Efeitos da caminhada aquática sobre aspectos antropométricos e metabólicos em jovens obesos

Abstract

-Water-based exercise has been recommended for obese individuals due to reduced joint load. The aim of this study was to determine the effects of twelve weeks of water walking (WW) with or without nutritional guidance on anthropometric and metabolic variables in young obese individuals. Seventy-three young obese individuals of both genders (10 -16 years) were randomly assigned in one of the three groups: Water walking and nutritional guidance group (WWN; n=23), Water walking group (WW; n=22) and Control group (CG; n=28). Body mass, height and waist circumference were assessed. Body Mass Index z score (BMI-z) was calculated, also analyzing total blood cholesterol levels (TC) and its fractions, high density cholesterol (HDL-C), low density cholesterol (LDL-C), triglycerides (TG) and fasting glucose before and after the training program. A two-way repeated-measures analysis of variance (ANOVA) was applied to compare groups and post hoc Tukey`s test was used for multiple-comparison in case of significant differences. Analysis of covariance was applied when differences were detected in the pretest. The significant level was set at p<0.05. The distance per exercise session increased from 377 to 829 meters from beginning to the end of the training period. The lipid profile and fasting glucose did not change after training (p>0.05). Reduction in total cholesterol in the walking group with nutritional guidance was observed (p<0.05). Water walking training can be considered as alternative to improve the physical fitness, being particularly effective for cholesterol reduction when combined with nutritional guidance. Key words: Blood glucose; Body mass index; Food and nutrition education; Lipoproteins; Water walking. Resumo -Exercícios aquáticos são recomendados para pessoas obesas devido a redução do impacto articular. O objetivo deste estudo foi verificar o efeito de um programa de doze semanas de caminhada/corrida aquática em suspensão (CAS), com ou sem orientação nutricional (ON), nas variáveis antropométricas e metabólicas em crianças e adolescentes obesos. Participaram 73 indivíduos de ambos os sexos, faixa etária de 10 a 16 anos, divididos aleatoriamente em três grupos: Grupo CAS e ON (WWN; n=23), Grupo CAS (WW; n=22) e Grupo controle (Controle; n=28). Mensuraram-se massa corporal, estatura e Circunferência Abdominal (CA). Calculou-se o Índice de Massa Corporal escore z (IMC-z) e analisaram-se as concentrações sanguíneas de Colesterol total (CT) e suas frações HDL-colesterol (HDL--C), LDL (LDL-C), triglicerídeos (TG) e a glicemia em jejum antes

A relationship between Single Nucleotide Polymorphism (SNP) in HSD11β1 and ADIPOQ genes and obesity related features in children and adolescents submitted on physical exercises

“…All the participants and their parents or legal guardians signed a Consent Form and this study was approved by the Institutional Ethics Committee of University Federal of Parana. These same individuals were previously analyzed for Leite et al, (2010), Leite et al, (2013), Milano et al, (2013, Lopes et al, (2015), Lopes et al, (2016) and Pizzi et al, (2017), but in distinct context and distinct period of time (LEITE et al, 2010;LEITE et al, 2013;MILANO et al, 2013;LOPES et al, 2015;LOPES et al, 2016;PIZZI et al, 2017). Originally, the children and adolescents were grouped in four different training modalities : Aerobic Training, Water Walking, Combined Training Programme and High-Intensity Interval Training (HIIT).…”

“…Other important modality is the "Aerobic Water Walking Training" and it has been recommended for obese individuals due to reduced joint load, contributing to improve physical fitness and being relevant for cholesterol reduction when combined with nutritional guidance (LOPES et al, 2015). Furthermore, the improvements from aquatic exercise training on glucose and lipids serum measures are very important (DELEVATTI; MARSON; KRUEL, 2015).…”

“…It is possible to verify that lipid profile and obesity are influenced by many factors as nutritional behavior, practice of physical exercise and genetics (QI et al, 2005;GOMES FRAGA;BRAGA GOMES, 2014;OGUNDELE et al, 2017;LUIS et al, 2016;TUREK et al, 2014;DEVANG et al, 2017;GAMBINERI et al, 2011;FICHNA et al, 2017;LOPES et al, 2015).…”
