This study analyzed age-related peak performance in judo athletes with visual impairments across five Paralympic Games editions, focusing on sex, weight categories, sport classes, and competitive achievement. Data were collected from the official results books of the Athens 2004 to Tokyo 2020 + 1 Games, including 479 athletes (212 females, 267 males). The analysis examined factors such as the Paralympic edition, sex, competitive achievement, weight category, and sport class. Results revealed that the peak performance age was 29 years for males and 28 years for females, with no significant difference between sexes. However, significant differences were found in age by weight category for both sexes (females: p = 0.005; males: p = 0.006) and by sport class for males (p = 0.022). Additionally, age varied significantly between Paralympic editions for both females (p < 0.001) and males (p = 0.014). The majority of athletes in both groups were aged up to 30 years (females: p = 0.002; males: p = 0.027). The study concluded that age at peak performance in judo for athletes with visual impairments is significantly influenced by weight categories (both groups), sport classes (males only), and the specific Paralympic edition (both groups). Most athletes reached their peak performance around 30 years old.
