4.4.2 AGILITY
With this type of test, the Witty + Witty·SEM system becomes a tool to have the athlete perform speed &
agility exercises, where the objective is to “turn off” the traffic light by approaching the proximity sensor with
a hand (or foot, a racquet or other body parts).
It is obvious that multiple Witty·SEM traffic lights must be used that, after receiving the test parameters, will
turn on/off according to a sequence pre-set by the user or randomly depending on the mode. The traffic
lights can be positioned differently (on tripods, on magnetic supports, on suction cups on the ground, etc.)
depending on the selected exercise.
If you do not want the athlete to come near the traffic light but rather trigger the passage through a “gate”,
it is possible to combine a photocells with a traffic light using a C-bracket and connecting them to a cable (the
same way as with a double photocell, see chap. 2.2.3).
