Purpose: to propose predictive models for relative handgrip strength (RHS) in school adolescents, in addition to comparing anthropometric measurements and performance tests among adolescents, considering their body mass index (BMI). Methods: data from 100 adolescents between 13 and 16 years were analyzed regarding anthropometric measurements, physical performance through the absolute and relative horizontal impulsion test (AHI; RHI), and handgrip strength. Predictive models were developed considering height, sex, body mass index, and physical performance. Results: eutrophic adolescents had significantly higher RHS, AHI, and RHI when compared to overweight/obese adolescents (P<0.001). Height (β=0.305; P<0.001) and AHI (β=0.222; P=0.045) were positively associated with RHS, while female sex (β=-0.311; P=0.001) and BMI (β=-0.277; P=0.004) decreased this measure. Conclusion: overweight/obese adolescents have greater absolute strength but not relative strength to normal-weight adolescents. Height and AHI are positively associated with RHS, while female gender and BMI decrease this measure. These markers are easy to use to identify physical, functional, and health indicators in adolescents.
