Normative values for the physical fitness of Mexican police officers (POs) by sex and age are scarce. This study describes physical performance percentiles by sex and age group and developed percentile values for POs of northeastern Mexico. A retrospective analysis was conducted on database of 7,519 men and 1,050 women aged 20–59 years. Fitness assessments included anthropometric measures, handgrip strength, Abalakov vertical jump, agility circuit, and 1,000-m run. Officers aged 20–29 outperformed other groups in all tests, except for grip strength, which peaked in the 30–39 group. In both sexes, fitness declined with age. Percentile tables by sex and age offer benchmarks to support performance standards, guide targeted physical activity programs and inform future research on Mexican POs.
