Effect of water- versus land-based exercise training as a component of a multidisciplinary intervention program for overweight and obese adolescents.

To compare water- versus land-based exercise programs, as part of a multidisciplinary intervention, on physical fitness and health-related quality of life in overweight and obese adolescents. A total of 151 overweight and obese adolescents (age: 13.2±1.8years) were divided into: 1) a water-based intervention (WB; n=28); 2) a land-based intervention (LB; n=57); and 3) a control group (CG; n=66). Anthropometric measures, body composition, flexibility, abdominal strength/endurance, cardiorespiratory fitness and health-related quality of life were assessed prior and by the end of a 16-week intervention. Both the water- and land-based interventions were part of a multidisciplinary program focusing on behavioral changes. Fat Mass (%) was significantly reduced in both intervention groups and a higher progression was observed in the WB group (-9.8±7.2% versus -6.1±6.2%; p<0.05 for pre-to-post changes within-groups). However, LB increased more abdominal strength than WB (69.6±165.8% versus 53.4±83.4%; p<0.05) and significantly increased social (19.7±88.8%), psychosocial (5.1±15.1%) and total score (6.3±14.8%), which was observed in neither WB nor CG. The intervention groups did not change body weight (WB: -1.7±5.3%; LB: 0.1±3.4%; p>0.05 for both groups) and increased (p<0.05) fat-free mass (WB: 4.6±4.0%; LB: 4.4±4.1%), VO2max (WB: 9.3±7.8%; LB: 11.0±13.4%), and physical dimension of quality of life (WB: 9.2±17.2%; LB: 8.9±18.0%) differently of what was observed in CG. The physical dimension improvement observed in the land-based and water-based samples was associated with decreased percentage fat mass (r=0.282 and 0.229; p<0.05). We suggest water- and land-based physical exercises within a multidisciplinary program promote similar improvements in body composition, physical fitness and health-related quality of life in overweight and obese adolescents.

THE RELATION AMONG THE PHYSICAL ACTIVITY LEVEL DURING LEISURE TIME, ANTHROPOMETRY, BODY COMPOSITION, AND PHYSICAL FITNESS OF WOMEN UNDERWENT OF BARIATRIC SURGERY AND AN EQUIVALENT GROUP WITH NO SURGERY

ABSTRACT 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.
