Objective: To analyze performance trajectories according to age, sex, and bodyweight class among Brazilian Para powerlifting (PP) athletes and to compare these patterns with those observed in their international counterparts. Method: Retrospective cohort study. Results: Performance data from Brazilian National Championships (2017-2025) were analyzed, including weight lifted, age, sex, and bodyweight class; the analyses of age and age at peak performance additionally incorporated data from regional Meetings. Across the study period, several bodyweight classes showed positive correlations between weight lifted and competition year, indicating a general tendency toward performance improvement, particularly among female athletes (r=0.46; p<0.001). In male athletes, the overall correlation was weaker (r=0.26; p<0.001), with significant improvements observed mainly in the up to 49.0 kg, up to 80.0 kg, and over 107.0 kg categories. The age profile of competitors remained relatively stable throughout competition years, with isolated exceptions in specific bodyweight classes. Linear mixed-effects models indicated that peak performance generally occurred between the late twenties and the fifth decade of life, with most male bodyweight classes peaking between 27 and 42 years, while female athletes showed greater variability, reaching up to 52.5 years in one category. The time required to reach peak performance after the first final participation ranged from approximately 3 to 6 years in male athletes and 4 to 7 years in female athletes. Conclusion: Brazilian PP athletes demonstrate overall improvements in lifted weight across recent competition cycles, with a stable age structure and peak performance typically occurring in mature adulthood. These patterns are broadly consistent with those reported for international athletes and provide reference values that may support athlete development, performance monitoring, and long-term planning in PP.
