Context: Reaction time (RT) is the time taken by an individual to respond suitably and quickly to an appropriate stimulus. It is an objective indicator of the ability of the central nervous system to receive information and coordinate the most appropriate response. It is an important part of inherent balance response in a human being. Our sensory faculties of vision, hearing, and their respective RTs form the basis of our feedback mechanisms required for balance. Both are important factors in fall prevention strategies for the elderly. Physical exercises have innumerable benefits that are well documented except the possible effects on RT. This study is designed to see immediate effects of submaximal exercises on visual RT in healthy adults. Aim and Objectives: The aim of this article is to study the immediate effect of submaximal aerobic exercises on visual RT in healthy adults. Settings and Design: The study was a clinical trial with pre-test-post-test design conducted in community centers with convenient sampling. Materials and Methods: One hundred healthy adults in the age group of 18–55 years were selected. RT at rest was assessed using Inquisit 4.0 by Millisecond Software. There was 30 min of aerobic exercise in the form of walking with 70% heart rate response as submaximal aerobic exercise. Immediately after the RT was noted, analysis of data was done using the paired t-test. Results: There was a statistically significant reduction in visual RT after exercise from 293.16 to 272.78 ms (P < 0.01). Conclusion: Submaximal aerobic exercises reduce the visual RT immediately.
