body composition (dual-energy-DXA), anthropometry and blood lipids were measured before intervention (baseline), at the end of the 24-week intervention (post-intervention) and six months after the end of the intervention (follow-up). Cardiorespiratory fitness reduced in control group with no changes in experimental group, and these differences were maintained in the follow-up assessment (control group: 24.2±4.4 ml.kg -1 .min -1 to 22.6±4.9 ml.kg -1 .min -1 ; follow-up: 22.6±4.9 ml.kg -1 .min -1 vs. experimental group: 28.0±4.0 ml.kg -1 .min -1 to 29.7±4.0 ml.kg -1 .min -1 ; follow-up: 28.9±5.7 ml.kg -1 .min -1 ). Reductions in z-score body mass index (BMI) and increases HDL-C after multidisciplinary intervention were maintained after a 6-month follow-up. In conclusion, the benefits of a multidisciplinary intervention on cardiorespiratory fitness, BMI and blood lipids are maintained after a 6-month follow-up. These findings indicate that multidisciplinary interventions produce long-term health consequences on cardiorespiratory fitness. Reinforcing the importance of lifestyle changes as a therapeutic approach for the treatment of obesity in adolescents.
