4.2.2.3 REACTION TIMES
Main Parameters
Start type: Indicates what type of reaction the test must assess, that is:
“Visual stimulus”: on the PC screen a red circle becomes green after a random period of
time; the athlete must ‘react’ to this stimulus (for example, by jumping)
“Acoustic stimulus”: the reaction stimulus is a sound emitted by the PC (using either an
internal loudspeaker or a sound board) after a random period of time.
“Visual/Acoustic stimulus”: the visual (red/green circle) and the acoustic stimuli (beep
from the PC) alternate randomly
“External impulse”: the start to calculate the reaction time is given by a device (e.g. a
start horn or a start button) connected to the jack sockets
Start: indicates if at the beginning of the test the athlete must be ‘inside the area’ of the
bars or ‘outside the area’
Minimum pause: minimum pause time in minutes:seconds between one test and
another (the pause will have this minimum value, but being random it will almost always
be longer)
Number of repetitions: indicates how many repetitions (from 1 to 99) the test must
consist of
Sequence type: the sequence can be ‘Automatic’ (the test repetitions follow each other
automatically) or ‘Manual’ (at the end of each repetition the start of the next test must
be confirmed)
Stop type: this can only happen by ‘Status change’
Secondary Parameters
Minimum contact time [ms]: see above
Minimum flight time [ms]: see above
Maximum flight time [ms]: see above
Reaction time range [ms]: indicates the time frame in milliseconds within which the
reaction signal must be given randomly.
