The Groningen Reaction Time test is a simple test of reaction time. Participants are required to respond to a light as quickly as possible by pushing the button. This test is part of the protocol for the Groningen Fitness Test for the Elderly.

test purpose: to measure reaction time in elderly persons

equipment required: a specially developed timer, which is connected to a handheld module with a display light in the middle and a button on top, much like a stopwatch.

The reaction time (in milliseconds) is displayed on the timer. The time between the visual signals ranges between 4 and 9 seconds. After three practice trials, 15 trials are recorded.
