This statement is true. Reaction time is a skill-related fitness component that refers to the ability of the body to react to external stimuli and make quick decisions on what to do with those stimuli. A good example of this is when your hand accidentally touches the fire of a burning candle. Motor neurons send signals to the brain that trigger a response where you suddenly remove your hand from the source of pain. For exercise activities, reaction time is seen in athletes who are waiting for the gun start.
