Introduction: Obesity in adolescence is associated with severe health complications. Objective: To analyze possible associations among body mass index (BMI), body composition, and biochemical profiles of overweight or obese adolescents. Methods: The study was carried out between 2017 and 2020 and included 132 adolescents aged 10 to 18 years. The following variables were analyzed: BMI, fat-free mass (FFM), body fat mass (BFM), skeletal muscle mass (SMM), body fat percentage (%BF), waist-to-hip ratio (WHR), lean mass index (LMI), fat mass index (FMI), and fat-to-lean mass ratio (FMR), as well as total cholesterol (TC), high-density lipoprotein (HDL-c), low-density lipoprotein (LDL-c) and glutamicoxaloacetic transaminase (TGO). The variables were compared between the sexes, and correlated among them, assuming a p<0.05. Results: Higher values were identified for height, LBM, FFM, and SMM in the male group (p<0.05). On the other hand, higher values were identified for the %BF and FMI in the female group (p<0.05). The female, male, and general groups showed significant correlations between BMI and FMR (r = 0.69, 0.74, and 0.69, respectively; all with p<0.05), BMI and FFM (r = 0.44, 0.67, and 0.49, respectively; all with p<0.05),BMI and SMM (r = 0.44, 0.68, and 0.50, respectively; all with p<0.05), and BMI and %BF (r = 0.40, 0.54, and 0.47, respectively; all with p<0.05). In the general group, BMI and HDL levels were correlated (r = −0.18; p=0.04). The BFM and WHR showed a predictive effect for TC; WHR and %BF showed a predictive effect for LDL concentrations, and %BF had a predictive effect for TGO (p<0.05). Conclusions: The differences between the sexes was expected. It was possible to verify that BMI, body composition, and biochemical measures show an interrela tionship between them, such as with a worsening of anthro pometric and body composition indicators associated with worst biochemical parameters, e.g., lower HDL-c and higher TC, LDL-c, and TGO. Thus, public policies are indispensable for combating obesity and related comorbidities in the early phases of life. [ABSTRACT FROM AUTHOR]

Background: Obesity is a chronic, non-communicable, multifactorial disease that different governmental and non-governmental organizations consider a pandemic. It has even been reported as the disease to be combated in the 21st century. Purpose: This study aimed to investigate the effects of a multi-professional intervention with an online component (hybrid - some activities were performed in person, and others were conducted on the internet) on the morphological and cardiorespiratory parameters of overweight or obese females after 6 and 12 weeks of intervention. Methods: Seventeen females between 40 and 59 years of age were included in the final analyses. Data were gathered at 6 and 12 weeks. The interventions were performed for 12 weeks by a team made up of physical education professionals (3x a week), physical therapists (3x a week), nutritionists (1x a week), and psychologists (1x a week). Physical exercises by physical education professionals and physical therapists were conducted in person. In addition, nutritional and psychological group therapy sessions were conducted online through Google Meet. Results: There was a significant reduction (p<0.05) in body fat mass and body fat percentage. The Bruce test with direct spirometric (metabolic gas analyzer) analysis indicated a significant increase (p<0.05) in distance and duration after 12 weeks of intervention. However, there were no observed differences for peak oxygen consumption, blood pressure, body mass, and body mass index (p>0.05) after the training program. Conclusion: The proposed intervention model (i.e., exercises using body weight and accessories, together with nutritional and psychological interventions online) effectively reduced body fat and improved health-related physical fitness parameters in overweight or obese females after 12 weeks.

Introduction: Background: we aimed to investigate the isolated effect of tele-exercises (TE) and their combined effect with nutritional coaching (NC) on health-related parameters of overweight and obese individuals. Methods: forty-one overweight (body mass index ≥ 25 kg/m2) and obese (body mass index ≥ 30 kg/m2) women were randomly assigned to the experimental groups: TE (n = 20) or TE+NC (n = 21). TE was applied 3 days/week in both groups, while TE+NC also received NC 1 day/week. Anthropometric, body composition, and exercise capacity-related outcomes, quality of life, and eating behavior were assessed before and after 8 weeks of the intervention. Results: a significant main time effect (p < 0.01) was detected for flexibility, isometric muscle strength and dynamic muscle endurance, but no main group effect was noted (p > 0.05). On the other hand, neither a significant main time nor group effect (p > 0.05) was detected in the anthropometric and body composition measures, quality of life, or eating behavior. Similarly, no significant between-group difference was observed in the absolute or relative change analysis (all comparisons, p > 0.05). Conclusions: an 8-week TE program enhanced exercise capacity, but did not impact anthropometric or body composition-related outcomes. The combination of NC+TE did not have a clinical advantage in the management of overweight and obesity. [ABSTRACT FROM AUTHOR]
