Reaction Time

Year 12 Physical Eduaction

Reaction Time Definition

Is the time that it takes for the body to react to an external stimulus, from the time the presentation of a stimulus to the onset of a response.

Factor that Affect the Fitness Components

The amount of fast twitch fibers the individual has would affect the ability that person has to react. If the individual has more fast twitch fibres than slow twitch then they are more likely to have the ability to perform better than someone who has more slow twitch.

External distractions and decision-making can mean that reaction time increases. When there is only one possible response reaction time is at its quickest.

2 Recognised Tests

Ruler- Drop reaction test

Light board reaction timer


Ruler- Drop reaction test


One, one meter ruler and a chair


The performer sits on the chair and the tester holds the ruler vertically at the top. the performer places their thumb and index finger either side of the ruler at the 10 cm mark, about 1 cm fromthe ruler. the tester releases the ruler without warning. the performer stops the ruler at quickly as possible.

Norms for Ruler-Drop Test (Centimeters)

Excellent: less than 9.9

Good: 10-20

Average: 21-40

Poor: greater than 40

Training methods to train the fitness components

There is no specific training methods to improve reaction time. If you are a sprinter you would have to practice starts and reacting to the gun. To add to the difficulty and practice race day situations, have a recording of the crowd and play that while practicing the starts.
