Reaction Time is defined as?

• A. Time between presentation of stimulus and onset of movement
• B. Ex: 100m and badminton
• C. Ability to exercise for long periods of time
• D. Range of movement at a joint

Answer: (C)

Reaction time is the time gap between the presentation of a stimulus and the onset of a movement. It measures how quickly you process the cue and start moving. The other ideas refer to different concepts: endurance is about sustaining activity, giving sport examples isn’t a definition, and range of movement describes how far a joint can move. In practice, reaction time can be improved by training perceptual speed, decision making, and motor readiness, leading to a faster start after the signal.
