Abstract Resume

Background: Weight excess is a major contributor to poor risk profiles among youth. Whilst obesity and overweight are associated with increased cardiometabolic risk in adolescents,
moderate to high levels of cardiorespiratory fitness are also associated with a reduction in clustering of cardiometabolic risk factors. The simultaneous presence of high triglycerides levels (TG) and
increased waist circumference (WC) is called hypertriglyceridemic waist (HW) phenotype, an important diagnostic tool for cardiovascular risk. Adolescents with weight excess have a greater chance to
present this phenotype. The aim of this study was to analyze the impact of VO²max in HW phenotype and its components in adolescents with weight excess.


Methods: This is a cross-sectional study in which 140 adolescents (14 and 18 years of age), beginners in a multidisciplinary intervention were assessed. They were divided by sex: male
(n=57) and female (n=83). Both groups underwent an assessment of body mass index (BMI), WC, and TG. The presence of HW phenotype was assessed according to the criteria established by Esmaillzadeh et
al. (2006) for adolescents concurrently having serum triglyceride concentrations ≥110 mg/dL and a WC equal to or greater than the 90th percentile for their age and sex (FERNANDEZ et al., 2004). It was
held descriptive statistics (mean, standard deviation and frequency distribution) and inferential (Mann Whitney U test) to observe the results. Significance was set at P<0.05.


Results: The profile analysis of the participants showed that, there was no statistical difference for age and BMI between the sexes, but male adolescents had significantly higher
values of WC and TG compared to their counterparts. Regarding the impact of VO²max on the HW phenotype and its variables, the findings indicated that there is a significant difference between the
means of VO²max of males adolescent with and without altered CC (p≤0.001), as well as the presence or absence of the HW phenotype (p≤0.001). In these adolescents,  VO²máx mean was higher among those
with WC values (54.4%) within the normal range (37,6 ± 5,3ml/kg/ min vs. 32,0 ± 4,0ml/kg/min) and were not diagnosed (78,9%) as having the HW phenotype (36,2 ± 5,4ml/kg/min vs. 30,8 ± 3,2ml/kg/min).
There were no statistical differences between the VO²max mean of female adolescents for all variables (WC p=0,270; TG p=0,938; HW phenotype p=0,428).


Conclusions: The findings indicate that the cardiorespiratory fitness may influence the HW phenotype and its components in males, but not in female adolescents. This suggests that a
high cardiorespiratory fitness may give a security to the cardiometabolic risk alterations in male adolescents. Therefore, obesity treatment interventions should develop cardiorespiratory fitness,
besides healthy habits of physical activity and nutrition.
