Correlation between anthropometric, body composition and maximum oxygen uptake in overweight or obesity adolescents

Resumo

Introduction: Childhood obesity has increased significantly, thus showing a concern regarding the treatment of obesity in childhood and adolescence. Objective: To correlate anthropometric variables, body composition and maximum oxygen consumption (VO2max) in overweight or obese adolescents. Materials and Methods: Cross-sectional, correlational and comparative study with 40 adolescents, separated by sex: (boys n=17 and girls n=23), aged=15.6 +/- 1.1 years. Body Mass Index (BMI) measurements were collected; Waist Circumference (WC); Hip Circumference (HC); Waist -Hip Ratio (WHR); Fat Mass (MG); Lean Mass (MM); Skeletal Muscle Mass (MME); Body Fat Percentage (%F) and VO2max. To estimate body composition, the InBody520 (R) electrical bioimpedance was used. VO2 max was estimated using the Leger and Lambert test (1988). Normality was tested using the ShapiroWilk test. Results: Boys had higher values for WC; WHR; MM; MME and VO2 max (p<0.01), while girls had higher values for %BF (p<0.01). Boys and girls, there were negative correlations (p<0.05) between VO2 max and FM (r=-0.37), VO2 max and %BF (r=-0.63) and positive correlations (p<0.01) between VO2max and LM (r=0.51), VO2 max and MME (r=0.52). In boys, negative correlations (p<0.01) were identified between VO2 max and BMI (r=-0.68), VO2 max and WC (r=-0.64; p<0.01), VO2 max and HC (r=0.62), VO2 max and FM (r=-0.69) and VO2 max and %BF (r=-0.77). Conclusion: There were differences in body composition and VO2 max values between genders. Different anthropometric, body composition and VO 2 max variables are correlated and may increase cardiometabolic risks in overweight or obese male adolescents.
