REACTION TIME

 

Definition

Reaction time is the interval of time it takes for a performer to choose a response to a stimulus and then perform the selected movements. The stimulus is received through the performers sight, hearing or kinaesthetic sense. Reaction time can be quicker if a performer pays attention to relevant cues and also through controlling anxiety. A performer’s reaction time is also shorter if there is only one possible response but longer if there is more than one possible response.

 

Impact on Performance

A skilled performer has a quick reaction time by reacting to a stimulus, selecting response and moving sharply. This quick reaction time can be decisive between winning or losing in an activity. An example of simple reaction time is at the start of the 100m when the starting pistol goes off.  Having good reaction time will allow you to start the 100m as quickly as possible without false starting.  This will give you an instant advantage over other sprinters as it is such a short race/distance. Every millisecond can make the difference between winning and losing the race. A tennis player has a matter of seconds to respond to their oppositions serve. The tennis player must have good reaction time to select movements, respond to the speed, direction and spin of the tennis ball in order to return the serve successfully. In football, when a GK makes a penalty save or the ball rebounds of the woodwork the striker is usually the first player to react and convert the rebound. If the defending team do not react quickly enough they will concede a goal.  An example of choice reaction time is dribbling a basketball down court during a game with passing options wide, forward or having the option to drive for the basket.  Under the pressure of time and space you must be able to react to the changing environment as quickly as possible.
