The research aimed to compare the anaerobic performance of pubescent and postpubescent wrestlers. Methods: 29 Freestyle and Greco-Roman Wrestlers were part of the study sample, with the following physical characteristics (mean ± SD): age: 14.99±1.83 yrs.-old, body mass: 54.68±16.80kg, height: 161.06±12.78cm, body fat: 12.09±4.11%, BMI: 20.58±3.79 kg/m2, sports experience: 3.66±2.27 years, of the different wrestling clubs of the Barinas State, Venezuela. The qualification of the wrestlers in pubescent and post-pubescent, was performed by evaluating secondary sexual characteristics following Tanner's criteria. Anaerobic performance was measured with the lower and upper body's Wingate test (WAnT). Results: statistically significant differences were reported between the two groups of wrestlers classified by maturity category (pubescent vs. post-pubescent) when compared with the anaerobic performance indices obtained in the Wingate test [Peak Power (PP-Watts and Watts/kg); Average Power (AP-Watts y Watts/kg); Fatigue index (FI-%)] for the lower and upper body. For the PP absolute (Watts) of arms and legs (**p <0.01), PP relative (Watts/kg) of arms and legs (*p <0.05), AP absolute (Watts) of arms and legs (***p <0.001) and the AP relative (Watts/kg) of arms and legs (**p <0.01). Meanwhile, the percentage of fatigability (FI) of both lower and upper body did not show statistically significant differences. Conclusion: the Wingate test for the lower and upper body, performed in isolated form, discriminates the anaerobic performance of adolescent wrestlers in sports training when the maturation categories classify them.
