Background: Normal aging phenomenon is associated with cognitive decline, without any associated pathologies, over the lifespan of an adult. The fluid abilities; attention, processing speed, and executive functions are notably affected, which can hamper the everyday life. Reaction time (RT) test assesses all these abilities. Physical activity has been postulated to have a beneficial effect in the prevention of cognitive decline with aging. Objective: To study the effect of aging on the choice auditory and visual RT in healthy adults and in those performing aerobic exercise. Materials and Methods: The present cross-sectional study was carried out in the Physiology Department, IGMC, Nagpur. Twenty healthy adults and 20 aerobic exercisers were recruited in 3 groups of different age groups; Group 1: 3140 years, Group 2: 4150 years, and Group 3: 5160 yearseach group comprising 20 individuals. RT both with low- and high-frequency sound and with red, green, and indigo color was assessed. Statistical analysis was done using One-way ANOVA. Post-hoc analysis was done by TukeyKrammer test. Statistical value of p
