Resumen
Background: obesity and lower physical fitness levels in children are related to the development of cardiometabolic risk factors. Objective: to determine the relationship between health-related physical fitness and physical activity levels, blood pressure, and anthropometric parameters for different weight statuses of Chilean schoolchildren. Material and methods: the participants were 272 girls and 333 boys having a mean age of 12.00 ± 1.23 years. Maximal oxygen consumption (VO 2 max), standing long jump test (SLJ), handgrip strength, physical activity (PA) levels, systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), waist circumference (WC) and body fat (BF) were measured. To establish the relationship between the variables, partial correlations adjusted by sex were carried out and the Chi-square test was applied to compare the proportions between groups. Results: VO 2 max (p < 0.001) was higher in schoolchildren of normal weight. SBP and DBP were higher in obese schoolchildren (p < 0.001). Physical fitness was inversely related to SBP: VO 2 max (r = -0.26, p < 0.001), SLJ (r = -0.11, p = 0.007) and handgrip strength (r = -0.10, p = 0.021), and had a positive relationship with PA: VO 2 max (r = 0.31, p < 0.001), SLJ (r = 0.18, p < 0.001), and handgrip strength (r = 0.26, p < 0.001). Moreover, VO 2 max and SLJ were inversely related to BMI and WC (p < 0.05). The group of obese schoolchildren contained the highest percentage of individuals with hypertension (p < 0.001). Conclusion: the results obtained in this study show that physical fitness has an inverse relationship with SBP and a positive relationship with PA levels. Besides, cardiorespiratory fitness (CRF) and SLJ are inversely associated with the predictors of risk factors for cardiovascular diseases. Finally, obese children presented lower physical fitness and included a higher proportion of individuals with hypertension.
